Monitoring Routers

Monitoring Routers

ISM provides a number of functions that allow you to effectively monitor and manage your router network environment from the mainframe. You can use ISM to monitor the status of all your routers, using a powerful interface that allows you to specify performance thresholds and monitoring intervals, and assign routers to management groups.

ISM monitors router status according to the monitoring intervals and performance thresholds that you can specify and provides alerts for problem conditions. In addition, ISM enables you to quickly go to the panel that provides you with the best information about the detected router condition so that you can quickly diagnose the source of the problem.

This chapter describes the following tasks to help you monitor your network routers in ISM:

Setting Up ISM Router Management

ISM's default setup enables the Router Management application for all routers known to ISM. When the Router Management application is enabled ISM will monitor routers and their associated resources (interfaces, CMCCs, and DSPUs), and you can use the ISM : Status Summary panel and the ISM : Router List panel to manage your router resources. You can also monitor the interface, CMCC, and DSPU resources associated with a router.


Note DSPU resources are not actively monitored by ISM. For more information about monitoring DSPU resources, see the
"Monitoring DSPU Resources" chapter.

Once you have enabled the Router Management application in ISM, you can disable monitoring of individual routers (including their associated interfaces, CMCCs, and DSPUs) when you set up the router monitoring options.


Note You might want to disable the Router Management application in instances when you have set up ISM as a focal point domain, where the ISM program in your local SOLVE:Netmaster domain is set up to access only the router resources of a remote SOLVE:Netmaster domain. For more information about setting up ISM for focal point management, see the "Setting Up ISM System Parameters" section.

ISM's architecture provides two layers of router management control options---global and individual:


Note For you to set up the router monitoring options, your ISM user profile must have enable authority. For information on setting up ISM's user profiles, see the "Defining the ISM User Profiles" section.

For information on setting up global router management options, see the "Setting Up Router Management Parameters" section.

For information on setting up router-specific management options, see the "Updating Individual Router Monitoring Options" section.

Displaying Router Status

ISM provides two primary panels where you can monitor the status of your routers:

For further information about using the ISM : Status Summary panel to monitor routers, see Chapter 4, "Monitoring Resources in ISM."

Using the Router List to Manage Your Routers

The ISM : Router List panel (Figure 5-1) shows all routers currently defined to ISM, with details of their current status and settings. This panel is the basis of your day-to-day router management activities. To define a new router to ISM, use the F4 (Add) function (see the "Adding and Updating Router Definitions" section).

To access the ISM : Router List panel, type R in the Select Option field on the ISM : Monitoring Menu panel and press Enter.

Adding and Updating Router Definitions

Before you can monitor routers in ISM, you must have a management definition set up for the router in ISM.


Note If you are an existing NSP 2.0 customer and you have converted your router definitions using the EXEC CISCALL ACTION=MIGRATE procedure, then your current router definitions are available in ISM 3.0. You can access your existing router resource definitions and update them from within ISM 3.0. For more information about router resource definitions see the
"Updating Individual Router Monitoring Options" section in this chapter. For more information about converting your router definitions, see the chapter "Migrating From NSP Release 2.0" in the CiscoWorks Blue Internetwork Status Monitor for SOLVE:Netmaster Installation Guide.

Adding Router Definitions

If the router is already connected to the mainframe and communicating with VTAM, you can choose one of two options to create the new router definition:

When ISM detects a new router, it recognizes and establishes the VTAM definition member and major node for the router record in ISM. This information is necessary for successful monitoring of the router.

Use the following procedure to create a new router definition for a router that has not already been discovered by ISM:

Step 1 On the ISM : Router List panel (Figure 5-2), press F4.


Figure 5-2: ISM : Router List Panel


The ISM : Router Administration panel is displayed (Figure 5-3) in Add mode.


Figure 5-3: ISM : Router Administration Panel


Step 2 Enter details in the two mandatory Router Information input fields: Service Point Name and Description.

For information about fields on this panel, press F1.

Step 3 To enable or disable monitoring, type Yes or No in the mandatory Router Parameters input field: Monitor?.

Step 4 To enable or disable router archiving or interface archiving, type Yes or No in the two mandatory Router Parameters input fields:

Step 5 Optionally, type values in the Router IP Address field.

Step 6 Optionally, to allocate this router to one or more groups for monitoring, type the name of one, two, or three groups in the Group(s) field(s).

If you do not specify a group, the router is added to the default group.

Step 7 Optionally, to set individual thresholds for monitoring this router, type the required threshold values in the CPU Threshold and Memory Threshold fields.

The default thresholds are the global thresholds set on the Parameter Administration panels.

Step 8 Press F3 to file the router details.

ISM populates the remaining fields. ISM then discovers the new router, together with its current resources (interfaces, CMCCs, and DSPUs).

Step 9 Pressing F3 (in Step 8) exits the panel. To modify the discovered fields, update a record by typing U next to the service point name and press Enter.

Step 10 Type new details in the fields that you want to change.

Step 11 Press F3 to file the router details.

Updating Individual Router Monitoring Options

ISM allows you to set up certain router monitoring options for individual routers. This ability allows you to override certain settings, including CPU and memory performance thresholds, for individual routers.

To set up router monitoring for an individual router, complete the following steps:

Step 1 On the ISM : Router List panel, type U beside the service point name of the router that you want to modify and press Enter.

The ISM : Router Administration panel is displayed (Figure 5-3) in Update mode.

Step 2 To allocate this router to one or more groups for monitoring, type the name of one, two, or three groups in the Group(s) fields.

Step 3 To enable or disable router monitoring for this router, type Yes or No in the Monitor? field.

Step 4 To enable or disable router archiving for this router, type Yes or No in the Router Archiving? field.

Step 5 To enable or disable interface archiving for this router, type Yes or No in the Interface Archiving? field.

Step 6 To set individual thresholds for monitoring this router, type the required threshold values in the CPU Threshold and Memory Threshold fields.

Step 7 Press F3 to file the changes that you have made.

Setting Up the Router Monitoring Interval

The amount of time that the ISM polling waits to contact routers to collect statistics and update status is specified either:

The default router monitoring interval is 15 minutes (00:15). Cisco recommends 2 hours (02:00).

Setting Up the Router CPU and Memory Thresholds

You can modify the CPU and memory thresholds that ISM uses when monitoring routers to issue alerts for CPU and memory performance conditions on a global or individual-router basis. The default threshold settings are 95 percent for CPU utilization and 10 percent free memory. To remove threshold settings, type 0 in the corresponding option. If 0 is set, no alert is created.

If threshold settings are specified, it means that ISM indicates a performance alert (status of PERF) for the router when the following conditions occur:


Note ISM also generates a generic alert in SOLVE:Netmaster's NEWS facility or NetView's NCCF facility if you have enabled the Router Perf/Memory alert option on the ISM : Router Management Parameters panel (see the
"Setting Up Router Management Parameters" section). For more information about enabling alerts to NEWS, see the "Setting Up Router Alert Generation" section.

Setting Up Router Thresholds for All Routers

You can set up the CPU and memory thresholds for all routers on the ISM : Router Management Parameters panel. For more information about setting up the global router management options, see the "Setting Up ISM Management Applications" section.

Overriding Global Router Thresholds for Individual Routers

You can override the router CPU and memory global thresholds that are set up for all routers on an individual-router basis on the ISM : Router Administration panel (Figure 5-3). Type the percentages that you want to update in the CPU Threshold and Memory Threshold options.

For more information on updating individual router definitions, see the "Updating Individual Router Monitoring Options" section.

Setting Up Router Alert Generation

If you want ISM to send generic alerts to SOLVE:Netmaster's NEWS facility for router performance, memory, and status alerts, then you must enable the alert generation rules for routers. Alert generation to NEWS from ISM is disabled by default when ISM is first initialized.

For more information on setting up router alert generation, see the "Setting Up Router Management Parameters" section.

Disabling Router Interface Archiving

If the Interface Monitoring application has been enabled in ISM, then you can enable or disable interface archiving for individual routers in ISM. By default, the Interface Monitoring application is enabled by ISM and interface archiving is enabled for all routers.

For more information about enabling the ISM Interface Monitoring application and selecting the types of interfaces for ISM to monitor, see the "Setting Up ISM Management Applications" section.

You can set up router interface archiving for an individual router on the ISM : Router Administration panel (Figure 5-3). Type Yes or No in the Interface Archiving? field.

For more information about monitoring interfaces, see the "Monitoring Interfaces" chapter.

Diagnosing Problems

ISM provides a powerful diagnostic function that you can use to obtain information about the most critical problem affecting the router. From the ISM : Router List panel (Figure 5-1), you can type DR next to a router and press Enter to display the ISM : Router Diagnosis Actions List for Router panel (Figure 5-4). This panel displays a list of actions that you can perform to diagnose problems with the selected router. The list of actions available varies, depending on the current status and extended status of the router. You can select one or more actions to perform.

The following actions are always provided:

The following actions are provided depending on the extended status:

For example, suppose the selected router is in PERF status with extended status TO E, where:

Then the panel is displayed with the actions shown in Figure 5-1.


Figure 5-4: ISM : Router Diagnosis Actions List for Router Panel


Filtering Routers

The ISM : Router List panel allows you to view status information for all your routers by scrolling forward (F8) or backward (F7). You can also apply filters to display a subset of routers that are of interest to you.

You can apply filters based upon the following criteria:

Filtering by Service Point Name

You can filter the routers that you want to view by using the Service Point Name field on the ISM : Monitoring Menu panel (Figure 5-5).

To filter routers from the ISM : Monitoring Menu panel, in the Service Point Name field, type the beginning characters of the service point name that you want to view, followed by an asterisk (*) (to allow a match for any remaining characters in the name), and press Enter. Only the routers with service point names that begin with the same characters you specified are displayed. For example, to filter the display of all routers beginning with the characters cwb, type cwb* in the Service Point Name field.


Note You can filter by both service point name and group name at the same time.

Filtering by Logical Groups

Group filtering allows you to view the status for logically grouped routers. For example, a group may include all the routers located in a region or department, or those of a particular device type. The group to which a router belongs is assigned by an ISM administrator when the router is defined to ISM, and only an ISM administrator can define router filters by groups. For more information about assigning routers to groups, see the "Assigning Routers to Management Groups" section.

To view a logical group of routers from the ISM : Monitoring Menu panel, complete the following steps:

Step 1 From the ISM : Primary Menu panel, type M in the Select Option field and press Enter. The ISM : Monitoring Menu panel is displayed (Figure 5-5).


Figure 5-5: ISM : Monitoring Menu Panel


Step 2 In the Select Option field, type R.

Step 3 In the Group Name field, specify the router group name for which you want to view routers and press Enter. You can enter a question mark (?) to display a selection list of group names.

The ISM : Router List panel is displayed, listing routers that belong to the filter group that you specified.

Tips

You can determine the group to which a router belongs from the ISM : Router List panel (Figure 5-1) or by viewing the definition of a router (Figure 5-3).


Note You can filter by both service point name and group name at the same time.

Filtering by Status

Status filtering allows you to view the status for routers grouped by status. For example, you may want to include all routers in a particular status, or exclude all routers in a particular status. Do this by defining a status filter on the ISM : Status Filter Details panel (Figure 5-6), as described in the following section.

Updating Your Own Status Filter Details

You can view or update your own status filter details by using the SF action on the ISM : Monitoring Menu panel. To update your status filter details, complete the following steps:

Step 1 On the ISM : Monitoring Menu panel (Figure 5-5), type SF in the Select Option field and press Enter. The ISM : Status Filter Details panel (Figure 5-6) is displayed, showing details for your user ID.


Figure 5-6: ISM : Status Filter Details


Step 2 In the Exclude/Include field, type I or E to indicate whether you are excluding or including routers of the specified status in your monitoring.

Step 3 In one or more Status Filters fields, type the status values that you want to exclude or include.

Refreshing and Resetting Routers

Although ISM automatically updates the status of the routers at the intervals specified by an ISM administrator in the ISM setup, you can manually refresh router status information at any time between those intervals.

Refreshing and Resetting Router Attributes

If you are an enabled ISM user, you can rediscover a router and refresh its attributes (interfaces, CMCCs, and DSPUs). You do this by using the Discover action (CHK) on the ISM : Router List panel.

If you are an enabled ISM user, you can reset a router from an operator who is logged in to a router in enabled mode or who is in a busy state with a router. You do this by using the Reset action (R) on the ISM : Router List panel.

Refreshing and Resetting Router Status

You can refresh or check the status of a router from the ISM : Router List panel.

To refresh outdated router status information on the ISM : Router List panel, press F6.

To reset a router from the ISM : Router List panel, type R next to a router and press Enter. The selected router is reset.

Managing Router Data

If you enable router monitoring, the router history and performance data is stored in its own VSAM database. For each individual router definition, you can perform the following operations on your history and performance data:

Disabling Archiving of Router History and Performance Data

By default, ISM enables router monitoring and archiving of history and performance data, such as CPU and memory utilization statistics. You can disable archiving of router history and performance data for individual routers.

To disable archiving for a router, use the ISM : Router Administration panel (Figure 5-3). Type No in the Interface Archiving option.

For more information on updating individual router definitions, see the "Updating Individual Router Monitoring Options" section.

Deleting History and Performance Records

You can remove the history and performance records for an individual router from the history database using the Delete History function on the ISM : Router Performance History panel (Figure 5-7).

Complete the following tasks to delete router performance history records for an individual router:

Step 1 On the ISM : Router List panel (Figure 5-2), type H beside a router entry and press Enter. The ISM : Router Performance History panel (Figure 5-7) for the selected router is displayed.


Figure 5-7: ISM : Router Performance History Panel


Step 2 On the ISM : Router Performance History panel, press F4.

The ISM : Router Management History Delete panel is displayed.

Step 3 Press F6 to confirm the delete.

ISM displays a message confirming that the router performance history records for the selected router have been deleted.

Changing the Maximum Record Counts

You can change the maximum number of records that each history database contains before overwriting the data contents. The wrap counts are set for all routers and interfaces. When these values are changed after initializing ISM, the new values will apply to new routers and interfaces defined to ISM. You can apply the new values to existing resources if you delete the history for an individual router or interface. After you delete the history records, the next time that the file is initialized the new values will be used.

For more information on resetting the history database, see the "Deleting History and Performance Records" section. Another method of applying changed wrap counts to previously defined routers and interfaces is to delete the router definition and redefine the router to ISM.

For more information about changing the wrap counts, see the "Setting Up ISM Database Parameters" section.

Viewing Router Management Information

There are several ways that you can view the management information for a router. The following sections describe the ways that you can collect and view the configuration of a router:

Viewing Router Status from VTAM

Complete the following tasks to view a router as it is defined in VTAM:

Step 1 On the ISM : Router List panel (Figure 5-1), type V next to the router name and press Enter. The NCS : Node Display panel is displayed (Figure 5-8), showing the router connection as it is defined in VTAM.


Figure 5-8: NCS : Node Display Panel


Step 2 If you want further VTAM information, you can enter VTAM or NCS commands in the input field next to a node. For further information about using these commands, press F1 to view the online help.

Viewing the Router Administration Definition from ISM

Use the ISM : Router List (Figure 5-1) panel to view a router as it is defined in ISM. In the Enter Option field, type S or B next to a router name and press Enter. The ISM : Router Administration panel (Figure 5-3) for the selected router is displayed.

Collecting and Archiving a Router Configuration

If you are an enabled ISM user, you can log in to a router and collect its current configuration. You can also archive the router configuration file that you collect. To collect a current configuration, you must first log in to the router in enable mode. You must know the router password, and if the router is using TACACS+, you must have a user ID defined to TACACS+ to collect a router configuration.

Complete the following tasks to collect the current configuration of a router:

Step 1 On the ISM : Router List panel, type CO next to the router name for which you want to view ISM management information and press Enter. The ISM : Router Configuration Command panel (Figure 5-9) is displayed.


Figure 5-9: ISM : Router Configuration Command Panel


Step 2 In the Command field, type the one of the following codes for the configuration request:

Step 3 In the Password field, type the enable password and press Enter.

When the request has been completed, a message is displayed showing the number of records collected and stored.

Step 4 When you are notified that the router configuration for the router has been saved, press Enter. The configuration you collected is archived.

Step 5 Press F3 to terminate your enabled session to the router.

Viewing Archived Configurations

You can display a list of archived configuration files for a router, view the details of a specific configuration file, and use an archived configuration file for disaster recovery.

Complete the following tasks to display a list of archived configuration files:

Step 1 On the ISM : Router List panel, type CV next to the router name for which you want to view ISM management information and press Enter. The ISM : Configuration Records for Router panel (Figure 5-10) is displayed.


Figure 5-10: ISM : Configuration Records for Router Panel

Figure 5-11: ISM : Router Configuration Details Panel


Step 3 Locate specific details within the router configuration record on this panel by scrolling (press F7, F8, F10, or F11) or by finding text-strings (press F5).

Monitoring Router Performance

This section describes the router performance data that is available from ISM. It explains how to obtain the performance data that is useful in monitoring the performance of a router.

You can use the following methods to monitor the performance of a router:

Setting Router Monitoring and Threshold Values

If you are an ISM administrator, you can set the monitoring intervals and CPU and memory thresholds in the ISM Router Management setup. Specifying a monitoring interval determines the interval (in hours and minutes) when ISM queries and collects performance data from the routers in your network. Specifying CPU and memory thresholds determines the level (expressed as a percentage of the CPU utilization and availability of free memory) that when exceeded will cause ISM to generate an alert. When a performance alert is generated, ISM displays the following indicators:

For more information on setting up the router monitoring and threshold options, see the "Setting Up the Router Monitoring Interval" section and "Setting Up the Router CPU and Memory Thresholds" section.

Viewing Router Performance History

If router monitoring is set to Yes and CPU and memory threshold levels are set, ISM measures the performance of the routers in your network at the specified intervals. The results are archived in the Router Performance History data set. Any ISM user can view the records archived for a specific router on the Router Performance History panel.

To view performance history records for a specific router, type H next to the router's service point name on the ISM : Router List and press Enter. The Router Performance History panel (Figure 5-12) is displayed for the specified router.


Figure 5-12: ISM : Router Performance History Panel


The ISM : Router Performance History panel shows CPU usage and memory usage statistics. Threshold values are shown at the top of the display columns. If thresholds are exceeded, the line containing the record is shown in yellow.

From the ISM : Router Performance History panel you can delete the displayed records from the performance history database. To delete the records for the selected router from the performance history database, press F4 (DelHist). The ISM : Router Management History Delete panel is displayed, prompting you to confirm or cancel your deletion request.


Note Using the DelHist command (F4) deletes all router performance history records for the selected router.

Viewing Alerts and Events

If you have enabled alert generation, alerts generated by a router that is being monitored by ISM are forwarded to the host by the service point configured in the router. You can enable ISM to generate alerts for routers, interfaces, and CMCCs when thresholds are exceeded. For information about enabling alert generation in ISM, see the "Setting Up Router Alert Generation" section.

You can access SOLVE:Netmaster's NEWS facility from within ISM to obtain a list of alerts generated by a specific router or router resource and forwarded to SOLVE:Netmaster. For more information on using SOLVE:Netmaster's NEWS facility, see the SOLVE:Netmaster User's Guide.

Displaying Alerts

To display a list of the most recent alerts in SOLVE:Netmaster's NEWS, type EV next to a service point name on the ISM : Router List and press Enter. The NEWS : Events Review panel is displayed listing the alert records generated by the selected router.


Note Whether or not the alert that generated the ALERT status in ISM is stored in the NEWS database depends on the configuration of NEWS.

For details of how to use SOLVE:Netmaster's NEWS facility to view details of alerts, see the SOLVE:Netmaster User's Guide or press F1 to view the online help for the NEWS panels.

Logging in to Routers and Issuing Commands

You can use the ISM : Command Interface panel to connect to a router and issue commands that you would normally be issued in a Telnet session. However, ISM does not allow the use of certain commands such as telnet.


Note The commands that you can successfully issue from the ISM : Command Interface panel are based on your authority level as defined in your operator profile and on the security implemented in the router.

Commands issued from the ISM : Command Interface panel are optionally written to the SOLVE activity log. The name of the operator who issues a command is also recorded. However, as an ISM security feature, if the issued command requires a password, the password is suppressed and not logged. Also, if the issued command requests router configuration information, all security sensitive data is suppressed and not logged.

Issuing Commands From the ISM : Router List Panel

Complete the following tasks to issue commands to a router from the ISM : Router List panel:

Step 1 On the ISM : Router List panel, type CI next to the service point name of the router and press Enter. The ISM : Command Interface panel (Figure 5-13) is displayed.


Figure 5-13: ISM : Command Interface Panel


Step 2 If you want to execute the command on a remote system, type the remote system ID in the Link Name field.

Step 3 If a password is required for the command that you entered, type the password in the Password field.

Step 4 To specify how output from the router command is to be handled, specify one of the following options:

Step 5 In the Command field, type the router command and press Enter.

The command output is displayed on the panel.

Step 6 To recall the last command that you issued, press F6.

Issuing Router Show Commands

ISM provides a list of commonly used Cisco IOS software show commands that you can use to obtain additional information about a router. These commands are useful for monitoring and problem determination purposes. If you are an ISM administrator, you can add show commands to the ISM : Router Show Commands panel (Figure 5-14).

Showing Router Memory

To execute router show commands that display information about the router's memory configuration, use the ISM : Dump Types List panel. To access the ISM : Dump Types List panel, use the DU option on the ISM : Router List panel.

The following commands are displayed on the ISM : Dump Types List panel (Figure 5-16):

Requesting a Memory Dump and Viewing Stored Memory Dumps

If you want to issue a router memory command to request a memory dump but do not want to view the output yet, you can use the DU option to request a dump and add it to the list of stored dumps. When you want to view it, you can select it from the list of stored dumps.

To request a memory dump and view it later, perform the following steps:

Step 1 On the ISM : Router List panel, type DU next to the service point name of the router for which you want to view ISM management information and press Enter. The ISM : Dump Types List panel is displayed (Figure 5-16) for the selected router.

Step 1 On the ISM : Dump Types List panel, type S next to a memory dump type and press Enter.

ISM executes the corresponding command and stores the output so that it can be viewed from the ISM : Stored Dumps List. It also displays a completion message against the selected dump type, advising how many records have been stored as a result of this dump.

Step 2 When you are ready to view the output of a memory dump, on the ISM : Router List panel, type V next to the service point name of the router for which you want to view ISM management information and press Enter. The ISM : Stored Dumps List is displayed (Figure 5-17).

Step 4 Locate specific details within the command output on this panel by scrolling (press F7, F8, F10, or F11) or by finding text-strings (press F5).

Step 5 To delete a memory dump from the ISM : Stored Dumps List, type D next to a dump and press Enter. A message is displayed, prompting you to confirm or cancel your delete request.

Requesting a Memory Dump for Immediate Viewing

To request a memory dump and view it immediately, perform the following steps:

Step 1 On the ISM : Router List panel, type DU next to the service point name of the router for which you want to view ISM management information and press Enter. The ISM : Dump Types List panel is displayed (Figure 5-16) for the selected router.

Step 2 To request and view a memory dump, type V next to a memory dump type and press Enter. ISM executes the corresponding command.

If the dump finds any records to process, ISM displays the command output on a memory dump panel. The format of this panel varies, depending on the type of memory dump. For example, selecting a Memory Free dump displays an ISM : Memory Free Dump panel (Figure 5-18) for the selected router.

If the dump finds no records to process, ISM displays a completion message against the selected dump type, advising that the number of records stored as a result of this dump is zero.
