Monitoring Routers

Monitoring Routers

This chapter describes the various ways in which you can monitor Cisco routers using NSP. This chapter also lists and describes each NSP router status and how to define filters to view routers that match a certain status or are defined to specific group.

This chapter provides information on the following:

Displaying Router Status

You can display a list of all the Cisco routers on your network that are being monitored by NSP. The color in which the service point name of a router is displayed indicates the status of that router.

To view a list of routers being monitored by NSP, on the NSP main menu, position the cursor on the * MGR option, and press Enter. The Router Status panel is displayed.


Figure 4-1: Router Status Panel

The following information is displayed on the Router Status panel:

Taking the Fast Path to Problem Resolution

From the Router Status and Router Status Extended panels, you can select a router and use the F5 function key to have NSP take you to the diagnostic panels most suited to solve the most critical problem affecting the router. For example, if an alert has been received from a router (router is displayed in pink and has an ALERT status), then selecting the router and pressing F5 takes you to the appropriate panel to view the received alerts for that router.

To take the fast path to problem resolution, on the Router Status or Router Status Extended panel, position the cursor on the router for which you want to view status details, and press F5.

Expanding the Status Information

To display additional information about the status of the routers in your network, on the Router Status panel, press F6. The Router Status Extended panel is displayed.


Figure 4-2: Router Status Extended Panel

The following information is displayed on the Router Status Extended Panel:


Note The Router Status panels are not intended for operational monitoring of a specific router. Use the Router Status panels to monitor all the routers in your network and to determine those routers for which you want to view operational information.

Reviewing Status Types

The color in which the service point name of a router is displayed on the Router Status panel indicates the status of that router.

The following table lists the color and meaning of each status.


Table  4-1:
NSP Router Status
Color Status Definition
Green ACTIV NSP can communicate with the router and the router is ready to receive commands.
Red INACT Router has never been activated and cannot generate alerts or receive commands.
Red INOP Router failed when a command was issued perhaps because the router has been made inactive by an operator. If a router is in a inactive state, an SSCP-to-PU session cannot be established. An operator must first activate the router by issuing the SOLVE:Netmaster ACT command.
Red UNKNOWN The router is not defined to VTAM.
Yellow PERF The router is active and NSP has detected a performance-related problem, or an interface configured in the router is down.
Pink ALERT The router is active and through the SOLVE:Netmaster automation table an alert was detected from a resource managed by the router control point.
Turquoise CONCT Router has not been connected to VTAM.
Reverse nnnnn Router is in enable mode.
N/A Blank Indicates there is no information available about the router.

Filtering Routers

The NSP Router Status panel can display status information for up to 144 routers simultaneously. This allows you to view most, if not all, the routers in your network. To display a subset of routers that are of interest to you, you can define viewing filters.

You can define filters based on:

Filtering by Logical Groups

Group filtering allows you to view 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 NSP administrator when the router is defined to NSP. You can identify the group to which a router belongs from the Router Status Extended panel or by viewing the management information data of a router. For information on viewing the management information data of a router, see the "Viewing Router Configuration from the NSP Perspective" section.

Filtering by Status

Status filtering allows you view status for routers that match, or do not match, a specified status. You can choose to display a view that includes or excludes routers that match up to three status types that you specify. For more information on the statuses by which you can filter routers, see the "NSP Router Status" table in the "Reviewing Status Types" section.

Defining a Filter

Filters are defined in your NSP operator profile. If an operator profile has not been created for you by an NSP administrator, you can create one for yourself for filtering purposes. For additional information on operator profiles, see the "Defining Operator Profiles" section of the "Installing and Configuring Native Service Point" chapter.


Note The following procedure can also be used to create an operator profile.

To filter the routers you are viewing on the Router Status and Router Status Extended panels:

Step 1 On NSP menu, position the cursor on the * USER option and press Enter. The Cisco Router User Administration panel is displayed.

For a complete description of the fields on the User Administration panel, see the "Defining Operator Profiles" section of the "Installing and Configuring Native Service Point" chapter.

Step 2 Specify information for the following fields:

Logical groups are defined by an enabled NSP user in the router definition. The logical group or groups to which a router may belong are displayed on the Router Status Extended panel.

Step 3 Press Enter to verify your changes and press F4 to save them.

Step 4 To update the Router Status panel return to the NSP main menu, select the * MGR option, and press Enter.

Refreshing and Resetting Routers

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

If you are an enabled NSP user, you can also release and reset a router from an operator who is logged in to a router in enabled mode or is in a busy state with a router.

To refresh outdated router status information, on the Router Status panel, press F12.

To reset a router, on the Router Status Extended panel, position the cursor over the router you want to reset, and press F8.

Monitoring Router Performance

This section describes the router performance data that is available from NSP. 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 measure the performance of a router:

Setting Router Monitoring and Threshold Values

If you are an NSP administrator, you can set the monitoring intervals and CPU and memory thresholds in the NSP setup. Specifying CPU and memory thresholds determines the percentage of the CPU and free memory being used that, when exceeded, places a "P" in the Xtended column on the Router Status Extended panel to flag the router with degraded performance, alters the status of the router to PERF, and turns the SPname of the router to yellow.

To change the NSP monitoring and threshold values:

Step 1 On the NSP main menu, position the cursor on the * SETUP option and press Enter. The NSP Router Management Setup panel is displayed.


Figure 4-8: NSP Router Management Setup Panel

Step 2 Specify information in the following fields:

Step 3 Press Enter to verify your changes and F4 to save the NSP setup.


Note For a complete description of the fields located on the NSP Router Management Setup panel, see the "Configuring NSP" section in the "Installing and Configuring Native Service Point" chapter.

Gathering and Viewing Router Performance Data

Once you have set the monitoring interval and CPU and memory threshold levels, NSP will measure the performance of the routers in your network using those values. The results are archived in the Router Performance History data set. If you are an NSP administrator, you can set the record wrap counts for the data set in the NSP setup. Any NSP user can view the records archived for a specific router on the Router Performance History panel.

Gathering Router Performance Data

To set the Router Performance History wrap counts:

Step 1 On the NSP main menu, position the cursor on the * SETUP option and press Enter. The NSP Router Management Setup panel is displayed.

Step 2 Press F8 to display the second NSP Router Management Setup panel and F8 again. The Router Management Constants Setup panel is displayed.


Figure 4-9: Router Management Constants Setup Panel

Step 3 Position the cursor in the Router Performance History Value field in the MAX Record Count section and type the number of performance records you want to collect. A valid range is a 1- or 2-digit number. The default is 48.

Caution The wrap counts are set on a per router basis. When these values are changed after initializing NSP, they only apply to new routers or interfaces defined to NSP. The only method of applying changed wrap counts to previously defined routers and interfaces is to delete the router definition and redefine the router to NSP.

Viewing Router Performance Data

To view performance history records for a specific router:

Step 1 On the Router Status panel, position the cursor on the router for which you want view performance data and press Enter. The popup menu is displayed.

Step 2 In the field located at the top of the popup menu, type A and press Enter. The archived performance data for the router you selected is displayed.

Logging in to Routers and Issuing Commands

You can use the NSP Router Command Interface panel to connect to and issue commands to a router that you would normally have to issue via a telnet session with a router. However, NSP does restrict the use of certain commands such as TELNET.

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


Note The commands that you can successfully issue from the Router Command Interface panel are based on your authority level as defined in your operator profile.

To issue commands to a router using the Router Command Interface:

Step 1 On the NSP main menu, press Tab to move to the Service Point Name field.

Step 2 Type in the service point name of the router and press Enter. The Router Command Interface panel is displayed.
