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:
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.
ISM's architecture provides two layers of router management control options---global and individual:
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.
ISM provides two primary panels where you can monitor the status of 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.
The actions displayed on this panel are the most commonly used ones. To display a complete list of actions available, type ? next to a router and press Enter. You can then select an action from this list to apply to the router.
There are different types of functions available by using the actions on the ISM : Router List panel:
Table 5-1 describes the administration functions available from the ISM : Router List panel. See also the "Adding and Updating Router Definitions" section.
Task | Action | Result |
---|---|---|
Browse a router's definition | B or S | The ISM : Router Administration panel (Figure 5-3) is displayed for the selected router, allowing you to browse its definition. |
Delete a router | D (E) | A message is displayed, requesting confirmation of the delete. |

S | Serial interface not in desired state. |
TO | Token Ring interface not in desired state. |
TU | Tunnel interface not in desired state. |
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.
The ISM : Router Administration panel is displayed (Figure 5-3) in Add mode.
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.
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.
The default router monitoring interval is 15 minutes (00:15). Cisco recommends 2 hours (02:00).
If threshold settings are specified, it means that ISM indicates a performance alert (status of PERF) for the router when the following conditions occur:
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.
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.
For more information on setting up router alert generation, see the "Setting Up Router Management Parameters" section.
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.
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.
You can apply filters based upon the following criteria:
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.
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).
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).
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.
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.
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.
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.
You can refresh or check the status of a router from the ISM : Router List panel.
