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 CMCCs and DSPUs) when you set up the router monitoring options.
For information on setting up router-specific management options, see the section "Setting Up the Router Monitoring Options" in this chapter.
Complete the following tasks to set up ISM to manage routers and their resources:
Step 1 On the ISM main menu panel (Figure 5-1), press the Tab key until the cursor is located on the * SETUP option and press Enter.

Step 6 In the Action Type option, do one of the following tasks to enable router monitoring and the other setup options that you specified:
Step 7 To confirm the options that you selected, press Enter.
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:
DIS router_service_point
Step 2 Verify that the router is active to VTAM as shown in Figure 5-3. Your display might vary slightly depending upon the configuration of your router.
Step 3 To initiate ISM's discovery of the router, go to the ISM main menu panel (Figure 5-4) and press the Tab key until the cursor is positioned on the Service Point Name field for the * CMD New Router Contact option. Type the service point name of the router that you want to add and press Enter.

You can set up router monitoring for an individual router using one of the following methods:
For more information on updating individual router definitions, see the section "Setting Up Individual Router Monitoring Options" in this chapter.
The amount of time that the ISM monitoring autotask waits to contact routers to collect statistics and update status is specified on a global basis for all routers on the second ISM Router Management Setup panel (Figure 5-11). The default monitoring interval is 15 minutes.
You can modify this monitoring interval for all routers on the ISM Router Management Setup panel. Or, if you want to balance the monitoring load among a large number of routers being managed by ISM, you can assign your routers to groups and use the ISM Scheduler application to set up monitoring intervals for every router group.
For more information about setting up the router monitoring intervals, see the sections "Setting Up ISM Router Management" and "Setting Up the Router Monitoring Schedules" in the "Setting Up the ISM Environment" chapter.
If threshold settings are specified, it means that ISM indicates a performance alert (status is PERF) for the router when the following conditions occur:
You can set up the CPU and memory thresholds for all routers on the second ISM Router Management Setup panel (Figure 5-10). For more information about setting up the global router management options, see the section "Setting Up ISM Router Management" in the "Setting Up the ISM Environment" chapter.
For more information on updating individual router definitions, see the section "Setting Up Individual Router Monitoring Options" in this chapter.
For more information about enabling the ISM Interface Monitoring application and selecting the types of interfaces for ISM to monitor, see the section "Setting Up ISM Router Management" in the "Setting Up the ISM Environment" chapter.
You can set up router interface archiving for an individual router using one of the following methods:
For more information on updating individual router definitions, see the section "Setting Up Individual Router Monitoring Options" in this chapter. For more information about monitoring interfaces, see the "Monitoring Interfaces" chapter.
If you assign a router to more than one group and also set up the ISM Scheduler application, then ISM monitors the router according to the monitoring interval associated with the first group to which the router is assigned. The order in which you specify a group ID for a router affects the implementation of group scheduling.
You can assign routers to management groups using one of the following methods:
For more information on updating individual router definitions, see the section "Setting Up Individual Router Monitoring Options" in this chapter.
You must be an operator with ISM enable authority to enable router alert generation or modify other ISM rules.

You can disable archiving of history and performance data using one of the following methods:
For more information on updating individual router definitions, see the section "Setting Up Individual Router Monitoring Options" in this chapter.
You can remove the history and performance records for an individual router from the history database using the Reset Performance History option on the ISM Router Administration panel (Figure 5-8). When you enable the Reset Performance History option, the history records are removed from the database when you press F4 to update.
You can use this option to update the record wrap counts when ISM reinitializes the history file. The record wrap counts are specified on the Router Management Constants Setup panel (Figure 3-5). For more information on specifying the wrap counts, see the section "Setting Up ISM Router Management" in the "Setting Up the ISM Environment" chapter.
Complete the following tasks to delete history and performance records for an individual router:
Step 1 On the ISM Router Administration panel (Figure 5-8), type Yes in the Reset Performance History option.
Step 2 In the Change Type option, type 2 for Update.
Step 3 To confirm the options that you selected, press Enter.
Step 4 To delete the performance history data, press F4.
You can also change the maximum number of records that the 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 reset the history for an individual router or interface. After you reset 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 section "Deleting History and Performance Records" in this chapter. 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 global constants, see the section "Setting Up ISM Router Management" in the "Setting Up the ISM Environment" chapter.
ISM provides two primary panels where you can monitor the status of your routers:
Use the ISM Status Summary panel (Figure 5-13) to monitor the overall status of all your routers by type of condition. The ISM Status Summary panel uses a color-coded display to indicate different types of status conditions. New alerts are shown in a colored box. After routers with new alerts have been viewed by an operator, or if you leave the ISM Status Summary panel, the colored box is removed. The number in the column representing the number of routers in that condition will remain color-coded unless the status condition has been removed.
You can perform the following operations to access other information when monitoring routers using the ISM Status Summary panel:
To view router status and diagnose router problems, use the Router Status panel (Figure 5-14). To access the Router Status panel, use the * MGR option on the ISM main menu panel or select a router on the ISM Status Summary panel and press Enter.
You can perform the following tasks on the Router Status panel:
To display additional information about the status of the routers in your network from the Router Status panel (Figure 5-14), press F9. The Router Status Extended panel is displayed (Figure 5-15).
The Router Status Extended panel provides the following additional information about the routers on the network:
The color of the service point name of a router on the ISM Status Summary panel (Figure 5-13) or Router Status panel (Figure 5-14) indicates the condition of that router.
Table 5-1 lists the color and definition of each status.
| Color | Status | Definition |
| Green | ACTIV | ISM can communicate with the router and the router is ready to receive commands. |
| Red | CONCT | Router is not connected to VTAM. |
| Red | INOP | Router failed to respond when a RUNCMD was issued, perhaps because the router has been made inactive by an operator. If a router is in an inactive state, a System Services Control Point (SSCP)-to-PU session cannot be established. An operator must first activate the router by issuing the NetView ACT command. |
| Yellow | PERF | The router is active, but ISM has detected a performance-related problem for the CPU or memory utilization thresholds, or an interface configured in the router is down. |
| Pink | ALERT | The router is active, but an alert was detected through the NetView automation table for a router resource managed by the router control point. |
| Turquoise | INVALID | Service point is unknown to VTAM. VTAM definition does not exist. |
| Turquoise | INACT | An operator has inactivated the router in VTAM. |
| Reverse | nnnnn | An operator is enabled to the router. |
| Blue | NOMON | Router monitoring is disabled for the router. |
ISM provides a powerful diagnostic function that you can use to obtain information about the most critical problem affecting the router. From the Router Status panel (Figure 5-14), the Router Status with Options panel (Figure 5-7), or the Router Status Extended panel (Figure 5-15), you can press F5 to display the diagnostic panel that ISM determines is best-suited to solve the router's most critical problem.
For example, if an alert has been received from a router (router is displayed in pink and has an ALERT status), then you can select the router and press F5 to display the appropriate panel to view the received alerts for that router. If the problem is a hardware related problem, then ISM might open NPDA to show hardware status information from NetView.
To quickly diagnose router problems on the Router Status panel or Router Status with Options panel, position the cursor on the router that you want to diagnose and press F5.
You can apply filters based upon the following criteria:
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 filter routers by groups. For more information about assigning routers to groups, see the section "Assigning Routers to Management Groups" in this chapter.
To include filters for up to two router groups on the ISM status panels, complete the following steps:
Step 1 From the ISM main menu panel (Figure 5-1), press the Tab key until the cursor is positioned on the * USER option and press Enter.
The ISM User Administration panel is displayed (Figure 5-16).
Timesaver To go directly to the ISM User Administration panel, type the ismuser command at any ISM command prompt and press Enter.
Step 2 In the Group Filters option, type Y.
Step 3 In the Group 1 and Group 2 options, specify the router group names that you want to include when viewing the ISM router status displays.
Step 4 In the Change Type option, type 2 for Update.
Step 5 In the Action Type option, do one of the following:
Step 6 To confirm the options that you selected, press Enter.
Step 7 To update the ISM user definition according to the Change Type and Action Type options that you selected, press F4.
Step 8 View the ISM status panels to see only the resources defined to the groups that you selected.
To view a logical group of routers from the Router Status or Router Status Extended panels, in the Group/Router/Alias option at the top of the panel, type the name of the router groups that you want to view and press Enter.
The routers that belong to the filter groups that you specified are displayed.
Figure 5-17 and Figure 5-18 show examples of filtering for routers assigned to the group LAB1.
Tips
You can determine the group to which a router belongs from the Router Status Extended panel (Figure 5-15) or by viewing the administration data of a router (Figure 5-8 and Figure 5-9).
Status filtering allows you to view status for routers that match, or do not match, a specified status. You can specify filtering of routers that match up to three different status types, and then display a Router Status panel view that includes or excludes those routers. For more information on the statuses by which you can filter routers, see Table 5-1.
To include or exclude routers that match the filter criteria (up to three status types) for viewing on the ISM status panels, complete the following steps:
Step 1 From the ISM main menu panel, press the Tab key until the cursor is positioned on the * USER option and press Enter.
The ISM User Administration panel is displayed.
