Servicing and Troubleshooting

This appendix provides procedural and reference information that you can use to determine and resolve problems you might experience while using ISM.

This appendix includes information on the following:

• Tracing ISM Data

• Restoring the ISM Base Administrator Profile

• Viewing SNMP Variables

• Viewing NetView Timers

Tracing ISM Data

Sometimes a problem cannot be traced to a specific source. ISM provides the following trace utility commands that you can use to isolate problems:

The trace facilities that you enable using the ismaid command affect only the operator ID under which you issue the command. The following sections provide examples of the output received when using any of the trace utilities.

---

Note   The actual data you receive at your site can vary depending on the routines ISM is processing when you run the trace.

---

Tracing the ISM Internal Data Flow

The ISM Internal Data Flow utility traces the internal data flow of the processes occurring in ISM. You turn on the ISM Internal Data Flow utility by issuing the following command:

To turn off the utility, issue the ismaid debug off command.

The following example shows the data returned to your console once you turn on the ISM debug trace facility. The example provided is the internal tracing of the data flow that occurs when an operator issues the ismistat command.

Tracing CLISTs

The ISM CLIST Trace utility traces different ISM CLIST elements based on the keyword you specify when you turn on the utility. Table C-2 explains this utility's commands and options.

Tracing Routine Entries and Exits

The ISM Flow Trace utility traces the entries and exits of all ISM routines.

The following example shows the type of data that is returned to your console as ISM routines are processed when the ismaid trflow on command is issued. To turn off the utility, issue the ismaid trflow off command.

Turning Off Tracing

If you have enabled all of the ISM trace utilities (debug, ctrace, and trflow), you can turn off each utility individually, or you can issue a command that turns off all tracing. For information on turning off a trace utility individually, see the command provided in the appropriate section. To turn off all ISM trace utilities running, issue the ismaid off command.

Restoring the ISM Base Administrator Profile

ISM provides a backup ISM administrator profile that can be used by a system administrator to recreate an ISM administrator profile if all existing profiles are deleted accidentally. If all ISM administrator profiles are deleted, an ISM user does not have the authority to modify the ISM management environment or to assign user authority levels.

If the base ISM administrator profile is deleted, complete the following steps to create a new profile:

Step 2   Log on to NetView as the ISMADMIN operator.

Step 3   Create several ISM administrator profiles as described in Chapter 5, "Configuring ISM," in the CiscoWorks Blue Internetwork Status Monitor Installation Guide. Creating these profiles ensures the availability of additional ISM administrator-level profiles for backup.

Displaying Variables

There are ISM commands to display each set of control variables.

ISMVARS displays all common variables used in all ISM functions. Enter this command from the NetView command line or from the ISM Administration menu panel. The ISM Common Globals panel (Figure C-1) shows sample output for the ISMVARS display.

ISM's control variables are described in Table C-3 through Table C-6.

---

Note   From the Resource Status with Options panel, press PF9 to show all variables associated with a resource.

---

ISM uses address letters followed by an index number to build each variable. Table C-7 shows the name of each variable, its description and its contents.

Display interface variables by selecting the Display Interfaces option in the ISM Interface Operation Options panel. Table C-8 describes sample output for this option.

Viewing SNMP Variables

To view SNMP variables, on the SNMP for ISM Management Setup panel (Figure 3-8), press PF10. The ISM Common Globals for SNMP (Figure C-2) is displayed.

Viewing NetView Timers

To view NetView timers based on the current scheduler options, on the ISM Schedule Setup panel (Figure 3-9), press PF10. The List NetView Timers panel (Figure C-3) is displayed.
