Procedure Diagnostic and corrective actions 1. Does the system command run correctly from a command line? v Yes: Go to the next step. v No: Verify that the command you typed in is correct. 2. Is the length of the command within the limit for your operating system? v Yes: Go to the next step. v No: The command cannot be executed on this platform. You might be able to write a wrapper script to issue the command. 3. Are the required user type and environment variables correct? v Yes: Go to the next step. v No: Include the set command in the shell script or batch script and redirect the output to a file. Review the file afterwards to show which variables are being used. 4. Collect the monitoring agent operations log, which shows whether reflex automation occurred. A monitoring server message log also confirms which error occurred. 5. Correct the identified problem. High CPU usage on a distributed system You can encounter a problem that CPU usage is high on a distributed system. Symptoms of the problem: v Performance degrades or availability is lost because of high processing in an application or a computer. v No data is returned in the portal client and the collector log contains the text string Open Probe pipe error. See "Resolving Oracle DB Agent problems corrective actions" on page 32. v Situations alert you frequently about a managed system cycling between online and offline. See "Resolving firewall problems - corrective actions" on page 31. Diagnosing high CPU usage on a distributed system You can diagnose that CPU usage is high on a distributed system by determining whether a monitoring component, application, or process running on the system might be the cause of the problem. Also, you can use the ITMSUPER tools, such as the Connectivity tool to provide more information. About this task To diagnose that CPU usage is high on a distributed system, perform the following steps: Procedure Preliminary diagnostics 1. Determine whether an IBM Tivoli Monitoring component is the root cause. Another application or process running on the system might be causing high CPU usage. Chapter 3. Common problem solving 29

Procedure

Diagnostic and corrective actions

Does the system command run correctly from a command line?

Yes: Go to the next step.

No: Verify that the command you typed in is correct.

Is the length of the command within the limit for your operating system?

Yes: Go to the next step.

No: The command cannot be executed on this platform. You might be able to

write a wrapper script to issue the command.

Are the required user type and environment variables correct?

Yes: Go to the next step.

No: Include the

set

command in the shell script or batch script and redirect

the output to a file. Review the file afterwards to show which variables are

being used.

Collect the monitoring agent operations log, which shows whether reflex

automation occurred. A monitoring server message log also confirms which

error occurred.

Correct the identified problem.

High CPU usage on a distributed system

You can encounter a problem that CPU usage is high on a distributed system.

Symptoms of the problem:

Performance degrades or availability is lost because of high processing in an

application or a computer.

No data is returned in the portal client and the collector log contains the text

string

Open Probe pipe error

. See “Resolving Oracle DB Agent problems -

corrective actions” on page 32.

Situations alert you frequently about a managed system cycling between online

and offline. See “Resolving firewall problems - corrective actions” on page 31.

Diagnosing high CPU usage on a distributed system

You can diagnose that CPU usage is high on a distributed system by determining

whether a monitoring component, application, or process running on the system

might be the cause of the problem. Also, you can use the ITMSUPER tools, such as

the Connectivity tool to provide more information.

About this task

To diagnose that CPU usage is high on a distributed system, perform the following

steps:

Procedure

Preliminary diagnostics

Determine whether an IBM Tivoli Monitoring component is the root cause.

Another application or process running on the system might be causing high

CPU usage.
