CDM is sending internal alarms regarding CheckMemInfo - GetMemInfo failed (temporarily out of resources)

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

You may get spurious alarm messages that have the following text:

cdm:InternalAlarm: Unable to get Memory data (temporarily out of resources)
cdm:InternalAlarm: Unable to get CPU data (error)
cdm:InternalAlarm: Unable to get Memory data (error)

Environment

Cdm 5.x or above

AIX Systems:

Windows Systems

Cause

On AIX machines the commands CDM will run will timeout before completing. Changing the timeout will resolve the issue.

On some systems incorrect NTP settings can cause this issue

On Windows Systems the performance counters may have been corrupted

Resolution

On AIX Systems:

If you are receiving CPU or Memory alarms - add the following keys in raw configure with values between 30 to 250

Example 

For CPU

<cpu> section of cdm

sliced_cpu_interval = 30

For MEMORY

<memory> section of cdm

sliced_memory_interval = 30

On Windows systems:

Work with the system administrator to rebuild the performance counters.  CDM probe uses these Windows components to collect the metrics.
If needed, go through the below link for “how to manually rebuild the performance counter library values “.

On both systems:

Check that NTP settings are correct and accurate. A few seconds of drift may cause this issue.
