How to troubleshoot high CPU usage caused by the Patch Management agent plugin?
Work through the following procedures to pinpoint the cause for high CPU usage on the client caused by the Patch Management agent plugin:
- Disable Firewall
- Disable Virus Software
- Disable Scanning of the machine
- Disable each Solution that was installed from Altiris
- Disable all other items that are not part of the machine OS that could contribute
Begin with turning each of these back on - beginning with the Patch Management Agent. Observe the behavior of the CPU usage and allow for time to try each software enabled. There should be an increase in CPU usage when the conflicting software is enabled and that can be further troubleshot as needed.
Advisory: Exclusions for Altiris Agent through Antivirus are detailed on KM: TECH174641
Another good tool is Process Monitor. Found at: http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx.
Work through the following to use the Process Monitor from Microsoft:
- Open ProcMon tool on the client
- Select the Magnifying Glass and that will stop the profile
- Select the Edit > Clear Display and Get the AeXPatchUtil.exe ready to run with /i - Outlined on KB HOWTO10560Select the Magnifying Glass to start the profile, and execute the AeXPatchUtil.exe with /i
- Wait about one minute and then Select the Magnifying Glass to stop the profile
- Select File > Export, and export the data is needed to be transfered to another media
Note: One instance of this anomaly was caused by the client failing to download a package. Client logs displayed invalid software update package and this was causing the scan to run with high CPU. See also KM: TECH46342.
