1 week ago Hi @kemats, We completed and merged the PR with the fixes for the resource utilization monitor - https://github.com/microsoft/azure-pipelines-agent/pull/4803.
In scope of this PR we:
- Fixed the issue with the incorrect CPU metrics for Linux/Windows/MacOS
- Added metrics catching between debug and warning monitors, which decrease the amount of metric requests and improve performance
- Switched the Windows metrics methods to use .Net ManagementObjectSearcher queries instead of direct calls of the deprecated
WMIC.exewhich will resolve the issue with thread pool exhaustion. - Replaced synchronous metric methods with asynchronous requests that support cancellation to avoid the issue with the blocking requests
- And other minor improvements that will improve overall performance and will provide more accurate resource usage data
The changes will be available on the next agent rollout. We'll inform you after deployment will be completed.
Describe your question
The resource utilization warnings feature is currently disabled by removing $(AZP_ENABLE_RESOURCE_UTILIZATION_WARNINGS) agent knob as temporary workaround for performance degradation issue https://github.com/microsoft/azure-pipelines-agent/issues/4781. Please update here for users' awareness once the issue is fixed and the feature is re-enabled.
