This VM extension runs PerfInsights script that collects useful diagnostics information for troubleshooting IaaS performance issues on this Azure VM. We recommend that you work with your CSS contact to select the right performance scenario to help troubleshoot the performance issue you are having.

Based on the performance scenario, you might end up running one or more components mentioned below:

• Performance diagnostic traces for CPU, Disk and memory operations
• PerfMon for performance counters
• XPerf for advanced storage performance analysis
• Netmon traces for advanced network analysis: Network Monitor traces help detect problems on the network. Trace data contains network traffic information at the frame level and hence all non-encrypted data is visible in a trace.

This script will create a zip file that includes the collected log files and findings that will be uploaded to Microsoft support automatically or by you directly. Additionally, this data is uploaded to the specified storage account, shared using SAS (Shared Access Signatures) and available for download for 30 days. This data will be stored by Microsoft for a maximum of 90 days after your issue is resolved and will be used and retained consistent with the standards set forth at the Microsoft Trust Center.
