Missing IIS Counter (perflibWebService)

[Michel Drevet]

Hello,

I'm trying to expose some IIS metrics however some are missing, especially the CurrentConnections.
Especially, it seems that everything related to perflibWebService is missing.

When running the exporter, I face this following error : ts=2024-02-13T10:21:38.184Z caller=unmarshal.go:69 level=debug collector=iis msg="missing counter \"% 503 HTTP Response Sent\", have [Total Threads Metadata Cache Flushes % 404 HTTP Response Sent WebSocket Connection Attempts / Sec WebSocket Connections Accepted / Sec Total HTTP Requests Served Total Flushed URIs Total URIs Cached Metadata Cache Hits WebSocket Active Requests WebSocket Connections Rejected / Sec File Cache Hits Current URIs Cached Output Cache Total Misses % 403 HTTP Response Sent Maximum Threads Count File Cache Flushes Metadata Cache Misses / sec Maximum File Cache Memory Usage Output Cache Current Items Total Flushed Files File Cache Misses / sec Uri Cache Hits / sec _Base Metadata Cache Misses Output Cache Hits / sec Total Metadata Cached Total Flushed Metadata % 401 HTTP Response Sent Active Requests URI Cache Hits Active Threads Count Output Cache Total Flushed Items Requests / Sec Output Cache Total Hits Output Cache Current Memory Usage % 500 HTTP Response Sent Current File Cache Memory Usage Current Files Cached Metadata Cache Hits / sec URI Cache Misses Output Cache Current Flushed Items Total Files Cached Uri Cache Misses / sec URI Cache Flushes Current Metadata Cached Output Cache Total Flushes File Cache Hits / sec Output Cache Misses / sec File Cache Misses Active Flushed Entries]"

However, these counter does exist when running Get-Counter :

I have already :

• Resynched the counter WINMGMT.EXE /RESYNCPERF
• Restarted the Performance logs and Alerts Service Get-Service -Name "pla" | Restart-Service -Verbose
  However, I have not Restarted the WMI service itself (refering this issue : #64)

Thank you for your help!

Apologies for the delayed response; the error indicates the % 503 HTTP Response Sent counter is missing. Is that counter present when checking the counters with Get-Counter?
