Alloy Service Runtime Error: invalid memory address or nil pointer dereference

Grafana Alloy
1

Hi,

i want to monitor several Windows Server over Grafana Cloud.
For that i used connections/add-new-connection/windows-exporter?page=alloy

  1. Test Alloy Connection works.
  2. Appended Integration and Logs to config.alloy (no individual edits)
  3. Restarted Service
  4. Test connection: No metrics were found for this integration.
  5. Server (2022 21H2) Event Viewer Application Error:

a)
runtime error: invalid memory address or nil pointer dereference
[signal 0xc0000005 code=0x0 addr=0x0 pc=0x7b78d33]

goroutine 828 [running]:

b)
level=error msg=“service exited with error” err=“exit status 2” exit_code=2

That is probably the reason why no metrics were found.
Does anyone know how to fix this?

Hello! Apologies - I believe you were affected by a bug in version 1.4.1 of Alloy. Please try using version 1.4.2. It should not have this problem.
