12:18 PMDon’t think we have tested properly in AKS. But the only reason this might not be working is that the filereader cannot access files in the node.
can you manually check if you can access files present in

can you manually check if you can access files present in
/var/log/pods/*/*/*.log https://github.com/SigNoz/charts/blob/5d322fbf515a3af07b4ea8102be6ca4b8f16654b/charts/k8s-infra/values.yaml#L86 through the collector podcc Prashant

12:24 PMthere is no file in this path /var/log/pods//*/.log , i have checked inside the pods
nitya-signoz
nitya-signoz
12:25 PMIt means that AKS stores logs in a different path, I will have to check on this.
or maybe more permissions are required
