AKS Log Analytics Workspace records the log for only 3 hours problem

If ContainerLogV2 only shows data for the same 3-hour window every day, I would first prove whether logs are not being collected, or whether they are being collected but not landing in that table.

A few quick checks:

ContainerLogV2 | summarize count(), min(_TimeReceived), max(_TimeReceived) by bin(TimeGenerated, 1h)

Then check the AMA logs daemonset:

kubectl get ds ama-logs -n kube-system kubectl get pods -n kube-system -l rsName=ama-logs -o wide

If the agent pods restart or go unhealthy around the time logging stops, start there. If the agent is healthy and other tables like KubePodInventory keep updating all day, then I would look at the Container Insights config/ConfigMap, namespace filters, table retention, or ingestion throttling.

The fixed daily window is the clue. That usually points to either an agent/config schedule issue or a query/table setting, not random pod logging behavior.
