### Monitor Container Apps with SigNoz
Collect key Container App metrics and view them with an out of the box dashboard.
To collect logs, you need to make sure that you have chosen "Azure Monitor" as the logging option for Container's App Environment.
Note: This integration ingests logs for only "ContainerAppConsoleLogs" and "ContainerAppSystemLogs" diagnostic settings categories.
