Using az containerapp logs shows recent logs, but for troubleshooting historical logs, you need to use Log Analytics.
First, retrieve the workspace ID of the Log Analytics.
WORKSPACE_ID=$(az containerapp env show -n $ACA_ENVIRONMENT -g $RESOURCE_GROUP \
--query properties.appLogsConfiguration.logAnalyticsConfiguration.customerId -o tsv)
echo "Workspace ID: $WORKSPACE_ID"
WARNING: The behavior of this command has been altered by the following extension: containerapp
Workspace ID: [REDACTED]Then use az monitor log-analytics query and provide the workspace ID and the container ap pname. The command below retrieves the last 20 log entries.
az monitor log-analytics query -w $WORKSPACE_ID \
--analytics-query "ContainerAppConsoleLogs_CL | where ContainerAppName_s == '$CONTAINER_APP_NAME' | project TimeGenerated, Log_s | order by TimeGenerated desc | take 20" \
-o table
Log_s TableName TimeGenerated
