Monitor Azure Container Apps metrics

Azure Monitor collects metric data from your container app at regular intervals to help you gain insights into the performance and health of your container app.

The metrics explorer in the Azure portal allows you to visualize the data. You can also retrieve raw metric data through the Azure CLI and Azure PowerShell cmdlets.

Available metrics

Container Apps provides these basic metrics.

Title	Dimensions	Description	Metric ID	Unit
CPU Usage	Replica, Revision	CPU consumed by the container app, in nano cores (1,000,000,000 nanocores = 1 core)	UsageNanoCores	nanocores
Memory Working Set Bytes	Replica, Revision	Container app working set memory used in bytes	WorkingSetBytes	bytes
Network In Bytes	Replica, Revision	Network received bytes	RxBytes	bytes
Network Out Bytes	Replica, Revision	Network transmitted bytes	TxBytes	bytes
Replica count	Revision	Number of active replicas	Replicas	n/a
Replica Restart Count	Replica, Revision	Restarts count of container app replicas	RestartCount	n/a
Requests	Replica, Revision, Status Code, Status Code Category	Requests processed	Requests	n/a
Reserved Cores	Revision	Number of reserved cores for container app revisions	CoresQuotaUsed	n/a
Resiliency Connection Timeouts	Revision	Total connection timeouts	ResiliencyConnectTimeouts	n/a
Resiliency Ejected Hosts	Revision	Number of currently ejected hosts	ResiliencyEjectedHosts	n/a
Resiliency Ejections Aborted	Revision	Number of ejections aborted due to the max ejection %	ResiliencyEjectionsAborted	n/a
Resiliency Request Retries	Revision	Total request retries	ResiliencyRequestRetries	n/a
Resiliency Request Timeouts	Revision	Total requests that timed out waiting for a response	ResiliencyRequestTimeouts	n/a
Resiliency Requests Pending Connection Pool	Replica	Total requests pending a connection pool connection	ResiliencyRequestsPendingConnectionPool	n/a
Total Reserved Cores	None	Total cores reserved for the container app	TotalCoresQuotaUsed	n/a

The metrics namespace is microsoft.app/containerapps.

Note

Replica restart count is the aggregate restart count over the specified time range, not the number of restarts that occurred at a point in time.

More runtime specific metrics are available, Java metrics.

Metrics snapshots

Select the Monitoring tab on your app's Overview page to display charts showing your container app's current CPU, memory, and network utilization.

From this view, you can pin one or more charts to your dashboard or select a chart to open it in the metrics explorer.

Using metrics explorer

The Azure Monitor metrics explorer lets you create charts from metric data to help you analyze your container app's resource and network usage over time. You can pin charts to a dashboard or in a shared workbook.

1. Open the metrics explorer in the Azure portal by selecting Metrics from the sidebar menu on your container app's page. To learn more about metrics explorer, see Analyze metrics with Azure Monitor metrics explorer.

2. Create a chart by selecting Metric. You can modify the chart by changing aggregation, adding more metrics, changing time ranges and intervals, adding filters, and applying splitting.

Add filters

Optionally, you can create filters to limit the data shown based on revisions and replicas.

To create a filter:

1. Select Add filter.

2. Select a revision or replica from the Property list.

3. Select values from the Value list.

Split metrics

When your chart contains a single metric, you can choose to split the metric information by revision or replica with the exceptions:

• The Replica count metric can only split by revision.
• The Requests metric can also be split on the status code and status code category.

To split by revision or replica:

1. Select Apply splitting.

2. From the Values drop-down list, select Revision or Replica.

3. You can set the limit of the number of revisions or replicas to display in the chart. The default value is 10.

4. You can set sort order to Ascending or Descending. The default value is Descending.

Add scopes

You can add more scopes to view metrics across multiple container apps.
