Azure Function App Monitoring

Starter

Professional

Bleemeo collects metrics for Azure Function Apps via Azure Monitor (Microsoft.Web/sites namespace). Metrics are polled every 1 minute.

Metrics

Metric	Description
function_executions	Number of function executions
function_execution_units	Execution units consumed (execution time multiplied by memory used, in MB-milliseconds)
function_errors	Number of requests resulting in an HTTP 5xx error
function_requests	Total number of requests
function_avg_response_time	Average response time in seconds

Note

function_avg_response_time reports no data for periods without any incoming request.

Caution

function_avg_response_time is based on Azure’s AverageResponseTime metric, which Microsoft has marked as deprecated in favor of HttpResponseTime (“Response Time”). This metric may stop reporting data at any time.

Permissions

Requires the Monitoring Reader role and the Microsoft.Insights resource provider registered on the subscription — see Permissions Summary.

Estimated Azure Cost

$0.432/month per batch of up to 50 Function Apps in the same region (1 Azure Monitor API call per minute) — see Estimated Azure Costs.
