This section describes Cloud Functions metrics delivered to Monitoring.

The metric name is written to the name label.

All Cloud Functions metrics share the service=serverless-functions label.

Histogram metrics

Labels common for all histogram metrics:

Label	Value
resource_id	Function ID
version_id	Function version ID

Metric name Type, unit	Description Labels
`duration_ms_histogram` `IGAUGE`, milliseconds	Histogram of distribution of function run time. `bin` label: Histogram buckets.

Function performance metrics

Common labels for all function performance metrics:

Label	Value
resource_id	Function ID
version_id	Function version ID
resource_type	Resource type. The value is always `function`.

Metric name Type, unit	Description
`functions_avg_duration` `DGAUGE`, milliseconds	Average function execution time.
`functions_avg_init_duration` `DGAUGE`, milliseconds	Average function initialization time.
`functions_avg_memory` `DGAUGE`, bytes	Average memory used by the function.
`functions_avg_queue_duration` `DGAUGE`, milliseconds	Average execution wait time for a queued function.
`functions_errors` `DGAUGE`, errors	Number of errors when executing a function.
`functions_finished` `DGAUGE`, number	Number of completed function executions.
`functions_inflight` `DGAUGE`, invocations	Number of concurrent function invocations.
`functions_inits` `DGAUGE`, initializations	Number of function initializations.
`functions_max_duration` `DGAUGE`, milliseconds	Maximum function execution time.
`functions_max_init_duration` `DGAUGE`, milliseconds	Maximum function initialization time.
`functions_max_memory` `DGAUGE`, bytes	Maximum memory used by the function.
`functions_max_queue_duration` `DGAUGE`, milliseconds	Maximum execution wait time for a queued function.
`functions_min_duration` `DGAUGE`, milliseconds	Minimum function execution time.
`functions_min_init_duration` `DGAUGE`, milliseconds	Minimum function initialization time.
`functions_min_memory` `DGAUGE`, bytes	Minimum memory used by the function.
`functions_min_queue_duration` `DGAUGE`, milliseconds	Minimum execution wait time for a queued function.
`functions_started` `DGAUGE`, number	Number of function runs.
`functions_sum_duration` `DGAUGE`, milliseconds	Total function execution time.
`functions_sum_init_duration` `DGAUGE`, milliseconds	Total function initialization time.
`functions_sum_memory` `DGAUGE`, bytes	Total memory used by the function.
`functions_sum_queue_duration` `DGAUGE`, milliseconds	Total execution wait time for a queued function.
`functions_throttles` `DGAUGE`, number	Number of times the function got run restrictions.

Function metrics

Common labels for all function metrics:

Label	Value
function	Function ID
version	Function version ID

Metric name Type, unit	Description Labels
`serverless.functions.errors_per_second` `DGAUGE`, errors/s	Error frequency when processing function invocations.
`serverless.functions.execution_time_milliseconds` `IGAUGE`, invocations/ms	Histogram of function invocation frequency distribution by request processing time. Request processing time intervals are presented in the `bin` label.
`serverless.functions.finished_per_second` `DGAUGE`, invocations/s	Frequency of completing function invocation processing.
`serverless.functions.inflight` `DGAUGE`, invocations	Number of concurrent function invocations.
`serverless.functions.initializations_per_second` `DGAUGE`, initializations/s	Frequency of new function instance initializations.
`serverless.functions.started_per_second` `DGAUGE`, invocations/s	Function invocation frequency.
`serverless.functions.used_memory_bytes` `IGAUGE`, invocations/s	Histogram of function invocation frequency distribution by the amount of memory used in bytes. Intervals of the amount of memory used by the request are presented in the `bin` label.

Trigger metrics

Common labels for all trigger metrics:

Label	Value
trigger	Trigger ID
type	Trigger activation type: `incoming` or `request`.

Metric name Type, unit	Description Labels
`serverless.triggers.access_error_per_second` `DGAUGE`, errors/s	Access error frequency when processing function invocations.
`serverless.triggers.error_per_second` `DGAUGE`, errors/s	Error frequency when processing function invocations.
`serverless.triggers.execution_time_milliseconds` `IGAUGE`, invocations/ms	Histogram of function invocation frequency distribution by request processing time. Request processing time intervals are presented in the `bin` label.
`serverless.triggers.inflight` `DGAUGE`, invocations	Number of concurrent function invocations.
`serverless.triggers.read_events_per_second` `DGAUGE`, number/s	Frequency of events causing a trigger to fire.

DB connection metrics

Common labels for all DB connection metrics:

Label	Value
mdbproxy	DB connection ID

Metric name Type, unit	Description Labels
`serverless.mdbproxy.connections_inflight` `DGAUGE`, number	Number of simultaneous active DB connections.
`serverless.mdbproxy.query_execution_time_milliseconds` `IGAUGE`, number/ms	Histogram of DB query execution distribution. `bin` label: Histogram buckets.
