Container metrics
Trigger metrics

This section describes Serverless Containers metrics delivered to Monitoring.

The metric name goes into the name label.

Container metrics

Common labels for all container metrics:

Label	Value
container	Container ID
revision	Container revision ID
service	Service label, always `serverless-containers`

Service metrics:

Name Type, units	Description Label
`serverless.containers.errors_per_second` `DGAUGE`, errors per second	Frequency of errors when processing container invocations.
`serverless.containers.execution_time_milliseconds` `IGAUGE`, invocations per millisecond	Histogram of the container invocation frequency distribution by request processing time. This metric features the `bin` label containing histogram buckets.
`serverless.containers.execution_time_milliseconds_count` `COUNTER`, invocations	Total number of container invocations included in the request processing time histogram.
`serverless.containers.execution_time_milliseconds_sum` `COUNTER`, milliseconds	Total processing time of all container invocations included in the histogram.
`serverless.containers.finished_per_second` `DGAUGE`, invocations per second	Frequency of completing container invocation processing.
`serverless.containers.inflight` `DGAUGE`, invocations	Number of concurrent container invocations.
`serverless.containers.started_per_second` `DGAUGE`, invocations per second	Frequency of container invocations.
`serverless.containers.used_memory_bytes` `IGAUGE`, bytes	Histogram of the container invocation frequency distribution by RAM used. This metric features the `bin` label containing histogram buckets.
`serverless.containers.used_memory_bytes_count` `COUNTER`, invocations	Total number of container invocations included in the RAM usage histogram.
`serverless.containers.used_memory_bytes_sum` `COUNTER`, bytes	Total RAM used by all container invocations included in the histogram.

Trigger metrics

Labels shared by all trigger metrics:

Label	Value
trigger	Trigger ID
type	Entity type.
service	Service label, always `serverless-functions`

Metric name Type, unit	Entity type.	Description Labels
`serverless.triggers.access_error_per_second` `DGAUGE`, errors per second	`request`: Container invocations. `message_queue`: Accesses to Yandex Message Queue. `dlq`: Accesses the dead letter queue.	Access error frequency when processing container invocations.
`serverless.triggers.error_per_second` `DGAUGE`, errors per second	`request`: Container invocations. `message_queue`: Accesses to Yandex Message Queue. `dlq`: Accesses the dead letter queue.	Frequency of errors when processing container invocations.
`serverless.triggers.execution_time_milliseconds` `IGAUGE`, invocations per millisecond	`request`: Container invocations.	Histogram of container invocation rate distribution by request processing time. Request processing intervals are stored in the `bin` label.
`serverless.triggers.inflight` `DGAUGE`, invocations	`request`: Container invocations.	Number of concurrent container invocations.
`serverless.triggers.read_events_per_second` `DGAUGE`, units per second	`incoming`: Events causing any trigger to fire except for a trigger for Yandex Message Queue. `message_queue`: Events causing a trigger for Yandex Message Queue to fire.	Frequency of events causing a trigger to fire.
