This section describes Serverless Integrations metrics delivered to Monitoring.

The metric name goes into the name label.

Yandex Workflows metrics

All Workflows metrics share the workflow label, which is the workflow ID.

Metric name Type, units	Description Labels
`step_completed_per_second` `DGAUGE`, steps per second	Number of completed steps per second. This metric features the `step` label containing the step name.
`step_failed_per_second` `DGAUGE`, steps per second	Number of failed steps per second. Labels: `step`: Step name `error_code`: Error code.
`step_inflight_count` `DGAUGE`, steps	Number of steps currently in progress. This metric features the `step` label containing the step name.
`step_started_per_second` `DGAUGE`, steps/s	Number of started steps per second. This metric features the `step` label containing the step name.
`step_time_milliseconds` `DGAUGE`, milliseconds	Step execution time. Labels: `bin`: Histogram buckets. `step`: Step name
`step_time_milliseconds_count` `DGAUGE`, number of steps	Total number of step time measurements. This metric features the `step` label containing the step name.
`step_time_milliseconds_sum` `DGAUGE`, milliseconds	Total execution time for all steps. This metric features the `step` label containing the step name.
`workflow_completed_per_second` `DGAUGE`, workflows per second	Number of completed workflows per second
`workflow_failed_per_second` `DGAUGE`, workflows per second	Number of failed workflows per second. This metric features the `error_code` label containing the error code.
`workflow_inflight_count` `DGAUGE`, workflows	Number of workflows currently in progress
`workflow_scheduled_per_second` `DGAUGE`, workflows per second	Number of scheduled workflows per second
`workflow_started_per_second` `DGAUGE`, workflows per second	Number of started workflows per second
`workflow_time_milliseconds` `DGAUGE`, milliseconds	Execution time per workflow. This metric features the `bin` label containing histogram buckets.
`workflow_time_milliseconds_count` `DGAUGE`, count	Total number of workflow time measurements.
`workflow_time_milliseconds_sum` `DGAUGE`, milliseconds	Total execution time for all workflows.

Yandex EventRouter metrics

All EventRouter metrics share the bus label, which is the bus ID.

Bus metrics

Metric name Type, units	Description Labels
`serverless_eventrouter_bus_put_event_per_second` `DGAUGE`, messages per second	Frequency of messages sent using the EventService/Put gRPC API call.
`serverless_eventrouter_bus_sent_error_per_second` `DGAUGE`, errors per second	Frequency of bus errors. Labels: `code`: Error code. The possible values are: `EVENTROUTER_BUS_SEND_ERROR` `EVENTROUTER_EVENT_SIZE_EXCEEDED` `source`: Source
`serverless_eventrouter_put_event_latency_milliseconds` `DGAUGE`, milliseconds	Time from receiving a message sent using the EventService/Put gRPC API call until it is written to the bus.

Connector metrics

All connector metrics share the connector label, which is the connector ID.

Metric name Type, units	Description
`serverless_eventrouter_connector_access_error_per_second` `DGAUGE`, errors per second	Frequency of connector resource access errors
`serverless_eventrouter_connector_error_per_second` `DGAUGE`, errors per second	Frequency of connector errors
`serverless_eventrouter_connector_event_per_second` `DGAUGE`, events per second	Connector's event read rate
`serverless_eventrouter_connector_event_size_exceeded_per_second` `DGAUGE`, errors per second	Frequency of maximum size exceeded errors in messages received by the connector

Rule metrics

All rule metrics share the following labels:

Label	Value
matched	Matching the filter conditions
rule	Rule ID

Metric name Type, units	Description
`serverless_eventrouter_rule_event_per_second` `DGAUGE`, events per second	Rule processing rate

Target metrics

All target metrics share the following labels:

Label	Value
rule	Rule ID
type	Target type

Metric name Type, units	Description
`serverless_eventrouter_event_delivery_time_milliseconds` `DGAUGE`, milliseconds	Time from event receipt by the connector to its delivery to the target
`serverless_eventrouter_target_access_error_per_second` `DGAUGE`, errors per second	Frequency of access errors in the target
`serverless_eventrouter_target_error_per_second` `DGAUGE`, errors per second	Frequency of target errors
`serverless_eventrouter_target_event_size_exceeded_per_second` `DGAUGE`, errors per second	Frequency of maximum size exceeded errors in messages received by the target
`serverless_eventrouter_target_execution_time_milliseconds` `DGAUGE`, milliseconds	Message processing time
`serverless_eventrouter_target_inflight` `DGAUGE`, count	Number of targets that are currently busy
`serverless_eventrouter_target_retry_per_second` `DGAUGE`, sends per second	Frequency of retry attempts to send messages to the target
`serverless_eventrouter_target_throttled_per_second` `DGAUGE`, messages per second	Frequency of messages not processed due to exceeding a quota or limit
