Flow
Flow metrics measure the execution of flow classes provided by the CorDapp Corda Distributed Application. A Java (or any JVM targeting language) application built using the Corda build toolchain and CorDapp API to solve some problem that is best solved in a decentralized manner. , providing an indication of the performance and health of the flow engine Corda uses to execute these flows.
| Metric | Type | Tags | Description |
|---|---|---|---|
corda_flow_run_time_seconds | Timer |
| The time it took for a flow to complete successfully or to produce an error. |
corda_flow_fiber_serialization_time_seconds | Timer |
| The time it took to serialize a flow fiber. |
corda_flow_fiber_deserialization_time_seconds | Timer |
| The time it took to serialize a flow fiber. |
corda_flow_start_lag_seconds | Timer |
| The lag between flow start event, the REST API, and the flow processor. |
corda_flow_execution_time_seconds | Timer |
| The time it took to execute the flow (excluding any start lag). |
corda_flow_event_lag_seconds | Timer |
| The lag between flow event publication and processing. |
corda_flow_event_pipeline_execution_time_seconds | Timer |
| The time it took to execute the pipeline for given flows and flow event types. |
corda_flow_event_fiber_execution_time_seconds | Timer |
| The time it took to execute the fiber for a single suspension point. |
corda_flow_pipeline_execution_time_seconds | Timer |
| The total time that a flow spent processing in the pipeline, rather than queued (includes fiber execution time.) |
corda_flow_fiber_execution_time_seconds | Timer |
| The total time a flow spent executing user code in the fiber. |
corda_flow_suspension_wait_time_seconds | Timer |
| The time a flow spent waiting to awake from a suspension. |
corda_flow_event_suspension_wait_time_seconds | Timer |
| The time a flow spent waiting to awake from a single suspension, broken down by action. |
corda_flow_scheduled_wakeup_count | Counter | None | The number of times a scheduled wakeup is published for flows. |
