profiler package

The profiler package provides performance profiling tools for Flux queries and operations.

Profile results are returned as an extra result in the response named according to the profiles which are enabled.


option profiler.enabledProfilers = [""]


enabledProfilers is a list of profilers to enable during execution.

Available profilers


Provides statistics about the execution of an entire Flux script. When enabled, results include a table with the following columns:

  • TotalDuration: total query duration in nanoseconds.
  • CompileDuration: number of nanoseconds spent compiling the query.
  • QueueDuration: number of nanoseconds spent queueing.
  • RequeueDuration: number fo nanoseconds spent requeueing.
  • PlanDuration: number of nanoseconds spent planning the query.
  • ExecuteDuration: number of nanoseconds spent executing the query.
  • Concurrency: number of goroutines allocated to process the query.
  • MaxAllocated: maximum number of bytes the query allocated.
  • TotalAllocated: total number of bytes the query allocated (includes memory that was freed and then used again).
  • RuntimeErrors: error messages returned during query execution.
  • flux/query-plan: Flux query plan.
  • influxdb/scanned-values: value scanned by InfluxDB.
  • influxdb/scanned-bytes: number of bytes scanned by InfluxDB.


The operator profiler output statistics about each operation in a query. Operations executed in the storage tier return as a single operation. When the operator profile is enabled, results include a table with a row for each operation and the following columns:

  • Type: operation type
  • Label: operation name
  • Count: total number of times the operation executed
  • MinDuration: minimum duration of the operation in nanoseconds
  • MaxDuration: maximum duration of the operation in nanoseconds
  • DurationSum: total duration of all operation executions in nanoseconds
  • MeanDuration: average duration of all operation executions in nanoseconds
