profiler package provides performance profiling tools for Flux queries and operations.
profiler package includes the following options:
import "profiler" option profiler.enabledProfilers = ["query", "operator"]
List of Flux profilers to enable.
query profiler provides statistics about the execution of an entire Flux script.
When enabled, results returned by
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.
operator profiler output statistics about each operation in a query.
Operations executed in the storage tier
return as a single operation.
operator profile is enabled, results returned by
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
