1-117: Telemetry metrics are properly defined and initializedThe metrics are correctly set up using OpenTelemetry conventions. The units, descriptions, and bucket boundaries are appropriately specified for each metric.
pkg/jobstore/boltdb/store.go (8)
164-177: Well-implementedmetricRecordermethodThe
metricRecorderfunction is effectively designed to initialize metric recorders with the correct attributes, enhancing observability for database operations.
191-196: Enhanced observability inGetJobmethodThe integration of telemetry metrics into the
GetJobmethod effectively improves observability, allowing for detailed monitoring of job retrieval operations.
Line range hint
258-277: Proper metric recording ingetExecutionfunctionThe additions of metric recordings, such as latency measurements and data counters, in the
getExecutionfunction are correctly implemented to monitor execution retrieval performance.
355-364: Efficient metric logging within loopsMetrics within loops, like in the execution fetching loop, are correctly placed to account for each iteration, ensuring accurate data aggregation.
660-666: Consistent attribute usage in telemetryThe attributes added to the metric recorder in
GetExecutionsare consistent and provide valuable context for the operations being monitored.
919-928: Validation and normalization inCreateJobThe job creation process includes necessary validation and normalization steps before storing the job, adhering to best practices.
1002-1007: Correct handling of job deletion inDeleteJobThe
DeleteJobmethod appropriately records metrics and handles the deletion process, including index updates.
1061-1065: Accurate state transition metrics inUpdateJobStateMetrics capturing the state transitions in
UpdateJobStateprovide detailed insights into job state changes, enhancing observability.

Avoid using defer with recorder.Latency; measure latency explicitly
Using defer with recorder.Latency may not accurately measure the latency of specific operation segments because defer delays execution until the surrounding function returns. This can result in capturing the total execution time of the function rather than the intended code block, leading to misleading metrics.
Apply the following changes to measure latency explicitly:
// In reifyJobID function (lines 229-230)
- defer recorder.Latency(ctx, jobstore.OperationPartDuration, jobstore.AttrOperationPartReifyID)
+ startTime := time.Now()
// ... code for reifyJobID ...
+ recorder.Latency(ctx, jobstore.OperationPartDuration, jobstore.AttrOperationPartReifyID, time.Since(startTime))
// In getJobsIncludeTags function (line 537)
- defer recorder.Latency(ctx, jobstore.OperationPartDuration, "filter_include_tags")
+ startTime := time.Now()
// ... code for getJobsIncludeTags ...
+ recorder.Latency(ctx, jobstore.OperationPartDuration, "filter_include_tags", time.Since(startTime))
// In getJobsExcludeTags function (line 567)
- defer recorder.Latency(ctx, jobstore.OperationPartDuration, "filter_exclude_tags")
+ startTime := time.Now()
// ... code for getJobsExcludeTags ...
+ recorder.Latency(ctx, jobstore.OperationPartDuration, "filter_exclude_tags", time.Since(startTime))
// In getJobsBuildList function (lines 587-588)
- defer recorder.Latency(ctx, jobstore.OperationPartDuration, "build_list")
+ startTime := time.Now()
// ... code for getJobsBuildList ...
+ recorder.Latency(ctx, jobstore.OperationPartDuration, "build_list", time.Since(startTime))
// In getJobHistory function (line 828)
- defer recorder.Latency(ctx, jobstore.OperationPartDuration, "determine_pagination")
+ startTime := time.Now()
// ... code for pagination determination ...
+ recorder.Latency(ctx, jobstore.OperationPartDuration, "determine_pagination", time.Since(startTime))Also applies to: 537-537, 567-567, 587-588, 828-828
