Controller Metrics

The Argo Rollouts controller publishes the following prometheus metrics about Argo Rollout objects.

Name Description
rollout_created_time Creation time in unix timestamp for an rollout.
rollout_info Information about rollout.
rollout_phase Information on the state of the rollout.
rollout_reconcile Rollout reconciliation performance.
rollout_reconcile_error Error occurring during the rollout.
experiment_created_time Creation time in unix timestamp for an experiment.
experiment_info Information about Experiment.
experiment_phase Information on the state of the experiment.
experiment_reconcile Experiments reconciliation performance.
experiment_reconcile_error Error occurring during the experiment.
analysis_run_created_time Creation time in unix timestamp for an Analysis Run.
analysis_run_info Information about analysis run.
analysis_run_metric_phase Information on the duration of a specific metric in the Analysis Run.
analysis_run_metric_type Information on the type of a specific metric in the Analysis Runs.
analysis_run_phase Information on the state of the Analysis Run.
analysis_run_reconcile Analysis Run reconciliation performance.
analysis_run_reconcile_error Error occurring during the analysis run.

The controller also publishes the following Prometheus metrics to describe the controller health.

Name Description
controller_clientset_k8s_request_total Number of kubernetes requests executed during application reconciliation.
workqueue_adds_total Total number of adds handled by workqueue
workqueue_depth Current depth of workqueue
workqueue_queue_duration_seconds How long in seconds an item stays in workqueue before being requested.
workqueue_work_duration_seconds How long in seconds processing an item from workqueue takes.
workqueue_unfinished_work_seconds How many seconds of work has done that is in progress and hasn't been observed by work_duration. Large values indicate stuck threads. One can deduce the number of stuck threads by observing the rate at which this increases.
workqueue_longest_running_processor_seconds How many seconds has the longest running processor for workqueue been running
workqueue_retries_total Total number of retries handled by workqueue

In additional, the Argo Rollouts controllers offers metrics on CPU, memory and file descriptor usage as well as the process start time and current Go processes including memory stats.
