Metrics Reference

Overview

Varax Monitor exports Prometheus metrics for every CronJob in your cluster. All metrics are labeled with namespace and cronjob for easy filtering and aggregation.

Metrics

Metric	Type	Labels	Description
cronjob_last_execution_status	Gauge	namespace, cronjob	Last execution result (1=success, 0=failure)
cronjob_last_execution_duration_seconds	Gauge	namespace, cronjob	Duration of last execution in seconds
cronjob_execution_total	Counter	namespace, cronjob, status	Total executions (status: success or failure)
cronjob_missed_schedules_total	Counter	namespace, cronjob	Count of missed scheduled executions
cronjob_next_schedule_time	Gauge	namespace, cronjob	Unix timestamp of next expected run
cronjob_is_suspended	Gauge	namespace, cronjob	Whether the CronJob is suspended (1=yes, 0=no)

Labels

Label	Description
namespace	Kubernetes namespace of the CronJob
cronjob	Name of the CronJob resource
status	Execution result — success or failure (only on cronjob_execution_total)

Example PromQL Queries

Currently failing CronJobs:

cronjob_last_execution_status == 0

Failure rate over the last 24 hours:

sum(increase(cronjob_execution_total{status="failure"}[24h])) by (cronjob, namespace)

Top 5 slowest CronJobs:

topk(5, cronjob_last_execution_duration_seconds)

CronJobs that missed schedules in the last hour:

increase(cronjob_missed_schedules_total[1h]) > 0

All suspended CronJobs:

cronjob_is_suspended == 1

Success rate per CronJob:

sum(rate(cronjob_execution_total{status="success"}[7d])) by (cronjob)
/
sum(rate(cronjob_execution_total[7d])) by (cronjob)

Relationship to kube-state-metrics

Varax Monitor complements kube-state-metrics — it doesn’t replace it. kube-state-metrics provides general Kubernetes object state (pod counts, deployment replicas, etc.). Varax Monitor adds CronJob-specific execution tracking that kube-state-metrics doesn’t cover: execution duration, missed schedules, and per-run success/failure tracking.

You can run both side by side with no conflicts.
