Agent Environment

agent 7.63.3

Describe what happened:

I setup an alert based on the kubernetes_state.cronjob.on_schedule_check to detect missed Cronjob schedules.

Some K8s cronjobs are setup with the Cronjob spec timeZone parameter.

Example:

  schedule: 30 8 * * 1-6
  timeZone: Europe/Paris

With this configuration, the monitor based on this check is in error from 10:30 (UTC+2) even if the job executed at exactly 8:30 (UTC+2)

Describe what you expected:

No alert

Steps to reproduce the issue:

• Create a cronjob with a schedule based on a non UTC timeZone
• Create a monitor based on the kubernetes_state.cronjob.on_schedule_check
• Wait for job scheduled execution time

Additional environment details (Operating System, Cloud provider, etc):

EKS

Analysis:

kube_cronjob_next_schedule_time does not take Cronjob spec timeZone parameter into account.
