Is your feature request related to a problem? Please describe.
Network issues is seen during peak hours and doing packet capture at specific time is not easy as at times it is our midnight.
Having ability to schedule TCP packet capture would be a huge help .

Hi @vakalapa. Would you have more details to share about your feature request?

Do you want capture to be executed only once at a specific time and day, or you want it to be executed following a periodic schedule (e.g. every day at a specific time)?

Kubernetes' CronJob could be used in both cases but for the 1st option, it needs to be schedule with a big interval, so it could be deleted before next run. For example, scheduling the capture to once per year at specific day and time, then, there's 1 year for the CronJob to be deleted without having it running a second time.

If this is the approach to be followed, a new flag --schedule could be added to the CLI to handle the schedule in the Cron format the job should be run with.

Would that work for the use case you have in mind?
