New Monitor, UI Feature

🔖 Feature description

To monitore cron, it's easier to send OK/NOK with curl (like healthcheck.io) or if cron don't execute after specific time it raise an alert.

I see push monitore and I think it can have a little improvement : set Heartbeat interval in second or cron execution format.

For exemple I want to monitore a cron who execute each monday at 3AM, I can define 604800 in interval, or define 0 3 * * 1 in interface to monitore the cron

✔️ Solution

Add in push monitor a way to select interval or cron execution time format.

❓ Alternatives

Healtcheck.io can work (it work) but multiplying the tools can be a bit of a headache

I don't think this will be a thing for uptime kuma. Its more for web things like websites, dns records and so one but not for cronjobs.

[Eidenz]

I think this is a great idea. I don't see why uptime-kuma couldn't be used to monitor cronjobs, it would do the job just fine.

If there are push monitors, why not time range push.

[Seele0oO]

That's what I think too. The time interval alone is not sufficient for monitoring the status of the task.

[HujinoKun]

It would be great to have an api that would allow to send POSTs to know if our cronjob was successful or not.

A bit like betteruptime does

I think it's a good feature for Kuma, web services often have cron jobs hidden they rely on.

I'm also interested in this functionality, similiar to what cronitor does: https://cronitor.io/cron-job-monitoring

I the feature itself would be interesting, I'm willing to create a PR for that

Changing the monitor sheduler is a lot of work.
Current plan is here if you want to contribute to this PR (via targeting the queue instead of the master branch):
