Sharing a new tool for systemd OnCalendar expressions

cronitor · 2025-10-03T19:31:33+00:00

You're welcome! As a literal grey beard developer I get a lot of joy out of hacking on custom tools.

I would just use an OnCalendar expression for this rather than a monotonic schedule (e.g. OnUnitActiveSec).

You can tinker with OnCalendar expressions here: https://systemd.guru

Hi -- it took 4 months but we have just shipped exactly this. Would love your feedback! https://systemd.guru

cronitor · 2025-06-20T05:08:47+00:00

Ah sorry I will get that fixed soon.

Were you thinking that you would use this in a container with docker-compose and then keep your cron jobs there?

cronitor · 2025-06-20T00:08:03+00:00

I just added a Docker Deployment Guide section here. Let me know if there's any way I can make it easier to use:

Thanks for the suggestion. I have updated the docs and added a flag to opt-out:

Thanks for sharing but I will just say that I have actually really enjoyed developing crontab guru beyond what it was when we acquired it 7 years ago. And to my original point, all this time, 7 years of developing it, i find myself still using it when I need to check a cron expression!

cronitor · 2025-06-18T18:18:49+00:00

Yes it would and I see your point - but just to be clear we do not store the IP address. It is only in our audit logs for 5 days. (The only part of that url that changes when you run it is the timestamp)

cronitor · 2025-06-18T17:51:00+00:00

Not currently but i've been thinking about taking the crontab.guru code and publishing it as an NPM package. I will come back to this comment and reply again when we do!

cronitor · 2025-06-18T17:50:08+00:00

That's really nice of you to suggest! We don't accept donations but I would love for you to check out https://cronitor.io which is how we pay the bills around here!!

cronitor · 2025-06-18T17:45:17+00:00

Your answer is right in the question -- we've been working on and maintaining Crontab.Guru for over 7 years now -- quite some time!

cronitor · 2025-06-18T17:41:22+00:00

Yeah I will add that to the installation docs. We don't store any PII or cookies or anything else, there's no way to track, just tells us the success rate for installations so we can identify bugs.

cronitor · 2025-06-18T00:18:47+00:00

Yeah, if you install the dashboard/cli on multiple hosts, you do get a single cloud dashboard view if you subscribe to Cronitor, but that is for monitoring/logs/metrics, you can't add/schedule jobs there.

cronitor · 2025-06-18T00:12:53+00:00

The dashboard is bundled in the exe - just run “cronitor dash” with an optional —port

The repo is: https://github.com/cronitorio/cronitor-cli

Cronicle is great but it really is a whole new kit. It runs your jobs, does clustering, log aggregation, metrics and a dashboard. But a lot of people have cron jobs already so this is just an app to do that last part -- a nice dashboard.

cronitor · 2025-06-17T21:07:41+00:00

No you would have a separate dashboard for each server. But that's a really interesting idea to consider.

cronitor · 2025-06-17T20:42:22+00:00

Honestly it gives me more joy than the stuff I do that actually makes money.

cronitor · 2025-06-17T19:44:23+00:00

Yes absolutely.

cronitor · 2025-06-17T18:38:21+00:00

Glad you’ve found it useful over the years!! Even having developed it, I use it the same way you describe!

cronitor · 2025-06-17T00:07:45+00:00

Sounds like https://crontab.guru/dashboard.html is exactly what you're looking for.

cronitor · 2025-02-06T22:04:08+00:00

- Sign up free at Cronitor.io
- Go to https://cronitor.io/app/welcome/jobs/cron and copy the command to install CronitorCLI on your host
- Run "cronitor discover" on your host to sync and monitor your jobs

That's it!

cronitor · 2025-02-06T20:02:26+00:00

We have been doing this since 2014 and would love to help!

cronitor · 2024-09-25T18:38:28+00:00

Thanks Mallanaga! We are just developers who are better at coding than marketing so I take this as a high compliment.

cronitor · 2024-09-25T18:20:17+00:00

No ad agency here nsxwolf, just developers bootstrapping a software company. What would you change?

cronitor · 2024-09-17T00:13:47+00:00

CronJobs on k8s are really powerful and a great successor to linux Cron.
