Show HN: Sigabrt.dev – cronjob monitor with an SSH TUI

44815162342 1 day ago 9 commentsRead Article on sigabrt.dev

Hello HN. I built this mostly to monitor the things I host myself. I know it's nothing too exciting.

Anyway, the TL;DR is: Create an endpoint, and if your script/cronjob fails to regularly ping it, you get notified (by email or ntfy). E.g.:

    0 * * * * ./script.sh && curl -fsS https://sigabrt.dev/pulse/<id>/beat

It also has an SSH TUI which is currently experimental and read-only, mostly because I'm not sure whether it is actually useful or just a gimmick :):

    ssh sigabrt.dev

To use it, simply add your SSH public key in your account settings.

Yes, there are services like this already, and this is minimalistic by comparison. Feedback is welcome.

I'm myself very happy with https://healthchecks.io/ for this purpose.

I'll never understand commenting to show HNs with a link to competing products.

If it has context I appreciate them because it helps me make better informed decisions. Why not? HN isn't an editorials page exclusive for posters (except YC slop lol)

Why?

Because OP is trying to promote his project and get feedback, and you post about a competing product, to me the message is: don't look at the project OP wants you to check out, I've been using this instead and and it's amazing!

Who cares what you're using, I see show HN posts to be about OP's project, seems like a dick move to me to diverge attention to some other project. I just don't understand the motivation

If you need/want a dashboard it's kinda cool. There's a lot of other options that will do something similar, but not via SSH. Crontab can email you directly, no need for a service.

You could also just use systemd timers and do: systemctl --failed -t service

You need some sort of external monitor for a missed pulse style alert. Personally I do something similar by collecting a "last success" metric with Prometheus and alerting on it with Grafana if the value is too far in the past. The local system cannot reliably alert if your job does not fail into the alert path or the system is just down.

I can see something like this being a great intermediate option to a full monitoring and alerting stack.

You are missing the biggest value offering here - service such as the one linked here (or healthchecks io that I personally use) will let you know that signal didn't arrive even when other things on your end failed (e.g. cron having a hard time sending failure email due to incorrect smtp credentials). I use those kind of healthchecks literally for everything, especially for backups - they saved my ass many times over.
