  • Show HN: I built a self-hosted status page and monitoring tool for my projects
    Hey mate, I'm using for heartbeat monitoring my crons. It's been working flawlessly for quite some time now. The UI is super clean and easy to navigate. It's also free up to 20 monitored jobs. Note - I'm not in any way related to that project. - Source: Hacker News / about 2 months ago
  • Webhooks suck, but here are alternatives
    In fact, your platform ( is a prime example of where running customer wasm would be really excellent. Instead of sending webhooks out to customer configured URLs, you could run a Wasm environment to execute customer code. Off hand, a good use case here is to do further inspection of the event before it gets sent off to some other system - maybe there are cases where you send... - Source: Hacker News / 4 months ago

  • Show HN: OnlineOrNot – Cron Job Monitoring
    Is there anything different from --- a service I've been using for free for a couple years now? - Source: Hacker News / 9 months ago
  • Prioritize IPv4 over IPv6 in dual stack
    Because of this block on the router, and the fact that IPv6 connections are by default preferred over IPv4, many things on the system now cannot access the internet. The only things that can access the internet are for accessing servers that ONLY support IPv4 like my mail.smpt2go or my uptime monitoring scripts for Source: 9 months ago
  • Ask HN: How do you monitor your systemd services?
    If you are ok with a Saas and if it's just scheduled jobs that you are monitoring, there are a number of monitoring tools where you tell when job completes (with a http request) and a missing ping (after a grace period) means that it failed. I think may have been the original service for this. has a fairly generous free tier that I use now. There are others that... - Source: Hacker News / 11 months ago
  • Show HN: Peeng – like Pingdom, but the other way around and simpler
    A service in a very similar vein is - which also provides a nice perspective on how low-effort the setup for a service with a substantial amount of users can be.

  • setup
    I don't run healthchecks for containers themselves, but for the server as a whole. I use Uptime Kuma in a docker container, setting it to ping to a configured check remotely on every 15 minutes. That way if my server loses internet or something major goes wrong, I'll get an email. But I 'm the only one that uses my services besides Plex, so if something goes wrong with them individually, it isn't a... Source: about 1 year ago

  • Second WAN just for notifications
    I recommend using an external service like and send heartbeats from Zabbix. If x amount of heartbeats fail, then you get an alert of your choice. This way you also get notified if Zabbix stops working for any other reason. Source: about 1 year ago

  • Since sending an email in Task Scheduler is deprecated what is your solution? Looking for simple and lightweight. (free,paid, or self-hosted) and have your job(s) curl the URL for a healthcheck. It can trigger the email when it gets the request or a period of time after it doesn't get the request in a specified timeframe. This lets you send alerts that it worked, and alerts when a job fails to report in so you don't miss failing jobs. Source: about 1 year ago
  • Is there any admin ability to email users?
    Healthchecks is probably what you’re looking for. Run a timed script on the OS of your liking, when you lose power the script stops and healthchecks send you an email. You can have 20 monitors for free. Https:// Source: about 1 year ago
