> UptimeRobot and Hetrixtools are good starters with generous free tier Are there any open source status pages/monitor programs that have build-in checks for HTTPS, DNS records (ipv4/6), arbitrary port checks, etc? I'd rather just setup a status page/alert app on a $5 minimal DO/Vultr node and self-host/support/contribute to a FOSS program than use a commercial provider.

If you want email or text message alerts I would assume that's a complicated enough system you would want uptime alerts on it, and so on recursively ad infinitum.

  If you can set up nagios (which one would probably consider an interesting evening challenge if you were already willing to go for your own monitoring droplet) setting up pushover or amazon sns (for sms) should be easy enough.

    I would try to set up a completely open source monitoring setup just for fun, but once I'm paying for SNS I personally would rather just pay epsilon more and buy/rent the whole system. I get that may just be personal taste. I absolutely don't trust myself to run my own highly-reliable mailserver to send status alerts.

      Just send them locally and pull them with IMAP onto your phone.

        I didn't even know that was possible. Thanks for teaching me something new. It's always nice to learn I need less SAAS magic than I thought.

    FWIW, a lot of cellular providers have an email gateway for delivering SMS messages. There's also paid SMS gateways, and options for providing arbitrary push notifications to smartphones.

      I'm pretty sure the free email gateways have no posted SLA. Plus, that requires a reliable email server, which would also need its own monitoring.

        This was a few (3) years past, but they accepted root@localhost sendmail messages just fine in most cases, and delivered alerts within a minute or two of sending. We didn't rely on this long term, but it was a "good enough" first pass. I'd probably recommend using one of the gateways (or a more fully-featured service like Pagerduty) for more serious businesses, but for personal use (or where an outage detected the next day isn't crippling), it's remarkably useful.

You need to host across several nodes in different geographic locations and data centers to resist network splits. Then you need some way to slowly roll out upgrades to your monitoring platform over time.

  I'm just talking about my personal infrastructure. If I host my crap in Vultr or Linode, I should be able to buy one cheap node on another provider just to run a simple status app: something with celary or sidekiq jobs to check my other stuff and intervals and generate a page with some red/yellow/green dots.
  - vorpalhex 7y ago
    How do you know if the monitoring node goes down at the same time as the other servers? Remember that Linode/Vultr/etc don't run their own datacenters, they share datacenters and sometimes downtime events can exist outside of datacenters.

Here is a good list: https://github.com/n1trux/awesome-sysadmin#monitoring https://github.com/n1trux/awesome-sysadmin#monitoring Maybe one fits what you are looking for.

I wrote a scalable system for this: https://github.com/skx/overseer/ https://github.com/skx/overseer/ Handles SSL-checks, DNS-checks, SMTP-checks, & etc. Runs a thousand-checks every two minutes for me, give or take. Pluggable output via a redis-queue.
