  • Ask HN: What do you monitor on your servers?
    Or Checkmk [1], which is coming from Nagios and brings thousands of plugins for nearly every hardware and service you can think of.. [1] https://checkmk.com/. - Source: Hacker News / 9 months ago
  • Monitoring solution
    CheckMK https://checkmk.com. You can spin this up in a docker container. Source: almost 2 years ago
  • "All in one monitoring solution"?
    I use CheckMK to do all of this and more, except nutanix. But checkmk also can Monitor nutanix via the "Nutanix Prism" special agent Integration. Source: almost 2 years ago
  • Is there an alternative to BI Tools?
    BI machine and NVR report to CheckMK Raw host so it's easy to see historic stats. Source: almost 2 years ago
  • Uptime Monitor
    I’m using https://checkmk.com/ to monitor stuff and it seems to work great. Lots of built in features and functions and if they don’t have what you need you can also create custom scripts to check and report on anything you can dream up. Runs great in docker (I’m using portainer but will run fine in plain old docker). Source: almost 2 years ago

    Two manually updated svg maps on nagvis that integrate with our icinga checks, one for the transport system nodes and one for the routers. Source: almost 2 years ago
  • SSLPing permanently goes out of service
    Might be a bit of an overkill if you just want to check the certificates, but I'm using Icinga (formerly known as Nagios) to keep track of all of the systems - including webpage certificates. Source: about 3 years ago
  • What "legacy" software are you still forced to use in 2022 that you wish would die?
    Some of it can be migrated rather easily to Icinga https://icinga.com/. Icinga forked from Nagios many years ago, they rewrote the engine and have done a nice WebUI. It is able to support e.g. Business branches using "satellites" that act as proxy to the main server/ server cluster.

  • Is there any program that can alert you of a stalled Plex Server?
    Personally I run https://icinga.com/ (to all my services, including Plex) and it polls every 5sec and after 5 fails in a row it sends me an email. Source: over 3 years ago
  • Linux is dead, long-live Docker monoculture
    Fast forward 12 years and I have Icinga2 collectors in each datacenter using check_by_ssh to run check_systemd, all front-ended by Thruk. The TIG stack is something on my list of things to look into at some point, but with Dynatrace available to do all the fancy application monitoring, there's no rush. Source: over 3 years ago
