Bernd Erk - Why favour Icinga over Nagios

Using The Icinga Linux Monitoring Wizard

Social recommendations and mentions

We have tracked the following product recommendations or mentions on various public social media platforms and blogs. They can help you see what people think about Icinga and what they use it for.
  • What do you use to visualize your topology?
    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: about 1 year 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: over 2 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 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. I was one of the two guys doing the setup for a company with multiple branch offices/ factories and during the time I was there it... Source: over 2 years ago
  • Is there any program that can alert you of a stalled Plex Server?
    Personally I run (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 2 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: almost 3 years ago
  • Anyone using LibreNMS in production?
    For alerting for Linux systems, I use Icinga with check_ssh and check_systemd (caveat: distributed primarily on PyPI) with Thruk as the single pane of glass front-end to per-datacenter installations of Icinga. Source: about 3 years ago
  • SSL error detection/expire bash script
    Collecting reports from multiple servers can turn into a fairly large to-do. That's why things like Icinga, Sensu, or a bunch of others exist - to continuously monitor and alert for a bunch of machines/services/etc. Source: about 3 years ago
  • Self-hosted map page for museum systems management?
    NagVis is a plugin for both Nagios and Icinga. They advertise geographic maps, but you can put building floorplans in it too. We used it with Nagios for years and it worked great. You should be able to add links to your ticketing system, and I expect you could find a way to put exhibit pics in it too. Source: over 3 years ago

Monit: An easy to use monitoring solution for Linux
Besides Nagios, Icinga and check_mk there are some other, more slimmer tools to monitor servers. Especially if you are a private person and you want to monitor your vServer, Raspberry Pi or whatever, you may want to use a smaller and easier monitoring solution than those big three. This article is about monit. Monit is one of these simple monitoring tool. But just because the configuration is more simple, that...
