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: 12 months 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 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 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. 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 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 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: over 2 years ago
