I've been using Nagios Core for our monitoring needs for as long as I can remember. We've got a pretty basic setup monitoring both Linux and Windows servers (CPU, RAM, disk etc). When googling around for Nagios it feels like everything you find was posted like 4 years ago. The latest Nagios Core release was sometime in 2020 (nothing really wierd about that through), looking at the Nagios Exchange it's hard to find "up to date" stuff.
The reason for this might be that there is no reason to update it, I don't know. However it feels pretty wierd and outdated. Don't get me wrong, I love Nagios and it does what we need it to do but I'm just curious to what other options are out there.
Are there other open source alternatives that are better? Or have comercial products like Nagios XI, OP5, SolarWinds etc. taken over?
Have I been sleeping under a rock for omegle.2yu.co the last couple of years and missed something obvious? What are you omeglz echat using to monitor your environment?
