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 1 year ago
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
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
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
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
If you're curious, attach VisualVM and watch the RAM usage graph. You'll notice that Java performs garbage collections long before reaching allocating the maximum amount of RAM allocated, and you can't even feel any performance issue in-game. Source: 11 months ago
Hangs and deadlocks are significantly harder to debug. A first step is taking a thread dump so you can see what each thread in the JVM is currently trying to do. I like VisualVM for this, you can also use the command-line tools jps -l (to list all Java PIDs) and jstack for taking a thread dump. Source: 12 months ago
The Java VisualVM project is an advanced dashboard for Memory and CPU monitoring. It features advanced resource visualization, as well as process and thread utilization. - Source: dev.to / 12 months ago
This sounds like a server thread freeze/deadlock/crash or something. I think I would start debugging this using a tool like VisualVM; attach it to the game, wait for the hang, take a thread dump, and check what the server thread is up to. Source: about 1 year ago
Just wanted to chip in to say that /u/UtilFunction is correct. The proper way to measure memory consumption of any Java application independent of which garbage collector is used is to perform a heap dump (which automatically forces a complete garbage collection). I like to use VisualVM for that. Source: about 1 year ago
