High load consumption - Artemis on Docker
Hello everyone
Recently we suffering from bad performance that cause our Artemis to be on
100% of cpu , load average is 12.8
Our Artemis is sitting on o e gcp vm based on Docker image, the version that
we running is 2.10
I really want need your help to understanding the problems, we've been
trying everything without success
Please advise
Thanks
Yossi

@tim for a first analysis is fine to use JVisualVM, but I recommend
async-profiler (or perf tools) because it shows GC activity, Kernel
activity (on the networking layer and disk) and, if they are using a native
SSL provider, the native methods cost of it (that often is huge). In
addition, JVisualVM suffer from the safepoint bias issue, like many other
profilers around, some reference here:

JVisualVM, which ships with the Oracle JDK (not sure about OpenJDK) is
another option. Be sure to use the CPU sampler, not the CPU profiler, if
you can't afford to add a significant load to the process (e.g. if this is
an operational host).

I mean not just GC logs but CPU profiling (async-profiler is a mixed
native-java profiler). Without something like that I cannot see how to help.

Hi thanks for the answers
Yes we did almost every memory analysis tools and we didn't find any
symptoms
It defentley something with the Artemis Broker...
We change the network Docker host implementation as well , insant of using
--proxy-docker we change it to --host network and still not luck
8bhope to get some answers we got lost here...

Re: High load consumption - Artemis on Docker

Have you tried profiling with async-profiler (or perf tools) where the CPU
time is spent? It could be either lack of memory on the heap (hence the GC
is doing much more work to free up memory continuously) or whatever
possible reason...
