XORMON server high CPU utilization

LeonK

Hi, we are using XorMon 1.8.14 and are experiencing performance problems on the XorMon server.

Sizing is 4 CPU and 16GB RAM.

All CPU cores are sitting at 100% utilization permanently. (load average is 17.75 11.03 10.62)

Top CPU% jobs are always postgres jobs with a command lines like this:

• postgres: 16/main: postgres xormon 127.0.0.1(xxx) DELETE
• postgres: 16/main: postgres xormon 127.0.0.1(xxx) idle

We suspect that the issue is related to IBM i os agent monitoring, we got ~250 IBM i LPARs sending performance data to the XorMon instance. If we stop those CPU utilization goes down.

Has anyone else had such performance issues? Or maybe some sizing recommendations?

Pavel

4 CPUs might not be enough.

IBMi OS agents are not so optimized on XorMon back-end as AIX/Linux ones where we expect thousands of them.

250 IBMi agents is quite a lot, never seen that.

Try to double CPUs to 8. Let us know.

Hello Pavel,

when we try to export the logs it loads for a second but nothing else happens.

Should the logs be downloaded by the webrowser or are they saved inside xormon server filesystem?

Pavel

they should be downloaded via web browser, check your browser download directory

as a workaround you can generate logs manually:

cd /home/xormon/xormon-ng # or your Xormon NG dir

cd server-nest

node dist/dump

It will generate file:

/home/xormon/xormon-ng/server-nest/files/tmp/logs.tar.gz

send it via email or https://upload.xormon.com
