High MySQL CPU Usage Bogging Down Server

@uwpviolator said in High MySQL CPU Usage Bogging Down Server:
I did update a handful of machines (manually) to the new FOG Client 11.14 for testing.
It’s possible the high CPU load is being caused by most of the clients being an older version. @Joe-Schmitt thoughts?
-
@wayne-workman So you’re saying because there are just a few 11.14 FOG clients? Currently the client on the Fog Server is 11.12.
-
Just checking machines now and I am finding this. So we need to reset encryption

Can’t hurt.
-
@wayne-workman Rest Encryption but clients could not reach server to get cert so they keep trying and trying. Killed for service via GPO and will bring back online. It has already come back under control but we will have to see come tomorrow.

What’s the new error in the fog.log file from one of them? Please give us the whole ‘section’ where the error is.

@uwpviolator said in High MySQL CPU Usage Bogging Down Server:
Can you actually access your FOG Server with that address?
http://fogserver/fog/management -
@wayne-workman Yes but this only after we killed the FOG service on clients. That freed up the CPU to start allowing clients to authenticate again.
-
@uwpviolator I see. Can you check your Apache error log for problems?

MySQL might be crashing - or running out of buffer space or ram. What’s your max clients set at? Max packet size? Those are mysql settings.
-
One log shows .11.12 and the other shows 0.11.14, are you getting logs from the same machine?

@tom-elliott No.
Been working on getting Windows 1709 working with FOG. Put the new client on about 30 machines to test last week. Our admin doesnt want to update FOG until there is a stable release. Was told I could have 11.14 in my environment but my server only has 11.12 on it. Have not added it to push out.
-
@wayne-workman I upped max connections to 1000 today. Before it was 500
Maximum number of connections 1000
Query cache size in bytes 256MB
Maximum packet size 16MBEverything else is default
-
@uwpviolator I understand just wondering why were seeing three logs from different machines. I’ve seen versions 0.11.12 0.11.13 and 0.11.14.
I’m just trying to get information. I doubt the version client you’re running is the problem. Maybe client checkin time is too low?
-
@tom-elliott No our admin just upped that on Friday to.
-
@uwpviolator This would retrieve logs for MySQL:
journalctl -u mysql.serviceOr if using mariadb:journalctl -u mariadb.service
Anything interesting in there? Use your arrow keys to navigate up/down/left/right. -
@wayne-workman said in High MySQL CPU Usage Bogging Down Server:
journalctl -u mariadb.service
Nope it just says start and stop service.
