HIGH CPU Fog Services after update r5029 v6759
-
@baggar11 Can you give us the last 500 or so Image Replicator logs? FOG Configuration -> LOG Viewer -> Image Replicator.
Also, you might just look through all the logs in there for anything out of place.
-
@baggar11 does ubuntu 14.04 use systemctl?
Is there anything spewing into your /etc/apache2/error.log

Get in contact with me (chat bubble in the top right corner) if you want to join in.
Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

@Wayne-Workman Here you go. 500 lines of logs.
EDIT: Forgot to select Image Replicator. Here it is.

@Tom-Elliott Here’s what I’m seeing after stopping all services, clearing the logs and then rebooting.
cat error.log [Wed Mar 16 16:10:53.258602 2016] [mpm_prefork:notice] [pid 946] AH00163: Apache/2.4.18 (Ubuntu) OpenSSL/1.0.2g configured -- resuming normal operations [Wed Mar 16 16:10:53.258795 2016] [core:notice] [pid 946] AH00094: Command line: '/usr/sbin/apache2' [Wed Mar 16 16:11:35.735081 2016] [:error] [pid 950] [client 192.168.10.15:53300] PHP Strict Standards: Only variables should be passed by reference in /var/www/fog/lib/pages/dashboardpage.class.php on line 71, referer: http://192.168.10.14/fog/management/index.php -
@baggar11 What services are using the bulk of the CPU?
-
@Tom-Elliott For a full view of processes, I gave an output of ps aux | grep FOG down below. These are the top 3 though.
FOGImageReplicator
FOGMulticastManager
FOGSnapinReplicator -
@baggar11 And they’re constantly cycling CPU?
-
@Tom-Elliott Uptime is now at 17 minutes and nothing has changed in CPU cycle regard.
-
One thing that I noted was interesting was after an upgrade, cpu cycles are normal. System is idling. FOG WebUI works fine, no issues.
Once I restart the virtual machine and the FOG services start up on boot, that’s when those 3 services start consuming all of the cpu.
-
@baggar11 Well, there’s 5 total services.
That said, it seems this is somewhat well known about, and our method to “check” and correct isn’t working properly. It only seems, to me, to impact Ubuntu (Maybe older versions of Debian?)
I know the problem, in the past, was related to the network (maybe other required services) aren’t running when the FOG Services start up.
Maybe try adding a sleep 30, then manually start the services by the use of the rc.local file.
Basically the rc.local is processed LAST and by that time, network may still not be up, so the sleep time just ensure’s it has ample time to come up.
Try disabling the FOG Services from starting at boot.
Then, edit the /etc/rc.local file.
Add:
sleep 30 /etc/init.d/FOGPingHosts stop /etc/init.d/FOGScheduler stop /etc/init.d/FOGImageReplicator stop /etc/init.d/FOGSnapinReplicator stop /etc/init.d/FOGMulticastManager stop /etc/init.d/FOGPingHosts start /etc/init.d/FOGScheduler start /etc/init.d/FOGImageReplicator start /etc/init.d/FOGSnapinReplicator start /etc/init.d/FOGMulticastManager startThis should put the service files to a point where they’re not constantly looping (which is what’s most likely causing the CPU load in the first place.
-
Sorry guys! I have been rolling the dev version for so long without issue, I totally forgot about the startup services possibly being an issue. I’m all set now. Here’s what I did.
Ran this on each service
sudo update-rc.d FOG*service* disableThen, as suggested, added these line to my rc.local
sleep 5 service FOG*service* start -
@baggar11 Very nice.

@Raymond-Bell Just going to guess but the Storage nodes, currently, are unable to talk with the main FOG Server?

Editing the rc.local file now will let you know after reboot

@Raymond-Bell are you disabling the services from booting completely? Then using the rc.local?
THe rc.local won’t work if it can’t stop the original tasking anyway.
