@george1421 If you can locate the thread that Tom gave these instructions and/or a wiki article on how to do it, I am more than willing to try. I appreciate your time on this.

@george1421 I did indeed reboot and didn’t see any difference. On a gut feeling, I doubled the checkin time from 180s to 360s and that has marginally helped the CPU usage. I am just puzzled why this wasn’t an issue at the end of the last school year? Our number of clients has not changed and I have been on 1.5.4 for a while now. Here is the graph of my current CPU Usage on that VM. You can see where it was at, when I made the setting change in www.conf, changing the checkin time, etc:

I did notice I still had many php-fpm processes, but overall utilization seems to be down:

EDIT: I did forget to mention I have this running on 2vcpus and 8GB of Memory. Do I not have it specced high enough?

Hi George,
Most of these settings were set properly. Below are the ones I set:

pm.max_children = 35
php_admin_value[memory_limit] = 256M

A reboot after that still yields 100% usage and way too many php-fpm processes.
I have about 1300 devices using the FOG client. I realize this is a lot, so I did set the checkin time to 180s. Do you think increasing that more would help?

Thanks!

Hello All,
I came in this morning to a few alarms on my VM environment about Guest CPU Usage. Tracked it down to my fog server which I then found was chugging at 100% cpu utilization. Here is a screenshot of the “TOP” command run as root:

I am also getting many “Max children reached” messages in the php-fpm error log on the Web UI.

I am running 1.5.4 on CentOS7.
Thanks!
Paul

@sebastian-roth OP also mentioned separate virtual and physical environments. It just occurred to me he can use the physical server for his physical subnet utilizing one of the NIC’s and just spinning up a linux VM for FOGing on his Virtual subnet. No additional cost this way. Good thinking.

@fernando-gietz I feel foolish now. This taught me the lesson that I shouldn’t change multiple variables when trying to troubleshoot an issue.

Here is a screen shot of my working config:

I think I had an incorrect group search DN set. When I put the correct DN I also messed around with the Group Member Attribute. I changed it back to sAMAccountName and presto! Thanks for everything boys!

Kinda bumping this thread/trying to help. Kind of thinking out loud, but this would involve 2 IP helper addresses on the networking side, two DHCP option 66 ip addresses, and somehow specifying 2 IP’s on the FOG server itself.

Does FOG handle your DHCP?

@fernando-gietz Is there a different way in the DN language to designate spaces? I tried single and double quotes but it didn’t stick. In the actual AD structure (much to my chagrin) there are spaces.

@fernando-gietz I believe I have successfully bound. However, when I try to log in as myself, I see the below error in /var/log/php-fpm/www-error.log

I believe the issue is in my search dn.

I am trying to log in as fry_p. I am a member of the security group “fogusers” in AD. It can be found here:
CN=fogusers,OU=Security Groups,OU=Domain Users,DC=domainhere,DC=org

fry_p is a member of this group.

@fernando-gietz Does the built in Domain Admin have such permissions? That’s the account I am using.
