CPU Usage 100%

[george1421]

@anthony-delarosa Ok when you are ready we can move forward. These instuctions are not destructive and can be reversed with a comment in a config file and restarting apache.

Here is where I’ve been documenting the config changes: https://forums.fogproject.org/topic/10717/can-php-fpm-make-fog-web-gui-fast

The change to my server has made a difference in web gui response time. But again I don’t have a large campus so its hard to scale how much of a change its made. The instructions I created were for centos 7, but should translate to 6.7 without issue. If you run into an issue I’m spinning up a 6.7 instance of centos just to be sure.

As part of your task. I would like you to track in vmware vm cpu usage to see when you turn on php-fpm if there is a change (in either direction) or no change. There are two parts I want to test one step at a time.

1. Enable php-fpm
2. Turn on memcache to store temporary session information in memory instead of the file system.

Your vm should have 3-4 GB of ram for this test. If you have more already then that is fine. I just want to make sure we have room to spawn up everything.

@anthony-delarosa Do you have golden images going? I’ve not ever heard of 2TB of images before! Then again, I don’t think anybody has had as big of a FOG environment as you. : )

[anthony.delarosa]

@themcv glad to know we are the first then we use FOG for all our images and since I work for a studios company with various different shows, each show kinda has their own image! the guys have their reasons so they do a raw windows 7, 8.1, 10 images for all models then a pre-sys image once they have all the applications installed and then a production image so times 3x images per OS per model! yeah that adds up quickly lol

[THEMCV]

@anthony-delarosa Wow, that is a lot. Consider me in awe of your installation. : )

So is each image different software or is it more for each model?

[anthony.delarosa]

@THEMCV both different in software and different model plus different OS so yeah it adds up! Mind you we’re a company with over 700 fx/animators/lighters/compositors etc…

@anthony-delarosa That’s nuts. Glad to see it in such a large deployment. Have you thought about doing golden images and just having varied images for software deployments?

@anthony-delarosa said in CPU Usage 100%:

This is off topic I know, but you should really have them use regular images instead of raw - there’s several options - ones that resize, ones that do not, lots of compression options. It’s light-speeds faster than raw, I really do mean light-speeds faster.

[THEMCV]

@wayne-workman I just noticed that too. @anthony-delarosa I agree, unless there’s a specific reason that you have, I would look into not doing raw.

[anthony.delarosa]

@george1421 hey! i’m ready to do this today, are you around?

[george1421]

@anthony-delarosa Yes I’m available. Make sure you have a good baseline of usage. Your vmware trending is good enough. If the process works correctly you should not see all of those httpd instances in top since it should spawn php-fpm instances.

Is your check in time still set to FOG defaults?

[anthony.delarosa]

@george1421 hey yeah it’s still set to 600! should i just follow: https://forums.fogproject.org/topic/10717/can-php-fpm-make-fog-web-gui-fast instructions?

[anthony.delarosa]

@george1421 already a problem, i don’t have /etc/httpd/conf.modules.d i have /etc/httpd/modules full of mod_***.so files but none with 00-mpm.conf file could this be a CentOS 6.7 to 7 difference?
