      this is the error in the fog_error_log

      Archive: binaries1.4.3.zip
      End-of-central-directory signature not found. Either this file is not
      a zipfile, or it constitutes one disk of a multi-part archive. In the
      latter case the central directory and zipfile comment will be found on
      the last disk(s) of this archive.
      unzip: cannot find zipfile directory in one of binaries1.4.3.zip or
      binaries1.4.3.zip.zip, and cannot find binaries1.4.3.zip.ZIP, period.

        @anthony-delarosa Are you running the installer as root/sudo?

              one thing I did notice is that https://svn.code.sf.net/p/freeghost/code/tags/1.4.4 does not get binaries1.4.4.zip but instead binaries 1.4.3.zip which is what is looking for so that’s fair but one thing that is different about that zip file is that the owner if root and not fog like the rest of the folders

                Ooooohh so you’re using svn not git? That might be the problem.

                What does git branch bring up if /root/fogproject/ ?

                  I initially set it up with subversion back in the day so i kinda stuck to svn on every upgrade! i’ll give GIT a try

                    Sure. 🙂 If you want to upgrade to the dev-branch (I would) we can go from there and see if it’s any better. 🙂

                      @themcv hey, i upgraded using GIT and now i’m on 1.4.4 and now running top:

                      and this is vSphere performance for CPU

                      does FOG generally use that muchCPU MHz? it is the VM that uses most CPU in this VM Host:

                      Seems like quite a lot to me

                        @anthony-delarosa How many client computers (with fog client installed) are on your network? With mysql at 27% it sounds like you have quite a few checking in.

                        Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                          @george1421 we do, easily over 800 clients! i was not aware that the clients would be checking in with FOG! I thought it was FOG that would contact the host if it needed to communicate something to it

                            @anthony-delarosa No the fog client works the other way around, the clients check into the master fog server for things to do. They also post inventory info and such.

                            Since you have a great performance data so far, I wonder if you would be willing to help the fog project by doing something I had on the back burner for a while.

                            The idea is simply to install php-fpm and have apache use that instead of its internal php engine. I’m interested to know how that impact:

                            1. Performance of the web gui
                            2. Impact on performance of the entire fog server CPU usage.

                            I see you are using an older OS, but the php-fpm package should still be available in epel or in the centos repository. If you have a little time to test this idea let me know and I will put together a tutorial on how to set this up. Reverting back to the default apache php can be done by just commenting out one line. I would do it on my production fog server, but I only have a small campus. I’ve been looking for someone who had around 1000 clients to see if the test was dramatic.

                            Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                              @anthony-delarosa In your case you can in crease the check-in delay to help with cpu usage on your fog server. You can do this with the understanding that it will also take longer for clients to see snapin deployments and other assigned tasks. It will not impact image deployment only fog client tasks. (but I’d like to see the results of the php-fpm test before you make this change if you agree).

                                The fog client uses polling to communicate with the fog server, this is detailed here: https://wiki.fogproject.org/wiki/index.php?title=FOG_Client#Polling_Behavior

                                      @anthony-delarosa Excellent, thank you.

                                      Here are my thoughts on how to set this up. I’m only posting below for my reference. I want to spin up a Cento 6.7 FOG server tomorrow and test the process out before you implement it. I also want to see if memcache will help with the process too. But I need to do a bit more research first.

                                      # yum install php-fpm
                                      # chkconfig --levels 235 php-fpm on
                                      
                                      Edit /etc/php-fpm.d/www.conf to use sockets
                                      
                                      # vi /etc/php-fpm.d/www.conf
                                      
                                      ;listen = 127.0.0.1:9000
                                      listen = /tmp/php5-fpm.sock
                                      
                                      listen.owner = apache
                                      listen.group = apache
                                      
                                      # service php-fpm start
                                      
                                      Setting up Apache and mod_fastcgi
                                      
                                      Install the RPMForge repo:
                                      
                                      # wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
                                      # rpm -ivh rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
                                      
                                      Add some priorities which repo to use:
                                      
                                      # yum install yum-priorities
                                       
                                      # vi /etc/yum.repos.d/epel.repo 
                                      ... add the line priority=10 to the [epel] section
                                      
                                      # yum install mod_fastcgi
                                      
                                      Configure mod_fastcgi
                                      
                                      If you have php enabled disable it

                                        @anthony-delarosa Yes that is the right setting, default check in time is 5 minutes. But if you can hold off a day or so until we can test the php-fpm code. I want to see if it makes a difference on the default settings for FOG. In ‘theory’ it should make a dramatic difference in overall FOG performance.

                                        Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!
