Description of problem: With two "clusters" configured in Ganglia, the "grid" view is the default web page, with a pull-down for the other cluster sources. When selecting any cluster report, the four overview default graphs do not show. Version-Release number of selected component (if applicable): ganglia-3.7.1-3.el7.x86_64 ganglia-gmetad-3.7.1-3.el7.x86_64 ganglia-web-3.7.0-3.el7.x86_64 ganglia-gmond-3.7.1-3.el7.x86_64 How reproducible: Steps to Reproduce: 1. configure two data_source clusters and a gridname with gmetad.conf 2. collect some metrics from some gmond members in each cluster 3. browse to the default web page and "Choose a Source" from the pull-down Actual results: The graphs for Cluster Load, Memory, CPU, and Network are missing from the Overview. They are also missing from the Mobile -> Clusters -> "Name" -> Cluster Summary page. Expected results: The graphs for Cluster Load, Memory, CPU, and Network should show for each cluster as they do in the default Grid Overview. Additional info: We were able to work around this and get all default graphs back by making an additional copy of the default.json config file. This seems broken and not obvious. # cp /usr/share/ganglia/conf/default.json /var/lib/ganglia/conf/ P.S. We love Ganglia, and were rocking the old EPEL6 build. Thanks for the upgrade!
I see the same with only one cluster defined. The 4 summary graphs are missing on both grid and cluster views. ganglia-gmond-3.7.1-2.el6.x86_64 ganglia-web-3.7.0-2.el6.x86_64 ganglia-gmetad-3.7.1-2.el6.x86_64 ganglia-3.7.1-2.el6.x86_64 CentOS release 6.6 (Final) httpd-2.2.15-45.el6.centos.x86_64
This is a bug in the ganglia-web packaging, we were packaging ganglia in house for years and it broke as soon as we moved to the epel packages. After some digging I've found the problem is that the ganglia-web configuration directory is defined as /var/lib/ganglia/conf, yet the json configuration files are delivered to /usr/share/ganglia/conf/ [root@holmes ~]# grep conf_dir /usr/share/ganglia/host_view.php if ( is_file($conf['conf_dir'] . "/default.json") ) { json_decode(file_get_contents($conf['conf_dir'] . "/default.json"), [root@holmes ~]# grep gweb_confdir /usr/share/ganglia/conf_default.php $conf['gweb_confdir'] = "/var/lib/ganglia"; [root@holmes ~]# grep conf_dir /usr/share/ganglia/conf_default.php $conf['conf_dir'] = $conf['gweb_confdir'] . '/conf'; [root@holmes ~]# rpm -ql ganglia-web | grep default.json /usr/share/ganglia/conf/default.json If this were repackaged with the files in /usr/share/ganglia/conf/ either moved or copied to /var/lib/ganglia/conf the problem would be resolved.
Finally reproduced the bug, thanks! However, unsure how to fix, ganglia-web wants write access to dir gweb_confdir, hence it must be in /var/lib somewhere, adding symlinks back to /usr/share/ganglia/conf/ for default.json event_color.json, view_default.json might be a possible. Or wants ganglia-web to write to those files as well?
Since /usr is supposed to be read-only and ganglia documentation recommends adding optional reports to default.json so I don't think linking from /var/lib to /usr/share is the best idea. When you compile ganglia from source, the default value of gweb_confdir is /var/lib/ganglia-web/conf which seems to be purposefully kept separate from the gmetad root configuration directory /var/lib/ganglia/conf is there any reason not to do it this way? From the ganglia-web Makefile on github: # Gweb statedir (where conf dir and Dwoo templates dir are stored) GWEB_STATEDIR = /var/lib/ganglia-web # Gmetad rootdir (parent location of rrd folder) GMETAD_ROOTDIR = /var/lib/ganglia
