Working on updating my current ganglia installation, starting with the web front end. Everything works as expected except for the views functionality. This json file, for example:
{ "view_name": "boo", "default_size": "medium", "items": [ { "hostname": "if01.fnal.gov", "metric": "load_fifteen", "vertical_label": " ", "title": "Fifteen Minute Load Average" } ], "view_type": “standard” } Produces a graph with the generic “No matching metrics detected” error. I’ve traced it to graphs.d/metric.php where it appears the variable $rrd_dir is not set. If I click on the graph to get the url and add debug=2 to the end of the url trying to produce it I see this error in the apache logs: [Tue Dec 10 15:01:45 2013] [error] [client 131.225.88.123] Graph [metric] in context [] [Tue Dec 10 15:01:45 2013] [error] [client 131.225.88.123] Final rrdtool command: /usr/bin/rrdtool graph - --start '-3600s' --end now --width 650 --height 300 --title load_fifteen --vertical-label ' ' --slope-mode HRULE:1#FFCC33:"No matching metrics detected" If I modify the url from this: http://fefdev.fnal.gov/ganglia/graph.php?r=hour&z=xlarge&m=load_fifteen&h=if01.fnal.gov&vl=+ to this: http://fefdev.fnal.gov/ganglia/graph.php?r=hour&z=xlarge&m=load_fifteen&h=if01.fnal.gov&vl=+&c=MINERVA A valid graph is produced. I’m no expert on the ganglia code, but it seems like without the context being set, the web front end can’t find the rrd files? Am I interpreting that correctly? Curiously, any views that use regex matching for hosts is working just fine. Everything else about the web interface is working also.. but unfortunately I can’t move forward on the upgrade without the working views as users are expecting them to be there. ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
