Hello all, I originally posted this message to the ganglia-users list, but I never received a response so I figured I'd go ahead and email the ganglia-developers list.
As with usual mailing list respect, I apologize if I have somehow missed a pre-existing thread that covered the error that I'm experiencing and cannot seem to solve. I've noticed that my larger clusters (60+ nodes) don't report stacked graphs properly, i.e. (and specifically!) "load_one". All I get is a broken image link with the following error log snippet taken from an Apache log: ERROR: parameter 'a139' does not represent a number in line STACK:a139#E50009:foo_hostname I also ran the rrdtool command on the console itself (taken by adding &debug=5 into the graph URL) afterwards and got the same error: ERROR: parameter 'a139' does not represent a number in line STACK:a139#E50009:foo_hostname I've tried updating rrdtool from 1.2.27 to 1.4.5-1; taking a shot in the dark by updating stacked.php per https://github.com/ganglia/ganglia-web/issues/114 and https://github.com/jbuchbinder/ganglia web/commit/727b1ffc9e3e8a2979ea23107acefca53ef5ddf0 (although stacked.php in ganglia-web 3.5.2 already has this in place); adjusting timeouts within Apache and PHP (another shot in the dark); removing the "load_one.rrd" from /var/lib/ganglia/rrds... directory; restarts of both gmetad and gmond (although it definitely seems to be an rrdtool error). I've searched through the rrdtool user mailing list and haven't found any useful posts. I was wondering if anyone else has run into this issue before and if they were able to get it resolved and if so, what suggestions one may have.
