Hey there,
I seem to be having the same issue posted by John Alberts on Sep 19. Was a
resolution ever discovered?
Thread: http://comments.gmane.org/gmane.comp.monitoring.ganglia.general/3104
I'm setting up a brand-new Ganglia instance, compiled from Source RPM on OEL
5u6. (I believe John was running CentOS EL5u6 as well.) libconfuse and and
apr installed from EPEL. Pretty standard config.
It seems to only affect the load and network reports. Other graphs, memory,
cpu, etc work fine.
Apache error log shows:
ERROR: invalid rpn expression in: a0,a2,ADDNAN,a3,ADDNAN,
Debug:
/ganglia/graph.php?me=unspecified&m=load_one&r=hour&s=by%20name&hc=4&mc=2&g=load_report&z=medium&debug=5
