I'm trying to make multi-host graphs out of the following rrd's:
[hobbit at mon rrd]$ find . -name processes\* |egrep 'web-12|web-13' ./web-12/processes.Apache_app1.rrd ./web-12/processes.Apache_main.rrd ./web-12/processes.Apache_app2.rrd ./web-12/processes.Apache_app4.rrd ./web-12/processes.Apache_app3.rrd ./web-12/processes.Apache_app3.rrd ./web-13/processes.Apache_app1.rrd ./web-13/processes.Apache_main.rrd ./web-13/processes.Apache_app2.rrd ./web-13/processes.Apache_app4.rrd ./web-13/processes.Apache_app3.rrd ./web-13/processes.Apache_app3.rrd
The rrds are simple process counts with "count" as the DS: [hobbit at mon rrd]$ rrdtool dump ./web-12/processes.Apache_app1.rrd |grep name <name> count </name>
Here is my hobbitgraph.cfg definition:
[processes-multi] FNPATTERN processes.(.+).rrd TITLE Multi-host Process counts YAXIS # DEF:cnt at RRDIDX@=@RRDFN@:count:AVERAGE -l 0 -A LINE2:cnt at RRDIDX@#@COLOR@:@RRDPARAM@ GPRINT:cnt at RRDIDX@:LAST: \: %10.1lf (cur) GPRINT:cnt at RRDIDX@:MAX: \: %10.1lf (max) GPRINT:cnt at RRDIDX@:MIN: \: %10.1lf (min) GPRINT:cnt at RRDIDX@:AVERAGE: \: %10.1lf (avg)\n
This looks to me like it should work, at least assuming that there are the same number of .rrd per host (there are), but I'm getting a broken graph image when I try to do a metrics report for multi-host processes counts. I have found that if I do a metrics report on a SINGLE host, the graph displays properly. Any idea what could be wrong?
