I thought I had seen a script that allowed a user to select the servers and graphs they wanted to show on one graph...similar to the admintools script but a dynamic form-based rrd tool...I'll dig around some more to see if I can find it again...if I remember right, it didn't care how many rrds or their relationships on a graph...so you could potentially have 15 servers on one graph (all showing different info but only the first one's y-axis...)

Hi Charles,

didn't you get the mail I sent you friday ? Here is it again:

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?

Can't find it...but I have been playing around with drraw a bit...not successfully, but if they ever get it working with rrd 1.2 it'll be a nice option to use with hobbit...
