It seems that a lot of people (including me) have a need to create custom graphs that require building an ext script for even the simplest guage type graphs. I'm about to go through the NCV docs and attempt to create a guage-type graph to track tomcat garbage collection times.
 
What would be cool is if hobbit had a way of handling simple tasks like this, defined on the server side in client-local.cfg, similar to the LOG option.
 
Here is an example of a tomcat garbage collection log:
 
$ tail -5 gc.log
15424.931: [Full GC 48511K->48216K(1022400K), 0.4856710 secs]
15485.431: [Full GC 48540K->48217K(1022400K), 0.4745360 secs]
15545.927: [Full GC 48513K->48218K(1022400K), 0.4845780 secs]
15606.449: [Full GC 48513K->48215K(1022400K), 0.5136750 secs]
15667.010: [Full GC 48511K->48216K(1022400K), 0.5008330 secs]

It would be so cool if you could make a definition in client-local.cfg similar to:
 
"graph:filename:PATTERN:x-axis_name:y-axis_name"
 
So an example usage of this would be:
 
graph:/var/log/tomcat/gc.log:"%.+%d.%d secs":"Garbage Collection":seconds
 
Just an idea for the drawing board :) Hmm this would also solve my problem of ext scripts having unique names in a shared directory :)
