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.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>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.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Here is an example of a tomcat garbage collection
log:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>$ tail -5 gc.log<BR>15424.931: [Full GC
48511K->48216K(1022400K), 0.4856710 secs]<BR>15485.431: [Full GC
48540K->48217K(1022400K), 0.4745360 secs]<BR>15545.927: [Full GC
48513K->48218K(1022400K), 0.4845780 secs]<BR>15606.449: [Full GC

48511K->48216K(1022400K), 0.5008330 secs]<BR></FONT></DIV>
<DIV><FONT face=Arial size=2>It would be so cool if you could make a definition
in client-local.cfg similar to:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial
size=2>"graph:filename:PATTERN:x-axis_name:y-axis_name"</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So an example usage of this would be:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>graph:/var/log/tomcat/gc.log:"%.+%d.%d
secs":"Garbage Collection":seconds</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Just an idea for the drawing board :) Hmm this
would also solve my problem of ext scripts having unique names in a shared
directory :)</FONT></DIV>
