Adding custom LARRD graphs

[Charles Jones]

How difficult is it to add custom graphs?  For example we have several 
Oracle standby databases that "resync" (import binary database 
changelogs) for several hours every night. I have a perl script which 
parses one of the logfiles created by this process, and gets values like 
the total time it took to import each binary log. Having a graph of the 
average time it takes to process would be VERY handy for metric and 
scaling evaluations.

The long story short is that I have a script or process that outputs 
numbers that I want to graph with Hobbit+LARRD. Is it possible?  Or, I 
should be asking, how difficult would it be, and can you give any 
pointers on what to do.

Thanks,
