[Orca-users] working with mixed-column data sources...

[Steven McPhillips]

I've got what I suppose could be called a normalised file format -  
instead of having every log entry stored on the same line (as with  
the orcallator source), my log entries have a recType column, for  
instance. This column defines what type of data is being stored for  
that record - could be JVM memory allocation, website user sessions,  
current active threads etc. All up, my logfile has about 3 of these  
"type" columns, along with a timestamp and "value" column.

How easy / difficult would it be to use Orca to plot my data? After  
looking at the orca man page, I get the feeling it might be quite  
difficult, although perhaps do-able using some judicious regexps for  
the plot data entries. If someone on the list can give a simple yes/ 
no answer that would be great - I don't mind having to refactor the  
log format via a pipe for orca to read in if I have to, but naturally  
I would like to be neater if there is a better way!

thanks in advance for any assistance,

Steve
