[Orca-users] modifying data for plots

[Mark Parsisson]

I have a set of log files that contain data that is not 100% numeric.
For example, I have:

 

...

1080161171      Memory usage: total:497.54 Mb - used: 123.22 Mb (25%) -
free: 374.32 Mb (75%)

1080161461      Memory usage: total:497.54 Mb - used: 123.23 Mb (25%) -
free: 374.30 Mb (75%)

1080161761      Memory usage: total:497.54 Mb - used: 123.29 Mb (25%) -
free: 374.25 Mb (75%)

1080162071      Memory usage: total:497.54 Mb - used: 123.29 Mb (25%) -
free: 374.25 Mb (75%)

1080162371      Memory usage: total:497.54 Mb - used: 123.29 Mb (25%) -
free: 374.25 Mb (75%)

...

 

This is the memory usage for a single server. As you can see, the
percent used and percent free has extra characters. Is there a perl
expression I can use on the data line in the plot definition of
orcallator.cfg to strip off the (%) ? 

 

Alternately, is there a way I can split the first number from the
"total:" and again get just a number to plot? 

 

I need to understand if I can do this (using perl - although I don't
know perl) in the data line or if I need to find a way to modify my log
files (much more effort than it sounds like :-(

 

Thanks,

Mark
