Hi,

I am trying to create my own command parser and I have few question that I was hoping someone could help answer. I used this document

docs/DOC-3168

to learn how to make a parser and I also studied the existing df.py parser and kind of modeled my parser after so

for the 'scanners' plugin, what is the purpose of the '\d+' in (?P<availableBlocks>\d+). I understand what \d+ means in terms of python regex but is that \d+ the regex of the variable <availableBlocks> or is that saying it has trailing digits after the variable?

Also in the df.py example there as a line called componentSplit which seemed to tell where to start parsing. Is that right? My parser starts on the first line so I commented this line out. Is that the right way to do it or should I keep it and just leave it empty like so: componentSplit = ''"

Basically I am trying parse an output like so

Fri, 14 Oct 2011 13:23:25 EDT: Instance1

Performance_1=0|Performance_2=224|

Here is an small example of the parser I wrote:

from Products.ZenRRD.ComponentCommandParser import ComponentCommandParser

class custom_parse(ComponentCommandParser):

#    componentSplit = ''

    componentScanner = '^\w{3}\,\s\d{1,}\s\w{3}\s\d{4}\s\d{1,}\:\d{2}\:\d{2}\s\w{3}\:\s(?P<component>)'

    scanners = [

        r' Performance_1=(?P<Performance_1>\d+)\|Performance_2=(?P<Performance_2>\d+)\|'

                     ]

componentScanValue = 'Instance_Number'

The zenoss created a pyc file for parser.py. I am currently getting the following error

Thanks for any help
