NimbostratusHow to get the line number of my Irule for debugging ?
Hi,
I use many IRules on my F5 BigIP to rewrite URLs for specific services. I logged these rewrited urls into local0.info but I would like to insert in that log the line concerned in my IRule script. Indeed, I used many if elsif... and I would like to get the line number of my script which will transform my url. Thus, in my log I could easily see which line in a specific script is concerned for rewriting url...easier to debug ;-)
A sort of "_line" variable I could use before writing my string to the log file. Any idea ?
Thanks for your help,
Regards,

Hi Nicolas,
I don't think there is a way to get the line number programmatically from an iRule. I suppose you could increment a local variable before each log line and log that though:
set counter 0
log local0. "$counter: my log message"
... iRule code ...
incr counter
log local0. "$counter: my next log message"
... iRule code ...
Or you could hard code the debug lines:
log local0. "1: my log message"
... iRule code ...
log local0. "2: my next log message"
... iRule code ...

Nicolas_MENOUX_Hi Aaron,
thanks for your quick reply. Yes, I think as you, there is no way to get the line number from the script...may be I'm wrong I hope so :-)
Increment a variable is a good solution but quite a nightmare to find the line after :-)
Anyway, I will try to change all of my if elseif endif blocs to be able to track the active line.
Thanks a lot,
Nicolas
