[squid-dev] Squid-Cache statistics reporting project

[Eliezer Croitoru]

Hey Alex,

Thanks for the kinds words and recommendations.
Since I already have some of the code ready and most of the clients do not
have a version with YAML cache mgr output available I would say
that this is the best choice.
I offer this as a Squid-Cache statistics project and not a personal one.

Any directions on this, @Amos @Kinkie?

Thanks,
Eliezer

Just to avoid misunderstanding: If "this idea" refers to offering your 
script to Squid users that want to participate in your project, then you 
do not need a squid-dev blessing for doing that because that idea does 
not require any Squid modifications.

If you are proposing Squid modifications, then please detail those 
modifications. I hope it does not come to Squid duplicating crontab and 
sendmail functionality :-).

As a personal project, that converter sounds good to me! FWIW, I have 
heard of 3rd party tools[1] that parse Squid cache manager output, but I 
do not know how suitable they are for what you want to achieve. The best 
output format would depend on how you plan to post-process data, but 
once you get something that follows strict grammar, it should be fairly 
easy to convert to other formats as needed. I would just keep the 
converter script output as simple and strict as possible to facilitate 
further conversions and input in various post-processing tools.

As an official Squid project, I think it would be much better to finish 
converting cache manager code to produce YAML output natively than to 
develop and maintain an official converter script (while still working 
on that native YAML conversion).

Personally, I am worried that glimpses based on a few 
volunteer-submitted samples are more likely to mislead than to correctly 
guide Squid development, but that speculation cannot be proven.


Cheers,

Alex.
