RE: [squid-users] Getting cache statistics

What I am really trying to do is to write an application that will allow
me to complex analyses of the efficiency of the squid cache after
changes are made to the squid configs or to the web server configs.
And, I am more interested in writing my own app than using one that
already exists. I really just wanted a way to get the squid performance
data without using SNMP and thought that it might be possible to do it
the same way as the cachemgr application does. As I have explored more
it seems that the cachemgr functionality is actually built into the
squid application and the cachemgr perl script is just a proxy to show
the data in a web browser. So, it seems that there is no raw data
access via any technique other than SNMP.

Thanks -Noah
