How does it work and what does it do?

Software has been tested with log files from Squid 2.5 STABLE 5 for

Windows NT 4.0/2000/XP/2003

Open a log file and start analysis. Wait for the results which are shown

in an table (detailled view) and in a text field (summary). You may then

export the results to a file.

Squideff checks every line of the Squid log file and assigns occurrence

and traffic to the different cache codes. Afterwards, traffic from cache

and internet are calculated.

For this project I have decided to work with signed 64-bit integers in order

to work with large numbers (–2^63..2^63–1). Despite that, it may be possible

that values exceed this range. In that case, please tell me (not that I know

what to do about it).

The following codes are calculated as data coming from the cache:

- TCP_HIT

- TCP_REFRESH_HIT

- TCP_REF_FAIL_HIT

- TCP_IMS_HIT

- TCP_MEM_HIT

- TCP_OFFLINE_HIT

- UDP_HIT

The following codes are calculated as data coming from the internet:

- TCP_MISS

- TCP_REFRESH_MISS

- TCP_CLIENT_REFRESH_MISS

- TCP_SWAPFAIL_MISS

- UDP_MISS

The rest is shown as not considered for efficiency:

- TCP_NEGATIVE_HIT

- TCP_DENIED

- UDP_DENIED

- UDP_INVALID

- UDP_MISS_NOFETCH

- NONE

• Squid Efficiency Analyzer interprets a Squid log (native) to determine how much traffic can be retrieved from the cache and how much comes from the webservers in the internet. Tested with log files from Squid 2.5 STABLE 5 for Windows NT 4.0/2000/XP/2003. Version 1.0, July 2004 Freeware (266,639 Bytes)
