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
