free-sa.conf(5) Statistic Analyzer free-sa.conf(5)NAMEfree-sa.conf - Configuration file for free-sa statistic analyzer
DESCRIPTIONfree-sa.conf configures the free-sa statistic analyzer, free-sa(1).
FILE FORMAT
The file consists of options with arguments, comments and empty lines.
Each line that starts with a hash (#) symbol is a comment. Options and
arguments are case sensitive and of the form: Option="Argument".
The arguments are of the following types:
STRING Set of characters.
BOOL Boolean value: 'true' or 'false'.
INTEGER Signed integer.
free-sa.conf file sample is included in distribution, check it at
/usr/local/etc/free-sa/free-sa.conf.sample.
Note: file should end with empty line.
Note: you may use 'true'/'false', 'yes'/'no', 'enable'/'disable',
'1'/'0' in any case as boolean value and only first symbol is
significant for boolean value, i.e. for example, you may use
just 'T' instead of 'true'.
OPTIONS
cache_directory="STRING"
Full path to directory where free-sa should temporarily keep its
cache files used for reports generation.
Default: /var/cache/free-sa.
configuration_name="STRING"
Configuration name, will be showed in list report (LR) and index
report (IR).
Default: undefined, in this case full path to configuration file
will be used as configuration name.
email_address="STRING"
Generate top users report in text format and send it to e-mail
specified by STRING. If STRING is '-' then report will be showed
on stdout. You may overwrite this value via '-e' command line
option.
Default: undefined, i.e. report is disabled and nothing will be
sent.
global_filter="STRING"
Full path to global filter file. Check "FILTER FILES" section
below.
Default: undefined, i.e. global filter disabled.
index_show_calendar="BOOL"
Show calendar menu with search box at index report (IR). This
menu simplifies navigation across reports dated by various
months and years and allows to search on-the-fly by report name.
Default: true.
index_sort="STRING"
Sort field(s) and order for index report:
B Bytes (desc.), generation date (desc.)
b Bytes (asc.), generation date (desc.)
D Generation date (desc.)
d Generation date (asc.)
N Configuration (desc.), generation date (desc.)
n Configuration (asc.), generation date (desc.)
U Users (desc.), generation date (desc.)
u Users (asc.), generation date (desc.)
Default: D, i.e. generation date (desc.)
locale="STRING"
Locale to switch to after command line options parsing.
Note: you should specify command line options arguments in run‐
time locale format, not this one.
Note: it's useful when you schedule free-sa run via crontab,
because usually crond sets C or POSIX locale.
Default: undefined, i.e. use current locale.
local_filter="STRING"
Full path to local filter file. You may define multiple local
filters using multiple 'local_filter' options. Local filters
defined within first 8 'local_filter' lines counted from top of
free-sa configuration file will have indicators while the rest 8
will not. Check "FILTER FILES" section below.
Default: undefined, i.e. all local filters are disabled.
log_file="STRING"
Full path to log file. Log file should be in one of the sup‐
ported log file formats, check free-sa(1) "Supported log for‐
mats" and 'logformat' option below. You may overwrite this value
via '-l' command line option.

3 Postfix 2.x over syslog log format
4 Qmail over syslog log format
5 Communigate pro 5.x native log format
Note: support for NetCache and Blue Coat proxies is EXPERIMENTAL
and implemented only via Squid 2.x native log format. For these
log formats you probably should enable 'skip_errors' option.
Default: 0.
log_skip_errors="BOOL" (EXPERIMENTAL)
Try to skip erroneous records presented on log and continue log
analysis from next record.
Note: this option is EXPERIMENTAL and implemented only for stan‐
dard log analysis, i.e. not for cropping log or showing log
information or free-sa.cgi.
Default: false.
log_time_zone_shift="INTEGER"

ing remove records from log file and show log file information
actions.
Default: 0, i.e. no time shift.
real_time_home="STRING"

in real time report (RTR). This option allows easy relocation of
the free-sa.cgi binary to any directory on a web server side.
Default: ..
real_time_timeout="INTEGER"
Update interval for real time report (RTR) page in milliseconds.
Default: 5000, i.e. 5 seconds.
recipient_tolower="BOOL"
Convert recipient name (URL) to lower case. It should be useful
for mail logs where recipient's e-mail address may appear in
different cases thus not allowing to collate these e-mail
addresses as one and unique recipient.
Default: false.
reports_bytes_divisor="STRING"
Select bytes field represence in all reports except server effi‐
ciency. Actually divisor option value is letter, which is lowest
meaning digits order (except 'v'/'V' values). The lower case
letter means number rounded to integer without digits after dec‐
imal delimiter value. The upper case letter means number with
two digits after decimal delimiter value. All divisors in divi‐
sions is 2 in the power of interpreted option value (i.e. 1
kbyte = 1024 bytes).
Allowed option values and their effect on bytes field in reports
is showed below using example for 123, 456768 and 789123456
bytes field values. Locale is assumed with ' symbol as thousands
separator:

For example, this could be useful when you have multiple authen‐
tication schemes enabled in Squid and you see exactly same user‐
names with and without domain prefix/suffix in reports. When
this option is enabled domain prefix/suffix will be removed thus
all user stats will appear under one username.
Note: string removal is performed after unescape and internal
conversation to lower case with removal of special characters
are applied.
Note: do not use this option if STRING may appear in the middle
of username because in such case username will be truncated
starting from first entrance of STRING pattern in username. Due

report for every site visited by user is placed to the separate
file. This option is useful when number of unique sites and
therefore URLs per one user is big.
Default: false.

Filter file examples
1. If we want to see only records related to users with
'192.168.0.15', '192.168.0.27' IPs, and see their accesses to all sites
except 'www.ourcorporatesite.com', then we can make following global
filter file contents:
I 2
i 192.168.0.15
i 192.168.0.27
U 1
u tp://www.ourcorporatesite.com
2. If we want to see records related to Code Red, Code Red 2 and Nimda
viruses activity at local filter report, then we can make following
local filter file contents:
U 0
u XXXXXXXXXXXX
u NNNNNNNNNNNN
u cmd.exe
3. If we want to see only URLs of actually downloaded images in gif
format at users reports and top sites report, then we can make follow‐
ing users filter file contents:
U 4
u \.(gif|GIF|Gif)$
S 0
s 0
SVG REPORT DEFINITION
SVG report definition is string of characters allows you to define SVG
report view.
String format
String may start with number following characters which enable various
SVG report view options.
number Generate report for top number entries only (for top
sites and top users SVG reports only).
l Show legend (for pie chart only).
p Generate pie chart instead of bars.
r Generate bars in relative scale (for bars only).
s Make pie chart labels font smaller.
S Make pie chart labels font even more smaller.
SVG report definition string examples (recommended values)
1. If we want to generate top users SVG report for top 10 users only
using pie chart having small label font with legend:
top_users_svg="10psl"
2. If we want to generate top sites SVG report for all sites using pie
chart having smallest label font:
top_sites_svg="pS"
3. If we want to simply switch users grpaphics report to SVG format we
have to supply fake option (this is temporary workaround):
users_graphics_svg="y"
4. If we want to generate server efficiency SVG report using piechar
with legend:
server_efficiency_svg="pl"
USERTAB FILE
The usertab file is used by free-sa to replace visible username or IP
by specified string in reports.
File format
The file consists of lines, each line is original name or IP with
translated string separated by 'space' symbol.
Note: file should end with empty line.
Note: file should be encoded in free-sa locale charset specified by
'locale' option, if it's not defined then runtime locale charset
will be used.
Usertab example
If we want to replace '192.168.0.1' IP with 'Mr. Michael' and
'192.168.0.2' IP with 'Ms. Catarine' then we can make following usertab
file contents:
192.168.0.1 Mr. Michael
192.168.0.2 Ms. Catarine
