CALAMARIS(1) Calamaris Manual CALAMARIS(1)NAMEcalamaris - generate statistic out of log files from Proxy-Cache-
Servers
SYNOPSIS
cat log | calamaris [ calamaris_options ]
DESCRIPTION
Calamaris is used to produce statistical output from Squid, NetCache,
Inktomi Traffic Server, Oops! proxy server, Compaq Tasksmart, Cisco
Content Engines or related Proxy log files. The resulting output can
be ascii or html. It is possible to cache calculated data in a file to
use them in later runs.
This manual page describes the options of Calamaris and gives a few
examples.
OPTIONS
Reports
-a all: extracts all reports available, -a equals -D 10 -d 20 -P 60
-r 20 -s -t 20.
-d n domain report: switches the top level and the second level
report on. The data is derived from the URL. The output is
limited by n. (-1 is unlimited)
-p type
peak report: Measures the peaks of the Proxy usage in requests
per second, per minute and per hour. It reports peaks for TCP,
UDP and ALL requests. If set to 'old' these values were calcu‐
lated with the old slow method, if set to 'new' the new faster
(but still slow) method is used.
-P n performance report: Shows the throughput of TCP requests for
every n minutes.
-r n requester report: Switches the UDP and TCP requester reports on.
The output is limited by n. (-1 is unlimited)
-R n Requested report: adds to each line of the requester report the
requested URLs. The output is limited by n. (-1 is unlimited,
and can result in very very long reports.)
Warning: Using this option breaks the privacy of your users!
(see PRIVACY-Section below)
-s status report: alters the default behaviour of Calamaris and
makes the status reports more verbose.
-t n type report: switches the content type and the file extension
report on. The output is limited by n. (-1 is unlimited)
-D n Distribution Histogram: shows size-based distribution of
requested objects, smaller numbers result in more verbose
reports. (choose 2, 10 or 100 for useful output.)
Allocation report: shows how different sized objects perform on
your Proxy.
Input Format
-f type
format: sets the type of input logfiles. If set to
'auto' Calamaris tries to guess the input file format. This is
the Default.
Note: If the first line of your input file is corrupted, Cala‐
maris will stop with an error.
'squid' Calamaris expects native logfile derived from Squid
V1.1.beta26-V2.x or OOPS.
'squid-extended' Calamaris expects native logfile derived from
Squid V1.1.alpha1-V2.x with log_mime_hdrs enabled or Squid with
Smartfilter-Patch. or squid-style logfiles out of Cisco Content
Engines. (This only enables parsing of these kind of logfile,
the additional data will be ignored.)
(Logging of MIME-Headers breaks the privacy of your users! (see
PRIVACY-Section below)
'squid-old' Calamaris expects native logfile derived from Squid
V1.1.alpha1-V1.1.beta25.
'nc' Calamaris expects Logfiles from NetCache up to V4.x.
(Please see the README on this.)
'its' Calamaris expects Logfiles from Inktomi Traffic Server.
'elff' Calamaris expects Logfiles in Extended Logfile Format
(i.e. from Compaq Tasksmart, Novell Internet Caching System or
NetCache V5.x )
'nse' Calamaris expects Logfiles in Netscape Extended-1 or Net‐
scape Extended-2 Logfile Format (from Netscape/ipoint Proxy-
Server )
Output Format
Standard output format is plain ascii with 80 chars width.
-F type[,type[,type[,...]]]
Format: sets the format of the output-report. If set to
'mail' adds a subject header to the beginning of the report.
'html' all output is given in html with tables. Can be combined
with 'mail' to send html mails.
'html-embed' all output is given in html with tables without
HTML-Headers. Useful for Server-Side-Includes.
'unformatted' gives out the raw numbers seperated by spaces.
Useful for re-using the output in other scripts. If you use this
along with -U, the byte values are calculated in the given Unit,
and displayed without indication along with the numbers. the
indication moves up to the header of the report.
-M string
Meta: adds a custom string into the <HEAD> of a HTML-Report.
Useful if you want to add Stylesheets or something to the
Report.
Note: -M works only in combination with -F html.
-l string
logo: add a custom string to a HTML-Report. It'll be added to a
table on the top of the output. -l '<A
HREF="http://cord.de/"><IMG BORDER=0
SRC="http://cord.de/Images/cord/cordlog2n.gif" ALT="Cord"></A>'
will add my logo with a link to the Report.
Note: -l works only in combination with -F html.
-U string
Unit: You can define this to K(ilo), M(ega), G(iga) or T(era)
for the Byte-units.
-S n[,n[,n[,...]]]
Show: Shows only the defined reports in the specified order.
Default is to display the reports as they are defined through
the report-switches above. The following numbers are defined:
0 Summary
1 Incoming request peak per protocol
2 Incoming transfer volume per protocol
3 Incoming requests by method
4 Incoming UDP-requests by status
5 Incoming TCP-requests by status
6 Outgoing requests by status
7 Outgoing requests by destination
8 Request-destinations by 2ndlevel-domain
9 Request-destinations by toplevel-domain
10 TCP-Request-protocol
11 Requested content-type
12 Requested extensions
13 Incoming UDP-requests by host
14 Incoming TCP-requests by host
15 Distribution Histogram
16 Performance in minute steps
Note: Using this doesn't make Calamaris any faster, the internal
calculations will be done as the report-switches were set (see
above).
Caching
-i file
input file: You can reuse a cache file generated with -o file to
add old data to a new report. Several files can be seperated
with a ':'.
Note: if you use more than one cache file, make sure they are
chronologicaly ordered (oldest first).
Note: if you reuse cache-files, which were not created with -d
-1-r-1-t-1-R -1 the number of 'others' is likely wrong
everywhere.
-o file
output file: Calamaris stores a summary of the computed informa‐
tion in file and you can reuse it at a later time with -i.
Note: The output file can be the same as the input file: it is
simply overwritten after reading the data. It is not recom‐
mended to change the options between different runs if you
include older data as this can result in strange measurements.
Misc
-H name
Host name: The name for the title or subject of the output. If
set to 'lookup' Calamaris looks up the host name of the system
its been run on.
-n no lookup: Switches the IP lookup for the requesters off.
-O Order: Changes the sort order in the reports to request size,
default is sorting by number of requests.
-I t-t Interval: defines which time-interval should be parsed. t has
to be the format yyyymmddhhmmss
Note: omitting the beginning or ending date is allowed.
-N N-level: All URL-Host reports will be switched from 2nd-level to
N-level-reports. (-1 shows a full urlhost-report)
Note: This option is only useful with activated domain-report.
-T n Time: Adjust the Performancereport in minutes for non GMT-Time‐
zoners.
-c case: Switch to case-insensitive. This is useful for the
'Requested extensions' report.
-u user: Switches the usage of eventually available ident informa‐
tion for requester reports on.
Warning: This breaks the privacy of your users! (see PRIVACY-
Section below)
-z zero: Switches reading from standard input off. You can use
this to merge many cache files to one (see -i and -o) or to gen‐
erate a report out of cache files.
-b n benchmark: A switch for the impatient as it prints a '#' for
every n parsed lines.
-v verbose: print more information about what is Calamaris is doing
and believing.
-L Loop: prints the internal loop to STDERR. (for Debugging)
-C Copyright: Prints the copyright information of Calamaris.
-h help: Prints a brief description of the command line options.
-V Version: Prints out the Version-Number.
EXAMPLES
This example mails the daily statistics to root:
cat /var/log/squid/access.log | nice -39calamaris-aH 'daily
worf' -F mail | mail root
This one only caches a summary for later use:
cat /var/log/squid/access.log | calamaris-a-o daily.`date
+"%w"` > /dev/null
You can then use the caches to have weekly statistics:
if [ $DAYOFWEEK = "0" ]; then calamaris-a-i
daily.1:daily.2:daily.3:daily.4:daily.5:daily.6:daily.0 -z-F
mail -H "weekly worf" | mail root ; fi
BUGS
If you have a problem with Calamaris, please make sure that you use the
recent version of Calamaris (see VERSION below). Also check that your
proxy works correctly and doesn't produce invalid Logfiles. (see the
README for buglist and pointers.)
If you're sure that you've encountered a bug in Calamaris, please
report it to Calamaris-bug@cord.de. This also applies if Calamaris
itself says 'please report this'.
PRIVACY
Calamaris can be (mis-)used to track what users are requesting.
So please read the following and think about it, before using Calamaris
to be the Big Brother.
- If you don't trust your users than there is something more wrong
than the loss of productivity.
- Squid has some nice acl-mechanisms. If you think that your users
don't use the net properly, don't let them use it. (You can also
open the net at specific times or to specific sites, if you
want.)
- If you still want to use Calamaris that way, let your
vict^Wusers know, that they'll be monitored. (in Germany you
have to let them know!)
