NAME
calamaris - generate text and graphical statistics out of log files from Proxy-Cache-Servers
SYNOPSIS
cat log | calamaris [ --config-file .../calamaris.conf ] [ switches ]
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 with or without graphic and with or without frames. 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
Configuration File
--config-file file
Not all reports and modification can be made through command-line-switches. To use all options of
Calamaris you´ll have to use the configuration file. You'll find the configuration-directives
below, always inside of braces. Examples are in the calamaris.conf which should come with this
package.
Reports
--all-useful-reports|-a
extracts all useful reports available, --all-useful-reports equals --size-distribution-report 10
--domain-report 20 --performance-report 60 --requester-report 20 --status-report --type-report 20
--response-time-report --errorcode-distribution-report
--domain-report|-d n ($domain_report)
switches the top level and the second level report on. The data is derived from the URL. The
output is limited by n. (-1 is unlimited)
--domain-report-limit n ($domain_report_limit)
limit the domain-report to lines which have n or more requests.
--domain-report-n-level|-N n ($domain_report_n_level)
All URL-Host reports will be switched from 2nd-level to n-level-reports. (-1 shows a full urlhost-
report)
Note: This option is only useful with activated domain-report.
--errorcode-distribution-report ($errorcode_distribution_report)
shows the Response code distribution over all objects
($object_freshness_report)
shows the freshness of objects in your cache. Calamaris looks for freshness tags like 'TCP_HIT',
'TCP_REFRESH_MISS', ... and make statistics on it. With this information you can optimize the
caching behaviour of your cache depending on the objects content type. E.g. squid admins could
use this information to configure the refresh_pattern. This option needs more configuration in the
configuration-file.
--peak-report|-p type ($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 calculated with the old
slow method, if set to 'new' the new faster (but still slow) method is used.
--performance-report|-P n ($performance_report)
Shows the throughput of TCP requests for every n minutes.
--performance-report-adjust|-T n ($performance_report_adjust)
Time: Adjust the Performancereport in minutes for non GMT-Timezoners.
--requester-report|-r n ($requester_report)
Switches the UDP and TCP requester reports on. The output is limited by n. (-1 is unlimited)
--requester-report-no-dns-lookup|-n ($requester_report_no_dns_lookup)
Switches the IP lookup for the requesters off.
--requester-report-use-user-info|-u ($requester_report_use_user_info)
Switches the usage of eventually available ident information for requester reports on.
Warning: This breaks the privacy of your users! (see PRIVACY-Section below)
--requester-report-with-targets|-R n ($requester_report_with_targets)
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)
--response-time-report ($response_time_report)
sums up the time distribution over all objects
(@response_time_report_interval)
This array defines the time steps, which should be reported in the response-time-report.
--size-distribution-report|-D n ($size_distribution_report)
shows size-based distribution of requested objects, smaller numbers result in more verbose
reports. (choose 2, 10 or 100 for useful output.)
--status-report|-s ($status_report)
alters the default behaviour of Calamaris and makes the status reports more verbose.
--type-report|-t n ($type_report)
switches the content type and the file extension report on. The output is limited by n. (-1 is
unlimited)
--type-report-ignore-case|-c ($type_report_ignore_case)
Switch to case-insensitive. This is useful for the 'Requested extensions' report.
Input
--input-format|-f type ($input_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, Calamaris 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 Netscape Extended-2 Logfile Format
(from Netscape/iPlanet/SunOne Proxy-Server )
--ipfilter-exclude IP/range ($ipfilter_exclude)
all IPs are analyzed, except IP/range. Format: 1.1.1.1/32:1.1.2.0/24 or
1.1.1.1/255.255.255.255:1.1.2.0/255.255.255.0
IP list separated by ':' This switch needs the perl Module NetAddr::IP.
Warning: This breaks the privacy of your users! (see PRIVACY-Section below)
--ipfilter-include IP/range ($ipfilter_include)
no IPs are analyzed, except IP/range. Format: see --ipfilter-exclude
Warning: This breaks the privacy of your users! (see PRIVACY-Section below)
--no-input|-z ($no_input)
Switches reading from standard input off. You can use this to merge many cache files to one (see
--cache-input-file and --cache-output-file) or to generate a report out of cache files.
--time-interval|-I t-t ($time_interval)
defines which time-interval should be parsed. t has to be the format yyyymmddhhmmss (localtime)
Note: omitting the beginning or ending date is allowed.
Output
Standard output format is plain ascii with 80 chars width.
($column1_color)
($column2_color) defines the colors for the columns in graphics. (only useful with --output-format
graph)
($formats[n])
Through the config-file you are able to modify the width of the report and alter the culomns that
are displayed in the reports. n is the number of the report, as displayed by --help in the --show-
reports-option.
--hostname|-H name ($hostname)
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.
--image-type ($image_type)
Sets the image type to gif, png, jpeg, gd or gd2. Only useful when --output-format graph is set.
The available images types are dependend on your GD::Graph installation. Default is 'png'.
--logo|-l string ($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: --logo works only in combination with --output-format html or html-frame
--meta|-M string ($meta)
Meta: adds a custom string or the content of a file into the <HEAD> of a HTML-Report. Useful if
you want to add Stylesheets or something to the Report.
Note: --meta works only in combination with --output-format html or html-frame
--output-format|-F type[,type[,type[,...]]] ($output_format)
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-frame' all output is given in html frames with tables.
'html-embed' all output is given in html with tables without HTML-Headers. Useful for Server-Side-
Includes.
'graph' enables graphics for html, html-embed or html-frame.
'unformatted' gives out the raw numbers separated 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.
--output-path ($output_path)
output calamaris statistics to /path. In case of graph output, the graphics destination is /path
and the filename is index.html, else it is calamaris.txt. If --output-path is not given, all
graphics are written to the working directory.
--output-file ($output_file)
alter the filename of --output-path.
--output-file-prefix ($output_file_prefix)
adds a prefix to --output-file %t is replaced by the timerange of the report, %h by the hostname
(see --hostname )
--show-reports|-S n[,n[,n[,...]]] ($show_reports)
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 peak 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 Size Distribution Diagram
16 Performance in n minute steps
17 UDP-Request duration distribution in msec
18 TCP-Request duration distribution in msec
19 UDP Response code distribution
20 TCP Response code distribution
Note: Using this doesn't make Calamaris any faster, the internal calculations will be done as the report-
switches were set (see above).
--sort-order|-O ($sort_order)
Changes the sort order in the reports to request size, default is sorting by number of requests.
($text_color)
defines the colors for text/axis/legend/labels in graphics. (only useful with --output-format
graph )
--unit|-U string ($unit)
You can define this to K(ilo), M(ega), G(iga) or T(era) for the Byte-units.
($width)
defines the width of the graphics. height is calculated from this with a 3:2-ratio. (only useful
with --output-format graph )
($x_scale)
defines how many datasets should be drawn on the graph. 30 is a good value, but you can play with
this. if $x_scale gets to big, you're on your own ;-)
--generate-index ($generate_index)
generates an index for all reports that match --output-file-prefix.
Caching
--cache-input-file|-i file ($cache_input_file)
You can reuse a cache file generated with --cache-output-file file to add old data to a new
report. Several files can be separated with a ':'.
Note: if you use more than one cache file, make sure they are chronologicaly ordered (oldest
first).
Note: if you reuse cache-files, which were not created with -d -1 -r -1 -t -1 -R -1 the number of
'others' would be wrong everywhere. In this case the number of 'others' are omitted.
--cache-output-file|-o file ($cache_output_file)
Calamaris stores a summary of the computed information in file and you can reuse it at a later
time with --cache-input-file
Note: The output file can be the same as the input file: it is simply overwritten after reading
the data. It is not recommended to change the options between different runs if you include older
data as this can result in strange measurements.
Misc
--benchmark|-b n ($benchmark)
benchmark: A switch for the impatient as it prints a '#' for every n parsed lines.
--copyright|-C
Prints the copyright information of Calamaris
--help|-h
Prints a brief description of the command line options.
--version|-V
Prints out the Version-Number.
Debug
--dump-loop|-L
prints the internal loop to STDERR. (for Debugging)
($test)
activates some small tests for the programmer.
--verbose|-v ($verbose)
print more information about what is Calamaris is doing and believing.
EXAMPLES
This example mails the daily statistics to root:
cat /var/log/squid/access.log | nice -39 calamaris --all-useful-reports --hostname "daily worf"
--output-format mail | mail root
This one only caches a summary for later use:
cat /var/log/squid/access.log | calamaris --all-useful-reports --cache-output-file daily.`date
+"%w"` > /dev/null
You can then use the caches to have weekly statistics:
if [ $DAYOFWEEK = "0" ]; then
calamaris --all-useful-reports --cache-input-file
daily.1:daily.2:daily.3:daily.4:daily.5:daily.6:daily.0 --no-input --output-format mail --hostname
"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!)
