NAME
goaccess - fast web log analyzer and interactive viewer.

SYNOPSIS

goaccess [-f input-file][-c][-r][-d][-m][-q][-o][-h][...]

DESCRIPTION
goaccess GoAccess is an open source real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems or through your browser.

It provides fast and valuable HTTP statistics for system administrators that require a visual server report on the fly.

GoAccess parses the specified web log file and outputs the data to the X terminal. Features include:

General Statistics:
    This panel gives a summary of several metrics, some of them are: number of valid and invalid requests, time taken to analyze the data set, unique visitors, requested files, static files (CSS, ICO, JPG, etc) HTTP referrers, 404s, size of the parsed log file and bandwidth consumption.

Unique visitors
    This panel shows metrics such as hits, unique visitors and cumulative bandwidth per date. HTTP requests containing the same IP, the same date, and the same user agent are considered a unique visitor. By default, it includes web crawlers/spiders.

    Optionally, date specificity can be set to the hour level using --date-spec=hr which will display dates such as 05/Jun/2016:16. This is great if you want to track your daily traffic at the hour level.

Requested files
    This panel displays the most highly requested files on your web server. It shows hits, unique visitors, and percentage, along with the cumulative bandwidth, protocol, and the request method used.

Requested static files
    Lists the most frequently static files such as: JPG, CSS, SWF, JS, GIF, and PNG file types, along with the same metrics as the last panel. Additional static files can be added to the configuration file.

404 or Not Found
    Displays the same metrics as the previous request panels, however, its data contains all pages that were not found on the server, or commonly known as 404 status code.

Hosts
    This panel has detailed information on the hosts themselves. This is great for spotting aggressive crawlers and identifying who's eating your bandwidth. Expanding the panel can display more information such as host's reverse DNS lookup result, country of origin and city. If the -a argument is enabled, a list of user agents can be displayed by selecting the desired IP address, and then pressing ENTER.

Operating Systems
    This panel will report which operating system the host used when it hit the server. It attempts to provide the most specific version of each operating system.

Browsers
    This panel will report which browser the host used when it hit the server. It attempts to provide the most specific version of each browser.

Visit Times
    This panel will display an hourly report. This option displays 24 data points, one for each hour of the day.

    Optionally, hour specificity can be set to the tenth of a minute level using --hour-spec=min which will display hours as 16:4 This is great if you want to spot peaks of traffic on your server.

Virtual Hosts
    This panel will display all the different virtual hosts parsed from the access log. This panel is displayed if %v is used within the log-format string.

Referrers URLs
    If the host in question accessed the site via another resource, or was linked/diverted to you from another host, the URL they were referred from will be provided in this panel. See `--ignore-panel` in your configuration file to enable it. disabled by default.

Referring Sites
    This panel will display only the host part but not the whole URL. The URL where the request came from.

Keyphrases
    It reports keyphrases used on Google search, Google cache, and Google translate that have lead to your web server. At present, it only supports Google search queries via HTTP. See `--ignore-panel` in your configuration file to enable it. disabled by default.

Geo Location
    Determines where an IP address is geographically located. Statistics are broken down by continent and country. It needs to be compiled with GeoLocation support.

HTTP Status Codes
    The values of the numeric status code to HTTP requests.

NOTE: Optionally and if configured, all panels can display the average time taken to serve the request.

STORAGE

There are three storage options that can be used with GoAccess. Choosing one will depend on your environment and needs.

Default Hash Tables
    In-memory storage provides better performance at the cost of limiting the dataset size to the amount of available physical memory. By default GoAccess uses in-memory hash tables. If your dataset can fit in memory, then this will perform fine. It has very good memory usage and pretty good performance.

Tokyo Cabinet On-Disk B+ Tree
    Use this storage method for large datasets where it is not possible to fit everything in memory. The B+ tree database is slower than any of the hash databases since data has to be committed to disk. However, using an SSD greatly increases the performance. You may also use this storage method if you need data persistence to quickly load statistics at a later date.

Tokyo Cabinet In-memory Hash Database
    An alternative to the default hash tables. It uses generic typing and thus it's performance in terms of memory and speed is average.

CONFIGURATION

Multiple options can be used to configure GoAccess. For a complete up-to-date list of configure options, run ./configure --help

--enable-debug
    Compile with debugging symbols and turn off compiler optimizations.

--enable-utf8
    Compile with wide character support. Ncursesw is required.

--enable-geoip
    Compile with GeoLocation support. MaxMind's GeoIP is required.

--enable-tcb=<memhash|btree>
    Compile with Tokyo Cabinet storage support. memhash will utilize Tokyo Cabinet's on-memory hash database. btree will utilize Tokyo Cabinet's on-disk B+ Tree database.

--disable-zlib
    Disable zlib compression on B+ Tree database.

--disable-bzip
    Disable bzip2 compression on B+ Tree database.

--with-getline
    Use GNU getline() to parse full line requests instead of a fixed size buffer of 4096.

OPTIONS

The following options can be supplied to the command or specified in the configuration file. If specified in the configuration file, long options need to be used without prepending --.

--time-format=<timeformat>
    The time-format variable followed by a space, specifies the log format time containing either a name of a predefined format (see options below) or any combination of regular characters and special format specifiers.

    They all begin with a percentage (%) sign. See `man strftime`. %T or %H:%M:%S.

    Note that if a timestamp is given in microseconds, %f must be used as time-format

--date-format=<dateformat>
    The date-format variable followed by a space, specifies the log format time containing either a name of a predefined format (see options below) or any combination of regular characters and special format specifiers.

    They all begin with a percentage (%) sign. See `man strftime`. %Y-%m-%d.

    Note that if a timestamp is given in microseconds, %f must be used as date-format

--log-format=<logformat>
    The log-format variable followed by a space or \\t for tab-delimited, specifies the log format string. Note that if there are spaces within the format, the string needs to be enclosed in single/double quotes. Inner quotes need to be escaped.

    In addition to specifying the raw log/date/time formats, for simplicity, any of the following predefined log format names can be supplied to the log/date/time-format variables. GoAccess can also handle one predefined name in one variable and another predefined name in another variable.

      COMBINED - Combined Log Format,
      VCOMBINED - Combined Log Format with Virtual Host,

    Specifies the number of elements of the bucket array. If it is not more than 0, the default value is specified. The default value is 32749. Suggested size of the bucket array is about from 1 to 4 times of the number of all pages to be stored. Only if configured with --enable-tcb=btree

--compression=<zlib|bz2>
    Specifies that each page is compressed with ZLIB|BZ2 encoding. Only if configured with --enable-tcb=btree

CUSTOM LOG/DATE FORMAT
GoAccess can parse virtually any web log format.

Predefined options include, Common Log Format (CLF), Combined Log Format (XLF/ELF), including virtual host, Amazon CloudFront (Download Distribution), Google Cloud Storage and W3C format (IIS).

GoAccess allows any custom format string as well.

There are two ways to configure the log format. The easiest is to run GoAccess with -c to prompt a configuration window. Otherwise, it can be configured under ~/.goaccessrc or the %sysconfdir%.

time-format
    The time-format variable followed by a space, specifies the log format time containing any combination of regular characters and special format specifiers. They all begin with a percentage (%) sign. See `man strftime`. %T or %H:%M:%S.

    Note: If a timestamp is given in microseconds, %f must be used as time-format

date-format
    The date-format variable followed by a space, specifies the log format date containing any combination of regular characters and special format specifiers. They all begin with a percentage (%) sign. See `man strftime`. e.g., %Y-%m-%d.

    Note: If a timestamp is given in microseconds, %f must be used as date-format

log-format
    The log-format variable followed by a space or \\t , specifies the log format string.

%x  A date and time field matching the time-format and date-format variables. This is used when a timestamp is given instead of the date and time being in two separated variables.

%t  time field matching the time-format variable.

%d  date field matching the date-format variable.

%v  The canonical Server Name of the server serving the request (Virtual Host).

%h  host (the client IP address, either IPv4 or IPv6)

%r  The request line from the client. This requires specific delimiters around the request (as single quotes, double quotes, or anything else) to be parsable. If not, we have to use a combination of special format specifiers as %m %U %H.

%q  The query string.

%m  The request method.

%U  The URL path requested. Note: If the query string is in %U, there is no need to use %q. However, if the URL path, does not include any query string, you may use %q and the query string will be appended to the request.

%H  The request protocol.

%s  The status code that the server sends back to the client.

%b  The size of the object returned to the client.

%R  The "Referrer" HTTP request header.

%u  The user-agent HTTP request header.

%D  The time taken to serve the request, in microseconds as a decimal number.

%T  The time taken to serve the request, in seconds with milliseconds resolution.

%L  The time taken to serve the request, in milliseconds as a decimal number.

    Note: If multiple time served specifiers are used at the same time, the first option specified in the format string will take priority over the other specifiers.

%^  Ignore this field.

%~  Move forward through the log string until a non-space (!isspace) char is found.

GoAccess requires the following fields:

    %h a valid IPv4/6

    %d a valid date

    %r the request

EXAMPLES

  DIFFERENT OUTPUTS

To output to a terminal and generate an interactive report:

    # goaccess -f access.log

To generate an HTML report:

    # goaccess -f access.log -a -o report.html

To generate a JSON report:

    # goaccess -f access.log -a -d -o report.json

To generate a CSV file:

    # goaccess -f access.log --no-csv-summary -o report.csv

•   -a flag indicates that we want to process an agent-list for every host parsed.

•   -d flag indicates that we want to enable the IP resolver on the HTML|JSON output. (It will take longer time to output since it has to resolve all queries)

•   -c flag will prompt the date and log format configuration window. Only when curses is initialized.

  REAL TIME HTML OUTPUT

GoAccess has the ability the output real-time data in the HTML report. You can even email the HTML file since it is composed of a single file with no external file dependencies, how neat is that!

To output an HTML report and set the WebSocket server to listen on port 7890 and localhost.

    # goaccess -f access.log -o report.html --real-time-html

If GoAccess is running on a specific host, you can specify the URL to which to connect.

    # goaccess -f access.log -o report.html --real-time-html --ws-url=goaccess.io

To use a different port other than 7890, you can specify it as:

    # goaccess -f access.log -o report.html --real-time-html --ws-url=goaccess.io --port=9870

And to bind the WebSocket server to a different interface other than 0.0.0.0, you can specify it as:

    # goaccess -f access.log -o report.html --real-time-html --ws-url=goaccess.io --addr=127.0.0.1

  MULTIPLE LOG FILES

Now if we want to add more flexibility to GoAccess, we can do a series of pipes. For instance:

If we would like to process all access.log.*.gz we can do one of the following:

    # zcat -f access.log* | goaccess

    # zcat access.log.*.gz | goaccess

Note: On Mac OS X, use gunzip -c instead of zcat.

  WORKING WITH DATES

Another useful pipe would be filtering dates out of the web log

The following will get all HTTP requests starting on 05/Dec/2010 until the end of the file.

    # sed -n '/05Dec2010/,$ p' access.log | goaccess -a

or using relative dates such as yesterdays or tomorrows day:

    # sed -n '/'$(date '+%d%b%Y' -d '1 week ago')'/,$ p' access.log | goaccess -a

If we want to parse only a certain time-frame from DATE a to DATE b, we can do:

    # sed -n '/5Nov2010/,/5Dec2010/ p' access.log | goaccess -a

  VIRTUAL HOSTS

Assuming your log contains the virtual host field. For instance:

    vhost.com:80 10.131.40.139 - - [02/Mar/2016:08:14:04 -0600] "GET /shop/bag-p-20 HTTP/1.1" 200 6715 "-" "Apache (internal dummy connection)"

And you would like to append the virtual host to the request in order to see which virtual host the top urls belong to

    awk '$8=$1$8' access.log | goaccess -a

To exclude a list of virtual hosts you can do the following:

    # grep -v "`cat exclude_vhost_list_file`" vhost_access.log | goaccess

  FILES & STATUS CODES

To parse specific pages, e.g., page views, html, htm, php, etc. within a request:

    # awk '$7~/.html|.htm|.php/' access.log | goaccess

Note, $7 is the request field for the common and combined log format, (without Virtual Host), if your log includes Virtual Host, then you probably want to use $8 instead. It's best to check which field you are shooting for, e.g.:

    # tail -10 access.log | awk '{print $8}'

Or to parse a specific status code, e.g., 500 (Internal Server Error):

    # awk '$9~/500/' access.log | goaccess

  SERVER

Also, it is worth pointing out that if we want to run GoAccess at lower priority, we can run it as:

    # nice -n 19 goaccess -f access.log -a

and if you don't want to install it on your server, you can still run it from your local machine:

    # ssh root@server 'cat /var/log/apache2/access.log' | goaccess -a

  INCREMENTAL LOG PROCESSING

GoAccess has the ability to process logs incrementally through the on-disk B+Tree database. It works in the following way:

    A data set must be persisted first with --keep-db-files, then the same data set can be loaded with --load-from-disk.

    If new data is passed (piped or through a log file), it will append it to the original data set.

    To preserve the data at all times, --keep-db-files must be used.

    If --load-from-disk is used without --keep-db-files, database files will be deleted upon closing the program.

For instance:

    // last month access log
    goaccess -f access.log.1 --keep-db-files

then, load it with

    // append this month access log, and preserve new data
    goaccess -f access.log --load-from-disk --keep-db-files

To read persisted data only (without parsing new data)

    goaccess --load-from-disk --keep-db-files

NOTES
Each active panel has a total of 366 items or 50 in the real-time HTML report. The number of items is customizable using max-items However, only the CSV and JSON output allow a maximum number greater than the default value of 366 items per panel.

Piping a log to GoAccess will disable the real-time functionality. This is due to the portability issue on determining the actual size of STDIN. However, a future release *might* include this feature.

A hit is a request (line in the access log), e.g., 10 requests = 10 hits. HTTP requests with the same IP, date, and user agent are considered a unique visit.
