GoAccess is an open source real-time web log analyzer and interactive viewer that *runs in a terminal in nix systems. It provides fast and valuable HTTP statistics for system administrators that require a visual server report on the fly. More info at: http://goaccess.prosoftcorp.com.

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

• General Statistics, bandwidth, etc.
• Time taken to serve the request (useful to track pages that are slowing down your site)
• Top Visitors
• Requested files
• Requested static files, images, swf, js, etc.
• 404 or Not Found
• Hosts, Reverse DNS, IP Location
• Operating Systems
• Browsers and Spiders
• Referring Sites
• Referrers URLs
• Keyphrases
• Geo Location - Continents/Countries
• HTTP Status Codes
• Ability to output JSON and CSV
• Different Color Schemes
• Support for IPv6
• Output statistics to HTML. See report.

GoAccess allows any custom log format string. Predefined options include, but not limited to:

• Common Log Format (CLF) Apache
• Combined Log Format (XLF/ELF) Apache | Nginx
• W3C format (IIS).
• Amazon CloudFront (Download Distribution).
• Apache virtual hosts

The main idea behind GoAccess is being able to quickly analyze and view web server statistics in real time without having to generate an HTML report. Although it is possible to generate an HTML, JSON, CSV report, by default it outputs to a terminal.

You can see it more as a monitor command tool than anything else.

GoAccess can be compiled and used on Linux, OSX, OpenBSD, NetBSD, FreeBSD.

Download, extract and compile GoAccess with:

$ wget http://downloads.sourceforge.net/project/goaccess/0.7.1/goaccess-0.7.1.tar.gz
$ tar -xzvf goaccess-0.7.1.tar.gz
$ cd goaccess-0.7.1/
$ ./configure --enable-geoip --enable-utf8 
$ make
# make install

$ git clone https://github.com/allinurl/goaccess.git 
$ cd goaccess 
$ autoreconf -fi 
$ ./configure --enable-geoip --enable-utf8 
$ make
# make install

The simplest and fastest usage would be:

# goaccess -f access.log

That will generate an interactive text-only output.

To generate full statistics we can run GoAccess as:

# goaccess -f access.log -a

To generate an HTML report:

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

To generate a JSON file:

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

To generate a CSV file:

# goaccess -f access.log -o csv > report.csv

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

The -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.)

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

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:

# zcat access.log.*.gz | goaccess 
OR
# zcat -f access.log* | goaccess

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 '/05\/Dec\/2010/,$ p' 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
