GoAccess

What is it?

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/

Why GoAccess?

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 report, by default it outputs to a terminal.

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

Installation

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

Briefly, the shell commands ./configure; make; make install should configure, build, and install GoAccess. An INSTALL file is attached within the package for more-detailed instructions.

Usage

The simplest and fastest usage would be:

# goaccess -f access.log

That will generate an interactive text-only output.

To generate an HTML report:

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

To generate full statistics we can run GoAccess as:

# goaccess -f access.log -a

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