GoAccess – A Real-Time Web Server Log Analyzer And Interactive Viewer
|
||
======
|
||
|
||
Analyzing a log file is a big headache for Linux administrators as it’s capturing a lot of things.
|
||
|
||
Most of the newbies and L1 administrators doesn’t know how to analyze this.
|
||
|
||
If you have good knowledge to analyze a logs then you will be a legend for NIX system.
|
||
|
||
There are many tools available in Linux to analyze the logs easily.
|
||
|
||
GoAccess is one of the tool which allow users to analyze web server logs easily.
|
||
|
||
We will be going to discuss in details about GoAccess tool in this article.
|
||
|
||
### What is GoAccess?
|
||
|
||
GoAccess is a real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems or through your browser.
|
||
|
||
GoAccess has minimal requirements, it’s written in C and requires only ncurses.
|
||
|
||
It will support Apache, Nginx and Lighttpd logs. 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 and browser.
|
||
|
||
GoAccess was designed to be a fast, terminal-based log analyzer. Its core idea is to quickly analyze and view web server statistics in real time without needing to use your browser.
|
||
|
||
Terminal output is the default output, it has the capability to generate a complete, self-contained, real-time HTML report, as well as a JSON, and CSV report.
|
||
|
||
GoAccess allows any custom log format and the following (Combined Log Format (XLF/ELF) Apache | Nginx & Common Log Format (CLF) Apache) predefined log format options are included, but not limited to.
|
||
|
||
### GoAccess Features
|
||
|
||
* **`Completely Real Time:`** All the metrics are updated every 200 ms on the terminal and every second on the HTML output.
|
||
* **`Track Application Response Time:`** Track the time taken to serve the request. Extremely useful if you want to track pages that are slowing down your site.
|
||
* **`Visitors:`** Determine the amount of hits, visitors, bandwidth, and metrics for slowest running requests by the hour, or date.
|
||
* **`Metrics per Virtual Host:`** Have multiple Virtual Hosts (Server Blocks)? It features a panel that displays which virtual host is consuming most of the web server resources.
|
||

|
||
### How to Install GoAccess?
|
||
|
||
I would advise users to install GoAccess from distribution official repository with help of Package Manager. It is available in most of the distributions official repository.
|
||
|
||
As we know, we will be getting bit outdated package for standard release distribution and rolling release distributions always include latest package.
|
||
|
||
If you are running the OS with standard release distributions, i would suggest you to check the alternative options such as PPA or Official GoAccess maintainer repository, etc, to get a latest package.
|
||
|
||
For **`Debian/Ubuntu`** systems, use **[APT-GET Command][1]** or **[APT Command][2]** to install GoAccess on your systems.
|
||
|
||
```
|
||
# apt install goaccess
|
||
```
|
||
|
||
To get a latest GoAccess package, use the below GoAccess official repository.
|
||
|
||
```
|
||
$ echo "deb https://deb.goaccess.io/ $(lsb_release -cs) main" | sudo tee -a /etc/apt/sources.list.d/goaccess.list
|
||
$ wget -O - https://deb.goaccess.io/gnugpg.key | sudo apt-key add -
|
||
$ sudo apt-get update
|
||
$ sudo apt-get install goaccess
|
||
```
|
||
|
||
For **`RHEL/CentOS`** systems, use **[YUM Package Manager][3]** to install GoAccess on your systems.
|
||
|
||
```
|
||
# yum install goaccess
|
||
```
|
||
|
||
For **`Fedora`** system, use **[DNF Package Manager][4]** to install GoAccess on your system.
|
||
|
||
```
|
||
# dnf install goaccess
|
||
```
|
||
|
||
For **`ArchLinux/Manjaro`** based systems, use **[Pacman Package Manager][5]** to install GoAccess on your systems.
|
||
|
||
```
|
||
# pacman -S goaccess
|
||
```
|
||
|
||
For **`openSUSE Leap`** system, use **[Zypper Package Manager][6]** to install GoAccess on your system.
|
||
|
||
```
|
||
# zypper install goaccess
|
||
|
||
# zypper ar -f obs://server:http
|
||
|
||
# zypper ref && zypper in goaccess
|
||
```
|
||
|
||
### How to Use GoAccess?
|
||
|
||
After successful installation of GoAccess. Just enter the goaccess command and followed by the web server log location to view it.
|
||
|
||
```
|
||
# goaccess [options] /path/to/Web Server/access.log
|
||
|
||
# goaccess /var/log/apache/2daygeek_access.log
|
||
```
|
||
|
||
When you execute the above command, it will ask you to select the **Log Format Configuration**.

|

|
||
I had tested this with Apache access log. The Apache log is splitted in fifteen section. The details are below. The main section shows the summary about the fifteen section.
|
||
|
||
The below screenshots included four sessions such as Unique Visitors, Requested files, Static Requests, Not found URLs.
|
||
![][9]
|
||
|
||
The below screenshots included four sessions such as Visitor Hostnames and IPs, Operating Systems, Browsers, Time Distribution.
|
||
![][10]
|
||
|
||
The below screenshots included four sessions such as Referrers URLs, Referring Sites, Google’s search engine results, HTTP status codes.
|
||

|
||
|
||
If you would like to generate a html report, use the following format.
|
||
|
||
Initially i got an error when i was trying to generate the html report.
|
||
|
||
```
|
||
# goaccess 2daygeek_access.log -a > report.html
|
||
|
||
GoAccess - version 1.3 - Nov 23 2018 11:28:19
|
||
Config file: No config file used
|
||
|
||
Fatal error has occurred
|
||
Error occurred at: src/parser.c - parse_log - 2764
|
||
No time format was found on your conf file.Parsing... [0] [0/s]
|
||
```
|
||
|
||
It says “No time format was found on your conf file”. To overcome this issue, add the “COMBINED” log format option on it.
|
||
|
||
```
|
||
# goaccess -f 2daygeek_access.log --log-format=COMBINED -o 2daygeek.html
|
||
Parsing...[0,165] [50,165/s]
|
||
```
|
||
|
||
![][12]
|
||
|
||
GoAccess allows you to access and analyze the real-time log filtering and parsing.
|
||
|
||
```
|
||
# tail -f /var/log/apache/2daygeek_access.log | goaccess -
|
||
```
|
||
|
||
For more details navigate to man or help page.
|
||
|
||
```
|
||
# man goaccess
|
||
or
|
||
# goaccess --help
|
