MultiTail: Monitor Multiple Logs in One Shell | Linux

Monitoring Multiple Log Files with MultiTail on Linux

For system administrators and developers alike, the need to track several log files simultaneously is a common occurrence. Managing numerous shell windows can become cumbersome. Fortunately, Linux provides a valuable tool called MultiTail, designed to monitor multiple logs within a single window.

Installation Process

The initial step involves downloading and extracting the source code. Utilize the following command, remembering to adjust the version number as needed for the latest release:

wget http://www.vanheusden.com/multitail/multitail-5.2.0.tgz tar xvfz multitail-5.2.0.tgz

After extraction, navigate into the newly created directory and execute "make install" to compile and install the application. Root privileges are required for installation, which can be achieved using sudo:

cd multitail-5.2.0 sudo make install

Upon completion, MultiTail is fully installed and accessible to all users, typically located in /usr/bin/multitail.

Utilizing MultiTail

To combine log files into a horizontally divided window, employ the -i flag preceding each log file name. This approach is particularly beneficial when dealing with limited screen space or files containing lengthy lines.

multitail -i error_log -i access_log

Furthermore, the -l flag enables the display of command output, such as ping or traceroute results. This functionality extends to incorporating scripts that filter specific output, focusing on relevant information like error messages.

multitail -l "ping www.howtogeek.com" -l "ping blogs.howtogeek.com"

MultiTail offers a wealth of additional features. These include customizable color schemes, vertical splitting options, and the ability to view log file statistics.
