An Open Source software that automatically collects system information every 10 seconds

editor's review





collectd is an open source, portable, freely downloadable, easy-to-use, easy to install and reliable command-line software project implemented in plain C as a daemon designed to help users collect system information. It saves the output to a RRD file every 10 seconds.

Gathers data from many hardware components

Thanks to its numerous plugins, collectd gathers data about CPU load, RAM usage, disk usage, as well as network interface usage and DNS traffic. It resides in the memory and uses the /proc-filesystem for reading the information.

Among its features, we can mention SNMP (Simple Network Management Protocol) integration for querying network equipment, as well as a powerful network code that can be used to collect statistics for complete system setups.

Its functionality can be extend

You can easily extend the program’s functionality with plugins. These can written in the C, Perl, Java, Python or UNIX Shell programming languages, or can be execute binaries or scripts. Support for Java MBean is also provided.

When using collectd to collect statistics, please keep in mind that it does not generate graphs and offers a limited monitoring functionality. It has been successfully tested on 32 and 64-bit computer platforms.

Getting started with collectd

To install the collectd software on your personal computer, you will have to first download and save the latest release of the program to your Home directory, extract its contents using an archive manager utility, open a Terminal app and move to the location where you have exracted the archive file (e.g. cd /home/softpedia/collectd-5.4.1).

Then, in the terminal emulator, run the ‘./configure && make’ command to configure (optimize) and compile the program. After a successful compilation process, run the ‘make install’ command as root or the ‘sudo make install’ command as a privileged user to install it system wide and make it available to all users on your machine.
