What are some features that make colleclt a useful tool?įollowing are some of the most important features of the collectl command-line utility for you guys. Unlike most of the other monitoring tools, collectl does not focus on a limited number of system metrics, instead, it can gather information on many different types of system resources such as cpu, disk, memory, network, sockets, tcp, inodes, infiniband, cluster, memory, nfs, processes, quadrics, slabs, and buddyinfo.Ī very good thing about using collectl is that it can also play the role of utilities that are designed with only a specific purpose such as top, ps, iotop, and many others. Collectl – Linux System Performance MonitoringĬollectl is a very nice feature-rich command-line utility that can be used to collect performance data that describes the current system status. There are many tools available for Linux system admins that can help to monitor and display processes in a system such as top and htop, but none of these tools can compete with collectl. 
The most important duty of a Linux system administrator is to make sure the system he/she is administering is in very good condition.
