Basic Linux Systems Monitoring Tools for System Admininstrators

How important is monitoring tools for our IT infrastructure? The best way to ensure a healthy infrastructure is through systems monitoring tools in order to verify performance and resources, act on alerts as well as planning for future improvements and upgrades. Let’s look at Linux monitoring tools for systems administrators:


Usage:                  To monitor multiprocessor usage in Linux.

Command:          sudo mpstat



Usage:                  Tcpdump is a packet analyzer that allows a user to display TCP/IP and other packets being transferred over the network.
