Mytop is an open source, command line tool used for monitoring MySQL performance. It was inspired by the Linux system monitoring tool named top and is similar to it in look and feel. Mytop connects to a MySQL server and summarizes the information in a useful format. Using mytop, we can monitor (in real-time) MySQL threads, queries, and uptime as well as see which user is running queries on which database, which are the slow queries, and more.

In this article we will be looking at enhancing system security by increasing the level of monitoring performed. We are going to set up Linux Socket Monitor (LSM) which sends out alerts when a new socket / port is created, which is a potential signal of an intrusion by an unknown application taking over its host.
In this tutorial we will show you how to install and configure Graphite – a tool for storing numeric time-series data and rendering graphs of this data. It consists of three software components:
Checkmk is a monitoring solution that is both robust and simpler to install than many of its competitors. It is a self-contained software bundle that combines Nagios (a popular and open-source alerting service) with add-ons for gathering, monitoring, and graphing data. It also comes with Checkmk’s web interface — a comprehensive tool that addresses many of Nagios’s shortcomings. In this guide we will set up Checkmk and monitor two separate hosts: an Ubuntu 18.04 server and a CentOS 7 server.
