Install the ganglia monitoring tool on centos

1. Introduction to ganglia

Ganglia is a distributed monitoring system that has two Daemon: client GangliaMonitoring Daemon (gmond), server GangliaMeta Daemon (gmetad), and GangliaPHP Web

Frontend (web-based Dynamic Access) is a Linux-based software that monitors the running performance of the system. The interface is beautiful and rich, powerful and ganglia relies on a web server to display the cluster status. rrdtool is used to store data and generate graphs. xml parsing is required, so expat is required. libconfuse is required for parsing configuration files.

Ganglia is an open source software for monitoring servers and clusters. It can use graphs to show the cpu load and memory of servers or clusters in the last hour, last day, last week, last month, and last year, network, hard disk, and other indicators.

Ganglia is powerful in that the ganglia server can collect data from all clients in the same network segment through one client, and the ganglia cluster server can collect data from all clients under it through one server. This system design means that a server can manage tens of thousands of machines through different layers. This function is unmatched by other mrtg, nagios, and cacti.
