-	Graphite is real-time graphing system. It is compromised of two components – a webapp frontend and a backend storage application. It allows external application to feed monitoring data into it and then uses it’s “carbon” backend agent to process the data and store it in a specialized graphite database (eg: whisper). The graphite processes need to deployed on the monitoring management box only. Some of the advantages of using Graphite are captured here [2].<br>c) Nagios	+	<br>

	Nagios is a service health check alerting system. It has plugin model that allows service checks to be carried on host groups and generate alerts/notifications in case of any issues detected. The Nagios-Core agent is running on the monitoring management box that provides a webapp frontend and a daemon that reads configurations from it’s resource files and object-definition files. Nagios-NRPE is an addon that allows Nagios to execute plugins on remote hosts.		Nagios is a service health check alerting system.
