Monitoring Resource Utilization with Cacti on Ubuntu 10.04 (Lucid) – Linode Library

Monitoring Resource Utilization with Cacti on Ubuntu 10.04 (Lucid) – Linode Library:

The Linode Manager provides some basic monitoring of system resource utilization, which includes information regarding Network, CPU, and Input/Output usage over the last 24 hours and 30 days. While this basic information is helpful for monitoring your system, there are cases where more fine-grained information is useful. The simple monitoring tool Munin is capable of monitoring needs of a small group of machines. In some cases, Munin may not be flexible enough for advanced monitoring needs.
For these kinds of deployments we encourage you to consider a tool like Cacti, which is a flexible front end for the RRDtool application. Cacti simply provides a framework and a mechanism to poll a number of sources for data regarding your systems, which can then be graphed and presented in a clear web based interface. Whereas packages like Munin provide monitoring for a specific set of metrics on systems which support the Munin plug in, Cacti provides increased freedom to monitor larger systems and more complex deployment by way of its plug in framework and web-based interface.
