Collectd Pandora FMS: Maximizing Monitoring Efficiency
Collectd is a daemon (i.e. running in the background on computers and devices) that periodically collects metrics from different sources such as operating systems, applications, log files, and external devices, providing mechanisms to store values in different ways (e.g. RRD files) or makes it available over the network. With this data and its statistics you may monitor systems, find performance bottlenecks (by performance analysis) and predict system load (capacity planning).
