RRD by Example

Outlined Area Graph

I frequently get asked about how I created the Interconnect Utilisation graph that is shown as an example in the  RRDTool gallery. Here is a quick description of how it's done. B.Golden

Use RRD as system health and usage monitor

As it is well known, RRD is very useful to create graphs of system usage (CPU usage, load, HDD read/write activity and network load) or system health (esp. temperatures) over time. However, many people will find it hard to actually do this, because there is a lot to be learned beforehand. Now, here's an example set of scripts that will greatly simplify this task.

Use RRD with lm-sensors and these 2 scripts to monitor sensor output

I needed a simple to use program to monitor the output of hddtemp and the sensor command. I came across the website of Martin Pot  http://martybugs.net/linux/hddtemp.cgi where he posted 2 scripts to monitor harddisk temperatures and an excellent tutorial to get it all working with RRD. I modified these scripts to use the output from the sensor command so I can log and graph this as well.
