Thoughts from the abyss

Here’s an example of how to graph CPU load across SNMP using MRTG on Linux. Of course, this implies that you have MRTG running, and SNMP installed and running on Linux hosts. Install net-snmp if you don’t already have SNMP running on the host(s).

Target[host_cpu]: 1.3.6.1.4.1.2021.11.50.0&1.3.6.1.4.1.2021.11.50.0:comm@host +
1.3.6.1.4.1.2021.11.52.0&.1.3.6.1.4.1.2021.11.52.0:comm@host +
1.3.6.1.4.1.2021.11.51.0&.1.3.6.1.4.1.2021.11.51.0:comm@host
MaxBytes[host_cpu]: 100
Title[host_cpu]: CPU LOAD
PageTop[host_cpu]: <H1>Active CPU Load </H1>
Unscaled[host_cpu]: ymwd
ShortLegend[host_cpu]: %
YLegend[host_cpu]: CPU Utilization
Legend1[host_cpu]: Active CPU in % (Load)
Legend2[host_cpu]:
Legend3[host_cpu]:
Legend4[host_cpu]:
LegendI[host_cpu]:  Active
LegendO[host_cpu]:
Options[host_cpu]: growright,nopercent

This will give you the entire CPU load, User, System, and Nice in one graph. This is from the net-snmp guide: http://net-snmp.sourceforge.net/tutorial/tutorial-5/mrtg/index.html
