NMIS8 includes powerful capabilities for performance and operational thresholding. These thresholds have very granular controls which by default have been configured fairly broadly. A simple example of this is that you will likely what to be notified when the CPU is high on a Core device, vs an Access switch in Timbuktu. This is part of the NMIS idea of relevance of information in general.

Sample Controls
The crontrols are little pieces of code which will be evaluated when needed, so you might want to do the following sorts of things
| Result | Control |
|---|---|
| Apply the threshold to all devices in the group "Sales" | $group eq "Sales" |
| Apply the threshold to all devices starting with the IP address 192.168 | $host =~ /192\.168/ |
| Apply the threshold to all Cisco IOS devices | $sysDescr =~ /Cisco IOS/ |
| Use this threshold if the interface speed is between 1 and 5 megabits/second | $ifSpeed <= 5000000 and $ifSpeed >= 1000000 |
| Use this threshold if the interface speed is 10 megabits | $ifSpeed == 10000000 |
| Use this threshold if the interface speed is 100 megabits | $ifSpeed == 100000000 |
| Use this threshold if the interface speed is 1 gigabits | $ifSpeed == 1000000000 |
