System monitor thresholds allow you to set up and adjust the global thresholds for when tiles on System monitor should visually indicate that your system hardware changes state, for example when the CPU usage of a server changes from a normal state (green) state to a warning state (yellow).
The system is set up with default threshold values so that you can start monitoring your system hardware from the moment your system is set up. To change threshold values, see Set system monitor thresholds.
As a default, the system is set up to show threshold values for all units of a particular hardware, for example all cameras or servers. You can also set up threshold values for individual servers or cameras or a subset of these. Setting threshold values for individual servers or cameras may be a good idea if, for example, some cameras should be allowed to use a higher Live FPS or Recording FPS that other cameras.
You can set the threshold values for servers, cameras, disks and storage. If you want to change threshold values, you can use the threshold control slider. The threshold control slider allows you to increase or decrease threshold values by dragging the handles separating states either up or down. The threshold control slider is divided into colors similar to those shown in your server or camera tiles present in System monitor.
To ensure that you do not see a Critical or Warning state in cases where the usage of or the load on your system hardware reaches a high threshold value only for a second or similar, use Calculation interval. The calculation interval feature averages out the effect of brief or frequent changes to a system hardware state. In practice, this means that the calculation interval feature evens out the effect of hardware changes over time so that you do not get alerts every time a threshold is exceeded.
For example, you can set Calculation interval to one (1) minute which ensures that you only get alerts if the average value for the whole minute exceeds the threshold. The benefit of this is that you avoid alerts about frequent and maybe possibly irrelevant changes in hardware states and only receive alerts that reflect sustained issues with, for example, CPU usage or memory consumption. To change the values of calculation intervals, see Set system monitor thresholds.
System monitor cannot calculate intervals when the recording server shuts down. This means that Live FPS and Recording FPS alerts do not average out, so they will appear instantly.
