System Monitor Thresholds (System Dashboard node)

System monitor thresholds allow you to define and adjust the thresholds when tiles on the System monitor dashboard 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) or from a warning state (yellow) to a critical state (red).

Thresholds between the three hardware states in System Monitor.

Example of thresholds between the three states

You can change thresholds for servers, cameras, disks, and storage, and all thresholds have some common buttons and settings.

Common user interface elements

Buttons & settings	Description	Unit
Calculation interval	Often there are short outages in the connection to your different hardware. If you specify a calculation interval of 0 seconds, all these short outages will trigger alerts about changes in hardware state. Therefore, define a calculation interval of some length. If you define a one (1) minute calculation internal, it means that you only get alerts if the average value for the whole minute exceeds the threshold. With the correct calculation interval setting, you will not receive false-positive alerts but only alerts about sustained issues with, for example, CPU usage or memory consumption. To change the values of calculation intervals, see Edit thresholds for when hardware states should change.	sec
Advanced	If you select the Advanced button, you can define thresholds and calculation intervals for individual servers, cameras, disks, and storage. For more information, see below.	-
Create rule	You can combine events from System Monitor and rules to trigger actions, for example, when a server's CPU usage is critical, or a disk is running out of free space. For more information, see Rules and events (explained) and Add rules.	-

Calculation interval

Often there are short outages in the connection to your different hardware. If you specify a calculation interval of 0 seconds, all these short outages will trigger alerts about changes in hardware state. Therefore, define a calculation interval of some length.

If you define a one (1) minute calculation internal, it means that you only get alerts if the average value for the whole minute exceeds the threshold. With the correct calculation interval setting, you will not receive false-positive alerts but only alerts about sustained issues with, for example, CPU usage or memory consumption.

To change the values of calculation intervals, see Edit thresholds for when hardware states should change.

Advanced

If you select the Advanced button, you can define thresholds and calculation intervals for individual servers, cameras, disks, and storage. For more information, see below.

Create rule

You can combine events from System Monitor and rules to trigger actions, for example, when a server's CPU usage is critical, or a disk is running out of free space.

For more information, see Rules and events (explained) and Add rules.
