How thresholds work in SRM

Thresholds are the values assigned to metrics of a monitored device or device type to indicate the levels at which the device require attention. You can set Critical and Warning status thresholds for each metric for each object type (or individual objects).

In the following example, the Latency (Total) threshold for LUNs is set to 20 milliseconds or higher for Critical, and 10 to 19 milliseconds for Warning.

The widget on the right shows three LUNs and their current latency:

• The first LUN exceeds the Critical level threshold, so Latency is shown against a red background, and the resource name is preceded by the Critical icon.
• The second LUN exceeds the Warning level but not the critical level so is shown against a yellow background, and the resource name is preceded by the Warning icon.
• The third LUN is below the Warning level so it is not highlighted, and the resource name is preceded by the Up icon.
