Matching String
—A Regex matching string.
NOTE:
You can configure a response to threshold crossing with an Event Processing Rule. Create your
thresholds within the monitor and then create an Event Processing Rule whose filter conditions respond
to monitorAttributeTrend and other conditions such as severity, and so on. You can even use
specific values of the event varbinds in the filter conditions too.
Threshold Graph Background
If you configure a set of thresholds, the dashboard graph displaying the data monitored displays the
threshold colors (and text label) in the background. When an upper or lower threshold has no
upper or lower bound, then those background colors may appear as white.
Inventory Mappings
The inventory mappings panel lets you associate predefined inventory metrics with a monitored
attribute to normalize the attribute if a device does not report metrics in a way that matches the
monitored attribute’s name or format. Available metrics include
CPU Utilization %, Memory
Utilization %, ICMP Round Trip Time, ICMP packet errors,
and Bandwidth utilization %.
Common attributes include those for Top N. For example, service A may call it “Disk % Utility”
and Service B may call it “% Disk Utility”. We can map them to a common name and can display
them as Top N.
