Specifying the Alert Message

An alert message can be a simple text string, or it can use parameters.

Below are two examples showing parameter-based messages:

"{0}''s garbage collection time {2} for {1} has crossed 10% of {3} uptime"
"{0}''s used memory {2} has crossed 95% of {3} max memory at {1,date,short} {1,time,short}"

The message supports the following substitutions (using Java Message Format syntax).

Alert Message Parameters
Parameter Value
{0} The name of the cluster member that the alert is about.

Specified by the condition/getproperty@path attribute.

{1} The category that the alert is about.

Specified by the PaneType/SeriesName/CategoryValue/... part of the condition/getproperty@name path.

{2} The actual value that is causing the alert to be triggered, as specified in the condition/getproperty@name.
{3} The reference value, used to calculate whether a metric value is of concern (and the alert is therefore triggered).

Specified by the condition/getproperty@reference attribute.
