You can also manually add a repeater when you expect multiple objects to be included in an alert. For example, if you have an alert set up to notify you when 5 nodes go down, you can use <<< >>> to repeat both text and variables. See the examples below.
This message with no repeater displays every node that is down in a separate sentence: ${N=SwisEntity;M=Caption} is ${N=SwisEntity;M=Status;F=Status}.
This message displays only the text included in the repeater, in this case each node that is down: <<< ${N=SwisEntity;M=Caption}>>> is ${N=SwisEntity;M=Status;F=Status}.
This message displays each node that is down and the status of each node: <<< ${N=SwisEntity;M=Caption} is ${N=SwisEntity;M=Status;F=Status}.>>>
When using a repeater, you cannot use the PREVIOUS variable.
Using macro formatters
Be aware that using macro formatters can significantly change the macro result. For example:
${N=Generic;M=Date;F=Date} - Tuesday, December 2, 2014
${N=Generic;M=Date;F=OriginalValue} - 12/2/2014
These formatters are available in the UI from the macro variable picker, and a different set of formatters is available depending on the variable value type.
