The possible values are:

*SYSDFTQ

The value of this attribute is taken from the system default queue of the specified type.

*FIRST

When the number of messages on the queue goes from zero to one.

*ALL

Every time a message arrives on the queue.

*DEPTH

When the number of messages on the queue equals the value of the TRGDEPTH attribute.

*NONE

No trigger messages are written.
