A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Pattern Matching for Variables

You can test a string or variable against a pattern, and define an output string that is conditional on the result. You can do this by using $MATCH, which has the following syntax:

$MATCH(string, pattern, true, [false])

Specify the parameters as follows:

string: Specify a literal string (for example, TEST STRING) or a policy variable (for example <$LOGPATH>).
pattern: Specify a pattern, using HPE Operations Agent pattern matching syntax. You can create user-defined variables in the pattern to use in the parameters true and false. The pattern is case sensitive.
true: Specify a string to return if the string and pattern match. You can specify a literal string, or a user-defined variable, or a policy variable.
false: Optional. Specify a string to return if the string and pattern do not match. You can specify a literal string, or a user-defined variable, or a policy variable.

Separate each parameter with a comma (,). To specify a comma within a parameter, you must precede it with two backslashes (\\).

You can use $MATCH within your policies in all the available fields of the metric attributes.

Note In case of the Monitoring Automation deployment, $MATCH can be used with the parameters for the instruction interface. It can be also used for the automatic and user actions, which are set only with Monitoring Automation.

You can use $MATCH within your policies in the following event attributes:
