Using Wildcards to Represent PATROL Instance Names

When you set up parameter threshold or poll time rules, you may want to create one rule that matches several PATROL instances. For example, you may want to create a parameter threshold rule for any process that contains the letters WIN. You can do this using wildcards. 

PATROL KM for Event Management uses the following set of characters to identify a wildcard: {re:*}. 

For more information, see the following example.

Requirements for Using Wildcards

The following usage rules apply to wildcards:

• You can use wildcard only when the processWildcards configuration variable is enabled.
• You can use a wilcard only to represent PATROL instance names. You cannot use wildcards to represent host names, parameter names, or any other PATROL object.
• You can use wildcards only in threshold and poll time rules. You cannot use wildcards in notification rules.
• You can use only one wildcard in an expression.
• You cannot use wildcards to specify the beginning or ending of an instance name. For example, CPU_{re:*} matches both HoustonCPU_03 and CPU_03.
• Rules that use explicit instance names take precedence over rules that contain wildcard matches.
• Rules that contain wildcard matches take precedence over rules that use the __ANYINST__ variable to represent any instance name.
