Applying rules to dynamic groups

You can use a regular expression to apply a rule to a group. Infrastructure Management uses a regular expression as pattern match on groups, devices, instance names, and tags. The name pattern match can be applied to only one group, device, or monitor instance.

A tag pattern match is applied to the tag string. You also can specify a selected list of monitor types or you can choose to add all instances irrespective of the monitor type filter.

Pattern matching on an entity name

• If your entity is a group and the name regular experssion pattern matches a group name, Infrastructure Management considers all instances for that group. 
• If your entity is a device and the name regular experssion pattern matches a device name, Infrastructure Management considers all instances for that device. 
• If your entity is a monitor instance and the name regular experssion pattern matches an instance name, Infrastructure Management considers all instances with names that match that pattern.
  
  

Pattern matching on a tag

• You can tag entities with meaningful information such as location, owner, department, and so on. 
• If your entity is a group and the tag regular experssion pattern matches a group tag, Infrastructure Management considers all the instances in that group. 
• If the chosen entity is device and the tag regular experssion pattern matches a device tag, Infrastructure Management considers all instances associated to that device. 
• If your entity is a monitor instance and the tag regular experssion pattern matches an instance name, Infrastructure Management considers all instances with tags that match that pattern.
  
  

Filtering by monitor type

• All instances that result from the above pattern match are then checked for the monitor-type filter. 
• If you choose a set of monitor types, Infrastructure Management considers only those instances whose monitor type matches the selected types and discards the rest. Every instance has a monitor type.
  
  If you do not specify a monitor type, Infrastructure Management considers all of the instances.
