Creating a group based on rules from the administrator console
Rule-based groups are dynamic groups created by specifying rules.
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.
This topic provides guidelines and a procedure that you can use to create dynamic groups from the administrator console.To create a dynamic group from the TrueSight console, see Setting-up-groups-to-monitor-from-the-TrueSight-console.
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.
To create a new group by specifying rules
- From the Administration Console, select the Group folder, right-click and select Add Group.
- In the Add Group dialog box in the Group Name field, specify a name (maximum length of 60 characters; no spaces) for the new group.
- In the Group Description field, specify a description for the group.
- Select Group made by specifying rules.
- Click Next. The Select Group window is displayed.
- Select the Group Name, Device Name, or Monitor Instance Name.
- Specify the Pattern Match. Instances which belong to a matching group name, device name, or monitor instance name are automatically included as the members of this group. Pattern matching supports all Java Regular Expression pattern matches.
- Select the monitor types that need to be associated to the group. Select All to include all monitor types, or select Selected to associate the selected monitor types.
- Click Add or Remove to add or remove the selected monitor types.
- Click Show Members to display the list of monitor types that match the pattern.
- Click Finish. The rule-based group is created and listed under the Group folder or click Close to return to the Administration Console without creating the group.
