A group is a collection of monitored resources that you define. To make information easier to find and manage, you can create groups that correspond to real-world relationships (such as by city, a specific department, or the type of resource, etc.). There is no limit on the number of groups you can define. You can select individual devices, monitors, and other groups (child groups) and combine them into a single unit (group) for easier monitoring and management purposes.
Types of groups
You can monitor two types of groups in the TrueSight console. The following section briefly explains the Groups categorization and their brief description:
- Manual Groups: Groups that are created manually using the Create Group option in the TrueSight console are called Manual groups. There are two types of manual groups:
- Static groups: Static groups are groups that are created by manually adding existing devices or monitor instances. You have to manually pick and add a device or monitor instance to form a static group. For information about creating a static group, see Creating, editing, and deleting static groups.
- Rule-based groups: You can create rule-based groups that dynamically updates content based on a given rule. A rule is a combination of a pattern match on a device or monitor name, and on a condition (Equals, Contains, Starts with, Ends with).
For example, an organization has offices in three different locations—Chicago, Perth, and Copenhagen—and the devices have names based on the location of each office. If devices in Perth have names starting with "PERTH," you can create a group that consists of only those devices that belong to the Perth office. Using rule-based groups, you can create a rule with the name pattern match *PERTH** on devices. All devices that match *PERTH** are consolidated in one rule-based group. When new devices are added or existing devices are removed from the Perth office, they are automatically added or removed from the rule-based group.
For information about creating a rule-based group, see Creating, editing, and deleting rule-based groups.
- Automatically synchronized groups: Groups that are synchronized from Infrastructure Management servers are called as automatically synchronized groups. These groups can be created by configuring servers in monitoring policies from the TrueSight console or by using the Infrastructure Management administrator console.
A word about groups in automatically discovered applications
(App Visibility Manager integration) If an automatically discovered application includes a load balancing server or cluster to distribute operations among several servers with the same business need, App Visibility Manager creates a group for the application servers.The groups are dynamically created with application discovery and they are not editable, nor do they appear on the Groups page of the TrueSight console.
