Resource Group Manager

Your monitored environment might have multiple managed systems that can be categorized by their purpose. Such systems often have the same threshold requirements. Use the Resource Group Manager to organize managed systems into groups that you can assign thresholds to. You can also create resource groups that correlate with your role-based access control (RBAC) policies.

After you click System Configuration > Resource Group Manager, the page opens with a table of defined resource groups. Initially, one predefined system group is shown for each monitoring agent type that is installed, such as Windows OS. Each system group contains all the predefined thresholds for the agent.

Your access to the Resource Group Manager and resource groups is controlled by your user permissions. You must have View permission for a resource group to see it; you must have Modify permission to create, edit, or delete a resource group.

The table has tools for managing resource groups:

New opens the Resource Group Editor for assigning managed systems and thresholds.
Select a resource group to see the assigned resources and thresholds that are assigned to the group in the adjacent pane.
Select a resource group and click Edit to open the Resource Group Editor for changing the managed system and threshold assignments.
Select a resource group that you no longer want and click Delete. After you confirm the deletion, any thresholds that were assigned to the group must be assigned to another group if you want them to continue to run on your managed systems.
You can click inside the filter text box and type the value to filter by. As you type, the rows that do not fit the criteria are filtered out. To clear the filter, click the in the filter box or press the Backspace key.

The table displays the available resource groups:

Resource group name: Predefined groups are named for their agent type; custom groups are named by the author.
Resource group description: A predefined group is described as a system group for the monitored resource; custom groups are described by the author.; A system group, such as Linux OS, includes all the predefined thresholds for the agent and all managed systems where the agent is installed. You can edit a system group to assign or remove thresholds but you cannot assign or remove managed systems. Managed systems are automatically assigned to a system group of the same type, including any from your Tivoli® Monitoring domain if you have a Hybrid Gateway configured.; Some system resource groups relate to agents that support subnodes. Depending on the agent type, the subnodes, the agent node, or both can be added to applications. If only the subnodes can be added to defined applications, you are not able to see events for any thresholds that were defined for the agent node. However, the events can be forwarded to an event manager such as Netcool/OMNIbus.
Resource group type: Predefined groups are type System Defined. You have a predefined group for every type of agent that you have installed in your environment.; Custom groups that you or others in your environment create are type User Defined.

Resource Group Editor

After you click

New to add a group, or after you select a group and click

Edit to edit a group, the Resource Group Editor is displayed with the following fields:

Group name: The name of the group is required. You can change an existing custom group name, and all references to the group are updated automatically after you save your changes.
Group description: Optional for custom groups. Add a description of the group organization. The description is displayed in the Resource Group Manager.
Resource assignment: All the managed systems that are available for adding to the group are shown in the agent list by their managed system name, host name, agent type, and their domain. You can click a column heading to sort the list by agent name, host name, type, or domain.; To populate the group, select the check box of one or more managed systems.; You can select Show only selected resources to hide the unassigned managed systems.; If you have configured the IBM® Cloud Application Performance Management Hybrid Gateway, you can add managed systems from your IBM Tivoli Monitoring domain to user defined resource groups. You cannot add Tivoli Monitoring managed systems to system defined groups nor can you create thresholds for them.
Threshold assignment: All the thresholds that are predefined or were added through the Threshold Manager are shown in the threshold list by their name and agent type. You can click a column heading to sort the list.; To add a threshold to the group, select the check box next to the name; to remove a threshold from the group, clear the check box. You must have View permission for the Threshold Manager to add or remove thresholds. When adding thresholds to a system group, the available thresholds are limited to those whose data set is suitable for the system group.; The thresholds that you assign to the group are distributed to every managed system in the group of the same agent type. Although you can assign thresholds of any monitoring agent type to a group, the assigned thresholds are distributed only to managed systems of the same type that are members of the group. For example, if you assign the MySQL_Process_Down threshold to the group, it is included in the group, but is distributed only to the Monitoring Agent for MySQL managed systems that belong to the group.; You can select Show only selected thresholds to hide the unassigned thresholds. If you are filtering the list, click the in the filter box to clear the filter and enable the check box.; You can also assign a resource group to a threshold from the Threshold Manager.

After you click Save, the resource group is saved with the list of resource groups and displayed in the Resource Group Manager table.
