Enable metrics collection and evaluation
To enable a ServiceNow instance to collect and evaluate metrics, you must create a distributed MID Server cluster, associate MID Servers with the cluster, and enable Metric Intelligence for your MID Server.
Before you begin
Ensure that the following plugins are installed on your instance:
- Event Management (com.glideapp.itom.snac)
- Metric Intelligence - com.snc.sa.metric plugin
- MetricBase
To verify that the MetricBase plugin has been installed correctly:
- Enter
stats.doin the instance navigation pane. - Search for the MetricBase Statistics section and verify that the following appears:
- Status: ONLINE
- Name: clotho
Role required: agent_client_collector_admin
Procedure
-
Create a distributed MID Server cluster in your instance:
-
Navigate to MID Server > Clusters.
The MID Server Clusters page opens, displaying the list of configured MID Server clusters.

-
Click New.
The MID Server Cluster - New record page opens.
-
In the Name field, assign a descriptive name for the cluster.
-
In the Type field, select Distributed.
-
Click Submit.
The distributed MID Server appears on the MID Server Clusters page.
-
-
Assign MID Servers to the distributed MID Server cluster:
-
On the MID Server Clusters page, select the distributed MID Server cluster.
The following page appears:

-
On the Includes MID Servers tab, click Edit.
The Edit Members page appears.

-
Select the relevant MID Servers from the left cell and click the right arrow button [Omitted image "right-arrow-icon.png"] Alt text: Right arrow icon to move them to the right cell.
In a staging environment, it is acceptable to have only one MID Server in the cluster.
-
Click Save.
The Includes MID Servers tab displays the MID Servers that are part of the cluster.

-
Click New.
The Metric Intelligence Contexts - New record page appears.
[Omitted image "acc-mi-metrics-context.png"] Alt text: Metric Intelligence metrics contexts - New record form
-
In the Name field, enter a descriptive name for the Metric Intelligence metrics extension.
-
In the MID Server field, select the MID Server to which you want to associate the Metric Intelligence metrics extension.
-
Select the ACC Dedicated MID check box to assign the specified MID Server as the only MID Server in the distributed cluster.
Selecting this option helps conserve system resources and memory.
