Get started with Operational Metrics

Complete the following setup and initial configuration steps to start using Operational Metrics.

About this task

Raw metric data, collected by data sources (such as SCOM) needs to reach the Operational Metrics MID Server, where Operational Metrics can process and analyze it. You can set up Operational Intelligence to receive raw metric data from external data sources using either pull or push mechanism.

Using either method (pulling or pushing) requires the configuration of the ITOA MetricExtension MID Server extension. The main roles of this extension are to normalize the raw data, and to detect any anomalies. The normalized data and anomalies (if above the specified threshold), are then transmitted to the instance.

Some steps for setting up Operational Metrics must be completed regardless of the method used. Other steps depend on the method used for transmitting data between the data source and the MID Server:

Pulling

This method requires using a connector that is configured to pull data from the specific data source that is collecting the raw data. Use the pre-defined SCOM connector (which was previously defined for pulling events from SCOM), or configure a new custom connector specifically for the external source that is used in your environment.

Pushing

This method uses web service APIs and is based on client-side tools that push the raw data from the external source to the MID Server. This method requires that the ITOA MetricExtension extension is configured with the Enable REST Listener option enabled.

You also need to configure the Web Server extension, which starts a Web Server on the MID Server. Request handlers are added on the Web Server that listen to any incoming metric data that was pushed from the external source.

To set up Operational Metrics following a prescribed step-by-step guidance, navigate to Guided Setup > ITOM Guided Setup, and click Continue. Then scroll to Operational Metrics, and click Continue.

Procedure

  1. Activate the ITOM Metric Management plugin.
  2. Configure a MID Server for Operational Metrics: Set up the MID Server with the required hardware, software, and configurations, and with the ITOM Metric capability from ITOM Metric Management. It is possible to use the same MID Server that is being used for Service Analytics, as a dedicated MID Server for Service Analytics and Operational Metrics. If the default SCOM connector is used, then the same MID Server that is used to collect events, should be used for Operational Metrics.
  3. Configure the Operational Metric extension.
  4. To configure for pulling:
    1. Create a connector definition (For a SCOM connector - this is already defined for pulling events from SCOM).
    2. Configure a connector instance (For a SCOM connector - see Configure the SCOM connector instance).
  5. To configure for pushing:
    1. Configure the MID Web Server extension.
    2. In the ITOA MetricExtension extension, ensure that the Enable REST Listener option is enabled, and that the MID Web Server Extension is set.
    3. Create the client scripts that push the raw data from the external source to the MID Server.
  6. Create or configure metric type registration.
  7. Choose and configure metrics to monitor.
  8. Create event rules to map raw metric data to specific CI types.
