Configuring variate policies

Configure variate polices for real-time anomaly detection of various metrics that dynamically change with time.

The following video (4:30) created by BMC Customer Support describes how to create a variate policy.

To create a variate policy

On the Configuration > Multivariate Policies page, click Create, and do the following:

1. Specify a unique name and an optional description.

2. Specify the anomaly settings.

   The [expand] macro is a standalone macro and it cannot be used inline. Click on this message for details.
   This macro generates standalone content. As a consequence you need to make sure to use a syntax that separates your macro from the content before and after it so that it's on a line by itself. For example in XWiki Syntax 2.0+ this means having 2 newline characters (a.k.a line breaks) separating your macro from the content before and after it.
   

3. Save the variate policy.

   When do I start seeing the anomaly events?
   Only after the unsupervised algorithm has completed its learning phase. However, BMC Helix Operations Management is built with a robust mechanism to look for existing historical data points for the selected metrics immediately after you create a variate policy.

   - If there are enough number of data points, you can see the anomalies in a short time.

   - If there are not enough data points, the BMC Helix Operations Management needs some time to collect the minimum of 320 data points required data points for a multivariate configuration before you could see the anomalies.

Event policies do not apply to anomaly events that are generated by multivariate policies.

To view the list of variate policies

On the Configuration > Variate Policies page, view the list of variate policies.

By default, the policies are sorted by Last Updated time in a descending order. To sort on a different column, click the column heading. 

To edit a variate policy

On the Configuration > Multivariate Policies page:

1. Do one of the following:
   
   • Select the variate policy and click Edit.
   • From the Actions menu of a variate policy, select Edit.
2. Change the configuration details provided while creating the variate policy and click Save.

To delete a variate policy

On the Configuration > Multivariate Policies page:

Do one of the following:

• Select one or more variate policies and click Delete.
• From the Actions menu of a policy, select Delete, and click Yes.
