Configure the Metric Filter

You may want to add or delete metrics to or from the metric filter for the Data Center, depending on which performance metrics you want to monitor.

To configure the metric filter

1. Select the Data Center folder in the Explore pane.
2. Right-click and select Policy, Configure Collection Criteria.

   The Collection Criteria dialog appears.

3. Do one of the following:
   • Select the check box for an existing metric to modify an existing entry. The information for the selected metric populates the fields of the Details section. Make any changes and click Update.
   • Select an OS, and complete the fields in the Details section to add a new metric, then click Add.

   The metric is saved.

   The Details section contains the following fields:

   OS

   Defines the operating system for the metric being monitored.

   Type

   Defines the type of metric being monitored.

   Example:

   Type: CA Disk Group

   Sub Type: Writes per second (average)

   Sub Type

   Defines which aspect of the metric is being monitored.

   Example:

   Type: CA Disk Group

   Sub Type: Reads per second (average)

   Instance

   Defines the instance of the managed object in the MIB hierarchy.

   Example:

   Type: vmvcaim.StatClusterEffectiveCPU

   Sub Type: 1.3.6.1.4.1.546.16.52.2.7.2.1.14

   Instance: %3 [%2]

   %<n> where <n> is the numeric value listed under Instance matched to any value corresponding to the n^Th column in the respective AIM MIB table. For example, vmvcAimStatClusterTable for all row entries (instances for the same managed object). This is useful when collecting metrics for the managed object instantaneously for all instances when they are available with no user input.

   Upper Threshold (%)

   Defines the upper limit of utilization for the selected metric group.

   Default: 80%

   Lower Threshold (%)

   Defines the lower limit of utilization for the selected metric group.

   Default: 20%

   Lag

   Defines how many consecutive times the threshold breach occurs before a threshold event is generated. Configure this option to avoid flooding events for threshold evaluation. You can define an action to log threshold breach events and set up rules for threshold monitoring.

   Method

   Specifies whether the collection method is complementary, complementary delta, exact, or exact delta. The complementary method includes metrics that are not already included in a subset of that set. The exact method collects the exact metric specified.

   Category

   Specifies whether the monitored metric is a system, application, or SNMP metric.

   Default Selected Metric(s) for Collection

   Specifies whether CA Virtual Assurance collects the metrics specified by the filter by default. Unless a metrics filter is set as default, CA Virtual Assurance does not automatically collect the metrics specified.

   Include for Overall Utilization Calculation

   Specifies that you want the selected metrics to be included in the overall utilization calculation and evaluated by CA Virtual Assurance.

   Activate for Collection

   Specifies that the metric filter is effective for use when evaluating what metrics are available for collection.

4. Select the check box for any metrics that you want to delete, then click Delete.

   The selected entries are deleted.
