Configuring Metric Data Forwarding

To forward metric data after policy rules are applied, configure the metric forwarding rules.

Metric forwarding rules define what a Data Forwarding policy should do in response to specific metric data. Each rule consists of a condition and of settings for the data generated by the policy. The settings enable you to configure what data Operations Connector forwards to which target.

To access

In the Operations Connector user interface, click in the toolbar. Then click Forwarding > Data Forwarding.

Alternatively, double-click an existing policy to edit it.

Click Metric to open the policy Metric page.

Rule types

The rule types are:

• Forward on matched

  If matched, Operations Connector forwards the metric data to the specified targets.

• Discard on matched

  If matched, Operations Connector discards the metric data.

• Discard on unmatched

  If not matched, Operations Connector discards the metric data.

Contrary to rules for other policies where processing stops when a rule is matched, all rules are processed for every data type. Operations Connector then compares the lists of targets to which the data should be sent to with the list of targets where data should be discarded. The final result is a list of targets where the data record should be sent to. This means that discard rules have a higher precedence.

Conditions

For each rule, a list of conditions can be evaluated input data is processed. The list of conditions is evaluated using the logical and operator.

Each condition consists of a left and right hand operand which are compared using an operator. The left hand operand is a reference to the data evaluated. A data reference is addressed using its key. The available keys - the Operations Connector Metric Meta Model - are shown by Operations Connector in the Meta Data tab.

Tasks

How to configure data forwarding:

1. In the Data Forwarding Rules list, click above the Description column to add a new rule. Select the rule type.

2. In the Properties tab, enter a description for the rule.

3. In the Condition tab, click to add new conditions.

   1. In the Property field, enter the name of the property or drag it from the Meta Data tab.

   2. Select the pattern operator.

      For a list of available operators, see Condition Tab.

   3. In the Operand field, type the value or pattern that you want the policy to compare with the property.

4. In the Targets tab, select one or more targets from the list of available targets. For the rule to affect all targets, you select the option Affect all targets.

   Optionally, you can override the target configuration for individual or all targets by selecting the option Override Target Configuration. If you select this option, you can change the Wire Format and change the setting of the Use Guaranteed Delivery option.
