Synthetic indicators

In this lab we will learn how we can create synthetic indicators in order to combine metrics from a single object into a new KPI.

The example that we will cover in this lab shows how the Interface object type collects number of packet errors on the interface, however it does not show the percentage of packet errors compared with the total number of packets received on that interface, even though we are collecting that data. Therefore we will create a new synthetic indicator that calculates the percentage of errors received, compared with the total number of packets received.

Create Synthetic Indicator​

  1. Log into the NMS

  2. Go to Administration -> Monitoring Configuration -> Object Types

  3. Click on Interface

  1. Click on Add Synthetic Indicator Type

    a. Indicator Name: s1_InErrorsPercentage

    b. Description: In Errors Percentage

    c. Synthetic Indicator Expression: 100* ${ifInErrors}/ (${ifInErrors} + ${ifInDiscards} + useIfValid(${ifInBroadcastPkts},0) + useIfValid(${ifInMulticastPkts},0) + useIfValid(${ifInUcastPkts},0) + useIfValid(${ifHCInBroadcastPkts},0) + useIfValid(${ifHCInMulticastPkts},0) + useIfValid(${ifHCInUcastPkts},0) )

    d. Maximum Value Expression: 100

    e. Measure As: Percent

    f. Display As: Percent

    g. Click Save As New
