Creating a Threshold Alarm Profile

To create a Threshold Alarm Profile, in the Network Activate task pane, select Service Design > Manage Threshold Alarm Profile > New.

The Create Threshold Alarm Profile window appears.

  1. Enter information in the relevant fields of the Create Threshold Alarm Profile window:

    Field

    Action

    Name

    Type a name for the Threshold Alarm Profile.

    Service type

    Select the service type:

    • E-Line

    • E-LAN

    Performance Parameters

    Select the performance parameters that you want to include in the profile.

    The available parameters depend on the Service type selected.

    Valid values are:

    • Average one-way delay—Average one-way frame delay for the statistics displayed.

    • Average one-way delay variation—Average one-way “frame jitter” for the statistics displayed.

    • Best-case one-way delay—Lowest one-way frame delay for the statistics displayed.

    • Worst-case one-way delay—Highest one-way frame delay for the statistics displayed.

    • Average two-way delay—Average two-way frame delay for the statistics displayed.

    • Average two-way delay variation—Average two-way “frame jitter” for the statistics displayed.

    • Best-case two-way delay—Lowest two-way frame delay for the statistics displayed.

    • Worst-case two-way delay—Highest two-way frame delay for the statistics displayed.

    • Near-end frame loss—Count of frame loss associated with ingress data frames.

    • Far-end frame loss—Count of frame loss associated with egress data frames.

    • Near-end loss ratio—Ratio, expressed as a percentage, of the number of service frames not delivered divided by the total number of service frames during time interval T at the ingress interface.

    • Far-end loss ratio—Ratio, expressed as a percentage, of the number of service frames not delivered divided by the total number of service frames during time interval T at the egress interface.

    • Average near-end frame loss—Average frame loss measured in this session associated with ingress data frames.

    • Average near-end loss ratio—Average frame loss ratio measured in this session associated with ingress data frames.

    • Average far-end frame loss—Average frame loss measured in this session associated with egress data frames.

    • Average far-end loss ratio—Average frame loss ratio measured in this session associated with egress data frames.

    • Near-end best case loss—Lowest frame loss measured in this session associated with ingress data frames.

    • Near-end best case loss ratio—Lowest frame loss ratio measured in this session associated with ingress data frames.

    • Near-end worst case loss—Highest frame loss measured in this session associated with ingress data frames.

    • Near-end worst case loss ratio—Highest frame loss ratio measured in this session associated with ingress data frames.

    • Far-end best case frame loss—Lowest frame loss measured in this session associated with egress data frames.

    • Far-end best case loss ratio—Lowest frame loss ratio measured in this session associated with egress data frames.

    • Far-end worst case loss—Highest frame loss measured in this session associated with egress data frames.

    • Far-end worst case loss ratio—Highest frame loss ratio measured in this session associated with egress data frames.

    Click Update after you select a parameter from the drop-down list to add the parameter to the threshold alarm profile.

    Comments

    Type comments to describe the Threshold Alarm Profile.

    Perf Parameter Name

    This column displays the names of the parameters selected in the Performance Parameters field.

    Data Type

    This parameter is configured automatically, depending on the performance parameters selected. You cannot edit this field. The possible values are:

    • Absolute

    • Relative

    Observation Interval(s)

    Specify the maximum duration during which threshold crossing is allowed.

    Threshold

    Specify a threshold value. If the performance data exceeds the value specified in the Threshold field, the Junos Space application or OpenNMS software generates a threshold alarm for the selected service.

    Condition

    Specify the conditional status by which you want the performance data to be evaluated relative to the specified threshold.

    Severity

    Specify the relative severity of the performance test results, which determines when an alarm is raised:

    • Critical

    Note:

    Currently, you can specify Critical only.

    Message

    This column displays a message generated by the application according to the test being performed. This message is updated in the threshold alarm.
  2. When you complete entering information in the Threshold Alarm Profile window, click Create.
