Configuring Entity thresholds

A threshold is a value that is compared against a metric to determine whether the metric violates a specific constraint. Entity thresholds provide a mechanism for identifying anomalies in performance metrics that is polled from Network Performance Insight® and Cacti.

About this task

Events can be created when a performance metric exceeds a certain user-defined value. For example, when the response time for a monitored service is too high, or when bandwidth utilization exceeds a certain amount.

The threshold violations and their values are user-defined and not dynamically generated. You can configure entity thresholds for each of the performance metrics that are collected and stored in Network Performance Insight database.

Important: Entity Threshold configuration is required in the following installation scenarios:

Procedure

  1. Click Console Integrations (Console integrations icon) in the navigation bar and select Entity Thresholds under System Configuration.

    You can see the Entity Thresholds table.

  2. Select the threshold that you want to edit.
  3. Click the Edit (Edit button) icon.

    The Edit Entity Threshold window displays the configuration details.

  4. Modify the settings for the threshold as needed.
    1. Select the limit type from the Limit Type list to Over, Under, or Band.
      Over
      Detect violations when the metric value exceeds the set threshold value.
      Under
      Detect violations when the metric value falls short of the set threshold value.
      Band
      Detect violations the metric value goes outside a range (or band) between two set threshold values.
    2. Enter a value in the Upper Limit field for the metric to trigger a threshold violation.
    3. Enter a value in the Lower Limit field for the metric to trigger a threshold violation.
    4. Enter the number of events for triggering the threshold in the Consecutive Occurrences field.
    5. Select the Enabled check box to enable a threshold on the interface.
    6. Click Ok to save the modification.
    Note: When the threshold limit is violated, it displays the severity as Critical.

    For more information, see Threshold levels in Threshold violation.

  5. You can perform the following tasks in the Actions column:
    1. Click Edit to edit or configure the selected threshold.
    2. Click Enable or Disable to enable or disable a metric to detect its threshold violation states.

Results

Any metric that is violating the configured threshold value is reported in the Event Viewer.

What to do next

You must repeat the same process to enable and configure thresholds for every metric as needed.
