Traffic Health Monitoring

GigaVUE-FM monitors the traffic health of the entire Monitoring Session and each individual GigaVUE V Series Node in that session. It checks for issues like packet drops or traffic overflows.

When it detects a problem, GigaVUE-FM updates the health status of the related Monitoring Session. It monitors traffic health in near real-time.

The GigaVUE V Series Node tracks traffic levels. If traffic goes above or below the configured threshold, it alerts GigaVUE-FM. GigaVUE-FM then uses this data to calculate traffic health.

If you deploy GigaVUE-FM and GigaVUE V Series Nodes in different cloud platforms, you must add the GigaVUE-FM public IP address as the Target Address in the Data Notification Interface on the Event Notifications page.

For details, refer to the Configuration Settings section .

This feature supports GigaVUE V Series Nodes on the respective cloud platforms:

For V Series Nodes:

  • AWS
  • Azure
  • OpenStack
  • VMware
  • Third Party Orchestration

The following section provides step-by-step instructions on creating and applying threshold templates across a Monitoring Session or an application, and viewing the traffic health status. Refer to the following section for more detailed information:

 

Consideration to configure a threshold template

  • By default, Threshold Template is not configured to any Monitoring Session. If you wish to monitor the traffic health status, then create and apply threshold template to the Monitoring Session.
  • Editing or redeploying the Monitoring Session reapplies all the threshold policies associated with that Monitoring Session.
  • Deleting the Monitoring Session clears all the threshold policies associated with that Monitoring Session.
  • Threshold configuration is applied before deploying a Monitoring Session and remains even if the session is undeployed.
  • After applying threshold template to a particular application, you need not deploy the Monitoring Session again.

Create Threshold Templates

To create threshold templates:

  1. Go to Inventory > Resouces > Threshold Templates.

    The Threshold Templates page appears.

  2. Select Create to open the New Threshold Template page.

  3. Enter the appropriate information for the threshold template as described in the following table:

    Field

    Description

    Threshold Template Name

    The name of the threshold template.

    Thresholds

    Traffic Element

    Select the resource for which you wish to apply the threshold template. Ex: TEP, REP, Maps, Applications like Slicing, De-dup etc

    Time Interval

    Frequency at which the traffic flow needs to be monitored.

    Metric

    Metrics that need to be monitored. For example: Tx Packets, Rx Packets.

    Type

    Difference: The difference between the stats counter at the start and end time of an interval, for a given metric.

    Derivative: Average value of the statistics counter in a time interval, for a given metric.

    Condition

    Over: Checks if the statistics counter value is greater than the 'Set Trigger Value'.

    Under: Checks if the statistics counter value is lower than the 'Set Trigger Value'.

    Set Trigger Value

    Value at which a traffic health event is raised, if statistics counter goes below or above this value, based on the condition configured.

    Clear Trigger Value

    Value at which a traffic health event is cleared, if statistics counter goes below or above this value, based on the condition configured.

  4. Select Save.
    The newly created threshold template is saved, and it appears on the Threshold templates page.

Apply Threshold Template

You can apply your threshold template across the entire Monitoring Session and also to a particular application.

Apply Threshold Template to Monitoring Session

To apply the threshold template across a Monitoring Session, follow these steps:

  1. In GigaVUE‑FM, on the left navigation pane, select Traffic > Virtual > Orchestrated Flows and select your cloud platform. The Monitoring Session page appears.
  2. In the TRAFFIC PROCESSING tab, select Thresholds under Options menu.
  3. From the Select Template drop-down list, select the template you wish to apply across the Monitoring Session.
  4. Select Apply.

Note:  You can apply the Threshold configuration to a Monitoring Session before it is deployed. Furthermore, undeploying the Monitoring Session does not remove the applied Thresholds.

 

Apply Threshold Template to Applications

Applying threshold template across Monitoring Session does not overwrite the threshold value applied specifically for an application. When a threshold value is applied to a particular application, it over writes the existing threshold value for that particular application.

To apply the threshold template to a particular application in the Monitoring Session follow these steps:

  1. On the Monitoring Session page. select TRAFFIC PROCESSING tab. The Monitoring Session canvas page appears.
  2. Select on the application for which you wish to apply or change a threshold template and select Details. The Application quick view opens.
  3. Select the Thresholds tab.
  4. Select the template you wish to apply from the Threshold Template drop-down menu or enter the threshold values manually.
  5. Select Save.

Clear Thresholds

You can clear the thresholds across the entire Monitoring Session and also to a particular application.

Clear Thresholds for Applications

To clear the thresholds of a particular application in the Monitoring Session, follow these steps:

  1. On the Monitoring Session page, select the TRAFFIC PROCESSING tab. The Monitoring Session canvas page appears.
  2. Select the application for which you wish to clear the thresholds and click Details. The Application quick view opens.
  3. Select the Thresholds tab.
  4. Select Clear All and then select Save.

Clear Thresholds across the Monitoring Session

To clear the applied thresholds across a Monitoring Session follow these steps:

  1. In GigaVUE‑FM, on the left navigation pane, go to Traffic > Virtual > Orchestrated Flows and select your cloud platform. The Monitoring Sessions landing page appears.
  2. Select the Monitoring Session and navigate to TRAFFIC PROCESSING > Options > Thresholds,
  3. Select Clear Thresholds.
  4. On the Clear Threshold pop-up appears, select Ok.

Note:  Clearing thresholds at Monitoring Session level does not clear the thresholds that were applied specifically at the application level. To clear thresholds for a particular application refer to Clear Thresholds for Applications
