Track connections to/from a particular source/destination. Detect excessive or unexpected connection totals for a particular device or network available service.

Configure a Network Traffic Analysis conversation partners threshold:

• Name. Used in the Threshold library and the quick select title on the Alert Center Dashboard.
• Notification Policy. (Optional) Select the notification policy to apply to this threshold. The policy initiates notifications when an item is outside the configured threshold limits.
• Threshold Check Interval. Enter a time interval for Alert Center to check the Network Performance Monitor database for items that are out of the threshold limits.

  Automatically resolve items no longer out of threshold. Select to have Alert Center automatically resolve items when they return to the parameters inside the threshold.

Note: Notification policies are optional for most thresholds. If you do not select a notification policy, no notifications are generated for the threshold, but a dashboard report listing the out of threshold items still appears on the Alert Center Home page.

Add Condition Rules

• a host has... Select the direction(s) of traffic to consider.
• more than... Select a magnitude (limit) for conversation partners.
• in the past... Select a period for the measurement.

Select Applied Hosts

Note: Sources sending sampled data are not displayed as a selection option in the Traffic to monitor list because Network Traffic Analysis cannot determine that traffic has failed on sampled data.

• Traffic to monitor. By default, the threshold is set to monitor traffic from all Network Traffic Analysis Sources. Select the Network Traffic Analysis source or interface from which to monitor traffic. When you select a source, traffic for all interfaces on the source is monitored. When you select an interface, only traffic for the selected interface is monitored.

  Tip: When you select a source, traffic for all interfaces on the source is monitored. When you select an interface, only traffic for the selected interface is monitored.

• Hosts to monitor. By default, the threshold monitors all applicable hosts. You can also select IP ranges and IP Groups.
  • All Hosts. By default, the threshold monitors all applicable hosts

    Exclude Hosts. Select to ignore the traffic for a list of hosts you assemble here.

  • Specific Hosts. Click Apply this Threshold to Specific Hosts to choose the hosts to which the threshold applies.

    

Note: Configure the threshold check interval for a longer time than the sampling interval for thresholds relating to trends, such as percent utilization. Configure it for a time the same as (or similar to) the sampling interval when configuring a threshold for a health check.

Tip: Avoid setting the threshold check interval to a very short time. Aggressive intervals can degrade system performance. In general, setting the threshold check interval to less than five minutes is not advised.

Clone a threshold based on a custom or built-in configuration:

1. Click on a threshold on the Thresholds Library panel you want to copy.
2. Click the Copy button, and click OK to create a new Conversation Partners Threshold.

   The Edit Conversation Partners Threshold dialog displays.

3. Save or customize your new threshold, either:
   • Type in a new value for Name field (or keep the default) and click OK to save to the Thresholds Library.
   • Follow the Edit Conversation Partners Threshold instructions.

Delete an existing Conversation Partners Threshold:

1. Select Conversation Partners Threshold you want to delete from the Conversation Partners Threshold panel.
2. Click the Delete button, and then click Yes to confirm the deletion.

   The Conversation Partners Threshold configuration is deleted.
