Configuring the number of interfaces

IBM® Network Performance Insight® does not support automatic load-balancing.

You need to manually configure the exporter in your network to support load-balancing.

Typically, Network Performance Insight supports 1000 interfaces per collector. It is recommended that in a multiple-node environment, you configure the exporters to collect not more than 1000 interfaces per collector for processing.

To configure the number interfaces, follow these steps:
  • Configure your exporter to send not more than 1000 interfaces per collector for processing.
  • Configure the collector.flow.max-interfaces setting according to your total number of interfaces that are handled by your network exporters.
Consider the following example, which shows few exporters that are configured to collectors with the following number of interfaces:
  • Exporter 1 with 500 interfaces that is configured to Collector 1
  • Exporter 2 with 500 interfaces that is configured to Collector 2
  • Exporter 3 with 1000 interfaces that is configured to Collector 3
Set the collector.flow.max-interfaces according to your exporters configuration. For this example, set the collector.flow.max-interfaces to 2000.
Note: In this example, it does not take the traffic load into consideration.
CAUTION:

Configuring more than 1000 interfaces for a collector might cause performance issues.

If your exporter is configured to have more than 1000 interfaces in your Network Performance Insight cluster, contact IBM Professional Services for assistance.
