Configure High Performance Mode
Before You Begin
The following steps are required to operate NNM in High Performance mode. Alternatively, a user with administrative privileges can enable High Performance mode via the UI.
You must have a High Performance Activation Code in order to run NNM in High Performance mode.
NNM uses multiple cores to process packets received from monitored interfaces. These are known as worker cores. The default number of worker cores is 8. This number can be changed using the configuration parameter Number Of Worker Cores.
Note: If you set the Number Of Worker Cores parameter to 0, NNM automatically changes the value to the minimum number of worker cores needed to run NNM in High Performance mode.
For example, suppose you have 20 available logical cores. Four of those cores are used by the system for internal processing and the kernel. If you want to use the 16 available cores for NNM, then you may change the value for the parameter Number Of Worker Cores to 16.
Stop NNM with the following command:
# service nnn stop
Enable High Performance mode with the following command:
/opt/NNM/bin/nnm --config "Enable High Performance Mode" "1"
Confirm that the management network interface is different from the monitoring network interface that you configured initially.
Note: If the configured monitored interface has bound IPv4 addresses, you cannot complete the Quick Setup Wizard to configure NNM because no usable NICs appear in the Monitored Network Interfaces list.
Start NNM with the following command:
# service nnm start
