Dear All

We have made some changes to get more performance in Netflow Analyzer Enterprise Edition for both Central server and the Collector.

Please follow the steps to tune the JAVA and MYSQL Parameters to get more performance.

Tuning Steps for the Central server :

Java Tuning Steps:

"run.bat/sh" file contains the Java parameters which is present under the <NetFlowCentral-Home>/bin directory of the Central Server installation.

For your convenience we had already configured the same in the run.bat/.sh files. You just need to comment the not required and uncomment the required parameters.

When installing as a Service in windows, follow the steps below for java tuning:

Open the file NetFlowCentral-Home/conf/wrapper.conf in a editor and set the variables "wrapper.java.initmemory" and "wrapper.java.maxmemory" to the appropriate values as in run.bat/sh

Open a command prompt and navigate to NetFlowCentral-Home/bin folder
Type "na_service -r" and press enter. (This uninstalls the service)
And then type "na_service -i" and press enter. (This reinstalls the service with the updated memory settings).

When installing as daemon in Linux:

Edit the variables in file <NetFlowCentral-Home>/conf/wrapper.conf as above.

The CentralServer can be installed as daemon by logging in as root user and executing "<NetFlowCentral-Home>/bin/startAsDaemon.sh".

After which the CentralServer can be started using the command, "/etc/init.d/netflowcentralserver start" and stopped using the command "/etc/init.d/netflowcentralserver stop".

2. Mysql Tuning Steps:

Navigate into <NetFlowCentral-Home>/conf directory and rename the file mysqlConf.txt to mysqlConf-old.txt and rename your requirement file as mysqlConf.txt

Example - If your machine is a 2 GB RAM Machine then Navigate into <NetFlowCentral>/conf directory and rename the file mysqlConf.txt to mysqlConf-old.txt and rename the mysqlConf_2GB to mysqlConf.txt and save the file

Tuning Steps for the Collector :

Java Tuning Steps:

run.bat/sh file contains the Java parameters which is present under the /bin directory of the collector installation.

You can tune them by uncommenting the required and commenting the others. run.bat tuning will not take effect while starting a service.

When installing as a Service in windows,

Open the file NetFlow-Home/conf/wrapper.conf in a editor and set the variables "wrapper.java.initmemory" and "wrapper.java.maxmemory" to the appropriate values as in run.bat/sh

Open a command prompt and navigate to NetFlow-Home/bin folder
Type "na_service -r" and press enter. (This uninstalls the service)
And then type "na_service -i" and press enter. (This reinstalls the service with the updated memory settings.).

When installing as daemon in Linux,

Edit the variables in file NetFlow-Home/conf/wrapper.conf as above.
The Collector can be installed as daemon by logging in as root user and executing "NetFlow-Home /bin/startAsDaemon.sh".

After which the Collector can be started using the command, "/etc/init.d/netflowcollector start" and stopped using the command "/etc/init.d/netflowcollector stop".

You do not have to tune the Mysql for the Collector.
