Configuring LogLogic EVA for a Large Number of Devices

For LogLogic EVA to connect to a large number of devices, you must change the value of JAVA_OPTS and max_devices parameters for the LXVirtual, STVirtual, or MXVirtual appliance.

By default, the value of the max_devices parameter is set to 16,000. If you want your LogLogic EVA instance to connect to more devices or log sources, then you can change the value up to the maximum value allowed for that platform.

Procedure

Navigate to /loglogic/conf/capability.xml.
In the file, locate the appropriate sections for the LXVirtual, STVirtual, or MXVirtual appliance.

Change the max_devices parameter to the required value.

For example, 100000:

<applianceProperty>
                <propertyName>max_devices</propertyName>
                <propertyvalue>100000</propertyValue>
</applianceProperty>

Adjust the -Xms and Xmx parameters so that the memory allocated is 1 GB.

For example:

<applianceProperty>
                <propertyName>JAVA_OPTS</propertyName>
                <propertyValue>"Xms1024M -Xmx1024M"</propertyValue>
</applianceProperty>

For the changes to take effect, restart all engines by running the following commands:
1. $ mtask stop
2. $ mtask start
