Before Configuring the Catalog search in Netvault make sure that the below 

 

Prerequisites
Before you start configuring the NetVault, verify that the following requirements are met:

•Catalog search reserved RAM size (For Windows and Linux) must not be more than 50% of the physical RAM. For low memory systems (i.e. 8 GB or less), Quest recommends to set the reserved RAM size to no more than 2 GB.

•Virtual memory (only for Linux) mmap counts on Linux is 65530, which is a default operating system limit on mmap counts. Change this value to 262144 using the following command:
sysctl -w vm.max_map_count=262144

To permanently set this value to persist after the reboot, in /etc/sysctl.conf, update the parameter vm.max_map_count.
To verify the mmap count after rebooting, run the command sysctl vm.max_map_count

•Catalog search port requirement: 9200 - 9300.
•Elasticsearch version 6.2 is compatible with many NetVault Server supported platforms. For more information, see https://www.elastic.co/support/matrix.
 
* NOTE: Catalog search installation is not supported on Debian 7 or lesser version.
•Determine NetVault catalog search Linux user account.
 
* NOTE: Sometimes, due to policy restrictions on your system, the NetVault on Linux operating system is unable to create new catalog search Linux user account automatically.
While installing NetVault catalog search, you can select any of the following options for catalog search Linux user account:

•Allow NetVault to create catalog search Linux user: The default option to allow NetVault to create Catalog search Linux user account automatically (default value: netvault-catalog on Linux).
•Linux user name: Create a new Linux user account by referring to the corresponding operating system guide. Ensure that the specified catalog search Linux user belongs to the group <user name>. Create the group with the same name as of the Linux user name and add the user into the same group.
 
* NOTE: While creating a catalog search Linux user account, do not use ‘root’ user in the field ‘Linux use name’. In NetVault, catalog search cannot run by a ‘root’ user due to restrictions from Elasticsearch component.
 
* NOTE: Catalog search sets the system level JAVA_HOME environment variable that is required for Elasticsearch. Hence, the other java applications may not work. It is assumed that the NetVault Server is a dedicated server.
