You set up and maintain the physical or virtual machine on which NetWitness Platform services run in the Hosts view.
IMPORTANT: For help on resolving errors you receive during version installation and update, see Troubleshooting Version Installations and Updates .
A service performs a unique function, such as collecting logs or archiving data. Each service runs on a dedicated port and is modeled as a plug-in to enable or disable, according to the function of the host. You must configure the Core services first.
You must configure hosts and services to communicate with the network and each other so they can perform their functions such as storing or capturing data.
Workflow
This workflow shows the procedures you complete to set up a host, maintain a host, and update the host with new NetWitness Platform versions. Setting up a host is the first task in this workflow. The hosts with core services are set up out-of-the-box. After that, you can set up additional hosts to enhance your NetWitness Platform deployment. The other two tasks, maintaining a host and updating versions for a host, are performed when required and do not have a specific order of completion.
