In this document, a description about the opHA 3 features when integrating with other products will be made. 

NMIS 9

opHA will synchronise all the NMIS 9 database information. That means:

• Log files from the pollers will not be synchronise 
• RRD files will not be moved

The functional differences between a primary, poller and standalone server are as follows:

Standalone Server

• It will poll all the local nodes
• All the local nodes can be managed locally. 

Primary Server

• It can poll local nodes 
• It will have information about the remote nodes
• It will create network metrics for local and remove nodes
• Just Local nodes can be edited
• It will redirect to the poller to read information for remote nodes

Remote node is redirected from the primary.

Poller Server

• It will poll local nodes.
• Nodes must be edited from primary server.
• All the information can be read from the poller.

Node configuration view in the poller: Not possible edition.
