Agents deployed to network devices for the purposes of collecting log data must be able to connect to the dedicated database instance used by Log Management as well as the WhatsUp Gold server itself. It is highly recommended you deploy the standard version of Elasticsearch which supports encryption and authentication. You also need to ensure the Elasticsearch database is reachable by all devices where an Agent is going to be deployed. This means the host name specified in the Log Management General Settings for the Elasticsearch database is resolvable by all devices where an Agent is deployed just like the Certificate Common Name. For additional information about the Certificate Common Name setting, see About the Certificate Common Name. Additionally, please ensure any firewalls that may exist between Agent devices and the server hosting the Elasticsearch instance permit connections to the Elasticsearch database.
