2.2. Default Server, Agent, and Storage Node Ports
- Server to database communication
- The server has to be able to connect to its database. The database port number depends on both the type of database and the specific configuration for the database.
- Server to agent communication
- The server connects to an agent over a single port configured for the agent. This port is used for both standard and SSL communications between the server and agent.
- Agent to server communication
- An agent can talk to multiple JBoss ON servers, even if they use the same port (since each server is on a different host.) The agent will use either a standard port or an SSL port to connect to the JBoss ON server, depending on the connection (transport) method that is configured. The agent will only attempt to use a single port.
- Server to storage node communication
- The JBoss ON server receives the monitoring data from an agent, and it then forwards that information to an available storage node. THe server connects to the storage node over its client (CQL) port.
- Storage node to storage node communication
- For data integrity and availability, the monitoring data are regularly synchronized between the storage nodes. The nodes send data to one another over a communal cluster port, called a gossip port.
