OpsCenter and DataStax agent ports
Default port numbers used by OpsCenter and the DataStax Agents.
Port | Description |
---|---|
OpsCenter ports | |
8888 | OpsCenter website. The opscenterd daemon listens on this port for HTTP requests coming directly from the browser. Configurable in opscenterd.conf. |
50031 | OpsCenter HTTP proxy for Job Tracker. The opscenterd daemon listens on this port for incoming HTTP requests from the browser when viewing the Hadoop Job Tracker page directly. Configured in opscenterd.conf. (DataStax Enterprise only) |
61620 | OpsCenter monitoring port. The opscenterd daemon listens on this port for TCP traffic coming from the agent. Configured in opscenterd.conf. |
DataStax agents ports (on the monitored nodes) | |
7199 | JMX monitoring port. Each agent opens a JMX connection to its local node (the Cassandra or DataStax Enterprise process listening on this port). The JMX protocol requires that the client then reconnect on a randomly chosen port (1024+) after the initial handshake. This port is set in the cluster-specific configuration file. |
8012 | Hadoop Job Tracker client port. The Job Tracker listens on this port for job submissions and communications from task trackers; allows traffic from each Analytics node in a DataStax Enterprise cluster. |
8012 | Hadoop Job Tracker website port. The Job Tracker listens on this port for HTTP requests. If initiated from the OpsCenter UI, these requests are proxied through the opscenterd daemon; otherwise, they come directly from the browser. (DataStax Enterprise only) |
8012 | Hadoop Task Tracker website port. Each Task Tracker listens on this port for HTTP requests coming directly from the browser and not proxied by the opscenterd daemon. (DataStax Enterprise only) |
9042 | The native transport port for the cluster configured in
native_transport_port in
cassandra.yaml. Set in cql_port . |
61621 | DataStax agent port. The agents listen on this port for TCP traffic initiated by OpsCenter. cluster-specific configuration file. |
22 | SSH port. Configurable in opscenterd.conf. |
Solr Port and Demo applications port | |
8983 | Solr Port and Demo applications port. |
