Internode RPC communication
Internode (server-to-server or node-to-node) communication is managed using RPC calls on these addresses.
| Server | Port | Flag (default) |
|---|---|---|
| yb-master | 7100 | --rpc_bind_addresses 0.0.0.0:7100 |
| yb-tserver | 9100 | --rpc_bind_addresses 0.0.0.0:9100--tserver_master_addrs 0.0.0.0:7100--server_broadcast_addresses 0.0.0.0:9100 |
If you want to log into the machines running these servers, then the ssh port 22 should be opened as well.

Prometheus monitoring
YugabyteDB servers expose time-series performance metrics in the Prometheus exposition format on multiple HTTP endpoints. These endpoints have the following structure.
<target>/prometheus-metrics
Following is the list of targets available.
Servers
Use the following targets to monitor yb-tserver and yb-master server metrics.
| Server | Target |
|---|---|
| yb-master | <yb-master-address>:7000 |
| yb-tserver | <yb-tserver-address>:9000 |
APIs
Use the following yb-tserver targets for the various API metrics.
| API | Target |
|---|---|
| ysql | <yb-tserver-address>:13000 |
| ycql | <yb-tserver-address>:12000 |
| yedis | <yb-tserver-address>:11000 |
