Default ports
Client APIs
Application clients connect to these addresses.
| API | Port | Server | Flag (default) |
|---|---|---|---|
| ysql | 5433 | yb-tserver | --pgsql_proxy_bind_address 0.0.0.0:5433 |
| ycql | 9042 | yb-tserver | --cql_proxy_bind_address 0.0.0.0:9042 |
| yedis | 6379 | yb-tserver | --redis_proxy_bind_address 0.0.0.0:6379 |
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.
Admin web server
Admin web server UI can be viewed at these addresses.
| Server | Port | Flag (default) |
|---|---|---|
| yb-master | 7000 | --webserver_interface 0.0.0.0--webserver_port 7000 |
| yb-tserver | 9000 | --webserver_interface 0.0.0.0--webserver_port 9000 |
Firewall Rules
Along with the above, include the following common ports in firewall rules.
| Service | Port |
|---|---|
| SSH | 22 |
| HTTP for Platform | 80 |

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
You can access the Prometheus server on port 9090 of the Platform node, and you can see the list of targets at the http://<yugaware-ip>:9090/targets. In particular, note port 9300 for node level metrics.
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 |
