CockroachDB's Admin UI provides detail about your cluster's performance and health.
Access the Admin UI
You can access the UI from any node in the cluster, each of which will show nearly identical data.
By default, you can access it via HTTP on port 8080 of whatever value you used for the node's --host value. For example, http://<any node host>:8080.
However, you can also set the CockroachDB Admin UI to a custom port using --http-port or a custom hostname using --http-host when starting each node (i.e., each node's values are dependent on how it's started; there is no cluster-level configuration for non-default values). For example, if you set both a custom port and hostname, http://<http-host value>:<http-port value>.
For additional guidance on accessing the Admin UI, see Start a Local Cluster and Manual Deployment.
