Common web interface pages

Both Kudu masters and tablet servers expose the following information via their web interfaces:

• HTTP access to server logs.

• An /rpcz endpoint which lists currently running RPCs via JSON.

• Details about the memory usage of different components of the process.

• The current set of configuration flags.

• Currently running threads and their resource consumption.

• A JSON endpoint exposing metrics about the server.

• The version number of the daemon deployed on the cluster.

These interfaces are linked from the landing page of each daemon’s web UI.
