The Kudu master and tablet server daemons include built-in support for tracing based
on the open source Chromium Tracing framework. You can use tracing to diagnose latency issues
or other problems on Kudu servers.
Accessing the tracing web interface The tracing interface is part of the embedded web server in each of the Kudu daemons, and can be accessed using a web browser. Note that while the interface has been known to work in recent versions of Google Chrome, other browsers may not work as expected. RPC timeout traces If client applications are experiencing RPC timeouts, the Kudu tablet server
WARNING level logs should contain a log entry which includes an RPC-level trace.
Kernel stack watchdog traces Each Kudu server process has a background thread called the Stack Watchdog, which monitors other threads in the server in case they are blocked for longer-than-expected periods of time. These traces can indicate operating system issues or bottle-necked storage.
