By default, the YB-Master and YB-TServer nodes report cluster diagnostics to the Yugabyte diagnostics service every time a new cluster gets created and every hour thereafter.

No data stored in YugabyteDB or personally identifiable information is collected or reported.

Data collected

The data collected depends on the collection level. To change the collection level, see Configure diagnostics collection.

Collection level: low

The following data is collected:

• Collection time
• Cluster uuid
• Node uuid
• Node type (tserver or master)
• Number of masters (yb-master processes)
• Number of tablet servers (yb-tserver processes)
• Number of tables
• Number of tablets
• Cluster configuration (gflags)
• Host name (for each node where yb-master and yb-tserver processes are running)
• Username (for each node where yb-master and yb-tserver processes are running)

Collection level: medium [Default]

In addition to the low-level data, the following data is collected:

• Performance metrics
• RPC metrics

Collection level: high

Same as medium level. No extra information is collected for this level. This level may be used in the future to collect additional diagnostics information such as error logs.

Example of metrics collected

The following is an example of a payload that is collected:

Configure diagnostics collection

You can add the following configuration flags while starting the YB-Master and YB-TServer nodes to configure the diagnostics reporting behavior of YugabyteDB.
