Scenarios
Examples

Scenarios

You can use the obdiag rca run command to analyze the log_error scenario based on internal table data and logs of OceanBase Database.

OceanBase Database V4.0.0.0 and later are supported for this feature. When you use obdiag commands, you must configure cluster information in the config.yml file stored in the ~/.obdiag directory or by specifying --config options in the commands.

Notice

  • Internal data is updated in real time. Therefore, obdiag only supports the analysis of current data.

  • At present, obdiag can analyze only the absence of a leader in a log stream.

Examples

Specify the scenario in the command.

obdiag rca run --scene=log_error
