  • [New] obdiag V3.2.0 is adapted to ob-operator.

  • [Optimized] obdiag V3.2.0 fixes the issue of compatibility in deployment on Debian 11 or later.

  • [New] The obdiag gather stack command can be used to collect stack information of OceanBase clusters running on servers with Arm architecture.

  • [New] The obdiag check command supports five new inspection scenarios. Specifically, it can be used to check the number of log stream replicas, status of zones, clock of the host, number of log files retained for an OceanBase cluster, and network packet loss.

  • [New] The obdiag check command can be used to check parameters of OceanBase Database Proxy (ODP).

  • [Optimized] obdiag V3.2.0 fixes the issue where the obdiag gather plan_monitor command cannot obtain the table schema when an SQL statement involves multiple databases.

Notice

To use obdiag V3.2.0 on an OceanBase cluster deployed by using OceanBase Deployer (obd), the version of obd must be V3.2.0 or later.
