> Collect and monitor the general performance Metrics of OceanBase database. Support OceanBase 4.0+.
|
||
|
||
## Driver selection
|
||
|
||
OceanBase now follows the same automatic routing as the MySQL-compatible query path:
|
||
|
||
- If `mysql-connector-j` is present in `ext-lib`, the JVM collector or built-in server collector automatically prefers JDBC.
|
||
- If `mysql-connector-j` is absent, HertzBeat automatically uses the built-in MySQL-compatible query engine. No extra JAR is required.
|
||
- Restart HertzBeat or the standalone JVM collector after adding or removing a JAR in `ext-lib`.
|
||
|
||
:::important Collector package selection
|
||
OceanBase monitoring now supports both JVM and native deployment.
|
||
|
||
- Built-in server collector or JVM collector package: automatically prefers JDBC when `mysql-connector-j` exists in `ext-lib`
|
||
- Native collector package: supported when you do not rely on `ext-lib` and want the built-in MySQL-compatible query engine
|
||
- If you explicitly need runtime `ext-lib` JDBC loading, choose the JVM collector package
