shink opened a new issue #1875:
URL: https://github.com/apache/incubator-inlong/issues/1875
### Description
We can abstract an interface so that we can use the same interface with
different monitor implementations.
For example.
```java
public abstract class AbstractSourceStatManager {
// metric
protected CounterMetric successCount;
public void incrSuccessCount() {
successCount.incr();
}
}
```
After `SourceJMXStatManager` and `SourcePrometheusStatManager` implement it,
we can use the same interface with different implementations in
`DatabaseSource`.
```java
public class DatabaseSource {
private final AbstractSourceStatManager statManager;
public MySource() {
statManager = new SourceJMXStatManager();
}
public MySource(AbstractSourceStatManager statManager) {
this.statManager = statManager;
}
public void split() {
// do something
// increment metric
statManager.incrSuccessCount();
}
}
```
```java
// prometheus.enable=false
DatabaseSource source = new DatabaseSource();
// prometheus.enable=true
DatabaseSource source = new DatabaseSource(new
SourcePrometheusStatManager(...));
source.split();
```
