rich7420 opened a new pull request, #10846:
URL: https://github.com/apache/ozone/pull/10846
## What changes were proposed in this pull request?
It would be better to not use netty internal `maxDirectMemory` and
`usedDirectMemory` in NettyMetrics#getMetrics.
`usedDirectMemory` can be replaced by netty public api. For example:
```
public long getUsedDirectMemory() {
ByteBufAllocator allocator = ByteBufAllocator.DEFAULT;
if (allocator instanceof ByteBufAllocatorMetricProvider)
{ ByteBufAllocatorMetric metric = ((ByteBufAllocatorMetricProvider)
allocator).metric(); return metric.usedDirectMemory(); }
return -1L;
}
```
`maxDirectMemory` depends on system property and jvm setting.
