For the # 2 point of my update
----------------------------------
without this update,the metrics be flush into file like this(each record with
same URI mark the same "context+registry name" as begin):
{code:java}
1510631110244 s3afs.S3AFileSystem: Context=s3afs,
FileSystemId=dd721794-8269-44eb-911f-a39caa2e6b34-bdaas-demo-dfs,
fsURI=s3a://bdaas-demo-dfs/, Hostname=client01, xxx
1510631110244 s3afs.S3AFileSystem: Context=s3afs,
FileSystemId=8fe27f60-8b3d-41c1-aa84-8bb812315d55-bdaas-demo-dfs,
fsURI=s3a://bdaas-demo-dfs/, Hostname=client01, xxx
1510631110244 s3afs.S3AFileSystem: Context=s3afs,
FileSystemId=6bcf9a67-2dcd-4533-aa5b-2ded7a8ba038-bdaas-demo-dfs,
fsURI=s3a://bdaas-demo-dfs/, Hostname=client01, xxx
{code}
Note, these three records written at the same time instead of different
intervals, so they should be consider three different kinds of metrics.
(Additional, I don't know why the metrics be registered many times within a
process,like why we need to method "newMetricsSourceName")
with this update, each record will be easy to distinguish:
{code:java}
1510631110244 s3afs.S3aFileSystemMetrics: Context=s3afs,
FileSystemId=dd721794-8269-44eb-911f-a39caa2e6b34-bdaas-demo-dfs,
fsURI=s3a://bdaas-demo-dfs/, Hostname=client01, xxx
1510631110244 s3afs.S3aFileSystemMetrics2: Context=s3afs,
FileSystemId=8fe27f60-8b3d-41c1-aa84-8bb812315d55-bdaas-demo-dfs,
fsURI=s3a://bdaas-demo-dfs/, Hostname=client01, xxx
