getNumberOfRegions

public int getNumberOfRegions()

Returns:

the number of regions

getInfoServerPort

public int getInfoServerPort()

getReplicationLoadSourceList

public List<ReplicationLoadSource> getReplicationLoadSourceList()

Call directly from client such as hbase shell

Returns:

the list of ReplicationLoadSource

getReplicationLoadSink

public ReplicationLoadSink getReplicationLoadSink()

Call directly from client such as hbase shell

Returns:

ReplicationLoadSink

getLoad

public int getLoad()

Originally, this method factored in the effect of requests going to the server as well. However, this does not interact very well with the current region rebalancing code, which only factors number of regions. For the interim, until we can figure out how to make rebalancing use all the info available, we're just going to make load purely the number of regions.

Returns:

load factor for this server

getRegionsLoad

public Map<byte[],RegionLoad> getRegionsLoad()

Returns:

region load metrics

getRegionServerCoprocessors

public String[] getRegionServerCoprocessors()

Return the RegionServer-level coprocessors

Returns:

string array of loaded RegionServer-level coprocessors

getRsCoprocessors

public String[] getRsCoprocessors()

Return the RegionServer-level and Region-level coprocessors

Returns:

string array of loaded RegionServer-level and Region-level coprocessors

getRequestsPerSecond

public double getRequestsPerSecond()

Returns:

number of requests per second received since the last report

toString

public String toString()

Overrides:

toString in class Object
