- Method Detail
  - localSpaceSize
```
long localSpaceSize()
```
    Gets local used space in bytes. This is the sum of all file chunks stored on local node.
    This is a local metric.
    
    Returns:
    Node used space in bytes.
  - maxSpaceSize
```
long maxSpaceSize()
```
    Gets maximum amount of data that can be stored on local node. This metrics is either equal to GridGgfsConfiguration.getMaxSpaceSize(), or, if it is 0, equal to 80% of maximum heap size allocated for JVM.
    
    Returns:
    Maximum GGFS local space size.
  - secondarySpaceSize
```
long secondarySpaceSize()
```
    Get used space in bytes used in the secondary file system.
    This is a global metric.
    
    Returns:
    Used space in the secondary file system or 0 in case no secondary file system is configured.
  - directoriesCount
```
int directoriesCount()
```
    Gets number of directories created in file system.
    This is a global metric.
    
    Returns:
    Number of directories.
  - filesCount
```
int filesCount()
```
    Gets number of files stored in file system.
    This is a global metric.
    
    Returns:
    Number of files.
  - filesOpenedForRead
```
int filesOpenedForRead()
```
    Gets number of files that are currently opened for reading.
    This is a local metric.
    
    Returns:
    Number of opened files.
  - filesOpenedForWrite
```
int filesOpenedForWrite()
```
    Gets number of files that are currently opened for writing.
    This is a local metric.
    
    Returns:
    Number of opened files.
  - blocksReadTotal
```
long blocksReadTotal()
```
    Gets total blocks read, local and remote.
    This is a local metric.
    
    Returns:
    Total blocks read.
  - blocksReadRemote
```
long blocksReadRemote()
```
    Gets total remote blocks read.
    This is a local metric.
    
    Returns:
    Total blocks remote read.
  - blocksWrittenTotal
```
long blocksWrittenTotal()
```
    Gets total blocks written, local and remote.
    This is a local metric.
    
    Returns:
    Total blocks written.
  - blocksWrittenRemote
```
long blocksWrittenRemote()
```
    Gets total remote blocks written.
    This is a local metric.
    
    Returns:
    Total blocks written.
  - bytesRead
```
long bytesRead()
```
    Gets total bytes read.
    This is a local metric.
    
    Returns:
    Total bytes read.
  - bytesReadTime
```
long bytesReadTime()
```
    Gets total bytes read time.
    This is a local metric.
    
    Returns:
    Total bytes read time.
  - bytesWritten
```
long bytesWritten()
```
    Gets total bytes written.
    This is a local metric.
    
    Returns:
    Total bytes written.
  - bytesWriteTime
```
long bytesWriteTime()
```
    Gets total bytes write time.
