NFS metrics
The following section lists all the NFS metrics::
NFS
NFSIO
- nfs_read_req: Number of bytes requested for reading.
- nfs_write_req: Number of bytes requested for writing.
- nfs_read: Number of bytes transferred for reading.
- nfs_write: Number of bytes transferred for writing.
- nfs_read_ops: Number of total read operations.
- nfs_write_ops: Number of total write operations.
- nfs_read_err: Number of erroneous read operations.
- nfs_write_err: Number of erroneous write operations.
- nfs_read_lat: Time consumed by read operations (in ns).
- nfs_write_lat: Time consumed by write operations (in ns).
- nfs_read_queue: Time spent in the rpc wait queue.
- nfs_write_queue: Time spent in the rpc wait queue.
Computed Metrics
The following metrics are computed for NFS. These metrics can only be used only through the
mmperfmon query command.
- nfs_total_ops: nfs_read_ops + nfs_write_ops
- nfsIOlatencyRead: (nfs_read_lat + nfs_read_queue) / nfs_read_ops
- nfsIOlatencyWrite: (nfs_write_lat + nfs_write_queue) / nfs_write_ops
- nfsReadOpThroughput: nfs_read/nfs_read_ops
- nfsWriteOpThroughput: nfs_write/nfs_write_ops
