NFS metrics

NFSIO

• nfs_read_req: Number of bytes that are requested for reading.
• nfs_write_req: Number of bytes that are requested for writing.
• nfs_read: Number of bytes that are transferred for reading.
• nfs_write: Number of bytes that are 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 that is used by read operations (in nanoseconds).
• nfs_write_lat: Time that is used by write operations (in nanoseconds).
• nfs_read_queue: Time that is spent in the RPC waiting queue.
• nfs_write_queue: Time that is spent in the RPC waiting queue.

Computed metrics

The following metrics are computed for NFS and can be used only with 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
