Available performance graphs

You can display graphs of NAS Server data for review. For NAS modules, an external NAS Manager can display the data. The following graphs are available:
  • File system performance (operations per second)
  • File system capacity
  • Storage pool capacity
  • Node operations (a stand-alone server is displayed as a single node).
Graph Describes Units of measurement
File System Ops/Sec For each of the selected file systems (up to five), the number of operations the selected file systems is processing, either for read or write. Operations/second
File System Capacity The total capacity of a single file system, including live data and snapshot usage. MB (megabytes), GB (gigabytes), TB (terabytes), or PB (petabytes)

NoteThe maximum size of a file system is 1 PB, but a 1 PB file system is only supported on an HDP storage pool.
Storage Pool Capacity The total capacity of a single storage pool. MB (megabytes), GB (gigabytes), or TB (terabytes)
Node ops Operations per second on the node. Operations/second
Ethernet Throughput Ethernet throughput; both RX (received) and TX (transmitted). Mb/sec (megabits per second)
System load File system load on the hardware of the server/node.

Refer to the hardware references for information about the hardware in your server/node.
