Viewing operating statistics for file serving nodes
Periodically, the file serving nodes report the following statistics to the Fusion Manager:
• Summary. General operational statistics including CPU usage, disk throughput, network
throughput, and operational state. For information about the operational states, see “Monitoring
the status of file serving nodes” (page 75).
• IO. Aggregate statistics about reads and writes.
• Network. Aggregate statistics about network inputs and outputs.
• Memory. Statistics about available total, free, and swap memory.
• CPU. Statistics about processor and CPU activity.
• NFS. Statistics about NFS client and server activity.
The GUI displays most of these statistics on the dashboard. See “Using the GUI” (page 14) for
more information.
To view the statistics from the CLI, use the following command:
ibrix_stats -l [-s] [-c] [-m] [-i] [-n] [-f] [-h HOSTLIST]
Use the options to view only certain statistics or to view statistics for specific file serving nodes:
-s Summary statistics
-c CPU statistics
-m Memory statistics
-i I/O statistics
-n Network statistics
-f NFS statistics
-h The file serving nodes to be included in the report
