@ -11,20 +11,21 @@ If fullstat is set, it will collect a lot of per-operation statistics.
#### Measurements & Fields
- nfsstat_read
- read_bytes (integer, bytes)
- read_exe (integer, bytes)
- read_ops (integer, bytes)
- read_retrans (integer, miliseconds)
- read_rtt (integer, miliseconds)
- read_bytes (integer, bytes) - The number of bytes exchanged doing READ operations.
- read_ops (integer, count) - The number of RPC READ operations executed.
- read_retrans (integer, count) - The number of times an RPC READ operation had to be retried.
- read_exe (integer, miliseconds) - The number of miliseconds it took to process the RPC READ operations.
- read_rtt (integer, miliseconds) - The round-trip time for RPC READ operations.
- nfsstat_write
- write_bytes (integer, bytes)
- write_ops (integer, bytes)
- write_retrans (integer, bytes)
- write_exe (integer, miliseconds)
- write_rtt (integer, miliseconds)
- write_bytes (integer, bytes) - The number of bytes exchanged doing WRITE operations.
- write_ops (integer, count) - The number of RPC WRITE operations executed.
- write_retrans (integer, count) - The number of times an RPC WRITE operation had to be retried.
- write_exe (integer, miliseconds) - The number of miliseconds it took to process the RPC WRITE operations.
- write_rtt (integer, miliseconds) - The rount-trip time for RPC WRITE operations.
In addition enabling fullstat will make many more metrics available.
In addition enabling fullstat will make many more metrics available, but description of those is beyond the scope here.
