What MIB variables and formula can be used to mimic the front panel LCD ops display?
The LCD ops display shows:
on a filer, the sum of NFS, CIFS, and HTTP ops
on a NetCache box, the total number of megabits/second (there aren't "ops" for streaming, so we fell back on Mbits/sec)
For ONTAP 6.1:
NFS ops is
tnfsCalls - "The total number of NFS calls received, since since the last boot."
That's only 32 bits, though; the full 64 bits comes from miscHighNfsOps and miscLowNfsOps, which are the upper and lower 32 bits.
CIFS ops is
cifsTotalOps - "The number of CIFS operations done by the filer, since the last time the statistics were cleared."
That's only 32 bits, though; the full 64 bits comes from miscHighCifsOps and miscLowCifsOps, which are the upper and lower 32 bits.
HTTP ops is the combination of miscHighHttpOps and miscLowHttpOps, which supply the upper and lower 32 bits of the op counts.
Summing:
tnfsCalls - "The total number of NFS calls received, since since the last boot." trpcCalls - "The total number of RPC calls received, since the last boot." cifsTotalOps - "The number of CIFS operations done by the filer, since the last time the statistics were cleared."seems to be about right. But, is there a double-count here? NFS operates over RPC.
There is, in fact, a double count there - NFS calls are, indeed, RPC calls.
