"1" are the underlying filesystem operations, "ifs" as in /ifs is the actual filesystem of OneFS.  "2" are the protocol operations of the network "filesystems" like NFS and SMB  (both not to confuse with raw disk I/O operations)  There are usually internal "ifs" operations going on for the OneFS job engine and other activities like syncing configs and so on, even when no NFS or SMB requests are being served.  makes sense?  -- Peter
Does anybody know why "# isi statistics query --stats node.ifs.ops.in.rate" output is very different from that of "# isi statistics system --oprates --nodes"? Both commands check imput "ops/s" of Isilon but it seems to me the two commands provide different information from the same Isilon.   # isi version Isilon OneFS v7.2.1.4 B_MR_7_2_1_4_078(RELEASE): 0x70201500040004E:Sat Sep  3 10:29:28 GMT 2016    root[NAME]-build7-101:/b/mnt/obj/b/mnt/src/sys/IQ.amd64.release   clang version 3.3 (tags/RELEASE_33/final) # isi statistics describe --stats node.ifs.ops.in.rate Stat key             => Description node.ifs.ops.in.rate => Operation input rate to /ifs on the node (ops/sec) # isi statistics describe --stats node.ifs.ops.out.rate Stat key              => Description node.ifs.ops.out.rate => Operation output rate to /ifs on the node (ops/sec) # isi statistics query --stats node.ifs.ops.in.rate  <= 1.

"# isi statistics query --stats node.ifs.ops.in.rate" shows several ops/sec counts but 2. "# isi statistics system --oprates --nodes" indicates there was no Ops/s in any protocol (SMB, FTP, HTTP, ISCSI, NFS, and HDFS). How can we understand the different outputs?  Thank you,
How to read "isi statistics" outputs?
