lDiskSplitIOPerSec
Module: INFORMANT-STD
OID (symbolic): INFORMANT-STD::lDiskSplitIOPerSec
OID (numeric): 1.3.6.1.4.1.9600.1.1.1.1.21
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: Split IO/Sec reports the rate that I/Os to the disk were split into multiple I/Os. A split I/O may result from requesting data in a size that is too large to fit into a single I/O or that the disk is fragmented.
What is lDiskSplitIOPerSec?
This Gauge32 reports the rate at which I/O requests to the disk were split into multiple smaller I/Os, which the source notes happens when a request is too large for one I/O or the disk is fragmented -- a rising value is a hint that file fragmentation may be hurting disk performance.
