Graph Information

This graph shows average waiting time/latency for different categories of disk operations. The times that include the queue times indicate how busy your system is. If the waiting time hits 1 second then your I/O system is 100% busy.

Field Internal name Type Warn Crit Info
Write IO Wait time avgwrwait gauge 0:3    Average wait time for a write I/O from request start to finish (includes queue times et al)
IO Wait time avgwait gauge     Average wait time for an I/O from request start to finish (includes queue times et al)
Device IO time svctm gauge     Average time an I/O takes on the block device not including any queue times, just the round trip time for the disk request.
Read IO Wait time avgrdwait gauge 0:3    Average wait time for a read I/O from request start to finish (includes queue times et al)
