Graph Information

Field Internal name Type Warn Crit Info
Bytes wrbytes gauge      
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)
Utilization util gauge     Utilization of the device in percent. If the time spent for I/O is close to 1000msec for a given second, the device is nearly 100% saturated.
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)
sda sda_wrbytes gauge      
sda sda_avgwait gauge     Average wait time for an I/O request
sda sda_wrio gauge      
sda sda_util gauge     Utilization of the device
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.
