• Service time (Svt_ms)
• Wait time (Wtt_ms)
• Size of the I/O requests (IOSz_KB)
• Number of rejected I/O requests (Rej)
• Averaged QoS queue length (Qlen)
• Averaged wait queue length (WQlen)
Figure 20 (page 165) shows sample output for the statqos command.
Figure 20 Run-time Statistics Shown by the statqos Command
The column headers in Figure 20 (page 165) show:
Type QoS target type (vvset or sys)
Name QoS target name; also the name of the VVset on which the rule is
defined
I/O_per_second IOPS cap, set by the userQt
Cur Current IOPS
Avg Average IOPS over all iterations of the statqos command so
far
Max Maximum IOPS over all iterations of the statqos command
so far
Kbytes_per_second IOPS cap, set by the userQt
Cur Current IOPS
Avg Average IOPS over all iterations of the statqos command so
far
Max Maximum IOPS over all iterations of the statqos command
so far
Svt_ms Total service time of I/Os processed by QoS (including wait time and
the real service time)
Wtt_ms Wait time of I/Os delayed by QoS
IOSz_KB I/O block size in KB (1 KB = 1000 bytes)
Rej Number of I/Os rejected by QoS
WQlen Number of I/Os delayed by QoS
