Has anyone else noticed that ziostat does not seem to be providing correct
rolling updates in current-ish SmartOS?
Behavior observed when running "ziostat -Z 5" on 20160804T173241Z was plausible
rollup stats on first output, and then zeroes for all metrics, even when
deliberately flogging the disk subsystem:
[root@80-c1-6e-64-9b-24 ~]# ziostat -Z 5
r/s kr/s actv wsvc_t asvc_t %b zone
0.0 0.1 0.0 28.1 5.7 0 global (0)
0.0 0.2 0.0 0.3 1.6 0 8d31ffe3 (1)
0.2 0.4 0.0 2.6 2.4 0 a450a6d4 (2)
r/s kr/s actv wsvc_t asvc_t %b zone
0.0 0.0 0.0 0.0 0.0 0 global (0)
0.0 0.0 0.0 0.0 0.0 0 8d31ffe3 (1)
0.0 0.0 0.0 0.0 0.0 0 a450a6d4 (2)
r/s kr/s actv wsvc_t asvc_t %b zone
0.0 0.0 0.0 0.0 0.0 0 global (0)
0.0 0.0 0.0 0.0 0.0 0 8d31ffe3 (1)
0.0 0.0 0.0 0.0 0.0 0 a450a6d4 (2)
We're getting plausible numbers when doing the same thing on a (different
machine, same hardware) 20160218T022556Z global zone.
No, I haven't resorted to a binary search to figure out when the regression
went in.
Thanks,
