CASE WHEN qlen > 0 THEN qlen ELSE 0 ENDQueue length
The check for qlen > 0 is because qlen < 0 indicates that qlen is invalid for that sample.

Service Time Histogram Buckets
The service time range corresponding to each of the rhist and whist buckets depends on the version
of the HP 3PAR OS (os_rev column in the system table, see “The system Table” (page 196)). For
os_rev prior to 2.2.2, the nth bucket (rhistn and whistn) correspond to service times from the
previous bucket to (2n*4.096/mhz) millisec where mhz is the mhz column in the system_3 table
(see “The system Table” (page 196)). This means that service time histograms from systems with
different CPU frequencies could not be correctly aggregated. Beginning with the 2.2.2 release,
the buckets were made independent of the CPU frequency, and the nth bucket (rhistn and whistn)
corresponds to service times from the previous bucket to (2n-7) millisec.
IO Size Histogram Buckets
There are 16 IO Size buckets correspond IO sizes 512 bytes to 16 MiBytes. The nth bucket holds
the count for IO Sizes from the previous bucket’s max size to 512 * 2n bytes.
The statpd Table
The statpd_<res>_4 table holds physical disk (PD) performance data samples.
