RHEL7/8: in 'pcp dstat' output I see 'missed clock ticks' on systems with many devices

Issue

I see the following in pcp dstat output:

You did not select any stats, using -cdngy by default.
----total-usage---- -dsk/total- -net/total- ---paging-- ---system--
usr sys idl wai stl| read  writ| recv  send|  in   out | int   csw
 77  17   0   5   0|6558M  248M|  27M   20M|   0     0 | 782k  553k missed 6 ticks
 73  19   0   7   0|5066M  234M|  32M   25M|   0     0 |2454k 2113k missed 10 ticks

Is the 'missed ticks' output normal?
