That's because pmdumlog is not the best tool for this job. Partially
becuase it's command line options are not the same as "the rest", i.e
it doesn't use -a to specify archives. Try pmval -S "@whatever" with
'repeat'
i.e
pmafm Latest repeat pmval -S "@sometime" mem.freemem

You're right here. You can achieve similar effect with some extra -S
and -t options to be passed to your pmlogger. It still wouldn't
guaranty exact round time, but it will be close.

Pretty much so. You can use pmval but it's more heavy-weight compared
to pminfo and pmprobe doesn't do times, it only does one metric at the
top of the archive.
