Who Column Test

What if you define a "DS" condition in your analysis.cfg that references
users.rrd, something like this:

HOST=name-of-host
  DS users users.rrd:la <5 COLOR=red "TEXT=User count %V is fewer than %L"

I'm assuming that the user count shown in "[uptime]" (that goes into
users.rrd) is the same as the count of entries in "[who]".
