actually i got it wrong:
  val < 0: all
  val == 0: disable
  val > 0: store the previous val+1 inputs


its a factor of:
- how much disk space you're prepared to allocate
- how big your configuration is (after bzip compression)
- how far back you want to keep records for
- how "busy" the cluster is over that period
- how important the information is to you :-)

as a rough guide, i'd use something like:
error = -1
warn = 400
input = 200
