   2 # PCP QA Test No. 578
   3 # Test for Bug #660497, change openfds metric to be the
   4 # largest known file descriptor used by pmcd.
   5 # This means the file descriptor can only ever increase.
   6 # The following behaviour is expected:
   7 #       the file descriptor will increase when a client or pmda connects
   8 #       the file descriptor will stay the same when a client or pmda disconnects
