There is nothing that will count the number of missing
values in a "file".

It is easy to count the number of missing [_FillValue]
associated with a variable. Take a look at the
examples for "num"

http://www.ncl.ucar.edu/Document/Functions/Built-in/num.shtml

  f = addfile ("...", "r")
  vNames = getfilevarnames (f)
  nVar = dimsizes( vNames )
  
  nMsgFile = 0
  
  do nv=0,nVar-1 ; loop over all file variables
     x = f->$vNames(nv)$
     nMsgFile = nMsgFile + num(ismissing(x))
     delete(x)
  end do
  
  print("nMsgFile="+nMsgFile)
