# allocated_fh = float(handle_metrics[0])
# allocated_unused_fh = float(handle_metrics[1])
# max_fh = float(handle_metrics[2])
# num_used = allocated_fh - allocated_unused_fh
system.fs.file_handles.allocated = allocated_fh
system.fs.file_handles.allocated_unused = allocated_unused_fh
system.fs.file_handles.in_use = num_used / max_fh
system.fs.file_handles.used = num_used
system.fs.file_handles.max = max_fh
