It would be far easier to predict replication lag and the rate at which replication lag was increasing with a few new fields in the output of mongostat.
Fields such as the following would be very useful:
- The rate of generation of op-log records on the master (in records/sec)
- The rate of processing of op-log records on the slaves (in records/sec)
