mongostat repl-stats-indicating asterisk shows when value is zero, even if primary

    • Type: Icon: Task Task
    • Resolution: Unresolved

    • None

      I was showing mongostat to someone and they had a question about the asterisk that appears next to the insert/query/update/delete/getmore counters. Per the documentation this just indicates when the figures shown are for replicated operations on a secondary (i.e. would come from db.serverStatus().opcountersRepl rather than db.serverStatus().opcounters).

      What I've noticed is that when the value is zero it gets an asterisk even if it's the PRIMARY.

      This printing behaviour is obviously a trivial difference (zero is zero either way) but it does make it hard for people to work it out themselves what the asterisk is meant to mean. Could this be fixed?
