    Description

      Hi,

      When running mongotop without any parameter, it shows 10 lines of activity.

      mongotop 
      

      ns    total    read    write    2018-03-20T14:59:21+11:00
      admin.system.roles      0ms     0ms      0ms                             
      admin.system.version      0ms     0ms      0ms                             
      dat.test      0ms     0ms      0ms                             
      local.startup_log      0ms     0ms      0ms                             
      local.system.replset      0ms     0ms      0ms                             
      tab0.test      0ms     0ms      0ms                             
      tab1.test      0ms     0ms      0ms                             
      tab2.test      0ms     0ms      0ms                             
      tab3.test      0ms     0ms      0ms                             
      tab4.test      0ms     0ms      0m
      

      However, when using the parameter --json the number of collections shown are many more.

       mongotop --json
      

      {"totals":{"admin.system.roles":{"total":{"time":0,"count":0},"read":{"time":0,"count":0},"write":{"time":0,"count":0}},"admin.system.version":{"total":{"time":0,"count":0},"read":{"time":0,"count":0},"write":{"time":0,"count":0}},
      ......
      "tab98.test":{"total":{"time":0,"count":0},"read":{"time":0,"count":0},"write":{"time":0,"count":0}},"tab99.test":{"total":{"time":0,"count":0},"read":{"time":0,"count":0},"write":{"time":0,"count":0}}
      

      Is there any known limitation, any hard limit about the --json parameter? I can't see any, but wanted to be sure.

      Thanks in advance.
