Mongo profiler output: what is the "command" operation?

We have a mongo profiler generating documents with operation type "command", e.g.

command db.collection [time]

(This is truncated output from the graylog mongo plugin)

What does the "command" type represent? What kind of internal mongo operations does it correspond to?

There doesn't seem to be anything specific in the reference manual for this other than:

system.profile.command

The command operation. If the command document exceeds 50 kilobytes, the value is a string summary of the object. If the string summary exceeds 50 kilobytes, the string summary is truncated, denoted with an ellipsis (...) at the end of the string.

I think this is for describing the original command itself though, not an operation type.

Solution

  • Following MongoDB operatons are treated as command in profiler::

     count     
 findAndModify     
 aggregate
