MMS Agent VERY high data usage

I have an application which really does not have a lot of writes to a mongo replica set yet there is a constant 500Kb/s network traffic between members of the set, even over night when there is absolutely no traffic on the application. Surely this is not the heartbeats? What could possibly be using so much bandwidth?

SEE EDIT, this is not the replset but rather the MMS monitoring which is running on the same machine

Solution

  • Thanks to the guys at mongo, it turns out that it is the log capture functionality.

    If you are experiencing the same thing, log onto MMS and edit your host and turn off logs, bandwidth drops immediately.
