Mongodb backup - filling /var/log/mongod

Hi Team,

We could see the /var/log/mongod is being filled, when the pbm agent takes backup, we run every 30 minutes and not sure is it because of the pbm agent as lot of pbm list were found on the /var/log/mongod

I am really unsure how to handle or disable the logging or avoid filling the /var/log/mongod.log
