Weird CPU usage

help

Hello there!

I have some problem with a weird CPU usage!

I get this profile when I stand still on in the app with one user. The only thing that is active is one subscription and no new data is put into the collection.

What do you think could be the reason? Anyone seen anything similar?

Nothing strange there. You probably haven’t enabled oplog so mongodb is being polled every 10 seconds for changes, that’s why you see the cpu working a bit about every 10 seconds. This is really little usage as well, so nothing to worry about.
