Stale monitoring errors? After setting a cluster with 3 shards, 3 config server with 2 mongos.



I see these errors in the monitoring agents    Failure during discovery.

What do they mean I tried to see it on the internet but no luck.
The answer came in with adding a documents into the seetings collection inside the config database.

syntax:

use config

show collections

db.settings.insert({ "_id" : "chunksize", "value" : NumberLong(64) })

db.setting.find()           ---#to check


This worked for me.
