Stale monitoring errors?

Question

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.

Answer 1

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.

Answer 2

From those error messages, I can see that there is "name resolution" problem. Like dcixcfitrmdbs03.dcicloud.local what points to "localhost" address obviously.
