Hi all,

I keep receiving this message:
Query Targeting: Scanned Objects / Returned has gone above 1000

The problem is my Meteor website is not live yet so I don't understand why
I receive this alert ?
When I go to the Performance Advisor from Mongo Atlas, The page is empty :(

Any idea?

Hi Alain,

The meaning of the message:

Query Targeting: Scanned Objects / Returned has gone above 1000

is explained in the Query Targeting
<https://docs.atlas.mongodb.com/reference/alert-resolutions/query-targeting/>
page. This message means that you are scanning many more documents compared
to the number of documents returned by the query, meaning that the query is
executed in an inefficient manner. Typically this can be remedied by
creating a proper index. See Indexing Strategies
<https://docs.mongodb.com/manual/applications/indexes/> for more
information on how to create indexes that support your queries.

Note that if you’re an Atlas customer, you can also click on the Support
link on the Atlas page to get support specific to your deployment.

Best regards,
Kevin
