We have many metrics under "MongoDB Metrics" & "Hardware Metrics". User will have a good idea which metrics to enable while troubleshooting certain requirements.

E.g. User is investigating current lags in the data Layer. User has to select all the metrics that would help them get the data they are looking.

We can help the customer bit more by provide buckets like.
Options ( select one )
1. Investigate Lags
2. Investigate IOPS
3. Investigate Replication
4. Investigate Search Index
... and etc..

This will pre-select certain metrics from list of Mongodb & Hardware metrics which will give them all the information needed for them to investigate. More like best practise for monitoring.
