I have just started the three MongoDB replica servers.
- I do not understand what is this screw value what it should be on which server?
- Which values should I monitor
I have taken 2 screenshots shown below for Primary Mongo DB Server, Secondary Mongo DB Server & Arbiter Mongo DB Server respectively.
## Primary Mongo DB Server --- Location : Singapore ##
## Secondary Mongo DB Server --- Location : North Virginia ##
## Arbiter Mongo DB Server --- Location : Singapore ##
As far as I understand they are in sync very well and all of them are AWS Instances.
- I need to know how and what should I monitor?
- What kind of maintenance activities should I do & how?
Please feel free to let me know if you need any further info. Thanks in advance!!
