monitore several replica sets

[arthur-c]

Hi,

I tweaked the mongodb.uri parameter in many ways but I am not able to monitore several replica sets on a same machine with one mongodb_exporter.

Should we use one exporter by RS ?

it's not supported but I think we should implement it

https://godoc.org/gopkg.in/mgo.v2#Dial . claims to support more than one DB endpoint in the URI param string. This is the package being used in at https://github.com/dcu/mongodb_exporter/blob/master/shared/connection.go#L12 , So why does it not seem to parse urls of the format "mongodb://localhost:10500,localhost:10700" properly?

I don't understand actually what should be implemented here? Are you saying that one exporter should actually connect to all replica set members and scrape all of them? Currently this line

mongodb_exporter/shared/connection.go

Line 39 in 835afca

dialInfo.Direct = true // Force direct connection

suggest that the idea was one exporter per node?
