Trying to get the different metrics of a few java apps that are exposed through LB(number of hits, incoming traffic etc) . Since it's unlikely that we will switch to spring boot 2 - with sb1 there's poor support for prometheus instrumentation. The way I see we have two options: 1. either we use log parsers directly - and get the metrics that we later aggregate what we need, or 2. we pull the LB logs - and do aggregations in that way
What's the downside of the 2nd solution?
