I am using Elastic Search Version 2.1. Now I want to set up ES Cluster (one dedicated master and one replica for now) and Monitor health status of master and replica and other metrics? I was little bit confused posting here my quereis:
- Can I use different ES versions on different machines,latest on my new machine?
- Should I use XPack or Marvel?
- I want to plot my cluster metrics in Grafana ,how can I do that?
- Can I measure how much is replication lag in master and replica?
