Hi. I have a vanilla Prometheus setup with 50 days retention and data size of around 4.6TB for this much retention. I want to move to HA set up to avoid a single point of failure. I'm a little confused on how to approach the below points:
a) With a HA pair, does the Prometheus data necessarily be local to both the Prometheus instances? Because it would require me to provision 2 5TB disks, one for each instance. Is it a good idea to have these 2 Prometheus instances write to an NFS disk? b) With both the HA pairs scraping the same targets, how do I build a global view of these local Prometheus instances? Is federation preferable or is there any other better way to approach this? c) Since, 2 instances will be scraping the same targets, does it add any overhead to the target side?
