Hello all,
I've a basic prometheus baremetal setup and it seems the recommend way to setup HA is with a pair of prometheus servers scraping the same targets. I've few questions on this: a) With a HA pair, the prometheus data will be local to both the prometheus instances. Is it a good idea to have these 2 prometheus instances write to some sort of a network mounted filesystem like NFS / GlusterFS filesystem,so that the data is identical for both the prometheus instances ? Has anyone tried this ? b) AFAIK, with both the ha pairs scraping the same targets, how do i build a global view of these local prometheus instances? Is federation the only way with another Prometheus instance scraping the ha pair ? c) When the 2 ha pair scrape the same targets, are the metric values identical or slightly different, due to time offsets between the scrapes ? What happens if my scrape interval for prometheus A is 15sec and Prometheus B is 16 sec, then do i still need to dedup, since the values will be different ? What's the right strategy to dedup the metrics ? -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
