I recently set up a single Alertmanager instance for multiple Prometheus instances in different datacenters.

One datacenter has both an Alertmanager instance and a Prometheus instance (DC1)  The other datacenters are running only a Prometheus instance (DC2, DC3, DC4)

Each datacenter runs the same exporters under different job names and has the same set of alert rules.  Labels are different for the metrics in each of the DCs.

A space metric hit the alert criteria in DC1 and an alert was sent out.  Prometheus in DCs2-4 also detected DC1's space problem and fired an alert with the metric labels from DC1 but with DC2-4's job name.


What do you mean by this? "Prometheus in DCs2-4 also detected DC1's space problem"
