Thank for your reply.
on Prometheus Pod 1:
alerting:
alertmanagers:
- scheme: http
path_prefix: "/alertmanager1/"
static_configs:
- targets: ['alertmanager1.monitoring.svc:9093']

alerting:
alertmanagers:
- scheme: http
path_prefix: "/alertmanager1/"
static_configs:
- targets: ['alertmanager1.monitoring.svc:9093']
I just want to implement when one alertmanager is failed, there is another
redundancy one is working well.
So may I ask what's the difference between totally 2 different deployments
and 1 deployment with 2 replicas?
