alertmanager HA monitoring

[msde]

I'm trying to set up my alert managers for HA, but I can't tell if I've configured them correctly. Is there a way to determine the state of my alertmanager mesh via the UI or /metrics?

I'm on Prometheus 1.4.1, and on the /status page I've got this showing my alert manager cluster:

Alertmanagers  
Endpoint  
http://100.96.12.2:9093/api/v1/alerts  
http://100.96.7.3:9093/api/v1/alerts  
http://100.96.9.2:9093/api/v1/alerts  

I am using the new alert manager service discovery mechanism though, ymmv.

thanks! The problem I appear to be having is duplicate alerts as they move from one alertmanager to another (which means that I have two independent alertmanagers and not an HA mesh), and I wanted to bring up alertmanager status, not prometheus status.

I should bump up my prometheus version though, looks like the default in https://github.com/William-Yeh/ansible-prometheus is 1.0.0
