Description

What is the bug?

mimirtool alertmanager get is using /alertmanager/api/v1/alerts API endpoint and so returning 410 Gone response. It must use /alertmanager/api/v2/alerts instead.

Full error:

mimirtool: error: GET request to http://localhost:9008/alertmanager/api/v1/alerts failed: server returned HTTP status: 410 Gone, body: "{"status":"deprecated","error":"The Alertmanager v1 API was deprecated in version 0.16.0 and is removed as of version 0.28.0 - please use the equivalent route in the v2 API"}\n", try --help

How to reproduce it?

Run mimirtool with "alertmanager get"

./mimirtool alertmanager get
--address=http://localhost:9008/alertmanager
--id=Tenant1

What did you think would happen?

Mimirtool must return the list of current alerts in Alert Manager.

What was your environment?

Mimirtool running locally on a Mac (Intel) in Monolithic mode.

Any additional context to share?
