I found that resolved alerts will be sent repeatedly, so I used some return values to do hash.
Like some alerts' info about Node, I used alertname๏ผ instance, startsAt this three value to do hash and achieve alert uniqueness.
def hash_value(labels, starts):
hash_str = labels.get("alertname", '') + labels.get("instance", "") + starts
return hash(hash_str)v1.0
