我用普罗米修斯配置了警报管理器，并根据普罗米修斯界面发出警报。但是没有显示松弛消息，我想知道是否需要配置 ufw 或者我是否错过了任何其他配置。
alertmanager 服务正在运行，prometheus 显示“正在启动”。
这是我的配置文件：
alertmanager.yml：
global:
slack_api_url: 'https://hooks.slack.com/services/my_id_removed...'
route:
group_by: ['alertname']
group_wait: 30s
group_interval: 5m
repeat_interval: 1h
receiver: 'slack_general'
receivers:
#- name: 'web.hook'
# webhook_configs:
# - url: 'http://127.0.0.1:5001/'
- name: slack_general
slack_configs:
- channel: '#alerts'
send_resolved: true
inhibit_rules:
- source_match:
severity: 'critical'
target_match:
severity: 'warning'
equal: ['alertname', 'dev', 'instance']
普罗米修斯.yml：
global:
scrape_interval: 10s
evaluation_interval: 15s # Evaluates rules every 15s. Default is 1m
alerting:
alertmanagers:
- static_configs:

static_configs:
