build user: root@ab86c672c33a
build date: 20190302-14:57:04

All program in docker.

prometheus.yml

# my global config
global:
  scrape_interval:     10s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 10s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).
# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets: ['192.168.0.238:9093']

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"
  - "/docker/prometheus/sd_config/alert_rules/alertmanager_rules.yml"

alertmanager_rules.yml

groups:
 - name: alert-name
   rules:
   - alert: InstanceDown # 告警名称
     expr: up == 0 # 告警的判定条件，参考Prometheus高级查询来设定
     for: 2m # 满足告警条件持续时间多久后，才会发送告警
     labels: #标签项
       team: node
     annotations: # 解析项，详细解释告警信息
       summary: "{{$labels.instance}}: has been down"
       description: "{{$labels.instance}}: job {{$labels.job}} has been down "
       value: {{$value}}

but I can see any rules in web.
http://192.168.0.10:9090/alerts
I get "No alerting rules defined "

http://192.168.0.10:9090/rules
I get "No rules defined "

In alertmanager web
http://192.168.0.238:9093/#/alerts
I get "No alerts found"

It makes more sense to ask questions like this on the prometheus-users mailing list rather than in a GitHub issue. On the mailing list, more people are available to potentially respond to your question, and the whole community can benefit from the answers provided.

in alertmanager_rules.yml

value: {{$value}}
