搬运工-compose.yml: 这是docker-compose运行prometheus,node-exporter和alert-manager服务。所有服务都运行良好。甚至普罗米修斯目标菜单中的健康状况都显示正常。
version: '2'
services:
prometheus:
image: prom/prometheus
privileged: true
volumes:
- ./prometheus.yml:/etc/prometheus/prometheus.yml
- ./alertmanger/alert.rules:/alert.rules
command:
- '--config.file=/etc/prometheus/prometheus.yml'
ports:
- '9090:9090'
node-exporter:
image: prom/node-exporter
ports:
- '9100:9100'
alertmanager:
image: prom/alertmanager
privileged: true
volumes:
- ./alertmanager/alertmanager.yml:/alertmanager.yml
command:
- '--config.file=/alertmanager.yml'
ports:
- '9093:9093'
prometheus.yml
这是带有目标和警报目标集的prometheus配置文件。 alertmanager目标网址工作正常。
global:
scrape_interval: 5s
external_labels:
monitor: 'my-monitor'
# this is where I have simple alert rules
rule_files:
- ./alertmanager/alert.rules
scrape_configs:
- job_name: 'prometheus'
static_configs:
- targets: ['localhost:9090']
- job_name: 'node-exporter'
static_configs:
- targets: ['node-exporter:9100']
alerting:
alertmanagers:
- static_configs:
- targets: ['some-ip:9093']
alert.rules: 只需一个简单的警报规则即可在服务停止时显示警报
ALERT service_down
IF up == 0
alertmanager.yml
这是在发出警报时发送消息。

问题: 所有容器都工作正常我无法弄清楚确切的问题。我真的错过了什么。检查prometheus中的警报显示。
警报 没有定义警报规则
答案 0 :(得分:3)
您的./alertmanager/alert.rules
文件未包含在您的docker配置中,因此容器中没有该文件。您需要将它添加到prometheus服务中:
prometheus:
image: prom/prometheus
privileged: true
volumes:
- ./prometheus.yml:/etc/prometheus/prometheus.yml
- ./alertmanager/alert.rules:/alertmanager/alert.rules
command:
- '--config.file=/etc/prometheus/prometheus.yml'
ports:
- '9090:9090'
并且可能在prometheus.yml
内提供绝对路径:
rule_files:
- "/alertmanager/alert.rules"
您还需要确保警报规则有效。有关详细信息和示例,请参阅prometheus docs。你alert.rules
文件应该是这样的:
groups:
- name: example
rules:
# Alert for any instance that is unreachable for >5 minutes.
- alert: InstanceDown
expr: up == 0
for: 5m
一旦有多个文件,最好将整个目录添加为卷而不是单个文件。
