安装Prometheus

wget https://github.com/prometheus/prometheus/releases/download/v2.34.0/prometheus-2.34.0.linux-amd64.tar.gz

tar -zxvf prometheus-2.34.0.linux-amd64.tar.gz

mv prometheus-2.34.0.linux-amd64 prometheus

vim prometheus.yml

# my global config
global:
  scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # 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:
           - localhost:9093
# Load rules once and periodically evaluate them according to the global "evaluation_interval".
rule_files:
        - "rules/host_rules.yml"
  # - "first_rules.yml"
  # - "second_rules.yml"
# A scrape configuration containing exactly one endpoint to scrape:
# Here it"s Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"
    # metrics_path defaults to "/metrics"
    # scheme defaults to "http".
    static_configs:
      - targets: ["localhost:9090"]
  - job_name: "agent-web01"
    static_configs:
      - targets: ["172.31.32.104:9100"]
  - job_name: "agent-web02"
    static_configs:
      - targets: ["172.31.29.223:9100"]
  - job_name: "java"
    static_configs:
      - targets: ["172.31.29.223:8100"]
    metrics_path: "/actuator/prometheus"

创建规则

mkdir -p /root/prometheus/rules

cat host_rules.yml

groups:
- name: 系统资源告警规则
  rules:
  - alert: CPU使用率告警
    expr: 100 - (avg by (instance)(irate(node_cpu_seconds_total{mode="idle"}[1m]) )) * 100 > 80
    for: 1m
    labels:
      user: prometheus
      severity: warning
    annotations:
      description: "服务器: CPU使用超过80%！(当前值: {{ humanize $value }}%)"
  - alert: 内存使用率告警
    expr: (node_memory_MemTotal_bytes - (node_memory_MemFree_bytes+node_memory_Buffers_bytes+node_memory_Cached_bytes )) / node_memory_MemTotal_bytes * 100 > 80 
    for: 1m
    labels:
      user: prometheus
      severity: warning
    annotations:
      description: "服务器: 内存使用超过80%！(当前值: {{ humanize $value }}%)"
  - alert: 磁盘告警规则
    expr: 100 - (node_filesystem_free_bytes{mountpoint="/",fstype=~"ext4|xfs"} / node_filesystem_size_bytes{fstype=~"ext4|xfs"} * 100) > 70
    for: 1m
    labels:
      user: prometheus
      severity: warning
    annotations:
      description: "服务器: 磁盘使用超过70%！(当前值: {{ humanize $value }}%)"

启动

nohup ./prometheus &

效果图

安装alertmanager

wget https://github.com/prometheus/alertmanager/releases/download/v0.24.0/alertmanager-0.24.0.linux-amd64.tar.gz

tar -zxvf alertmanager-0.24.0.linux-amd64.tar.gz

mv alertmanager-0.24.0.linux-amd64 alertmanager

vim alertmanager.yml

具体可以去企业微信后台查找相关参数

global:
  resolve_timeout: 2m
  wechat_api_url: "https://qyapi.weixin.qq.com/cgi-bin/"
  wechat_api_secret: "<你的企业微信secret>"
  wechat_api_corp_id: "<你的企业微信id>"
route:
  group_by: ["alertname"]
  group_wait: 10s
  group_interval: 10s
  repeat_interval: 1h
  receiver: "wechat"
receivers:
- name: "wechat"
  wechat_configs:
  - send_resolved: true
    to_party: "1"
    agent_id: "<你的企业微信应用id>"
templates:
  - "/alertmanager/*.tmpl"

yaml语法检查

./amtool check-config alertmanager.yml

企业微信报警模板

cat wechat.tmpl

 {{ define "wechat.default.message" }}
{{- if gt (len .Alerts.Firing) 0 -}}
{{- range $index, $alert := .Alerts -}}
======== 异常告警 ========
告警名称：{{ $alert.Labels.alertname }}
告警级别：{{ $alert.Labels.severity }}
告警机器：{{ $alert.Labels.instance }} {{ $alert.Labels.device }}
告警详情：{{ $alert.Annotations.summary }}
告警时间：{{ $alert.StartsAt.Format "2006-01-02 15:04:05" }}
========== END ==========
{{- end }}
{{- end }}
{{- if gt (len .Alerts.Resolved) 0 -}}
{{- range $index, $alert := .Alerts -}}
======== 告警恢复 ========
告警名称：{{ $alert.Labels.alertname }}
告警级别：{{ $alert.Labels.severity }}
告警机器：{{ $alert.Labels.instance }}
告警详情：{{ $alert.Annotations.summary }}
告警时间：{{ $alert.StartsAt.Format "2006-01-02 15:04:05" }}
恢复时间：{{ $alert.EndsAt.Format "2006-01-02 15:04:05" }}
========== END ==========
{{- end }}
{{- end }}
{{- end }}

启动

nohup ./alertmanager &

安装Grafana

wget https://dl.grafana.com/oss/release/grafana-8.4.6.linux-amd64.tar.gz

tar -zxvf grafana-8.4.6.linux-amd64.tar.gz

mv grafana-8.4.6.linux-amd64 grafana

配置未更改，走的默认，也可以根据具体情况做相应的配置改动

启动

nohup ./grafana &

配置数据源为Prometheus

因为在本地，所以首选localhost

保存并测试

导入配置
