prometheus监控常用的中间键
一、监控redis中间键
1）redis_exporter安装包下载路径
https://github.com/oliver006/redis_exporter/releases/download/v1.9.0/redis_exporter-v1.9.0.linux-amd64.tar.gz
2）解压包
tar -xf redis_exporter-v1.9.0.linux-amd64.tar.gz
mv redis_exporter-v1.9.0.linux-amd64.tar.gz redis_exporter
cd redis_exporter3) 启动redis_exporter
nohup ./redis_exporter -web.listen-address=0.0.0.0:9121 -redis.addr redis://10.2.2.236:6380 -redis.password 密码 &创建redis_exporter启动服务
$ vim /etc/systemd/system/redis_exporter.service
[Unit]
Description=redis_exporter
After=network.target
[Service]
Type=simple
User=root
ExecStart=/usr/local/prometheus/redis_exporter/redis_exporter -redis.addr -redis.password
Restart=on-failure
[Install]
WantedBy=multi-user.target4)、prometheus的配置如下
#redis配置信息
- job_name: "redis"
static_configs:
- targets: [10.2.2.236:9121]5、再grafan中导入redis dashboard
6、得到的监控数据dashboard图如下
二、rabbitmq-server 的监控
rabbitmq_exporter监控软件包下载，下载页面：https://github.com/kbudde/rabbitmq_exporter/releases
https://github.com/kbudde/rabbitmq_exporter/releases/download/v1.0.0-RC7/rabbitmq_exporter-1.0.0-RC7.linux-amd64.tar.gz
1、下载并安装部署过程

2、启动服务
RABBIT_USER=zat RABBIT_PASSWORD=zat123 OUTPUT_FORMAT=json PUBLISH_PORT=9090 RABBIT_URL=http://localhost:15672 nohup ./rabbitmq_exporter &
tail -100f nohup.out3、查看服务是否正常启动
# netstat -antpu |grep 30026
tcp6 0 0 :::30026 :::* LISTEN 28594/./rabbitmq_ex4、更改prometheus的配置文件
#rabbitmq_exporter配置信息
- job_name: "Rabbitmq_exporter"
static_configs:
- targets: [10.2.2.14:30026]
labels:
unitname: "Rabbitmq_exporter"5、重启prometheus
# systemctl restart prometheus6、查看target情况，显示已经启动
7、 再granfan上配置dashboard
最后导入显示的dashboard如下图
8、rabbitmq列队信息数监控
1）编写rule文件
- alert: Rabbitmq-queue(mq队列数)
expr: rabbitmq_queue_messages > 6
for: 2m
labels:
service_name: alertmanage-monitor
level: warning
annotations:
description: "{
{$labels.instance}}: Rabbitmq-server queue of {
{$labels.queue}}. (current value is: {
{ $value }}"
2）重启alertmanager和prometheus
# systemctl restart prometheus
# systemctl restart alertmanager
3）测试阶段我将number值调小点，此时我们可以在localhost:/alerts下看到我们的告警情况
4）与此同时我的邮箱也收到了对应的邮件
