This article uses redis_exporter prometheus grafana to monitor the Redis service. The reason is: low cost, less manual intervention, and direct downloading of the corresponding The components can communicate with each other simply by adding configurations, and the visual indicators are also relatively comprehensive.

Recommended (free): redis

The following is on a Linux machine with redis installed

1. redis_exporter

Download the program compressed file

wget https://github.com/oliver006/redis_exporter/releases/download/v0.28.0/redis_exporter-v0.28.0.linux-amd64.tar.gz

Unzip

tar zxf redis_exporter-v0.28.0.linux-amd64.tar.gz

cd into the directory

cd redis_exporter-v1.15.0.linux-amd64

Run the redis_exporter program directly Adding & means running in the background. The /redis_exporter & command accesses the localhost:6379 of the local machine by default. You need to specify the redis usage of other machines./redis_exporter ip:port &

./redis_exporter &

2, prometheus

The first step is to download the file as usual. The unzipped file (v2.7.1) can be modified to the version that needs to be installed. You can click https://github.com/prometheus/prometheus/releases to find the corresponding version. No.

wget https://github.com/prometheus/prometheus/releases/download/v2.7.1/prometheus-2.7.1.linux-amd64.tar.gz

tar zxf prometheus-2.7.1.linux-amd64.tar.gz

cd enters the directory and you will find a prometheus.yml configuration file. This configuration file corresponds to the service name, monitoring address and port of each service.

vim prometheus.yml

Open the configuration file and add the configuration of redis_exporter communication

   - job_name: 'prometheus'
     static_configs:
     - targets: ['localhost:9090'] #程序在本机开通的端口号 默认9090
  - job_name: 'redis'
    static_configs:
    - targets:
      - "IP:9121" #（安装redis_exporter的IP）

Run ps: Check if there is any process occupying port 9090

./prometheus &

http://ip:9090/targets Check if Success

3, grafana

No more nonsense

  wget https://dl.grafana.com/oss/release/grafana-6.0.0-beta1.linux-amd64.tar.gz

tar zxf grafana-6.0.0-beta1.linux-amd64.tar.gz

cd grafana-6.0.0-beta1

./grafana-server start

After startup: http://ip:300 Default User: admin, password: admin Then find data sources on the left

Configure the Url corresponding to your program address
