This article uses redis_exporter prometheus grafana to monitor the Redis service. The reason is: low cost, less manual intervention, download the corresponding components directly, just add They can communicate with each other after configuration, and the visual indicators are 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

The last step! Download the json template Import
