redis_exporter 结合prometheus 监控redis cluster集群

redis_exporter 结合prometheus 监控redis cluster集群

• 前提1：已经搭建好redis cluster集群
• 前提2：已搭建好prometheus

1、下载redis_exporter

wget https://github.com/oliver006/redis_exporter/releases/download/v1.50.0/redis_exporter-v1.50.0.linux-amd64.tar.gz

2、解压并启动

tar xf redis_exporter-v1.50.0.linux-amd64.tar.gz -C /usr/local
cd /usr/local/redis_exporter-v1.50.0
nohup ./redis_exporter -redis.addr 192.168.1.21:7001,192.168.1.22:7001,192.168.1.23:7001,192.168.1.24:7001,192.168.1.25:7001,192.168.1.26:7001 -web.listen-address :9192 -redis.password YourPassw0rdx  &

3、增加配置prometheus.yml

  - job_name: 'redis_exporter_targets'static_configs:- targets:- redis://192.168.1.21:7001- redis://192.168.1.22:7001- redis://192.168.1.23:7001- redis://192.168.1.24:7001- redis://192.168.1.25:7001- redis://192.168.1.26:7001metrics_path: /scraperelabel_configs:- source_labels: [__address__]target_label: __param_target- source_labels: [__param_target]target_label: instance- target_label: __address__replacement: 192.168.1.21:9121- job_name: 'redis_exporter'static_configs:- targets:- 192.168.1.21:9121

4、重启或者热加载prometheus

热加载需要启动时开启参数-web.enable-lifecycle

 curl -XPOST http://10.140.20.200:9090/-/reload

5、prometheus验证

6、添加grafana面板
