启动步骤
0.x.x版本使用一个exporter监控redis多实例启动方法
1.启动redis_exporter
nohup ./redis_exporter -redis.addr=redis://localhost:6379,redis://localhost:6380 -web.listen-address :50003 &
2.添加prometheus
配置(也可添加在自动发现文件中)
- job_name: 'redis_exporter'
static_configs:
- targets:
- 127.0.0.1:9121
3.重载prometheus
配置
curl -X POST http://localhost:9090/-/reload
version 1.x.x

1.x
版本监控redis多实例启动方式发生了变化,详情参考github中的pr
- 注意添加
-redis.addr
,否则会试图连接本地6379端口
