下载redis_exporter插件
官方没提供专门的redis_exporter，github上有人开发了
https://github.com/oliver006/redis_exporter
安装步骤:
git clone https://github.com/oliver006/redis_exporter.git
cd redis_exporter
go build .
./redis_exporter --version
编译时遇到报错
-
# go build . -
go: golang.org/x/sys@v0.0.0-20190405154228-4b34438f7a67: unrecognized import path "golang.org/x/sys" (https fetch: Get https://golang.org/x/sys?go-get=1: dial tcp 216.239.37.1:443: connect: connection timed out
可以先设置 GOPROXY 变量
export GOPROXY=https://goproxy.io
go build .
启动redis_exporter
redis_exporter 可以支持监控单实例和多实例。如果监控一个redis 可以使用
nohup ./redis_exporter -redis.addr 127.0.0.1:6379 &
监控多个redis 则需要先启动exporter
nohup ./redis_exporter &
然后在prometheus.yml 的文件中添加
-
- job_name: 'redis_exporter_targets' -
static_configs: -
- targets: -
- redis://10.9.106.217:6379 -
- redis://10.9.106.217:6381 -
metrics_path: /scrape -
relabel_configs: -
- source_labels: [__address__] -
target_label: __param_target -
- source_labels: [__param_target] -
target_label: instance -
- target_label: __address__ -
replacement: 10.9.11.22:9121 -
-
## config for scraping the exporter itself -
- job_name: 'redis_exporter' -
static_configs: -
- targets: -
- 10.9.11.22:9121
重新reload配置
sudo curl 'http://localhost:9090/-/reload' -X POST
采集到的redis监控数据
配置grafna
-
配置prometheus数据源，添加prometheus插件
-
下载redis仪表盘模板,选择prometheus数据源，然后上传json文件，下载地址: https://grafana.com/grafana/dashboards/763/revisions
