二.json-exporter配置

1.Dockerfile

FROM prometheuscommunity/json-exporter:latestUSER root
RUN mkdir -p  /opt
WORKDIR /opt
COPY  config.yml /opt/

2.config.yml

根据上边返回的json数据，制定自己需要的监控模版，部署json-exporter 10.111.11.11:7979

三.prometheus配置

1.prometheus.yml

global:scrape_interval: 15s evaluation_interval: 15sscrape_configs:- job_name: json_exportermetrics_path: /probefile_sd_configs:- files:- 'redis-shake.json'relabel_configs:- source_labels: [__address__]target_label: __param_target- source_labels: [__param_target]target_label: instance- target_label: __address__replacement: 10.111.11.11:7979 # json-exporter地址

2.redis-shake.json

单独的文件配置可实现动态加载，同时可添加自定义的标签在文件中

[
# labels为自定义的标签，targets为部署各个redis-shake地址
{"labels": {"env-1":"团队1"},"targets": ["http://10.111.11.12:8888"]},
{"labels": {"env-1":"团队2"},"targets": ["http://10.111.11.12:8889"]},
{"labels": {"env-1":"团队3"},"targets": ["http://10.111.11.12:8890"]}
