二.json-exporter配置
1.Dockerfile
FROM prometheuscommunity/json-exporter:latest USER 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
modules:
default:
headers:
X-Dummy: my-test-header
metrics:

1.prometheus.yml
global:
scrape_interval: 15s
evaluation_interval: 15s
scrape_configs:
- job_name: json_exporter
metrics_path: /probe
file_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"]}
]四.grafana
上边的都配置好，把自己的peometheus数据源添加到grafana中，就可以设置自己想要的监控界面了
