常用Exporter
小记一下.常见的exporter (opens new window),参考 (opens new window)

# 三 Minio监控 (opens new window),MinIO 指标 (opens new window),看板: 13502
# 3.1 MinIO给Prometheus提供了两种访问策略：
1）public方式：
给MinIO集群设置环境变量export MINIO_PROMETHEUS_AUTH_TYPE=public，Prometheus可以不通过验证访问MinIO集群； 这种方式方便简洁，本文采用这种方式。
2）访问验证token方式：
通过客户端命令mc使用命令mc admin prometheus generate <ALIAS>生成验证token，将token配置到Prometheus，Prometheus根据token信息访问集群，具体方法可参考官网。
修改MinIO集群的minio.yaml文件，修改环境变量env部分，新增Prometheus访问权限：
# 本次采用public方式
