Metrics version 2

MinIO 使用 Prometheus Data Model 发布集群和节点指标。你可以使用任意抓取工具从 MinIO 拉取指标数据，以执行进一步分析和配置告警。

Version 2 端点

Metrics version 2 将指标划分为以下三个类别：

集群指标
存储桶指标
资源指标

每个 v2 端点都会返回其所属类别的全部指标。例如，抓取以下端点会返回所有集群指标：

http://HOSTNAME:PORT/minio/v2/metrics/cluster

仅访问基础端点 /minio/v2/metrics/ 也会返回集群指标。

如需更灵活的抓取方式和更广泛的指标集合，请使用 metrics version 3。现有部署仍可继续使用 version 2 指标和 Grafana 仪表板。

MinIO Grafana 仪表板

MinIO 提供两个 Grafana 仪表板，用于可视化 v2 指标。有关为 Grafana 配置兼容 Prometheus 数据源的完整说明，请参见 Prometheus 关于 Grafana 支持的文档。

可用的 version 2 指标

以下各节描述 version 2 的端点与指标。

集群指标

你可以使用以下 URL 端点抓取集群级指标：

http://HOSTNAME:PORT/minio/v2/metrics/cluster

将 HOSTNAME:PORT 替换为 MinIO 部署的 FQDN 与端口。对于使用负载均衡器管理 MinIO 节点间连接的部署，请指定负载均衡器地址。

存储桶指标

Changed in version MinIO: RELEASE.2023-07-21T21-12-44Z

存储桶指标已迁移到独立端点。

Changed in version RELEASE.2023-08-31T15-31-16Z: 你可以使用以下 URL 端点抓取存储桶级指标：

Changed in version RELEASE.2025-03-12T17-29-24Z: 出于性能原因，v2 指标最多支持 100 个存储桶。如果需要覆盖更多存储桶的指标，请改用 v3 指标。

http://HOSTNAME:PORT/minio/v2/metrics/bucket

将 HOSTNAME:PORT 替换为 MinIO 部署的 FQDN 与端口。对于使用负载均衡器管理 MinIO 节点间连接的部署，请指定负载均衡器地址。

资源指标

New in version RELEASE.2023-10-07T15-07-38Z.

你可以使用以下 URL 端点抓取资源指标：

http://HOSTNAME:PORT/minio/v2/metrics/resource

将 HOSTNAME:PORT 替换为 MinIO 部署的 FQDN 与端口。对于使用负载均衡器管理 MinIO 节点间连接的部署，请指定负载均衡器地址。

Cluster Metrics

MinIO collects the following metrics at the cluster level. Metrics may include one or more labels, such as the server that calculated that metric.
