指标与告警

MinIO 使用 Prometheus Data Model 发布指标。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。

从 MinIO Server RELEASE.2024-07-15T19-02-30Z 与 MinIO Client RELEASE.2024-07-11T18-01-28Z 开始，metrics version 3 提供了更多端点。对于新部署，MinIO 建议使用 version 3。

Metrics version 2

现有部署可以继续使用 version 2 指标和 Grafana 仪表板。

Version 3 端点

对于 metrics version 3，所有指标都位于基础端点 /minio/metrics/v3 之下。你可以抓取该基础端点以一次性收集全部指标，也可以追加可选路径，仅返回特定类别的指标。

Important

本页中的 V3 指标说明可能存在缺漏、不准确或错误信息。如需最准确的指标定义，请参考 minio/minio 仓库并审阅源代码。

例如，以下端点会返回 audit 指标：

http://HOSTNAME:PORT/minio/metrics/v3/audit

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。

默认情况下，MinIO 要求在抓取指标端点时进行身份验证。如需生成所需的 bearer token，请使用 mc admin prometheus generate。你也可以将 MINIO_PROMETHEUS_AUTH_TYPE 设置为 public，以禁用指标端点认证。

相对于基础 URL，MinIO 提供以下抓取端点：

类别	路径
API	`/api/requests` `/bucket/api`
审计	`/audit`
集群	`/cluster/config` `/cluster/erasure-set` `/cluster/health` `/cluster/iam` `/cluster/usage/buckets` `/cluster/usage/objects`
调试	`/debug/go`
ILM	`/ilm`
日志 Webhook	`/logger/webhook`
通知	`/notification`
复制	`/replication` `/bucket/replication`
扫描器	`/scanner`
系统	`/system/drive` `/system/memory` `/system/cpu` `/system/network/internode` `/system/process`

各端点对应的完整指标列表，请参见 Available version 3 metrics。

如需在 MinIO Console 中启用历史数据可视化，请在 MinIO 部署的每个节点上设置以下环境变量：

将 MINIO_PROMETHEUS_URL 设置为 Prometheus 服务的 URL
将 MINIO_PROMETHEUS_JOB_ID 设置为分配给已采集指标的唯一 job ID

可用的 version 3 指标

MinIO 为集群、API 请求、存储桶以及 MinIO 服务的其他方面发布多类指标：

API 指标
审计指标
集群指标
调试指标
ILM 指标
日志 Webhook 指标
通知指标
复制指标
扫描器指标
系统指标

许多指标都包含标签，用于标识生成该指标的资源及其他相关信息。
