升级到 Spring Boot 版本 2 后 Prometheus 无法正常工作

Posted 2023-02-15

【中文标题】升级到 Spring Boot 版本 2 后 Prometheus 无法正常工作

【英文标题】：Prometheus not working after upgrading to Spring Boot Version 2

【发布时间】：2019-05-21 16:59:52

【问题描述】：

之前我可以在 Spring Boot 版本 2 中使用 Prometheus，没有任何问题。将 Spring Boot 版本更新到 2.1.1 后。发布我遇到以下错误。

我将 Prometheus 版本从 0.2.0 升级到 0.6.0，但仍然遇到同样的错误。

你认为 prometheus 与 Spring Boot 版本 2 不兼容吗？

问候

【参考方案1】：

不要在项目中使用 io.prometheus 依赖项，而是尝试使用 micrometer 依赖项，它将处理 Spring Boot 应用程序中 prometheus 端点的创建，因为对 prometheus 的支持是在 Spring Boot 2.X 版本中内置的

【参考方案2】：

看起来simpleclient_spring仍然是referring to Spring Boot 1.5。

您应该直接在 Spring Boot 2 应用程序中使用来自 Micrometer 的 Prometheus 支持（执行器指标的支持库）。见here。

您必须包含 micrometer-registry-prometheus 才能启用 prometheus 后端。
