# 洞察与日志

源地址列表的回源趋势与洞察页的指标和事件

## 列表 <a href="#list" id="list"></a>

源地址列表的 **24 小时回源趋势**列显示每个源地址最近 24 小时的回源请求趋势、总量和错误率，跨全部边缘和引用它的域汇总。没有流量的源地址显示 0。

## 源地址洞察 <a href="#insight" id="insight"></a>

从源地址列表的**洞察**进入，可按边缘、域和源地址（实际回源连接的 IP，域名条目列出的是解析结果）筛选，按 Host 搜索，并选择时间范围。边缘和源地址筛选作用于整页；域筛选和 Host 搜索只作用于统计卡与前三张趋势图，不作用于源站性能和事件。

<table data-search="false"><thead><tr><th width="160">指标</th><th>口径</th></tr></thead><tbody><tr><td>回源请求</td><td>该源地址的回源请求量</td></tr><tr><td>回源错误率</td><td>最终失败的请求占回源请求的比例：网络错误和源站 5xx 计入，4xx 不计；某个地址失败但重试到其他地址成功的请求算成功</td></tr><tr><td>回源重试</td><td>发生过重试的请求数，分重试后成功与重试后仍失败</td></tr><tr><td>源 IP 健康</td><td>时间范围内的剔除次数与恢复次数，跨边缘和地址累计，与下方事件逐条对应</td></tr><tr><td>错误来源</td><td>网络错误率与源站 5xx 率两条曲线。网络错误率高说明源地址本身不可达，5xx 率高说明后端出错</td></tr><tr><td>源站性能</td><td>建连耗时（含 TLS 握手）与首包耗时的 P50、P95、P99</td></tr></tbody></table>

错误率是观测口径，与[健康检查](/zh/docs/edge/endpoints/origin-address/health-check.md)的判定不同：5xx 中只有 502 Bad Gateway、504 Gateway Timeout 参与剔除判定，所以错误率升高时未必发生剔除；反过来，某个地址被剔除而请求重试成功，错误率可以是 0。

## 健康检查事件 <a href="#events" id="events"></a>

洞察页底部按时间倒序列出剔除与恢复事件：时间、边缘、类型、源地址和详情。详情是边缘生成的英文原文，写明触发的信号、阈值和剔除时长，例如 `origin api-lb ip 203.0.113.10 marked down by passive check (threshold=10, window=120s), re-enabled in 60s.`。域级剔除的事件也会列出，但不显示所属域；同一地址同一时刻的两条剔除记录，是源地址级和域级各记了一条。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://www.axisnow.io/zh/docs/edge/endpoints/origin-address/insight.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
