# 监控 (/zh/features/monitoring)
Related: [搜索](/zh/features/search.md), [搜索高亮](/zh/features/search-highlights.md), [研究索引](/zh/features/research.md), [抓取](/zh/features/scrape.md), [更快的抓取](/zh/features/fast-scraping.md), [批量抓取](/zh/features/batch-scrape.md)
Firecrawl 监控会定期执行检查，并在有内容发生变化或出现新内容时通知你或你的代理。使用 `/monitor` 可以[监视已知页面](/zh/features/monitoring-page)、[按计划爬取网站](/zh/features/monitoring-website)，或[持续运行网页搜索](/zh/features/monitoring-web-scale)，以查找与某个目标匹配的新结果。
所有监控类型都遵循相同的工作流：选择一个或多个目标，设置计划，添加一个可选的自然语言目标描述，并在有重要变化时接收 Webhook、电子邮件或 Slack 通知。本页介绍通用配置。若要查看特定目标的设置和示例，请前往 [Page](/zh/features/monitoring-page)、[Website](/zh/features/monitoring-website) 或 [全网页规模](/zh/features/monitoring-web-scale) 监控页面。
监视一个或多个已知 URL，将每次抓取与上一次快照进行 diff，并在页面发生有意义的变化时触发告警。
按计划爬取网站，检测新增、变更或移除的页面，并通知你的 Webhook 或收件箱。
定期运行网页搜索，并在出现与你的目标匹配的新结果时触发告警。
每次检查都会将页面级结果记录为 `same`、`new`、`changed`、`removed` 或 `error`。你可以在每个受监控页面处理完成时接收 Webhook，也可以在每次检查完成后接收一个 Webhook；还可以在发生更改或错误时接收电子邮件摘要、向某个频道发送的 Slack 通知，或组合使用这些通知方式。
## 目标 [#目标]
每个监控都有一个或多个**目标**。目标类型决定了每次检查会执行什么：
| 目标 | 监控内容 | 设置方式 |
| -------- | ----------- | -------------------------------------------- |
| `scrape` | 你指定的已知 URL | [页面监控](/zh/features/monitoring-page) |
| `crawl` | 通过爬取发现的每个页面 | [网站监控](/zh/features/monitoring-website) |
| `search` | 整个网页中的新结果 | [全网页规模监控](/zh/features/monitoring-web-scale) |
每个监控支持 1–50 个目标，并且你可以在同一个监控中混合使用不同的目标类型。`retentionDays` 的默认值为 `30`，最高可设置为 `365`。
每次创建调用都会返回新创建的监控，其中包含规范化后的 cron、计算得出的 `nextRunAt` 和 `estimatedCreditsPerMonth`。启用判定后，`estimatedCreditsPerMonth` 是一个上限估算值，因为判定额度只会对实际发生变化且被判定的页面计费：
```json title="Response"
{
"success": true,
"data": {
"id": "019df960-06e7-7383-9d89-82c0113dc31a",
"name": "Hacker News AI monitor",

"judgeEnabled": true,
"targets": [
{

"type": "scrape",
"urls": ["https://news.ycombinator.com"]
}
],
"webhook": null,
"notification": {
"email": {
"enabled": true,
"recipients": ["alerts@example.com"],
"includeDiffs": true
}
},
"retentionDays": 30,
"estimatedCreditsPerMonth": 2880,
"lastCheckSummary": null,
"createdAt": "2026-05-17T15:30:00.000Z",
"updatedAt": "2026-05-17T15:30:00.000Z"
}
}
```
## 目标与判定 [#目标与判定]
如果你只想在发生有意义的变化时收到告警，请添加一个通俗易懂的 `goal`。如果设置了 `goal` 但省略了 `judgeEnabled`，Firecrawl 会自动启用判定。判定会在已发生变化的页面上运行，并返回一个 `judgment`，其中包含 `meaningful`、`confidence`、`reason` 和 `meaningfulChanges`。
目标如何应用取决于目标：[page](/zh/features/monitoring-page) 和 [website](/zh/features/monitoring-website) 监控会对已发生变化的页面进行判定，而 [entire web-scale monitors](/zh/features/monitoring-web-scale#judging) 会对每个新的搜索结果进行判定。
如果你想先保存目标、暂时不对变化进行判定，请使用 `judgeEnabled: false`。只有当监控同时设置了 `judgeEnabled` 且 `goal` 非空时，判定器才会运行。
对于 `search` 目标 (全网页规模监控) ，除非你设置了 `judgeEnabled: false`，否则 `goal` 为必填。对于 `scrape` 和 `crawl` 目标，则为可选。
每次检查都会对底层抓取或爬取照常计费。如果启用了判定，判定器还会为其验证的每个已发生变化的页面额外收取 1 个额度。没有已发生变化页面的检查不会消耗判定额度。
好的目标应简短且明确：说明什么情况应触发告警，重申任何范围限制，例如前 N 项、价格、角色类型、公司、地区、主题、状态或实体，并且仅在排除条件本身属于目标意图时才写入。如果目标范围较宽泛，就保持宽泛；例如，"任何变化" 不应再加入会掩盖变化的噪声过滤条件。
例如，一个具有以下目标的监控：
```text
当与 AI 相关的新 Hacker News 故事进入前 10 时发出告警。忽略与 AI 无关的故事的变动。不对前 10 以外的变动发出告警。
```
当匹配的故事进入监控范围时，可能会生成如下这样的 `monitor.page` Webhook：
```json title="monitor.page"
{
"success": true,
"type": "monitor.page",
"id": "019df960-5f2a-75fb-a98b-bd2d32ca67d4",
"webhookId": "f1e2d3c4-0000-0000-0000-000000000000",
"data": [
{
"monitorId": "019df960-06e7-7383-9d89-82c0113dc31a",
"checkId": "019df960-5f2a-75fb-a98b-bd2d32ca67d4",
"url": "https://news.ycombinator.com",
"status": "changed",
"previousScrapeId": "019df94f-82c3-7e41-81f0-00c72b2d9c52",
"currentScrapeId": "019df960-73ee-7ac2-97a9-fb0e442c21f1",
"error": null,
"isMeaningful": true,
"judgment": {
"meaningful": true,
"confidence": "high",
"reason": "A new AI-related story entered the Hacker News top 10.",
"meaningfulChanges": [
{
"type": "added",
"after": "4. Show HN: Open-source AI coding assistant",
"reason": "This is a new AI-related story inside the top 10."
}
]
},
"diff": {
"text": "--- previous\n+++ current\n@@ -1,5 +1,6 @@\n # Hacker News\n 1. Database internals for beginners\n 2. A new approach to CSS\n 3. Building reliable queues\n+4. Show HN: Open-source AI coding assistant\n"
}
}
],
"metadata": {
"environment": "production"
}
}
```
## 调度计划 [#调度计划]
调度计划可以使用 cron 表达式或简单的自然语言文本来设置。
Cron
Text
```json
{
"schedule": {
"cron": "*/30 * * * *",
"timezone": "UTC"
}
}
```
```json
{
"schedule": {
"text": "every 30 minutes",
"timezone": "UTC"
}
}
```
支持的自然语言示例：
* `every 30 minutes`
* `every 15 minutes starting at :07`
* `hourly`
* `every 2 hours`
* `daily`
* `daily at 9:00`
* `daily at 9am`
* `daily at 5:30 PM`
* `weekly`
最短间隔为 5 分钟。API 响应始终返回规范化后的 cron 表达式。对于文本调度计划，`timezone` 用于控制像 `daily at 9am` 这类短语何时运行。文本调度计划在转换为 cron 之前，会先按监控 ID 错开分布，因此多个监控不会在同一时刻同时运行。
## 变更追踪 [#变更追踪]
[页面](/zh/features/monitoring-page) 和 [网站](/zh/features/monitoring-website) 监控默认会比较每个页面的 markdown 差异，并报告 `same`、`changed`、`new`、`removed` 或 `error`。如果你想检测**特定结构化字段** (如价格、标题、库存状态标记、列表中的条目等) 的变化，请在目标的 `scrapeOptions` 中添加 `changeTracking` 格式，并设置 `modes: ["json"]`，以启用 JSON 模式的变更追踪。
变更追踪适用于 `scrape` 和 `crawl` 目标。面向整个网页规模的 (`search`) 监控会针对新结果触发告警，而不是比较已知页面的差异。请参见 [Statuses and dedup](/zh/features/monitoring-web-scale#statuses-and-dedup)。
### Markdown 模式 (默认) [#markdown-模式-默认]
当 `scrapeOptions.formats` 仅为 `["markdown"]` 时，检查 响应中的每个已变更页面都会附带统一文本 diff，以及一个 [parseDiff](https://github.com/sergeyt/parse-diff) 风格的 AST：
```json title="Markdown-mode diff"
{
"diff": {
"text": "--- previous\n+++ current\n@@ -1,3 +1,3 @@\n # Pricing\n-Starter — $19/mo\n+Starter — $24/mo\n",
"json": {
"files": [
{
"from": "previous",
"to": "current",
"chunks": [
{
"content": "@@ -1,3 +1,3 @@",
"changes": []
}
]
}
]
}
}
}
```
### JSON 模式 [#json-模式]
传入 `changeTracking` 格式并设置 `modes: ["json"]`，同时提供一个 JSON schema (或用于描述你关注字段的 `prompt`) 。Firecrawl 会在每次检查时提取该 JSON，并输出一个**按字段区分的差异**，以字段路径作为键；此外还会附带一个包含当前完整提取结果的 `snapshot.json`，这样消费方就无需重新获取底层 抓取 结果。

"type": "array",
"items": { "type": "string" }
}
}
}
}
}
}
}
]
}
}
]
}'
```
diff 载荷使用提取结果中的 JSON 路径作为键。每个值都是一个 `{previous, current}` 对：
```json title="JSON-mode diff"
{
"diff": {
"json": {
"plans[0].price": {
"previous": "$19/mo",
"current": "$24/mo"
},
"plans[1].features[2]": {
"previous": "10 GB storage",
"current": "25 GB storage"
}
}
},
"snapshot": {
"json": {
"plans": [
{
"name": "Starter",
"price": "$24/mo",
"features": ["Up to 3 users", "Basic analytics", "Email support"]
},
{
"name": "Pro",
"price": "$49/mo",
"features": ["Unlimited users", "Advanced analytics", "25 GB storage"]
}
]
}
}
}
```
即使被跟踪的字段都没有变化，但周围的 markdown 发生了变化，JSON 模式监控仍会报告 `same`，除非你同时启用 git-diff (请参见下方的混合模式) 。该 diff 只关注 schema 中定义的字段。
### 混合模式 (JSON + git-diff) [#混合模式-json--git-diff]
如果你同时需要结构化的逐字段差异 **以及** 原始 markdown 统一 diff，请同时传入这两种模式：
```json title="Mixed target (JSON + git-diff)"
{
"type": "scrape",
"urls": ["https://example.com/pricing"],
"scrapeOptions": {
"formats": [
{
"type": "changeTracking",
"modes": ["json", "git-diff"],
"prompt": "Extract pricing tiers and headline features for each plan.",
"schema": {
"type": "object",
"properties": {
"plans": {
"type": "array",
"items": {
"type": "object",
"properties": {
"name": { "type": "string" },
"price": { "type": "string" }
}
}
}
}
}
}
]
}
}
```
随后，检查 响应会同时包含 `diff.text` (markdown sidecar) 和 `diff.json` (逐字段差异) ，以及提取得到的 `snapshot.json`：
```json title="Mixed-mode diff (JSON + git-diff)"
{
"diff": {
"text": "--- previous\n+++ current\n@@ -1,3 +1,3 @@\n # Pricing\n-Starter — $19/mo\n+Starter — $24/mo\n",
"json": {
"plans[0].price": {
"previous": "$19/mo",
"current": "$24/mo"
}
}
},
"snapshot": {
"json": {
"plans": [
{ "name": "Starter", "price": "$24/mo" },
{ "name": "Pro", "price": "$49/mo" }
]
}
}
}
```
混合模式页面会在**任一**结果形式发生变化时报告 `changed`。
## 通知 [#通知]
### Webhooks [#webhooks]
当监控配置了 `webhook` 时，Firecrawl 可以发送两种监控事件：
* `monitor.page`：每个被监控的 抓取 在 抓取 worker 中完成后发送。
* `monitor.check.completed`：在完整检查完成汇总后发送。包含检查状态和汇总计数。页面级结果请使用 `monitor.page` 事件或监控检查 API。
如果对已变更页面执行了有意义变更判定，`monitor.page` 会包含 `isMeaningful` 和 `judgment`。
```json title="Webhook config"
{
"webhook": {
"url": "https://example.com/webhooks/firecrawl",
"headers": {
"Authorization": "Bearer your-secret"
},
"metadata": {
"environment": "production"
},
"events": ["monitor.page", "monitor.check.completed"]
}
}
```
`monitor.page` 载荷：
```json title="monitor.page"
{
"success": true,
"type": "monitor.page",
"id": "019df960-5f2a-75fb-a98b-bd2d32ca67d4",
"webhookId": "f1e2d3c4-0000-0000-0000-000000000000",
"data": [
{

"checkId": "019df960-5f2a-75fb-a98b-bd2d32ca67d4",
"url": "https://example.com/blog",
"status": "changed",
"previousScrapeId": "019df94f-82c3-7e41-81f0-00c72b2d9c52",
"currentScrapeId": "019df960-73ee-7ac2-97a9-fb0e442c21f1",
"error": null,
"isMeaningful": true,
"judgment": {
"meaningful": true,
"confidence": "high",
"reason": "The page headline changed to announce a new release cadence.",
"meaningfulChanges": [
{
"type": "changed",
"before": "Welcome to our weekly update.",
"after": "Welcome to our weekly update — now with daily releases!",
"reason": "The headline changed in a way that matches the monitor goal."
}
]
},
"diff": {
"text": "--- previous\n+++ current\n@@ -1,3 +1,3 @@\n # Latest posts\n-Welcome to our weekly update.\n+Welcome to our weekly update — now with daily releases!\n"
}
}
],
"metadata": {
"environment": "production"
}
}
```
`monitor.check.completed` 载荷：
```json title="monitor.check.completed"
{
"success": true,
"type": "monitor.check.completed",
"id": "019df960-5f2a-75fb-a98b-bd2d32ca67d4",
"webhookId": "f1e2d3c4-0001-0000-0000-000000000000",
"data": [
{
"monitorId": "019df960-06e7-7383-9d89-82c0113dc31a",
"checkId": "019df960-5f2a-75fb-a98b-bd2d32ca67d4",
"status": "completed",
"summary": {
"totalPages": 2,
"same": 1,
"changed": 1,
"new": 0,
"removed": 0,
"error": 0
}
}
],
"metadata": {
"environment": "production"
}
}
```
当检查在没有页面级错误的情况下完成时，`success` 为 `true`。对于失败或部分完成的检查，它为 `false`；如果可用，`error` 会包含失败原因。
### 电子邮件 [#电子邮件]
仅当某次检查出现页面变更、新增、移除或报错时，才会发送电子邮件摘要。
```json title="Email config"
{
"notification": {
"email": {
"enabled": true,
"recipients": ["alerts@example.com"],
"includeDiffs": true
}
}
}
```
当某个监控设置了目标并启用判定后，电子邮件摘要会优先展示有意义的变更页面。如果所有变更页面都被判定为噪声，且没有新增、移除或报错的页面，则会抑制发送该电子邮件。
如果省略 `recipients`，Firecrawl 会将邮件发送给有资格接收系统告警邮件的团队成员。
你最多可以配置 25 个明确指定的收件人。
#### 收件人确认流程 [#收件人确认流程]
当有新的收件人被添加到某项监控时，Firecrawl 会向其发送一封包含确认链接的电子邮件，以确保对方明确同意接收该监控的通知。如果收件人已是团队成员，则无需确认。
### Slack [#slack]
你也可以将监控通知发送到 Slack 频道。
Slack 通知仅支持在 Dashboard 中使用。它们只能通过[监控 Dashboard](https://www.firecrawl.dev/app/monitoring)进行配置，不能通过 API 或 SDKs 配置。
要设置 Slack 通知：
1. 打开[监控 Dashboard](https://www.firecrawl.dev/app/monitoring)。你可以在创建新监控时添加 Slack 通知，也可以将其添加到已存在的监控中。
2. 在创建监控时，或选择现有监控后，滚动到 **通知** 并选择 **Slack**。
3. 系统会提示你完成 OAuth 流程。完成后，选择你希望接收通知的工作区和频道。
## 查看检查结果 [#查看检查结果]
使用 `GET /v2/monitor/{monitorId}/checks` 获取检查列表，使用 `GET /v2/monitor/{monitorId}/checks/{checkId}` 查看某次检查的详情。SDKs 默认会自动处理分页。
Python
Node
cURL
```python
from firecrawl import Firecrawl
firecrawl = Firecrawl(api_key="fc-YOUR-API-KEY")
check = firecrawl.get_monitor_check(monitor_id, check_id, limit=25, status="changed")
for page in check.pages:
print(page.url, page.status)
if page.judgment:
print(page.judgment.meaningful, page.judgment.reason)
if page.diff and page.diff.text:
print(page.diff.text)
if page.snapshot and page.snapshot.json:
print(page.snapshot.json)
```
```js
import Firecrawl from "@mendable/firecrawl-js";
const firecrawl = new Firecrawl({ apiKey: "fc-YOUR-API-KEY" });
const check = await firecrawl.getMonitorCheck(monitorId, checkId, {
limit: 25,
status: "changed",
});
for (const page of check.pages) {
console.log(page.url, page.status);
if (page.judgment) {
console.log(page.judgment.meaningful, page.judgment.reason);
}
if (page.diff?.text) {
console.log(page.diff.text);
}
if (page.snapshot?.json) {
console.log(page.snapshot.json);
}
}
```
```bash
curl "https://api.firecrawl.dev/v2/monitor/$MONITOR_ID/checks/$CHECK_ID?limit=25&status=changed" \
-H "Authorization: Bearer $FIRECRAWL_API_KEY"
```
检查列表可按检查 `status` 过滤：`queued`、`running`、`completed`、`failed`、`partial` 或 `skipped_overlap`。
检查详情响应包含 `estimatedCredits`、`actualCredits`、汇总计数以及分页的 `pages` 数组。`estimatedCredits` 是该检查预留额度的上限；`actualCredits` 是 Firecrawl 在确认有多少页面发生变化并需要判定后，最终收取的额度。使用顶层 `next` URL 获取下一页结果，其分页方式与 爬取 保持一致。你还可以按页面 `status` 过滤：`same`、`new`、`changed`、`removed` 或 `error`。每个已变更页面都包含内联 `diff` 数据；来自 JSON 模式监控的页面还会包含带有当前提取结果的 `snapshot`。

## 定价 [#定价]
监控不单独按每个监控收费。每次检查都按其执行的底层 抓取、爬取 或 搜索 计费；此外，如果启用了有效变更判定，则每个发生变更且经判定器确认的页面还会额外消耗 1 个额度。
| 组件 | 额度 |
| ------------------------------- | ---------------------------------- |
| 抓取 监控 | 每次检查每个 URL 1 个额度 |
| 爬取 监控 | 每次检查每个发现的页面 1 个额度 |
| 网页 监控 | 每次检查每 10 个结果 2 个额度 |
| 网页 监控判定 | 启用 AI 判定时，每个判定结果 1 个额度 (包含抓取和评估结果) |
| 启用有效变更判定 | 每个经判定器确认的变更页面额外 1 个额度 |
| 格式附加项 (JSON、PDF、question、增强模式等) | 与单独使用 [抓取](/zh/features/scrape) 相同 |
