## Blackbox Exporter — Prometheus 黑盒探测 exporter
|
||||
|
||||
**官方网址:** https://prometheus.io/docs/guides/node-exporter/
|
||||
|
||||
**类型:** 开源项目 / Prometheus Exporter
|

|

**别名:**
|

## Overview
|
||||
|
||||
Blackbox Exporter 是 Prometheus 官方提供的黑盒探测 exporter,通过 HTTP、HTTPS、DNS、TCP、ICMP 等协议探测目标端点的可用性、响应时间和 TLS 证书状态,支持细粒度的服务层监控。
|
||||
|
||||
**支持模块:**
|
||||
- `http_2xx` — HTTP/HTTPS 可用性探测
|
||||
- `https_2xx` — 仅 HTTPS 探测
|
||||
- `dns` — DNS 解析探测
|
||||
- `tcp` — TCP 端口探测
|
||||
- `icmp` — ICMP ping 探测
|
||||
|
||||
**采集指标示例:**
|
||||
- `probe_success` — 探测是否成功(0/1)
|
||||
- `probe_duration_seconds` — 探测耗时(秒)
|
||||
- `probe_ssl_earliest_cert_expiry` — TLS 证书到期时间戳
|
||||
- `probe_http_status_code` — HTTP 响应码
|
||||
- `probe_dns_lookup_duration_seconds` — DNS 解析耗时
|
||||
|
||||
**典型部署:**
|
||||
- Docker: `prom/blackbox-exporter:latest`
|
||||
- 端口:`9115`
|
||||
- Prometheus 配置需使用 `metrics_path: /probe` 和 `params: module: [http_2xx]`
|
||||
|
||||
**关键告警规则示例:**
|
||||
- 站点不可达: `probe_success == 0`(持续 2 分钟)
|
||||
- TLS 证书到期: `probe_ssl_earliest_cert_expiry - time() < 86400 * 14`(剩余 < 14 天)
