blockbox用来探测HTTP HTTPS DNS TCP ICMP

2、配置文件 prober.yml modules: http_2xx: prober: http timeout: 5s http: valid_status_codes: [] method: GET icmp_check: prober: icmp timeout: 5s icmp: preferred_ip_protocol: "ip4" dns_examplecom_check: prober: dns dns: preferred_ip_protocol: "ip4" query_name: "www.example.com" dns_tcp_example: prober: dns dns: transport_protocol: "tcp" # defaults to "udp" preferred_ip_protocol: "ip4" # defaults to "ip6" query_name: "www.prometheus.io"

3、启动 blackbox_exporter --config.file="/etc/prober/prober.yml"

port 9115

4、prometheus配置
