01 · MONITORING

HTTP and ICMP probes. One uniform API.

HTTP/HTTPS and ICMP ping checks, extended in place with keyword matching, response validation, and SSL-certificate + domain-expiry guards. Configure every probe with the same JSON shape: type-specific fields live next to a sharedinterval_s+ region selector. Same probe definition in dashboard, REST API, and CLI.

HTTP

json

{
  "type": "http",
  "url": "https://api.example.com/health",
  "method": "GET",
  "interval_s": 30,
  "regions": ["us-west-1", "ap-southeast-1"]
}

KEYWORD

json

{
  "type": "http",
  "url": "https://example.com/",
  "expect_keyword": "Welcome",
  "expect_status": 200,
  "interval_s": 60
}

SSL + WHOIS

json

{
  "type": "http",
  "url": "https://example.com/",
  "ssl_expiry_days": 14,
  "domain_expiry_days": 30,
  "interval_s": 3600
}

HEARTBEAT

bash

# Cron job pings every 5 min
curl -sk -X POST \
  https://api.howlops.com/hb/<token>/ping

ICMP

json

{
  "type": "ping",
  "host": "203.0.113.42",

02 · ON-CALL

From signal to action in seconds.

Policy-as-code rotations. Multi-step escalation. Drag-to-override on the weekly grid. Every transition shows up on the incident timeline so the postmortem writes itself.
