What PingDog monitors

Seven check types, including three that nobody else offers. Built for the modern stack — APIs, blockchain nodes, and AI agents.

🌐
HTTP / HTTPS
Status code, response time, and body match. Catch 5xx errors, wrong content, and slow responses before your users do.
🔌
TCP Port
Is the port open? How fast does it connect? Monitor databases, mail servers, and raw TCP services.
🔎
DNS Resolution
Resolution time, resolved IPs, and NXDOMAIN detection. Know when DNS propagation breaks your service.
🔒
SSL Certificate
Certificate validity and days until expiry. Get alerted 30 days before your cert expires — not after it already has.
⛓️
RPC Health
Block height, sync status, and staleness detection. Know if your node is stuck or 200 blocks behind without checking manually.
🤖
A2A Agent
Discovers the agent card, verifies required fields, and pings the agent endpoint. Catch broken AI agents before they fail in production.
🛠️
MCP Server
Connects via WebSocket, sends a tools/list request, and verifies the tool catalog returns. Know your MCP server is alive and responding.

No more false alarms

PingDog checks from multiple continents simultaneously. We only declare DOWN when the majority agrees. A transient blip in Singapore does not wake you up at 3am.

  • 4 regions Need 3+ failures to declare DOWN
  • 3 regions Need 2+ failures to declare DOWN
  • Free tier 2 regions — both must fail
