Monitor types
Every plan includes HTTP(S) checks with status code validation, ping for reachability, TCP port checks for databases and mail servers, and keyword checks that verify a phrase is present or absent on the page.
Pro adds JSON path assertions for APIs, response-time thresholds, custom request headers, methods and POST bodies, DNS record checks and heartbeat monitors for cron jobs and background workers.
- HTTP(S): status code and response time
- Keyword: text must, or must not, appear
- Ping: ICMP reachability and latency
- TCP port: databases, mail, game servers
- JSON path: assert on a field in the response
- Response-time threshold: alert when slow
- Custom request: headers, auth, POST bodies
- Heartbeat / cron: your job pings us
- DNS: record value and resolver time
- SSL and domain expiry: included with every HTTPS monitor
Alerts where your team already is
Connect as many channels as you like per monitor. Route different monitors to different people, silence the ones that can wait during maintenance windows, and escalate to a second person if nobody acknowledges.
Alerts include the reason for the failure, the response code, the region that detected it and a direct link to the monitor.
