The agent watches your servers from the inside - monitors watch them from the outside, the way your users see them. Point a monitor at a URL, port, or hostname and know the moment it stops responding, slows down, or is about to expire.
Monitors check your endpoints on a schedule and alert through your escalation chains the moment something breaks.
Every monitor type shares the same setup: pick a target, set the check interval, choose who gets alerted. No separate tools for uptime, certificates, and domains.
Certificates and domains get their own deep dive on the domain & SSL expiry monitoring page.
Request any URL and verify the status code you expect comes back. Custom methods, headers, and timeouts - and every check records the response time.
Confirm anything that speaks TCP is accepting connections - databases, mail servers, message brokers, or your own custom services.
Resolve a record of any type and check the answer contains the value you expect - so a hijacked or misconfigured zone surfaces as an alert, not a mystery.
Track days-to-expiry and the issuer for every certificate. Set your own warning threshold and get alerted long before the browser warnings start.
Watch registration expiry dates along with registrar and nameserver details, so a forgotten renewal never takes your site - and your email - offline.
Every HTTP check records how long the response took, so you get a response-time history for each monitor - and you can alert on it. Set a threshold in milliseconds and find out when your site gets slow, not just when it goes dark. Most outages announce themselves as a slowdown first.
Checks run from AlertKick's monitoring locations around the world, so you see what your users see - not just what looks fine from one vantage point.
Not everything worth monitoring is on the public internet. Run an AlertKick poller inside your own network and point monitors at internal dashboards, admin panels, and private APIs - results flow into the same dashboard and alerting as everything else.
Monitor failures go through the same pipeline as every other AlertKick alert: grouped and deduplicated, delivered via email, SMS, WhatsApp, or Telegram, routed to whoever is on call, and escalated until someone responds. A monitor that fails at 3 AM wakes up one person - the right one.
HTTP, TCP, DNS, SSL, and domain monitors with configurable check intervals and timeouts, expected status codes and DNS answers, response-time tracking with millisecond alert thresholds, certificate and domain expiry warnings on your own schedule, uptime history per monitor, and delivery through your escalation chains and on-call rotations. Included on every plan, alongside the agent.
