Uptime and certificate monitoring — know before your customers do

The problem When a website goes down, a mail server stops answering, or a TLS (Transport Layer Security) certificate quietly expires, you usually hear about it first from an unhappy customer.

How PulseWatch solves it PulseWatch checks your websites, mail servers, DNS (Domain Name System) records, ports and hosts around the clock, emails you when a check keeps failing and again when it recovers, and warns you before a certificate expires.

About PulseWatch

PulseWatch is a hosted monitor for the things customers notice first. It checks your websites, mail servers, DNS records, network ports and hosts on a schedule, around the clock. A website counts as up only if it answers the way you said it should — the status code, a response-time limit, text that must appear on the page, or a header that must be present — and every check of an https:// address also reads the TLS certificate's expiry date. When a check fails twice in a row (the threshold is adjustable) PulseWatch opens an incident and emails you once; when the check passes again it emails you that it has recovered. Certificates within 10 days of expiring (also adjustable) trigger their own warning, and a weekly email summarizes every certificate it watches. Each incident is kept with its cause and how long it lasted.

What you can do

  • Website checks that go beyond "it answered": status code, response-time limit, required page text or a required header.
  • TLS certificate expiry read on every https:// check, with a warning 10 days out (adjustable) and a weekly certificate summary email.
  • Mail server, DNS, TCP port and ping checks, each on its own schedule.
  • Flap-damped alerting: an incident opens only after two consecutive failures (adjustable), with one email when it breaks and one when it recovers.
  • Incident history with the cause and duration of every outage.
  • Alert emails carry the monitor name, the target and what failed — nothing about the monitoring service's own internals.
