Website monitoring features

Everything PageWarden watches, in one place

Seven monitor types, incidents you can trust, multi-region confirmation and downtime alerts to every channel you already use. This is the full tour of PageWarden website monitoring features.

All-in-one monitoring

Seven monitor types

Uptime, SSL and domain are on every plan. Keyword, port and DNS are on paid plans. Ping is on Starter and up.

Everything one monitor is watching

Uptime monitoring

Uptime monitoring

HTTP and HTTPS checks on a schedule. PageWarden classifies each check as up, degraded (responded but slow) or down (bad status, timeout, or a DNS or connection failure).

Redirects are followed, and checks use a real browser-like user agent so they are not blocked. Check intervals are plan-based, down to 60 seconds.

Checks as often as every 60 seconds

SSL certificate monitoring

SSL certificate monitoring

Track certificate expiry and validate the chain. Know before a cert lapses and takes the site down with it.

SSL certificate monitoring is available on every plan, including Free.

Watches the chain and the expiry date, on every plan

Domain expiry monitoring

Domain expiry monitoring

WHOIS-based tracking of domain registration expiry. The classic silent outage is a forgotten renewal, caught early here.

Domain expiry monitoring is available on every plan, and is distinct from DNS record monitoring below.

Tracks the registration expiry, on every plan

Keyword monitoring

Hobby and up

Keyword and content monitoring

Assert that a page contains, or does not contain, specific text. Catch a broken checkout, a leaked error string, a missing Add to cart, or a defacement.

It is an uptime check that reads the body, not just the status code.

Alerts when expected text goes missing, or bad text appears

Port monitoring

Hobby and up

TCP port monitoring

Monitor a raw TCP service on a specific port: SMTP, POP3, IMAP, FTP, a database, or a game server. Up or down on connectivity.

Works with any TCP port

DNS monitoring

Hobby and up

DNS record monitoring

Verify that DNS records resolve as expected (A, AAAA, CNAME, MX, TXT, NS) with an optional expected value. Catch a bad DNS change or a hijack.

Watches A, AAAA, CNAME, MX, TXT and NS records

Ping monitoring

Starter and up

Ping (ICMP) monitoring

Test raw host reachability over ICMP, with no port and no HTTP. It separates a host being down from a service being down, useful for devices and servers that expose no TCP service.

Ping runs from the prober regions and is loss-aware: all replies is up, partial packet loss is degraded, and no replies is down.

Tells a down host apart from a down service

Incident management

Incidents, auto-grouped

Two consecutive failed checks open an incident, dated at the first failure. Two consecutive successes resolve it at the recovery time. No per-check spam: one incident per outage, with status, started, resolved, duration, the failing target, the latest error and the in-window check results. Incidents can be acknowledged.

A transient or blocked failure is retried once before it is recorded, so a momentary blip does not open a false incident.

Multi-region uptime monitoring

Confirmed from multiple regions

Before PageWarden records a retryable down, it re-checks from multiple regions and a quorum decides. Prober regions are New York, San Francisco, Frankfurt, Singapore and Sydney, plus the primary vantage. Multi-region confirmation protects every plan.

Starter and Pro scan from every selected region continuously, with per-region uptime history (24h and 7d), a per-region response chart, a live region map, a per-monitor region picker, and affected-region detail on regional incidents.

Downtime alerts

Alerts everywhere

Notifications on incident open and recovery, with strict no-duplicate sends and a retry ladder. Every channel has a send-test button.

Email is on every plan, with multiple recipients per monitor and the diagnosis included when available.

Webhook, Discord, Slack and Telegram are on paid plans. Webhooks can be HMAC-signed with an X-PageWarden-Signature header. SMS is on Pro.

Status pages

A status page for every incident

Publish a branded public status page for any set of monitors, so people can check for themselves instead of asking you.

Live status and history

Current status plus 24-hour, 7-day and 30-day uptime, and a 90-day daily uptime bar. Recent incidents are listed automatically.

Embeddable badge

Every status page comes with an embeddable badge you can drop into your own site or README.

White-label on Starter and up

One page on the Free plan, more as you scale. Starter and up can drop the default footer and use a domain of your own.

Root-cause context

Plain-English diagnosis

When an incident opens, PageWarden adds a short hypothesis about the likely cause to the incident and the alert, clearly marked verify before acting. A quiet assist on Starter and Pro, not a headline.

Organize and operate

Groups, tags and control

Monitor groups and tags with a dashboard filter bar (search, group, status, tag). Per-check enable and disable lets you pause a single check, such as SSL during a migration, without deleting the monitor. Configurable check intervals down to 60 seconds on Starter and Pro.
