You measured your MTTR. Now monitor and improve it.
Know about downtime before your customers do — and actually drive MTTR down. Alert24 watches your sites and APIs from 15+ global locations, pages the right person automatically, and tracks uptime, MTTR, and MTBF so you can prove reliability is getting better.
Detection alone doesn't lower MTTR
Improving mean time to resolution takes the whole loop. Alert24 covers all four stages — most monitoring tools stop at the first one.
Detect
Checks run every 30–60 seconds from 15+ locations across 6 continents. Consecutive-failure thresholds keep flapping from becoming false alarms.
Alert
A confirmed failure pages the right person through escalation policies and on-call schedules — email, SMS, voice call, Slack, Teams, and more.
Resolve
Alert24 auto-creates an incident with severity, tracks acknowledge and resolve timestamps, and keeps your status page in sync the whole time.
Learn
Analytics roll every incident into uptime %, MTTR, MTBF, and downtime cost — so you can see whether last quarter's fixes actually moved the needle.
Eleven check types. One platform.
From a simple HTTP ping to asserting a single field in an API response — monitor exactly what matters, the way it actually behaves for users.
HTTP / HTTPS
Watch websites and APIs for status codes, redirects, and response time from every region.
Ping (ICMP)
Confirm a host is reachable and measure round-trip latency over time.
TCP Port
Verify databases, mail servers, and any TCP service are accepting connections.
SSL Certificate
Get warned before certificates expire — no more surprise outages from a lapsed cert.
Domain
Alert before domain registration expires and detect unexpected DNS changes.
Keyword
Assert that expected text is present (or absent) on the page, not just that it loaded.
JSON-Path Assertion
Validate specific fields in an API's JSON response, not only its HTTP status.
Heartbeat / Cron
Catch silent failures when a scheduled job or worker stops checking in.
Browser-Based
Run real browser checks to confirm full pages and flows render as expected.
Status Page
Monitor a third-party provider's status page and react when they declare an incident.
ISP
Track connectivity and reachability across upstream networks and providers.
15+ locations. 6 continents.
Checks run from a global mesh of regions, so you can tell a real outage apart from a single-region blip and measure how your service performs for users everywhere — not just from one data center.
From red alert to resolved — automatically
A failed check isn't the end of the workflow, it's the start of one. Alert24 turns detection into a coordinated response without anyone wiring it up by hand.
- 1
A check fails past its threshold
Consecutive-failure thresholds confirm it's a real outage, not a momentary blip, before anything fires.
- 2
An incident is auto-created
Alert24 opens an incident with a severity and timestamps the moment it started.
- 3
On-call gets paged
Escalation policies and on-call schedules route the page to the right person via email, SMS, voice, Slack, Teams, and more.
- 4
Your status page updates itself
The affected component flips to its real state on your status page — no manual posting at 3 AM.
- 5
Resolution is timestamped
When the service recovers, acknowledge and resolve times are captured automatically and rolled into your MTTR.
The metrics you came here to improve
Monitoring without measurement is just noise. Alert24 turns every check and incident into the numbers that tell you if reliability is actually getting better.
Uptime %
Track availability per check and per service, with SLA tracking built in for compliance reporting.
MTTR
Every incident records started, acknowledged, and resolved timestamps — so mean time to resolution is measured, not guessed.
MTBF
See how long services stay healthy between incidents and whether reliability is trending the right way.
Downtime Cost
Translate outages into dollars so reliability work gets the priority — and budget — it deserves.
Frequently asked questions
How often are checks run?
Checks run on configurable intervals down to every 30–60 seconds. Each check runs from 15+ locations across 6 continents, and consecutive-failure thresholds let you require multiple failed checks before an alert fires — preventing flapping and false alarms.
What check types are supported?
Alert24 supports HTTP/HTTPS, ping, TCP port, SSL certificate, domain, keyword, JSON-path assertion, heartbeat/cron, browser-based, status-page, and ISP checks — so you can monitor everything from a simple website to a specific field in an API response.
How do alerts work?
When a check fails past its threshold, Alert24 auto-creates an incident with a severity and routes it through your escalation policies and on-call schedules. Notifications go out via email, SMS, voice call, Slack, Discord, Teams, Telegram, PagerDuty, Opsgenie, webhooks, and more.
Can monitoring update my status page?
Yes. Status pages update automatically from your monitoring. When a monitored service goes down, the corresponding component reflects it on your public or private status page without anyone posting an update manually.
How is MTTR calculated?
Each incident records started, acknowledged, and resolved timestamps. Mean Time To Resolution is the average time from when an incident starts to when it is resolved across your incidents. Alert24's analytics surface MTTR alongside uptime %, MTBF, and downtime cost so you can see if your reliability is improving over time.
