Uptime & synthetic monitoring

Know it’s down before your customers do — and why, in the same breath.

A standalone uptime tool tells you the front door is shut and leaves you to go find out why in a different product. 24Observe runs the full range of synthetic checks — websites, APIs, ports, certificates, and scheduled jobs — from more than one vantage point, and when one fails it opens a real incident right next to the logs, metrics, and traces that explain it. Detection and explanation, finally in the same place.

The uptime problem

“It’s down” is the easy half. “Why” is the half that costs you.

Uptime monitoring is a solved problem right up until the moment a check goes red — and then the tool that was so good at telling you something is wrong has nothing to say about what.

That is the structural flaw in buying uptime as a standalone product. The check fires, you get the page, and now you are in a race against your customers' patience — except your monitoring tool's job is over. It knows the endpoint returned a 500 or stopped answering; it does not know what your application logged, which dependency fell over, or which deploy went out four minutes earlier. So you leave it and go to your logging tool, your metrics tool, your tracing tool, and you start the investigation from cold, during the worst possible minutes to be context-switching between products.

There is a second, sneakier failure: the outage that is not even red. A status-code monitor that only checks for a 200 will happily report a perfectly healthy site that is, in fact, serving an error page, a maintenance placeholder, or a blank shell where the checkout used to be. The server answered, so the monitor is satisfied, and the silent outage runs until a customer complains. The tool was watching the wrong thing — the response existed, but it was wrong.

24Observe fixes both. The checks are thorough — they confirm the response is not just present but correct, and they watch the things people forget until they break, like certificates and silent cron jobs. And the failure does not dead-end in a status grid: it opens a first-class incident in the same platform that holds your logs, metrics, traces, and security detections, so the explanation is one click from the alarm and the analyst can begin investigating the cause before you have finished reading the page. Knowing it is down and knowing why stop being two products.

And because a failed check is treated as a real incident, it inherits everything the platform already does well — on-call routing, escalation, root-cause grouping, status-page updates — instead of being a second-class notification bolted onto the side.

An uptime tool that only says “down” has started your incident and abandoned you in it. The point is to land the alarm next to the answer.
The full range

Every kind of check, on one platform.

Websites, APIs, ports, certificates, and the scheduled jobs nobody else watches — covered by one monitoring surface, not a drawer full of single-purpose tools.

HTTP / HTTPS

Status codes, response time, redirects, and headers for your websites and APIs — the everyday backbone of availability monitoring.

Content & keyword

Confirm the response actually contains what it should — "Order placed," a product name, a field — so a 200 serving the wrong page is caught, not missed.

TCP & ping

Raw port reachability and ICMP checks for the services and hosts that do not speak HTTP — databases, mail, internal endpoints, network gear.

TLS certificate expiry

Track certificates and open an incident with days of lead time, so the most preventable outage on the internet never happens to you.

Cron heartbeats

Scheduled jobs ping when they finish; if the ping does not arrive in its window, an incident opens. Catch the backup that died silently.

Multiple vantage points

Checks run from more than one location and confirm across them, so a single network blip on one path does not page you for a phantom outage.

When it fails

A red check becomes an incident, not a dead end.

It opens a real incident

A failed check does not just flip a tile to red on a dashboard nobody is staring at. It opens a first-class incident — the same kind a fired detection or a metric breach opens — which means everything the platform does with incidents applies automatically. It carries a severity, it lands on the topology map against the affected service, and it begins its life as something the team is actually told about, through the channels they actually watch.

It routes to whoever is on call

The incident flows through your escalation policy and on-call schedule and reaches the right person on any of ten channels — chat, SMS, voice, a page in your incident tool of choice. If they do not acknowledge, it steps up the chain. You define who hears about what, once, and every failed check obeys it.

It groups, so one outage pages once

When a single upstream failure breaks a dozen checks, the platform recognises that the incidents share a root and collapses them into one case with a single notification. You are paged about the cause — the failed dependency — not bombarded with a dozen pages about its symptoms. The 2 a.m. storm becomes a single, legible alert.

It explains itself, and tells your customers

Because the incident lives beside your logs, metrics, and traces, the explanation is one click away and the analyst can investigate the cause. And the same incident can post automatically to a public status page your customers subscribe to — so the operator fixes the outage while the platform handles the announcements.

A worked example

The checkout that returned 200 — and lost every sale.

The exact outage a status-only monitor misses, and how a thorough check plus a connected platform turns it from a lost afternoon into a five-minute incident.

A deploy goes out at lunchtime. It does not crash anything — the site loads, the server returns a healthy 200 on every page, and a status-code uptime monitor stays a calm, satisfied green. But a front-end change quietly broke the checkout, and the confirmation page no longer renders "Order placed." Customers are clicking buy and getting a blank shell. Revenue is bleeding, and nothing is red.

Except here, the checkout monitor is a content check, not a status check. It does not merely confirm the page answered; it confirms the page still contains "Order placed." The moment that string disappears, the check fails, and an incident opens — at lunchtime, minutes after the deploy, not at five o'clock when someone notices the sales chart is flat.

The incident routes to whoever is on call and reaches them on chat and SMS. They open it and, because this is not a standalone uptime tool, the context is already there: the incident sits on the timeline beside the application logs, and a few seconds of reading shows the front-end error that started exactly when the deploy landed. There is no switch to a separate logging product, no copying timestamps; the alarm and the evidence are in the same place.

They roll back the deploy. The content check goes green again, the incident resolves, and the public status page — where the checkout component had automatically flipped to a degraded state and notified subscribers — updates itself to resolved. The customers who hit the broken window were informed; the team was paged the instant it broke, not hours later; and the entire episode, from silent failure to fix, took minutes because the monitor was watching the right thing and the platform had the answer next to the alarm.

A status-only monitor in a standalone tool would have stayed green through all of it, and the first alert would have been an angry customer. The difference is not a cleverer outage detector. It is checking for correctness instead of mere response, and landing the failure where the explanation already lives.

It is worth dwelling on how ordinary this failure mode is, because it is the one teams underestimate most. The deploys that take a site fully offline are, perversely, the safe ones — they are loud, they trip every monitor, someone notices in seconds. The expensive failures are the quiet ones: the checkout that still loads but no longer completes, the form that submits to nowhere, the API that returns a cheerful 200 wrapped around an error payload. These do not announce themselves, they are invisible to status-code monitoring, and they run for hours while a status grid glows reassuringly green. The revenue lost to a silent failure that ran all afternoon dwarfs the cost of a loud outage that was caught in a minute.

That is the real argument for content checks and for keeping uptime inside the platform that holds your logs. Checking that the response is correct, not merely present, is what surfaces the quiet failures at all; and landing each one as an incident next to the evidence is what lets you resolve it before the afternoon is gone. A monitor that watches the right thing and an investigation that starts with the answer attached are not two nice-to-haves — together they are the difference between catching the outage that actually costs you money and hearing about it from a customer.

Questions, answered

Uptime & synthetic monitoring — FAQ.

What kinds of checks can I run?
The full synthetic range: HTTP and HTTPS endpoints, raw TCP ports, TLS certificate expiry, ICMP ping for reachability, keyword and content assertions that confirm the page actually says what it should, and cron-style heartbeat monitors that alert when a scheduled job goes quiet. One platform covers websites, APIs, ports, certificates, and background jobs — you are not buying a separate tool for each.
How is a content check different from a status check?
A status check confirms the server answered; a content check confirms it answered correctly. A 200 response from a generic landing page or a "we will be right back" placeholder is a silent outage a status-code monitor sails right past. Keyword and content assertions verify the response still contains what it should — "Order placed," a product name, a JSON field — so you catch the failures that hide behind a healthy status code.
What is heartbeat (cron) monitoring?
It catches the failure of something that was supposed to happen and did not. A scheduled job — a backup, a billing run, a sync — pings a heartbeat URL each time it completes; if the expected ping does not arrive in its window, an incident opens. It is the inverse of a normal check: instead of watching for a bad response, it watches for the absence of a good one, which is the only way to catch a job that died silently.
What happens when a check fails?
It opens a first-class incident — not just a red dot on a status grid. That incident routes through your escalation policy and on-call schedule, reaches you on any of ten channels, can post automatically to a public status page, and is investigated like any other incident. A failed check is treated as seriously as a fired detection or a metric breach, because to your customers it is exactly as serious.
How fast can checks run, and from where?
Checks run on the interval your plan supports, down to high-frequency for the endpoints that matter most, from more than one vantage point so a single network blip does not page you for an outage that never happened. Confirmation across vantage points is what separates a real outage from a transient hiccup on one path.
Does it watch TLS certificates before they expire?
Yes. Certificate expiry is one of the most common, most preventable, and most embarrassing outages, and it is entirely predictable. A TLS check tracks the certificate on your endpoints and opens an incident with enough lead time to renew calmly, rather than discovering the problem from customers the morning it lapses.
How is this different from a standalone uptime tool?
A standalone uptime tool tells you the front door is down and stops there. Here, the failed check lands in the same place as your logs, metrics, traces, and security detections — so the moment the front door goes red, the logs that explain why are one click away and the analyst can investigate the cause. You are not bouncing between an uptime product and an observability product during the one moment you cannot afford the context switch.
Will one outage page me a hundred times?
No. When one root cause takes down many endpoints at once, the platform recognises that the resulting incidents share a root and collapses them into a single case with one notification. A failed upstream that breaks fifty checks pages you about the upstream, once — not fifty times about fifty symptoms.
Can I publish status to my customers?
Yes. Group your monitors into components on a public status page, let customers subscribe for updates, and have incident updates post automatically — so during an outage the operator is fixing the problem, not also hand-writing status updates. The same checks that page your team keep your customers informed.
Can I manage monitors programmatically?
Yes. Creating, updating, bulk-editing, and testing monitors is all part of the agent-programmable REST API, so you can manage uptime as code in your pipeline or let an automated agent provision checks for new services as they ship. See the API for agents.

Catch the outage early — and the silent one too.
