Linux server monitoring that tells you why the site went down

UptimePad server monitoring runs a lightweight agent on your Linux servers and reports CPU, memory, disk, and load back to the same dashboard as your uptime checks. When a group of sites on one server fail together, UptimePad links them to that server's metrics, so your alert tells you the cause and not just the symptom.

Symptom versus cause

Most monitoring tells you the symptom: a site is down. It rarely tells you the cause. When five sites on one box go red at the same minute, an uptime tool shows you five separate outages and leaves you to guess. UptimePad links sites to the server they run on, so when the server runs out of memory or pins its load average, the alert groups those sites into one incident and shows the server metric that explains it. One event, one notification, with the cause attached.

What the agent reports

The UptimePad agent is a small, single-purpose shell agent that reports core host health: CPU usage, memory, disk usage, and load average. It reports those metrics on a schedule and is rate-limited by design, so it stays light on the host and cheap to run. There is no heavyweight collector and no browser engine; it does one job and stays out of the way.

Linux first, by design

The agent targets Linux servers (Debian, Ubuntu, and the common distributions). You install it with a single command, it runs on a schedule as a cron job, and you control when you update it. Server monitoring is available from the Pro plan: 15 servers on Pro and 50 on Scale, each with the same lightweight metrics and correlation. See the setup guide for the install steps.

Pairs with the rest of your monitoring

Server metrics live next to your API, SSL, and DNS checks on one dashboard and one bill. That is the point of UptimePad: uptime, SSL, DNS, API, and server health in a single tool at indie pricing, instead of four subscriptions you have to correlate by hand. See the pricing page for the per-plan limits.

FAQ

What does UptimePad server monitoring measure?+

CPU usage, memory, disk usage, and load average, reported by a lightweight agent on the host. Those metrics are shown next to your uptime checks and are used to explain why a group of sites on the same server failed together.

Is the agent Linux only?+

Yes. The agent targets Linux servers (Debian, Ubuntu, and the common distributions) and installs with a single command. It is a deliberately small, single-purpose shell agent so it stays light on the host.

What is site-to-server correlation?+

When several monitors that run on the same server fail at once, UptimePad links them to that server and groups them into one incident with the server metric that explains the failure, instead of paging you with several separate, cause-less alerts.

Which plans include server monitoring?+

Server monitoring starts on the Pro plan with 15 servers, then 50 on Scale. The Free and Starter plans cover website, SSL, and DNS monitoring; server monitoring begins at Pro for $39 per month.

Is the agent heavy to run?+

No. It is a small, single-purpose shell agent that reports core host metrics on a schedule and is rate-limited by design. There is no heavyweight collector and no browser engine involved.

How do I install the agent?+

Install it with a single command from the dashboard (a copy-paste line), and it begins reporting on a one-minute schedule. You control when you update it. The setup guide in the docs covers the exact steps.

See the cause, not just the outage

Add a server, install the lightweight agent, and link it to the sites it runs. Server monitoring starts on the Pro plan.
