Everything to get you from “what is this” to “my servers are handled.”

CleverUptime isn't just a tool — it comes with a small library. Behind every alert sits a knowledge base of hundreds of guides on Linux commands, files, and how to diagnose and fix real problems, written the way we wish someone had written them for us. It's free, there's no login, and you don't have to be a customer to read a word of it.

Straight From the Knowledge Base

A taste of what's in there — the pages people reach for at 2 a.m.:

When something's broken — symptoms, diagnosis, and the actual fix:

• A disk is failing — reading the SMART numbers before it dies.
• The disk is full — finding what ate the space when df and reality disagree.
• Out of memory — what the OOM killer did, and why.
• Load average is through the roof — what the number means and what to do.
• A RAID array went degraded — replace the right disk, not the good one.
• The server is thrashing — when swapping turns a busy box into a frozen one.

Master the everyday tools — the commands you'll use for the rest of your career:

• top and htop — reading a running system at a glance.
• df and free — disk and memory, demystified.
• journalctl — finding the one line that matters in the logs.
• ss — who's connected, what's listening, what's stuck.
• SSH — the door into every server, and how to lock it behind you.

Understand what you're running — the concepts, explained properly:

• RAID, SMART, and swap — the storage and memory ideas worth actually understanding.
• The page cache — why “free” memory isn't what you think.
• Backups — every approach, then the one simple setup you should actually use.

That's a handful out of hundreds. Browse the whole knowledge base →

Find Your Way Around

Not sure where to start? Pick the door that fits where you are:

• How It Works — the whole flow in one read: one script in, a fully-watched server out, plain-English answers when something breaks.
• Features — what CleverUptime actually watches, inside the box and from the internet.
• FAQ — the questions people actually ask before they run the script.
• Pricing — the plans, including the free one.
• Monitoring Locations — why we check your server from more than one place, and where from.

Can't find what you're after? Get in touch — we're always happy to help.

Or skip the reading and just see your own server.

One command shows you your server's health — what's fine, what isn't, and what to do about it — no signup, nothing installed.
