Uptime monitoring for hosting providers, before the ticket.
The hosted sites are checked from outside; a one-line agent reports the boxes from inside. You see /var at 92% while the forty tenants on that node are still loading normally.

reported by the agentFour beliefs that fill the queue
Each one sounds reasonable. Each one ends with the support queue finding out before you do.
"We already monitor everything from inside the DC."
Inside-out monitoring shares fate with what it watches — when the rack loses network, your alerting loses it too. And it measures from inside your own walls; it can never see what a customer three networks away sees.
"The sites are up, so the boxes are fine."
"Up" is a lagging indicator. A box at /var 96% serves every request right up until it serves none. By the time the sites tell you, it isn't one warning — it's the whole node, all at once.
"If our mail IPs had a problem, we'd see bounces."
The rejections happen quietly, at the far end. Mail leaves your queue fine; a listed IP just gets refused elsewhere. You find out when a customer forwards their third undelivered invoice.
"Nobody actually reads status pages."
Nobody reads them on a good day. During an incident they're the difference between one status note and forty identical tickets — and customers only need one incident to learn where to look.
"One box down is one incident" is the biggest one. On shared hosting the multiplication is brutal: one node × 40 tenants = forty simultaneous outages, forty support inboxes, forty renewal conversations — from a single full disk. The fix costs one engineer and a log rotation; finding out late costs forty customers' patience.
So the question isn't whether a box fills up this quarter. It's whether the first person to know works for you.
So what does 03:06 look like on the night /var crosses 90% — when something is watching from inside the box?↓ minute by minute
The night /var filled up
A log nobody rotated pushed /var past 90% on db-node-02 at 03:06. The forty tenant sites on that box were still serving every request, and every dashboard still read green.
That's one box saved. But a hosting fleet fails at more layers than disk — sites, certificates, domains, mail reputation.↓ every layer, one dashboard
Sites, boxes and mail IPs
Server monitoring for hosting companies means three watches at once: the tenant sites from outside, the boxes from inside, and the IPs their mail leaves from. One dashboard, grouped by rack or by client.
What your tenants notice first
One runaway log from full
Right now you would have to log in to every box to know. A one-line agent answers it continuously — CPU, memory, disk, load and network from each Linux box, every 30 seconds — so a filling /var pages your on-call while the tenants on it are still being served.
- One-line install — one
curlcommand, a systemd timer, no site downtime - Per-mount disk thresholds —
/varpages earlier than/, and each mount opens and clears its own incident - Silence counts — a box that misses three reports in a row is paged as offline, 90 seconds after the last one
Mail IPs swept across 17 zones
A listing on Spamhaus or Barracuda announces itself nowhere: mail leaves your queue clean and is refused at the far end. Blacklist monitoring for mail servers sweeps every sending domain and its IPs against 17 DNSBL zones every 15, 30 or 60 minutes, and opens a delisting runbook the moment one answers "listed".
- Domain + web IP + mail IP — one monitor covers a whole sending domain, plus up to five dedicated IPs, against all 17 zones
- Follows your infra — web IP (A record) and mail IP (MX) re-resolved every sweep, so the watch moves when you move the box
- No false alarms — reputation codes like Hostkarma NOBL and Mailspike "good" are decoded as clean, never mistaken for a listing
One paste, a rack of monitors
Onboarding a rack one form at a time is how monitoring quietly stops matching the fleet. Paste the hosted-site list, pick the check type, and the whole rack is created in one pass and filed into that rack's group — one pass per type, so uptime, SSL and domain take three. Taking the rack down on Sunday? Mute all of them in one action, across every type at once.
- Paste-to-create — bulk-create uptime, SSL, domain, malware, speed or real-user monitors, one type per pass, with the parsed list previewed before anything is made
- Per-row results — duplicates and over-limit lines come back named, row by row; the valid ones are still created
- Bulk maintenance — pause, resume or schedule a window across a whole rack from one selection

A status page on their domain
Your inbox, unless you have given them somewhere better to look. A status page on the customer's own domain — their logo, no Uptimia badge — is fed live by their monitors, so an incident becomes one note you write instead of forty tickets you answer. One such page on Basic, ten on Professional, up to 999 on Enterprise.
- Their domain, your notes — one CNAME puts a branded status page on the customer's own domain, with the "Powered by Uptimia" badge removed
- Public or private — open to their customers, or password / IP-restricted so only they see it
- Branded reports — scheduled uptime summaries as PDF, HTML or CSV; the theme that carries your colors and logo starts at Professional
Reached before the support queue fills up
One box, one mail IP or one tenant site — whichever goes, it reaches your on-call rota on the channels your team already runs incidents in.

Your fleet watched in three steps
Sites, servers and mail IPs under watch this afternoon.
Add the sites and the boxes
Paste your hosted-site list once per check type — uptime, then SSL, then domain — and drop the one-line agent onto each Linux box for CPU, disk and load.

Set thresholds & route alerts
Set disk and load thresholds per box, connect Slack and SMS, and on Professional build the ladder so on-call gets it first.
Turn on the customer-facing layer
Branded status pages on customer domains — one on Basic, ten on Professional — and monthly reports in your colors from Professional up. They hear about incidents from you.
Also included
Onboard from the API
Create monitors and status pages from your provisioning scripts — a new box spins up, one call puts it under watch.
Maintenance windows
Taking a rack offline this weekend? Schedule the window — checks pause, alerts stay quiet, nobody pages themselves.
SSL & domain expiry
Certs and registrations watched with a configurable warning window ahead of expiry. Domain monitors follow the uptime ladder to 1,000; SSL is counted with the tighter families, 100 at the top.
Escalation ladders
Route a server-down alert to on-call first, the account manager only if it's still open in 15 minutes. Ladders — and the incident grouping and one-tap acknowledgement that ride them — start at Professional; below that every alert goes to everyone at once.
Recovery notices
When a box or a site comes back, the people who were paged hear that too — no lingering 3 a.m. panic.
One account, the whole fleet
Groups keep 25 nodes and 940 sites from becoming one flat list — filter, pause or report on any rack in isolation.
Uptime monitoring for hosting providers
Uptime monitoring for hosting providers is the practice of watching every hosted site, the servers underneath them and the mail IPs customers send from — uptime, CPU, disk, load, SSL, domain expiry and blacklist listings — from one external dashboard, so the provider catches problems before support tickets arrive. One service checks the sites from the outside, an agent reports the boxes from the inside, and the results feed customer-facing status pages and reports.
The support queue finds out first
Every problem a customer notices first is a ticket, a chargeback risk and a dent in your reputation.
You catch it first
The incident becomes a line in the node's report — proof the platform is watched.
What each layer catches
Three things to watch — sites, boxes, mail IPs — covered from one place; add page speed and transactions where it matters.
Explore SSL monitoring →| Layer | What it catches | How it works |
|---|---|---|
| Uptime | Down sites, server errors | Every 30 s from Professional up, re-checked from up to 3 more regions |
| Server metrics | Full disk, load spike, offline box | Agent reports CPU/mem/disk/load every 30 s, 8 thresholds |
| SSL certificate | Expiry, broken chains | Configurable warning window, critical inside 45 days |
| Domain expiry | Lapsed registrations | WHOIS re-checked on your interval, critical inside 3 days |
| Blacklist | Mail IP listed on a DNSBL | 17 zones swept every 15–60 min, IPs re-resolved each sweep |
