The state of monitoring
Every option asks you to compromise.
Legacy tools are heavy
Zabbix, Nagios and Centreon are powerful — and famous for the setup and upkeep they demand. Standing them up is a project of its own.
Cloud monitoring gets expensive
Usage-based pricing scales in ways that are hard to predict. The bill grows with every host, metric and custom event.
Simple uptime tools hit a ceiling
Great for a homelab ping check, but thin once you need real infrastructure visibility, teams and per-customer separation.
Why Demerzel
Answers, not dashboards to configure.
The outcomes you actually want — without the operational tax of legacy tooling.
Know before your customers do
See what needs attention today, ranked by severity — not an alphabetical list of hostnames.
Alerts that respect your sleep
Notify on real threshold crossings, once per situation. No storms, no 3 a.m. noise for a blip.
One dashboard per customer
Give each client their own view. Their data never mixes with anyone else’s.
Never chase an expired certificate
TLS certificates are tracked by soonest expiry, so a renewal is a task long before it’s an incident.
What it does
The essentials, done well.

FAQ
Questions, answered honestly.
Do I have to install or maintain any servers?
No. Demerzel is a fully managed cloud service. You install one lightweight agent on the machines you want to monitor; storage, processing and updates all run on our side.
How does monitoring work?
A small agent runs on each server and reports metrics and status to Demerzel over HTTPS. It is read-only and outbound-only — it never opens an inbound port or accepts remote commands.
Where is my data hosted?
In the European Union, on OVHcloud infrastructure in Roubaix, France. Your data does not leave the EU.
Is there a free trial?
Yes — a 14-day free trial on every plan, with no credit card required.
How is pricing calculated?
A predictable flat price per plan, based on the number of hosts you monitor. No usage-based billing and no surprise overages.
Can I monitor several customers from one account?
Yes. The Business plan adds multi-client separation and role-based access control, built for MSPs and agencies.
Start monitoring in minutes, not weeks.
No servers to maintain. No painful setup. See your whole infrastructure in one place.
