Quick Start
This guide walks you through getting your first server under HostAtlas in roughly five minutes.
-
Sign up
Create an account at my.hostatlas.app. Free tier covers up to three servers — no credit card needed.
-
Install the agent
On the server you want to monitor, run the one-liner from Settings → Install Keys. It looks like this:
Terminal window curl -sSL https://install.hostatlas.app | sudo bash -s -- --key=YOUR_INSTALL_KEYThe installer detects your distribution, installs the agent binary to
/opt/hostatlas/, and registers a systemd unit namedhostatlas-agent. -
Wait 30 seconds for discovery
The agent connects, registers the host, and runs its initial discovery pass. You will see the server appear in the dashboard within a few seconds, and the full inventory (domains, services, containers, certs, cron, etc.) fills in over the next 20–30 seconds.
-
Explore the dashboard
Open the server and scan the tabs:
- Overview — health score, CPU/RAM/disk trends, recent events
- Domains — every vhost the agent found, with SSL status
- Services — systemd + Docker containers, running or failed
- Firewall — UFW rules and Fail2Ban jails, editable inline
- Cron Jobs — system and per-user crontabs
- Logs — on-demand access to auth.log, syslog, journal, and any app log
See Servers for the full tab reference.
-
Invite your team and set up alerts
Go to Settings → Team to invite collaborators. Then Alerts → New to create your first alert — a good starter is a
server_cputhreshold above 90% for 5 minutes, delivered to Slack or email.See Alerts for the full list of alert sources and channels.
