Server monitoring
from one small shell script.

Keep an eye on CPU, memory, root disk, load average and uptime on the Linux or BSD hosts behind your sites. A readable POSIX /bin/sh script posts metrics over HTTPS every minute with a per-server token; no daemon, root access or binary agent is needed. Tested with simulated and local agent reports, not yet on customer hosts.

How it works

A push check for the host itself, alongside the external checks on your website.

  1. Add a server in the app

    Name the host, optionally link it to a site or client, set CPU, memory and disk warning percentages and choose how many silent seconds count as a missed report.

  2. Schedule one cron line

    Copy the one-time bearer token (stored only as a SHA-256 hash) and run the plain /bin/sh script from cron or a systemd timer once a minute as an unprivileged user.

  3. Get warned when limits or reports fail

    When CPU, memory or disk reaches its threshold, or when reports stop arriving past your silence window, Beamfar alerts your routed channels and sends a recovery notice once metrics return to normal.

What you get

  • Auditable POSIX shell script

    Reads /proc/stat, /proc/meminfo, /proc/loadavg, /proc/uptime and df -Pk / (with BSD and macOS fallbacks) and posts JSON with curl.

  • Hashed per-server tokens

    Each server gets its own secret token shown once at creation or rotation; only its SHA-256 hash and short prefix are stored in PostgreSQL.

  • Threshold, silent and recovery alerts

    Separate plain-language alerts when a resource crosses your warning limit, when the host goes silent and when it reports normally again, respecting active maintenance windows.

  • Client and site scoping

    Link a server to a site or client so alerts follow client channel routing and read-only portal contacts see only their own client’s servers.

Questions about server monitoring

Does the script need root privileges or background daemons?

No. It is a short POSIX /bin/sh script that reads standard system stats and sends one HTTPS POST with curl. Run it from an ordinary user’s crontab or systemd timer.

What does the script collect?

CPU usage percentage, memory usage percentage and total megabytes, root filesystem usage percentage and total gigabytes, 1/5/15-minute load averages, uptime in seconds and optional hostname. It never reads application files, environment variables or logs.

What happens during a scheduled maintenance window?

Metrics continue to be recorded in history, while threshold, silent-host and recovery alerts are held back for the organisation, client or linked site under maintenance.

Can I rotate or revoke a server token?

Yes. Rotating a token immediately invalidates the old hash and displays a replacement token once; pausing or removing the server rejects any further metric posts.
