Owl v4™: Unified Cluster Monitoring with 30-Day Performance History

The Owl just leveled up.

We’re thrilled to roll out Owl v4, bringing full cluster-wide server monitoring with historical performance data up to 30 days back.

If you’ve been with us since Owl v3, you already know the drill: Smart 24/7 process monitoring, automated service recovery, and instant malware blocking, all handled quietly in the background while you sleep.

Owl’s always been the watchdog you can count on, keeping tabs on your key services:

SSH • CRON • Rspamd • Postfix • Dovecot • Pure-FTP • MySQL • Web Servers (Apache, LiteSpeed, OLS, Nginx) • DNS • Control Panel • AppCD

If something drops, Owl jumps. You get an alert, and the failed service restarts before you’ve even opened your terminal.

It also keeps an eye on CPU, RAM, Disk, Inodes, and I/O usage, firing alerts at the first sign of abuse. With the built-in MySQL Governor, it even spots and tames resource hogs to keep databases smooth and fast.

Now, Owl v4 takes that same sharp vision and gives it wings.

You can now:

View real-time and historical metrics across your entire cluster or individual servers

Switch between metrics (CPU, memory, disk, IO, traffic, and more) right from the dashboard
Explore performance trends from the last hour to the last 30 days

See top resource nodes and compare usage across servers

New CLI/WebUI tools to display cPFence Owl™ statistics summaries with custom time ranges

You can run cpfence --owl-stats 2h → shows Owl™ statistics summary for the last 2 hours.
If no window is given, it defaults to 30 minutes. Supported formats include 15m, 2h, 1d, 7d, etc.

Get a quick, clear overview of server health and performance trends right from the terminal, no browser needed. Ideal for quick checks, automation scripts, or SSH sessions.

And all that without a single API query, lightweight, zero overhead, fully local. Every data point stays inside your servers, fully GDPR and CCPA compliant. Nothing leaves your infrastructure.

Available now in both WebUI and CLI, Owl v4 comes included with your cPFence subscription, no setup, no extra license, just more insight and less guessing.

Because when the Owl sees everything, you don’t have to.
