Know what changed
across your servers.
Before it becomes a problem.
Node Insights is a change-detection add-on that tracks software versions, disk space, RAM, and custom facts across your fleet. Every change is logged with before and after values — so you always know what happened, when, and where.
Track anything that matters across your fleet.
Built-in facts cover the common cases. Custom facts cover everything else.
Software versions
Track OS version, PHP, Python, Node.js, nginx — anything that can be queried from a shell command.
Disk space per mount
Monitor free space on every mount point. Get alerted before a filling volume takes your site down.
Free RAM
Know when memory pressure is building across your fleet — not just after a crash makes it obvious.
CPU usage
Spot sustained high CPU across nodes before it cascades into a performance incident or outage.
Custom facts
Define your own facts with a single shell command — a config file checksum, a queue depth, a process count. If you can print it, you can track it.
Threshold alerts
Set rules that fire when a fact crosses a value — disk above 85%, free RAM below 500MB — or when anything changes at all.
Up and running on your first server in minutes.
A lightweight agent does the collection. ServerVisor does the rest.
Install the agent
Drop the Node Insights agent onto each server. It runs in the background and phones home on a schedule you control.
Define your facts
Enable built-ins like OS version and disk space, or add custom facts with a single shell command. Each fact is just a key and a command that prints a value.
Watch the history build
Every check is stored with a timestamp. Browse the full change history for any node, or filter by fact to see how a value has drifted over time.
Set your alert rules
Alert when a fact changes at all, when it crosses a threshold, or only when the change looks unexpected. Your call.
Stop finding out what changed after the fact.
Node Insights is an add-on to any ServerVisor plan. Priced per node, billed monthly.
