CPU pressure
Track utilization patterns, CPU model, cores, and threads that point to compute saturation.
Linux infrastructure visibility
Server monitoring without opening inbound ports.
InfraBeacon server monitoring uses a lightweight Linux agent to report CPU, memory, swap, disk, and network metrics back to your account. It is built for teams that want host-level visibility without exposing a new management surface.
Overview
What this tool is for
Use server monitoring when the question is not just whether a site responds, but whether the host behind it is under pressure. The agent reports resource data outbound, the dashboard organises current, raw, and rollup-backed metrics, and alert thresholds help catch capacity problems before they become outages.
Signals
What it monitors
Memory and swap
Watch RAM and swap movement so leaks or pressure are easier to spot.
Disk usage
See all-disk and mount-level pressure before storage exhaustion causes failures.
Network I/O
Review inbound, outbound, or combined traffic trends for unusual movement.
Agent availability
Use last-seen status to detect when the host or reporting agent stops checking in.
Recent and rollup history
Use current readings plus rollups to investigate when a problem started.
Threshold alerts
Configure downtime, CPU, memory, disk, and network alerts with recovery notices.
Controls
What you can configure
Install command
Generate a linked Linux install command from the account dashboard for each server.
Names and labels
Rename the server key and add labels so reports match how the team talks about hosts.
Token rotation
Rotate the agent token when rebuilding, moving, or replacing a monitored server.
Alert thresholds
Set duration windows for downtime and resource thresholds before notifications fire.
Metric modes
Choose RAM or RAM plus swap, all disks or a specific mount, and RX, TX, or combined network alerts.
Lifecycle controls
Update settings, check whether data has arrived, or delete old server monitors from the account.
Workflow
How it works
-
1
Add a server
Create a server monitor in the account dashboard and name the host clearly.
-
2
Run the install command
Use the generated command over SSH to install and link the Linux agent.
-
3
Read the first report
Confirm CPU, memory, swap, disk, network, and last-seen data appear in the dashboard.
-
4
Tune thresholds
Set downtime and resource alerts, metric modes, and contact routing based on how the server is used.
Use Cases
Where it fits
Small production hosts
Keep VPS and dedicated servers visible without a heavyweight observability stack.
Capacity checks
Find CPU, memory, disk, or network pressure before it explains an outage after the fact.
Operational handover
Give support and engineering teams a shared account-backed view of server health.

FAQ
Questions about server monitoring
Which operating systems are supported?
Server monitoring is designed for Linux servers that can run the InfraBeacon agent script.
Does the agent require inbound firewall access?
No. The server agent reports metrics outbound, so you do not need to open an inbound management port for InfraBeacon.
What metrics are collected?
The server monitor focuses on CPU, memory, swap, disk, mount, network, host metadata, and last-seen reporting status for operational visibility.
Can I set alerts for server metrics?
Yes. Server monitoring supports downtime, CPU, memory, disk, and network thresholds, including mode choices such as RAM only, specific disk mount, RX, TX, or combined traffic.
Can I rotate the server agent token?
Yes. Creating an agent for an existing server rotates the token and gives you a fresh install command.
