Linux server monitoring with one lightweight agent
One curl command installs a lightweight Rust agent that streams CPU, memory, disk, network, processes, package vulnerabilities, and security events from every Linux server to a real-time fleet view.
Know every Linux server like you SSH-ed into it
Most teams monitor Linux servers reactively: top and df when something feels slow, a scramble through journalctl when it breaks, and no idea which of last month's CVEs apply to the packages actually installed on each box. A traditional linux monitoring tool fixes part of that — the metrics — and leaves the processes, packages, and security events for other tools and other bills.
AllStak monitors Linux servers with a single lightweight Rust agent installed by one curl command. It collects CPU, memory, disk, network, load, and processes; inventories installed packages and matches them against known vulnerabilities using OSV and CISA KEV; and captures host security events via auditd. Releases are signed and the agent auto-updates safely. Every server appears in a fleet view, and each host gets its own dashboard with a health score, events, and timelines — on the same platform as your errors, logs, and alerts.
Everything the agent watches on a Linux server
One install per server and AllStak covers metrics, processes, vulnerabilities, and security events — the full picture a sysadmin would build by hand, kept live.
Core system metrics
CPU, memory, disk, network, and load averages stream in real time, with history so you can tell a one-off spike from a trend heading toward an outage.
Process visibility
See the processes running on each server and which are consuming CPU and memory, so finding the culprit no longer requires SSH and top.
Package inventory & CVE matching
The agent inventories installed packages and matches them against known vulnerabilities using OSV and CISA KEV, so you know which servers carry which CVEs without running a separate scanner.
Host security events
Security-relevant host activity is captured via auditd and surfaced on the host timeline, so suspicious behaviour on a server shows up next to its metrics, not in a separate tool.
Fleet view
All your Linux servers in one list with their status and health, so you can scan the whole fleet in seconds and jump straight to the host that needs attention.
Per-host health, events & timelines
Each host gets a dashboard with a rolled-up health score, an event feed, and timelines — so the question "what changed on this server?" has an answer you can scroll.
From curl to fleet visibility in minutes
- 1Install with one command
Run a single curl command on each Linux server to install the lightweight Rust agent. No configuration files to hand-write and no dependency stack to manage.
- 2Metrics and inventory start flowing
The agent immediately streams CPU, memory, disk, network, load, and processes, inventories installed packages, and begins matching them against OSV and CISA KEV.
- 3Watch the fleet in real time
Open the fleet view to see every server's health at a glance, then drill into any host for its live charts, events, timelines, and security findings.
- 4Let the agent keep itself current
The agent auto-updates from signed releases, so your fleet stays on the latest version without you re-running installs across every server.
Why teams monitor Linux servers on AllStak
- One curl command per server — from zero to live metrics, package inventory, and security events in minutes, with no exporter stack to assemble.
- A lightweight Rust agent keeps the footprint small, so monitoring never becomes the load you are monitoring.
- CVE matching against OSV and CISA KEV on the actual packages installed per server — vulnerability awareness without a separate scanner.
- auditd-based host security events live next to metrics and processes, so reliability and security are reviewed on one timeline.
- Signed releases and safe auto-update keep a large fleet current without manual upgrade rounds.
- One platform and one bill for servers, errors, logs, traces, uptime, and security — with SAR pricing, a free tier, and data residency in Saudi Arabia.
Linux monitoring FAQ
How do I install the AllStak Linux agent?
With one curl command per server. The install script sets up the lightweight Rust agent, connects it to your project, and metrics, processes, package inventory, and security events start streaming within minutes — no configuration files to write by hand.
How much overhead does the agent add to my servers?
The agent is written in Rust and built to be lightweight, with a small footprint on each server. It is a single binary rather than a stack of exporters and collectors, so the cost of monitoring stays small relative to what it tells you.
Does AllStak detect vulnerabilities on my Linux servers?
Yes. The agent inventories the packages installed on each server and AllStak matches them against known vulnerabilities using OSV and the CISA Known Exploited Vulnerabilities catalog. It also captures host security events via auditd, so package risk and live host activity appear on the same dashboard.
How does AllStak compare to Datadog for Linux server monitoring?
Datadog charges per host and then per additional product, so servers plus logs plus security become separate line items that grow with the fleet. AllStak is all-in-one with predictable SAR pricing: server metrics, vulnerability matching, security events, errors, logs, traces, and uptime on one platform and one bill — and you can start free.
Is there a free tier, and where is my server data stored?
Yes — you can start free and connect your first Linux servers at no cost, then scale on predictable SAR pricing. AllStak offers data residency in Saudi Arabia, so your server metrics, package inventory, and security events stay in-Kingdom, with dashboards in both English and Arabic.
