ACS Monitor Know what's broken before your customers call.
ACS Monitor is a self-hosted network and infrastructure monitoring platform built by MSPs, for MSPs. SNMP polling, service checks, auto-discovery, custom dashboards, and multi-channel alerting — all from a single one-command install.
Deploy in minutes, monitor everything, and catch issues early — without the complexity of traditional tools.
Built for real-world MSP environments. No credit card required.
Know a site is failing before your customer calls
Smart thresholds, consecutive failure checks, and multi-channel alerts mean you hear about problems first -- not from a frustrated client on the phone.
One install, one dashboard, every client
SNMP devices, service monitors, and network health across all your clients in one place. Scoped views keep everything separated.
From zero to monitoring in under 10 minutes
One command installs everything. All services configured, monitoring running, and ready before your coffee gets cold.
Alerts that actually tell you what's wrong
Device, metric, threshold, and severity in every alert. Recovery notifications when it's resolved. Delivered via email, SMS, Slack, or webhooks.
Designed for real MSP headaches
Every feature exists because we hit the same problems you do. Here is how ACS Monitor fixes them.
The problem
Customers calling before your alerts fire
The fix
Smart thresholds with consecutive failure checks eliminate false positives. You get alerted when something is genuinely wrong -- before anyone else notices.
The problem
Jumping between three tools to find what's broken
The fix
SNMP polling, service monitors, and network diagnostics in one place. No more tabbing between platforms to piece together what went wrong.
The problem
Spending half a day setting up monitoring for a new client
The fix
One command. Done in minutes. The installer handles everything, and auto-discovery finds devices and services on the network automatically.
The problem
Dashboards that look great but don't actually help
The fix
25 widget types designed for the data you actually need. Status grids, alert feeds, throughput charts, SSL trackers -- all drag-and-drop, all real-time.
One platform. Everything you need.
SNMP, service checks, dashboards, alerting, and network tools -- all in one place, all self-hosted.
Stop juggling tools just to see what's broken
SNMP polling, service checks, website monitoring, and auto-discovery in one platform. No more switching between three different tools to get the full picture of a client's network.
- SNMP v1/v2c/v3 with custom OID polling and MIB resolution
- 11 monitor types: HTTP, Ping, TCP, SSH, DNS, SMTP, FTP, POP3, IMAP, MySQL, HTTPS
- Website monitoring: track uptime, response times, SSL expiry, and content changes across client sites
- Auto-discovery: ping sweep, SNMP probe, and service detection in one scan
Know exactly what's wrong, not just that something is
Every alert includes the device, IP address, metric, threshold breached, and severity level. When the issue resolves, you get a recovery notification with both the trigger and resolution timestamps. Consecutive failure checks prevent false alarms -- you only get woken up when it actually matters.
- Threshold rules with consecutive failure counts to prevent false alarms
- Multi-channel delivery: email, SMS, Slack, and custom webhooks
- Auto-escalation, acknowledge workflow, and recovery notifications
Dashboards that actually help you work
Not eye candy -- practical layouts with the data you need to make decisions. 25 widget types, drag-and-drop, auto-refreshing, and shareable with clients via a single link.
- Charts, gauges, grids, heatmaps, status cards, SSL trackers, and more
- Drag-and-drop layout with auto-saving positions
- Shareable via unique link -- no login required for viewers
Diagnose issues without leaving the platform
Ping, traceroute, port scan, DNS lookup, SSL check, WHOIS, and HTTP header inspection -- all from the browser with live streaming results. No more SSH sessions just to run a traceroute.
- 7 diagnostic tools with live streaming results
- MIB manager with upload, parsing, and dependency resolution
- Subnet scanning with auto-import of discovered devices and services

Deploy in MinutesBuilt from real MSP experience
We run an MSP. We built the monitoring tool we actually wanted to use. Every feature exists because we needed it in the field.
Scoped Client Views
Give each client their own view without spinning up separate instances. Per-client logins, dashboards, and device groups -- all from a single install.
White-Label Ready
Present it as your own monitoring platform. Self-hosted on your server, your domain, your branding. No third-party logos or vendor lock-in.
Rapid Deployment
New client? New server? Running in minutes, not days. One install command sets up everything, creates your admin account, and activates your license automatically.
"We built ACS Monitor because the tools we used were either too complex, too expensive, or required days of setup just to get basic monitoring working. We needed something that an engineer could deploy in minutes and a client could actually understand."

Frequently asked questions
Straight answers. No marketing waffle.
ACS Monitor is a self-hosted network and infrastructure monitoring platform built by MSPs, for MSPs. It combines SNMP device monitoring, service checks, website monitoring, auto-discovery, multi-channel alerting, and built-in network diagnostic tools into a single platform that deploys on your own Linux server with a one-line install.
ACS Monitor polls SNMP devices (v1/v2c/v3), runs 11 service monitor types (HTTP, Ping, DNS, SSH, SMTP, TCP, FTP, POP3, IMAP, MySQL, HTTPS), monitors websites for uptime, response times, SSL expiry, and content changes, auto-discovers networks, receives SNMP traps, and ingests webhooks. It also includes built-in diagnostic tools like traceroute, port scanning, DNS lookup, SSL checks, WHOIS, and HTTP header inspection. All from a single self-hosted platform.
Managed Service Providers (MSPs) who monitor multiple client networks, and IT teams who need self-hosted monitoring without cloud dependencies. Per-client scoped views, one-command deployment, and white-label hosting are built specifically for MSP workflows. If you manage infrastructure for other businesses, this is built for you.
Under 10 minutes from sign-up to live monitoring. Create an account, add a server, and paste one install command. The installer handles all services, database, admin account creation, and license activation. You will be adding devices before your coffee gets cold.
AlmaLinux 9, Rocky Linux 9, RHEL 9, Ubuntu 22.04+, Debian 12+, Fedora 38+, CentOS 9 Stream, and Raspberry Pi OS 12+ (ARM64). The installer auto-detects your OS, installs all dependencies, and configures everything automatically.
Your existing monitoring continues without interruption. You just cannot add new devices or monitors until you upgrade or remove some. No data loss, no downtime, no surprises.
Yes. Scoped user views let you create dedicated accounts for each client, locked to specific device groups and dashboards. Clients log in and see only their own infrastructure, alerts, and search results. You can also create per-client notification channels.
Completely. ACS Monitor is self-hosted on your own server. Your monitoring data never leaves your infrastructure. The only communication with our platform is periodic license validation and anonymous usage heartbeats (device count, monitor count, app version).
Email, SMS, Slack, and custom webhooks. You can configure per-channel and per-device notification rules, set up escalation chains, and receive recovery notifications when issues resolve. Each notification includes the device, metric, threshold, and severity level.
Yes. 25 widget types including charts, gauges, status grids, heatmaps, alert feeds, SSL trackers, and more. Drag-and-drop layout with auto-saving, auto-refreshing data, and shareable via unique links -- no login required for viewers.
