The most common reason small MSPs don't have proper network monitoring isn't cost. It's the setup tax. You look at a tool like NinjaOne and see agent installs on every device. You open Syncro's documentation and find a 47-step onboarding guide. You request a Datto RMM demo and end up on a 90-minute call with a sales rep.
So you put it off. And your clients keep calling you when things break instead of you calling them.
This guide fixes that. Here's how to get real network monitoring — SNMP discovery, AI anomaly detection, alert routing, and a dashboard that shows all your client sites at once — running in under 30 minutes.
What You Need Before You Start
This isn't a long list:
- Network access to at least one client site (VPN is fine)
- SNMP community string for the devices you want to monitor — typically
publicon most routers and switches by default - Device IP ranges for your first client site — a /24 subnet takes about 60 seconds to scan
- An email address for alert notifications
No agents to pre-install. No certificates to generate. No database to stand up. If you have a network connection and an SNMP community string, you can start right now.
The Setup: Step by Step
We'll use InfraWatch for this walkthrough. If you haven't seen it yet, it's a network monitoring tool built specifically for small MSPs — SNMP-based, AI-powered, $49/month flat. No per-seat fees, no agent installs.
Go to the InfraWatch early access page and sign up. You'll get immediate access to the dashboard — no demo call, no credit card required to start.
Once logged in, you'll land on the main dashboard. It's empty right now. That changes in the next step.
Click "Add Site" in the top navigation. Give it a name (e.g., "Acme Corp — Main Office") and enter the location for reference. That's all the metadata you need — InfraWatch organizes everything else around site context automatically.
You can add as many sites as you manage. There's no per-site charge — flat $49/month covers your entire client roster.
InfraWatch uses SNMP to poll devices — the same protocol your routers, switches, and firewalls have been broadcasting on since before most of your clients' employees were born. No agent required.
Under Site Settings → SNMP, enter your community string. Most networks use public for read-only access. If your client has a custom community string configured, enter that instead.
InfraWatch supports SNMP v1, v2c, and v3. If you're not sure which version your client uses, start with v2c — it covers the vast majority of MSP environments.
Enter the subnet you want to scan — for example, 192.168.1.0/24 — and click "Discover Devices." InfraWatch will sweep the range, identify SNMP-responsive devices, and automatically pull:
- Device name and model (from
sysDescrOID) - Interface list and link states
- CPU and memory utilization (where supported)
- Uptime and system contact info
A typical /24 scan completes in under 60 seconds. You'll see your discovered devices populate in real time — routers, switches, access points, printers, servers, anything with SNMP enabled.
If you want to understand what SNMP is actually doing under the hood, our SNMP monitoring explainer covers the protocol in plain English.
This is where most MSP monitoring setups get expensive in time. Traditional tools require you to manually define thresholds for every metric, on every device, per site. CPU over 90%? Create a rule. Interface down? Create a rule. Memory above 85%? Create a rule.
InfraWatch uses AI anomaly detection instead of manual thresholds. You don't configure rules for normal ranges — InfraWatch learns what normal looks like for each device and flags deviations automatically. A switch that's pulling 80% CPU at 2am on a Tuesday gets surfaced. One that regularly runs at 75% during business hours doesn't.
Why this matters: Threshold-based alerts require constant tuning. Devices that run hot normally generate false positives constantly. Devices with unusual usage patterns get missed. AI anomaly detection eliminates both failure modes without any manual threshold configuration.
For immediate alerts (device down, interface down), go to Alerts → Notification Rules and add your email or Slack webhook. These fire instantly on hard failures regardless of the AI layer.
Repeat steps 2–5 for each client site. With the workflow established, each additional site takes about 7–8 minutes — add site, enter SNMP credentials, run discovery, confirm alert routing.
If you manage 5 client sites, you're looking at roughly 45 minutes total. If you manage 10, an hour. All sites roll up to a single multi-site dashboard so you can see your entire client portfolio at a glance without switching contexts.
This is the view that prevents Monday morning surprises.
How This Compares to Alternative Setup Processes
Setup complexity is a real differentiator in MSP tooling, but vendors rarely document it honestly. Here's what the first-setup experience actually looks like across the major options:
| Tool | InfraWatch | Syncro | NinjaOne | Atera |
|---|---|---|---|---|
| Estimated setup time (1 site) | ~30 minutes | 2–3 hours | 1–2 hours | 1–2 hours |
| Agent install required | No | Yes (per device) | Yes (per device) | Yes (per device) |
| SNMP agentless monitoring | Core feature | Available | Available | Available |
| Manual threshold configuration | Not required (AI) | Required for all alerts | Required for all alerts | Reduced with AI add-on |
| Demo call required to start | No | No | Yes (enterprise plans) | No |
| Multi-site dashboard from day 1 | Yes | Yes | Yes | Yes |
| AI anomaly detection included | Yes | No | No | Add-on only (+$95/mo) |
The agent install requirement is the primary driver of setup complexity for Syncro, NinjaOne, and Atera. You can't start monitoring a device until an agent is installed on it — which means coordinating access to client endpoints, dealing with firewall policies, and troubleshooting failed installs before you see a single metric. For a 1–20 person MSP that can't schedule a maintenance window for every client, this creates real friction.
SNMP-based monitoring sidesteps this entirely. If a device is on the network and SNMP is enabled (the default for most network equipment), InfraWatch can see it in minutes.
Common First-Setup Mistakes to Avoid
1. Using the wrong SNMP version
If discovery returns no devices, your SNMP version is usually the culprit. Start with v2c — it's the most widely supported. If you're monitoring enterprise-grade gear with security policies, you may need v3 with authentication credentials.
2. Monitoring everything before tuning what matters
Discovery will surface every device with SNMP enabled — including printers, IP phones, and ancient hardware clients forgot existed. Start with your highest-priority devices (core switches, firewalls, servers) and expand from there. Don't try to monitor everything on day one.
Avoid this: Enabling SNMP monitoring on 200 devices across 10 sites in your first session. You'll flood your alert queue with noise before the AI has enough baseline data to distinguish signal from normal variation. Add sites incrementally over the first week.
3. Setting up alerts before establishing a baseline
InfraWatch's AI layer needs 24–48 hours of data to establish a reliable baseline for each device. In the first day, you may see more anomaly flags than usual as the model calibrates. This is normal. Most will resolve themselves as the baseline stabilizes.
What You'll See in Your First 24 Hours
Within the first hour: your discovered devices, their current status, and interface statistics. Any devices that are already misbehaving will show up immediately — link flaps, high utilization, SNMP timeout errors.
Within 24 hours: the AI baseline starts forming. You'll begin seeing anomaly detection surface behavioral patterns — devices that are running differently than they were yesterday, traffic profiles that don't match historical norms.
Within a week: you'll know more about your clients' networks than most MSPs with years of ad-hoc monitoring. The AI will have flagged any slowly degrading devices before they fail, and you'll have one dashboard to check instead of five different client VPNs.
For context on what AI monitoring actually does versus threshold-based alerting, our AI network monitoring explainer goes deeper on the mechanics.
The Real Cost of Not Having This Set Up
Every hour you operate without proactive monitoring is an hour your clients can experience an outage before you know about it. For a 10-client MSP, that's roughly 10 potential blind spots at any given time.
The math on setup time isn't "30 minutes now vs. 2 hours later." It's 30 minutes now vs. the next emergency call that comes in at 6pm on a Friday because a switch started dropping packets two days ago and nobody noticed.
If you're currently running on threshold alerts — or no monitoring at all — the real cost is in the truck rolls and emergency response, not the software subscription.
Thirty minutes is a reasonable price to stop being reactive.
