Hardware Monitoring for MSPs: The RMM Blind Spot

If you manage 50+ machines as an MSP, you're probably using an RMM tool for patch management, remote access, and software deployment. These tools are excellent at what they do. But they have a critical blind spot that falls under hardware monitoring: they don't read physical sensors, they don't capture per-process history, and they don't decode the Windows Event Log when a client machine BSODs at 3 AM.

After 8 years working with MSPs and IT teams in Copenhagen and remotely with international fleets, we've seen the same story repeat: a client's machine shows green in the RMM dashboard right up until it blue-screens from thermal shutdown. The RMM knew the machine was online. It had no idea the GPU was running at 103°C — or that Cyberpunk2077.exe had been the load on the GPU when the temperature climbed.

The Blind Spot in Every RMM

Standard RMM agents collect:

• Windows event logs (raw, undecoded)
• Installed software
• Disk space
• CPU/RAM usage percentages
• Network status

What they don't collect:

• CPU/GPU actual temperatures (learn what's safe in our CPU temperature guide)
• Fan speeds and failure detection
• VRAM usage and GPU power draw
• VRM temperatures (the #1 silent killer)
• Disk temperatures (SSDs throttle at 70°C)
• Chipset and ambient temperatures
• Per-process history (which application caused the spike, which app is leaking RAM)
• Auto-decoded BSODs (Event ID 41/1001/219 translated into plain language with sensor context)
• Windows Event Log analysis (WHEA-Logger trends that predict RAM failure weeks ahead)

This means your RMM shows a machine as "healthy" right up until the moment it blue-screens from thermal shutdown — and then provides no diagnostic context for what caused the crash.

Real Example: The Silent VRM Failure

A creative agency with 12 workstations running 3D rendering. Their RMM showed all machines green — online, patched, disks not full.

What the RMM didn't show: one machine's VRM (Voltage Regulator Module) was running at 112°C because a fan had partially seized. The VRM provides power to the CPU — when it fails, the motherboard dies. This exact scenario plays out regularly in creative studios where sustained rendering pushes every component to its limits.

The machine crashed during a client deadline. The motherboard was destroyed. Total cost: replacement parts + emergency labor + lost project time = ~$2,000.

A monitoring agent costing $20/machine/month would have caught this weeks earlier — and the alert that fired would have read: "VRM has been climbing 1.5°C/week for the last 6 weeks; CPU fan #2 RPM dropped from 1,800 to 1,200 in the same window. Likely partial fan seizure. Schedule inspection in the next 14 days." Not a temperature reading. A diagnosis.

What Real Hardware Monitoring Looks Like

GGFix deploys a lightweight agent on each machine that reads actual sensor data via LibreHardwareMonitor — the same open-source library that powers many popular hardware monitoring tools.

Every minute, the agent reads:

• All CPU core temperatures + package temp
• GPU edge temp, hotspot temp, VRAM temp
• Fan speeds (every fan the motherboard exposes)
• VRM and chipset temperatures
• Disk temperatures (per SSD/HDD)
• Power draw, clock speeds, load percentages
• RAM usage
• Top 25 processes by CPU and RAM (with window titles)
• Last 24 h of critical Windows Event Log entries (BSODs, disk errors, driver failures, app crashes, unexpected shutdowns)

Every 5 minutes, it aggregates this data and sends it to the cloud. Claude AI analyzes the trends, decodes Event Log entries into plain language, and fires alerts when patterns indicate problems — not just when static thresholds are breached. A critical event (BSOD, unexpected shutdown, GPU hotspot above 110°C) reaches the on-call technician via Telegram in under 10 seconds.

See our Telegram hardware alerts setup walkthrough for the alert delivery side and the memory leak detection on Windows guide for the per-process intelligence layer that no RMM provides.

How to Close the Hardware Visibility Gap

The solution is layering hardware sensor monitoring on top of your existing RMM:

1. Audit your fleet's thermal state — before adding any tools, pick 5 client machines and manually check CPU/GPU temps with HWiNFO. You'll likely find at least one running hotter than expected. This confirms the gap.
2. Deploy a sensor-reading agent alongside your RMM. Look for one that reads actual hardware sensors (temperatures, fan RPM, SMART data, power draw), captures per-process history, and parses the Windows Event Log — not just OS-level metrics.
3. Route alerts to your PSA — hardware alerts should create tickets in your existing workflow, not require checking another dashboard. Telegram for human-attention alerts, webhook for ticketing automation.
4. Bill it as a value-add — GGFix at $20/machine/month ($200/year, two months free) is easy to pass to clients as "proactive AI hardware monitoring with auto-decoded crash diagnosis." Your RMM handles software. A hardware monitoring agent handles the physical layer. Together, you see everything.

According to Gartner's IT infrastructure research, organizations that adopt predictive monitoring reduce unplanned downtime by up to 50%.

The Business Case for Internationally Distributed MSPs

For an MSP managing 100 machines anywhere in the world:

• One prevented motherboard failure = ~$1,300 saved
• One prevented GPU failure = ~$2,000–$4,000 saved
• One prevented BSOD-driven Windows reinstall (when the actual cause was failing RAM you could have caught from WHEA trends) = 4–6 hours of technician time saved per incident
• Zero emergency site visits for preventable thermal issues — critical when client sites are in a different city or country than your operations base

For MSPs supporting remote workforces or geographically distributed clients (a freelancer pool across the US, a remote-first agency with team members in three time zones, a small holding company with offices in two countries), the hardware visibility gap is widest exactly where you have the least physical access. A monitoring agent that runs as a Windows Service and pushes everything to a cloud dashboard removes the geography problem entirely.

In our experience, the monitoring pays for itself the first time it catches a problem — and most fleets have at least one machine silently overheating right now.

Frequently Asked Questions

Q: Can GGFix replace my RMM tool?

No, and it's not designed to. GGFix focuses exclusively on hardware sensor monitoring, per-process intelligence, and Windows Event Log decoding — the layer your RMM does not cover. Your RMM handles software management, patching, remote access, and scripting. They work together: your RMM shows software health, GGFix shows hardware health and the which app caused this context for crashes.

Q: How do I deploy GGFix across a fleet of client machines?

Generate enrollment tokens in the GGFix dashboard, then deploy the agent via your RMM's remote execution feature (PowerShell one-liner). The installer runs silently and takes about 30 seconds per machine. For MSPs managing large fleets, batch deployment through your existing tooling is the fastest approach.

Q: Does GGFix work with ConnectWise, Datto, NinjaOne, N-Able, or Datadog?

GGFix is RMM-agnostic. It runs as an independent Windows service alongside whatever RMM or observability agent you use. Alerts can be routed via webhook to your PSA or ticketing system (ConnectWise Manage, Autotask, etc.) for seamless integration into your existing workflow, while critical alerts go via Telegram to whoever is on-call.

Q: What is the overhead of running another agent on client machines?

The GGFix agent uses approximately 15 MB of RAM and negligible CPU. It reads sensors and the top 25 processes once per minute and uploads aggregated data every 5 minutes. The agent has zero impact on user-facing performance and runs as a background Windows service.

Q: How is this different from infrastructure monitoring like Datadog or PRTG?

Datadog and PRTG are infrastructure-monitoring platforms designed primarily for servers, networks, and cloud workloads. They can monitor Windows endpoints via agents, but the agents do not surface deep hardware sensor data, per-process history, or auto-decoded BSODs out of the box — those have to be wired up with custom sensors and parsing logic. GGFix is purpose-built for Windows endpoint hardware health from day one, at a fraction of the seat price.

Q: How do MSPs typically discover hardware problems today?

In our experience, most MSPs discover hardware issues only when a client reports symptoms — "my computer is slow," "it keeps crashing," "the fans are loud." By that point, the damage is often done. The predictive maintenance approach flips this: monitoring catches degradation weeks before symptoms appear, turning emergency repairs into scheduled maintenance during the next site visit — and reducing the after-hours phone calls that destroy MSP margins.

Q: How does pricing scale for an MSP with 100–200 client machines?

GGFix uses simple per-machine pricing: $20 per machine per month monthly, or $200 per machine per year (two months free). At 100 machines that's $1,667/month annual or $2,000/month monthly — less per machine than the average emergency callout for a single hardware crash. Most enterprise RMMs that include any kind of hardware visibility require multi-year commitments at significantly higher per-seat costs; GGFix has no minimum commitment, no per-technician seat fees, and a 3-day free trial with 3 machines included.
