The board that defined cheap computing just got expensive. As The Register reported, the 2 GB Raspberry Pi 4 — once the poster child of the $35 computer — now costs $67.50, with the Pi 5 taking a $12.50 bump and buyers being urged to consider older models or less RAM.
For a hobbyist, that's an annoying headline. For an MSP running fleets of Raspberry Pis as remote monitoring probes, SNMP pollers, and edge appliances across dozens of client sites, it's a hardware line item that doubled overnight. And it lands on top of the cost pressure MSPs already feel everywhere else: per-device licensing, per-agent seats, and the labor hours burned on tool-hopping instead of actual fixes.
Here's the uncomfortable part: most MSPs can't say precisely how many probes they have deployed, which ones are healthy, or what each one truly costs them. The price hike just made that blind spot expensive.
The Real Cost Isn't the Board — It's Everything Around It
The probe fleet math nobody updated
Think about how most MSPs actually do client-side monitoring. PRTG wants a remote probe at each site to reach devices behind the firewall. Zabbix wants a proxy. Some shops run LibreNMS pollers, Uptime Kuma instances, or homegrown ping boxes on Pis because they're silent, sip power, and — until last week — cost $35.
Run the numbers for a 30-client MSP: 40-60 boards deployed at $35 each is $1,400-$2,100 in hardware. At $67.50, that's $2,700-$4,050 — before the SD card, PSU, case, and the two to four technician hours to image, deploy, and map checks onto each one. At a blended $85/hour, the labor cost per probe already dwarfs the hardware. The price hike just made a cost structure nobody was tracking suddenly visible.
The failure mode every MSP tech knows
The Pi itself rarely dies. The SD card dies. Constant small writes chew through consumer flash, a power blip corrupts the filesystem, and the probe goes dark in a closet in a client's office.
Now think about what that means: when your monitoring probe fails, your monitoring fails with it. No checks fail, because nothing is left to check. No alerts fire, because nothing is left to fire them. You find out when the client calls — "wasn't your company watching this?" — three hours after their switch flapped. A silent probe turns a 20-minute incident into an SLA breach, and no report in any of your tools will ever show you the gap, because during the gap, none of them were listening.
Tool sprawl multiplies the hardware bill
If your stack looks like NinjaOne or ConnectWise for RMM, PRTG or Zabbix for monitoring, Freshservice or Zendesk for the helpdesk, and a separate patching product, every one of those tools wants its own agents, collectors, and sometimes its own on-site presence. That's how you end up with two or three boxes plugged into a client's switch instead of one — each an unmonitored single point of failure, each a rebuild waiting to happen.
Then there's the license stack. For a 1,200-endpoint MSP, it's routine to see RMM at ~$3.50 per device, monitoring licenses on top, helpdesk seats at $20-$40 per agent, and patching as yet another SKU. Add it up and you're commonly at $8-$15 per endpoint per month across four or five vendors — $115,000 to $215,000 a year — paying again and again for data that never actually joins up.
Why the gaps exist
Point tools were built standalone and got integrations bolted on later through scheduled API syncs. That's why your PSA learns about a monitoring alert on a 15-minute import cycle, why SLA reporting means exporting two CSVs into Excel and hoping the timestamps line up, and why the tech who gets paged at 2 a.m. has to be the human middleware between systems that should already talk to each other.
The measurable damage: inflated MTTR from swivel-chair work, alert fatigue from uncorrelated notifications, a full day of every month lost to manual SLA reports, and burnout among the technicians you can least afford to lose.
How AlertMonitor Changes the Equation
AlertMonitor was purpose-built for the MSP model — multi-tenant from day one — and it attacks both halves of this problem: the hardware footprint and the labor.
One platform, fewer appliances
Monitoring, RMM, helpdesk, patching, network topology mapping, and intelligent alerting in one product means one agent story and one lightweight collector per client site instead of one probe per tool. An MSP running three products that each want an on-site presence can typically cut the probe count by half or more on consolidation — savings that, after this price hike, pay back the difference between a $35 board and a $67.50 board several times over.
Monitor the monitors
In AlertMonitor, your Pi probes, edge appliances, and servers are monitored devices like everything else: disk usage, temperature, service health, uptime. When that SD card starts throwing I/O errors or the root filesystem climbs past 85%, an alert fires — routed to the right technician per client, with that client's SLA thresholds already attached — while the probe is still alive and fixable. Automated remediation can restart a hung collector service before anyone's morning is ruined.
The old way: PRTG shows a wall of down sensors, you VPN in, SSH to the probe, discover the card is dead, rebuild the image, re-add devices, update the spreadsheet. Two to four hours, and the client was blind the whole time.
The AlertMonitor way: the probe's own disk health trend triggers an alert days before failure, a ticket is auto-created with the device context attached, and the card gets swapped on the next scheduled site visit. The client never goes blind.
From alert to ticket without a human in the loop
Because the helpdesk and the monitoring live in the same system, a downed switch at Client B becomes a ticket in seconds — carrying the device, its topology position, its recent history, and the client's SLA clock. Per-client alert routing means the right tech gets it, not everyone. Nobody triages, nobody correlates, nobody re-types context from one tool into another.
SLA reporting that doesn't require Excel archaeology
Alerts, response times, tickets, and patch state share one data store. The compliance report your biggest client asks for quarterly is a filter, not a two-day project.
Practical Steps You Can Take This Week
1. Audit your probe fleet. List every Pi and edge appliance per client site, then SSH into each and check its actual health:
#!/bin/bash
# probe-health.sh — run on a Raspberry Pi monitoring probe
echo "=== $(hostname) ==="
echo "-- Temperature --"
vcgencmd measure_temp 2>/dev/null || cat /sys/class/thermal/thermal_zone0/temp
echo "-- Root filesystem --"
df -h /
echo "-- Storage errors (last 20) --"
dmesg | grep -iE "mmc|sd[a-z]|i/o error" | tail -20
echo "-- Uptime --"
uptime
echo "-- Monitoring services --"
for svc in zabbix-proxy2 snmpd ntp; do
if systemctl is-active --quiet "$svc"; then
echo "$svc: OK"
else
echo "$svc: DOWN"
fi
done
2. Schedule the check so a failing card surfaces on your terms, not during an outage:
# /etc/cron.d/probe-health — daily health log on the probe itself
0 6 * * * root /usr/local/bin/probe-health.sh >> /var/log/probe-health.log 2>&1
3. Check disk headroom across the servers you manage. This is the check AlertMonitor runs continuously for every client — here's the manual version from a jump host:
# Flag any server drive with less than 15% free across a client site
$servers = Get-Content "C:\Scripts\clientA-servers.txt"
Get-CimInstance -ComputerName $servers -ClassName Win32_LogicalDisk -Filter "DriveType=3" |
Select-Object @{n='Server';e={$_.PSComputerName}},
@{n='Drive';e={$_.DeviceID}},
@{n='FreeGB';e={[math]::Round($_.FreeSpace/1GB,1)}},
@{n='TotalGB';e={[math]::Round($_.Size/1GB,1)}},
@{n='FreePct';e={[math]::Round(100*$_.FreeSpace/$_.Size,1)}} |
Where-Object { $_.FreePct -lt 15 } |
Sort-Object FreePct
4. Find your overlapping agents. On any endpoint, see which monitoring and RMM agents are installed — every hit from a different vendor is a license you're paying twice for and a collector that needs watching:
# List installed services that look like monitoring/RMM agents
Get-Service |
Where-Object { $_.DisplayName -match 'ninja|connectwise|screenconnect|pulseway|datto|syncro|n-able|zabbix|prtg' } |
Select-Object Status, DisplayName, Name |
Sort-Object DisplayName
5. Compute your real per-endpoint cost. Total every per-device and per-agent fee across all vendors and divide by endpoints under management. If you're above roughly $10 per endpoint per month across tools, you have consolidation headroom — and after the Pi price hike, count your on-site appliance spend in the same calculation.
6. Register your probes as monitored devices in AlertMonitor. Set disk and temperature thresholds, enable automated remediation for hung services, and confirm per-client alert routing so the right technician hears about a degrading card — days before it takes the client's visibility down with it.
The Bottom Line
Hardware prices will do what hardware prices do. What you control is how many tools, agents, and appliances your operation needs — and how much of your technicians' day gets burned switching between systems instead of fixing things. One multi-tenant platform cuts the license bill and the on-site hardware footprint at the same time, and it makes sure the probe watching your client's network is, itself, being watched.
