Unified Aruba Monitoring

Keep tabs on Aruba switches, access points, and gateways. Bandwidth usage, hardware health, real-time network performance: all of it in one place.

How do you get full visibility into Aruba switches, access points, and gateways in one place?

PRTG uses SNMP, sFlow, and ICMP to pull data from your Aruba infrastructure. From a single dashboard you track device health, bandwidth usage, interface errors, CPU load and connectivity across switches, wireless access points and controllers. PRTG's observability approach covers real-time performance metrics and historical trends, which makes troubleshooting faster and gives you the data to actually understand what happened, not just react to it. And because PRTG runs on industry-standard protocols it fits into your multi-vendor environment without proprietary agents on the Aruba side.

Supported device types include Aruba CX switches, Aruba Instant APs (IAP), Mobility Controllers and Mobility Gateways, plus both ArubaOS-CX and ArubaOS-Switch. PRTG polls them via SNMP, sFlow, NetFlow, or ICMP depending on what the device supports.

Full Visibility Into Your Aruba Network

Pinpoint Which Devices and Applications Are Consuming Bandwidth

Tracking bandwidth consumption across every port and switch used to mean hours of packet captures and log analysis. PRTG's sFlow and SNMP sensors give you that picture in minutes: which IP addresses, connections, and protocols are driving traffic on every port, across every switch. Clear graphs and real-time data mean you spend time acting on the information, not gathering it.

Top Talkers analysis shows which IP addresses are consuming the most bandwidth at any given moment
Top Connections reveals device-to-device communication patterns across your network
Top Protocols breaks down which applications are hogging bandwidth. Often the culprit is something you wouldn't expect
Per-port SNMP traffic monitoring tracks utilization on every switch interface
Historical graphs let you optimize capacity planning before a link actually saturates

Monitor Switch and AP Hardware Health Proactively

Staying ahead of hardware issues on switches and access points means watching the right metrics continuously. PRTG monitors CPU load, memory utilization, temperature, fan status, and power supply health via SNMP, sending notifications when performance metrics cross threshold levels. Your team gets the information early enough to act before users are affected.

CPU and memory monitoring catches resource exhaustion and memory leaks before they cause problems
Temperature and fan status tracking. Overheating is one of the more preventable failure causes
Power supply health alerts warn of PSU issues before they take a switch offline
Threshold-based notifications via email, SMS, or push when metrics exceed safe levels
Historical trend data spots degradation patterns. Useful when something degrades slowly rather than failing outright

PRODUCT OVERVIEW

Port-Level Visibility Across All Your Switches

Port-level error data is some of the most actionable information you can have for network troubleshooting. PRTG's SNMP Traffic sensors track per-port errors, discards, collisions, and interface status changes continuously. CRC errors show up too when the device makes them available, which is usually enough to identify a bad cable or failing transceiver before users ever notice.

Input/output errors and packet discards tracked per port
Error patterns help identify bad cables and failing transceivers. CRC errors are particularly useful here when the device exposes them
Collision monitoring catches duplex mismatches and network loops
Port flapping alerts when an interface goes up/down repeatedly. Often the first sign of a dying transceiver
Per-port visibility across all switches simultaneously, not just the ones you think to check

How PRTG Monitors Aruba Networks

PRTG uses industry-standard protocols: SNMP, sFlow, NetFlow, and ICMP. No proprietary connectors, no Aruba-specific agents. Here's what each method actually monitors and what visibility it gives IT teams.

SNMP Device Monitoring

PRTG's SNMP sensors query Aruba devices to collect hardware health data: CPU load, memory utilization, temperature, fan status and power supply status. On the interface side you get bandwidth, utilization, errors, discards, collisions and link status. Any Aruba device that exposes standard MIBs works here, including CX switches, Instant APs (IAP), Mobility Controllers and gateways. Authentication is standard SNMP community strings or SNMPv3 credentials, nothing beyond that.

sFlow Traffic Analysis

PRTG's sFlow and NetFlow sensors analyze traffic flows to show Top Talkers (which IP addresses consume the most bandwidth), Top Connections (who's talking to whom) and Top Protocols (which applications and services are eating bandwidth). This header-based analysis gives you real insight into bandwidth usage patterns without the overhead of full packet capture. For high-traffic environments that distinction matters, because full captures at scale get expensive fast. Also useful for capacity planning once you actually know what's driving utilization.

Packet Sniffer Monitoring

PRTG's built-in Packet Sniffer analyzes packet headers in real-time as they pass through local network adapters, categorizing traffic by protocol type: FTP, Mail, Web, Infrastructure, NetBIOS, Remote Control and others. That gives you observability into application usage patterns that flow-based analysis won't always surface. Worth noting: the Packet Sniffer carries a higher performance impact than SNMP or flow sensors. Use it for targeted monitoring only, not broad deployment.

Ping and ICMP

PRTG's Ping sensors cover availability, response time and basic connectivity via ICMP. When a switch, access point, controller or gateway stops responding you know immediately. Combined with historical uptime tracking and threshold-based alerting, that data also feeds into SLA reporting and availability trend analysis. Not the deepest monitoring method, but for reachability it's the most reliable signal you have.

“From a server perspective, we're monitoring all of the key components of our service such as CPU usage, RAM disk space, the Windows services that it's running, and network connectivity of that server. In terms of networks, we’re monitoring all of our switches, firewalls, and access points. It’s really useful to be able to easily pull performance metrics from the PRTG dashboard.”

Riverford Organic Farmers

“The tool has given us greater control over all types of devices connected to the network (switches, IP telephony, security cameras, IoT, WiFi) that previously remained opaque when dealing with service incidents. This has improved our ability to diagnose and resolve problems, which has translated into greater efficiency and a better user experience in both internal and public services.”

Jordi Tolosà Bel, New Technologies Technician

Vinaroz City Council

“Our objective was to be able to monitor the health of our most critical servers containing data and applications, but also the flows and bandwidth between headquarters, our 50 servers in the cloud and the 15 servers at our production sites. For us, it is essential to have a proactive approach to understand where the weaknesses of the IT system are to be able to improve them.”

Aruba Monitoring: Frequently Asked Questions

Can PRTG monitor Aruba switches and wireless access points without installing agents?

Yes. PRTG uses agentless network monitoring via SNMP, sFlow, NetFlow, and ICMP. As long as SNMP is enabled on your Aruba devices (standard practice for network management), PRTG can monitor hardware health, interface metrics, bandwidth usage, and connectivity without installing any software on the switches, controllers, or access points.

Does PRTG work with both Aruba CX (AOS-CX) and older ArubaOS-Switch devices?

Yes. PRTG monitors any Aruba networking device that supports standard SNMP, sFlow, NetFlow, or ICMP protocols. This includes Aruba CX switches running AOS-CX, legacy ProCurve/ArubaOS-Switch devices, Aruba Instant APs (IAP), Mobility Controllers, and Mobility Gateways. PRTG's generic SNMP sensors and device templates work across all Aruba product lines.

What's the difference between sFlow and SNMP for monitoring bandwidth usage?

SNMP monitors per-port bandwidth utilization (total traffic in/out on each interface). sFlow analyzes traffic flows to show which specific IP addresses, connections, and protocols are consuming that bandwidth (Top Talkers, Top Connections, Top Protocols). Use SNMP to see how much traffic; use sFlow to see who and what is generating it. Both methods work together for complete bandwidth visibility.

Can PRTG monitor wireless network performance and Wi-Fi client connections like Aruba Central does?

PRTG monitors Aruba wireless access points as infrastructure devices—tracking availability, uptime, CPU, memory, and interface traffic via SNMP and Ping sensors. For detailed Wi-Fi client metrics (per-client signal strength, roaming behavior, channel utilization per AP), Aruba Central and similar wireless-specific management platforms provide deeper radio-level observability. PRTG focuses on infrastructure health and network performance monitoring across your entire multi-vendor environment.

How does PRTG handle monitoring Aruba devices in distributed network infrastructure with remote sites?

PRTG's Remote Probe architecture allows you to deploy lightweight probes at remote sites (branch offices, remote campuses, data center locations) that monitor local Aruba devices and report back to the PRTG core server. This network management approach reduces WAN traffic, provides local monitoring even if WAN links fail, and gives you centralized visibility across all locations from one dashboard. You can also use device templates and auto-discovery automation to quickly deploy standardized monitoring configurations across multiple sites on demand.
