Custom alerts and data visualization let you quickly identify and prevent issues with servers that have become unresponsive or are experiencing hardware malfunctions.
Paessler PRTG monitors accesses the IPMI interface to provide you with a constant overview of the hardware of all physical servers in your network.
Fully functional server hardware is a prerequisite for an error-free network. After all, servers are the backbone of your IT infrastructure. Of course, the applications and services on your servers will only work well if the servers themselves are running properly.
PRTG keeps a constant eye on server health and performance and acts as your early warning system for potential hardware failures to keep your business running smoothly.
IPMI usually works even when the host is turned off, which makes IPMI monitoring is a valuable tool for diagnosing hardware problems remotely without needing physical access.
PRTG comes with a handy alarm function that immediately notifies you of errors and disruptions based on individual warning and error thresholds so you can troubleshoot problems at once – even before your end users notice.
PRTG provides easy-to-read dashboards with live and historical data on server performance and availability. A quick glance is all it takes to see if everything is OK.
You can also generate detailed long-term statistics and configure automated reports that include exactly the level of information your stakeholders need for informed decision making and resource capacity planning.
Diagnose network issues by continuously tracking and managing the health and performance of IPMI devices and components remotely and in your LAN. Show CPU usage, memory, temperature, power supply, fan speed, bandwidth utilization, traffic by IP address and protocol, and other key metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot issues with remote servers and your entire network.

IPMI (Intelligent Platform Management Interface) is a standardized protocol used to manage and monitor the hardware of a server or a computer system independently of the operating system or even when the system is powered off. Developed by Intel, Dell, Hewlett Packard, and NEC in the late 1990s, IPMI is designed for remote management of servers, providing administrators with a way to monitor, troubleshoot, and perform system maintenance, especially in data centers.
IPMI is widely used but is gradually being supplemented or replaced by more secure and modern protocols such as Redfish, which offers similar functionalities with improved security and more flexible features.
Redfish is a modern, RESTful (Representational State Transfer) interface designed for managing and interacting with servers, storage, and networking hardware in data centers. It was developed by the Distributed Management Task Force (DMTF) as a replacement for the older, more complex IPMI protocol.
Redfish is widely seen as the future of hardware management in data centers, offering a more secure, flexible, and scalable alternative to IPMI:
IPMI monitoring refers to the use of the Intelligent Platform Management Interface (IPMI) protocol to track and manage the health and performance of a server's hardware components. By leveraging IPMI's out-of-band management capabilities, administrators can monitor key hardware metrics such as temperature, fan speed, voltage, power consumption, and more, even when the server's operating system is down or the machine is powered off.
With the System Event Log (SEL) functionality, IPMI can log critical hardware events such as component failures, power state changes, thermal events (overheating), and more. These logs help administrators understand when hardware issues occurred and provide information for troubleshooting.
Of course it does. The network monitoring tool natively supports common IT protocols such as SNMP, WMI and Windows performance counters for Microsoft Windows environments, SSH for Linux environments, SSL, FTP, HTTP and HTTPS, packet sniffing, or flow (NetFlow, jFlow, sFlow, IPFIX). For data centers and industrial IT/OT monitoring, it also supports technologies such as OPC UA, MQTT, and Modbus.
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.
Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
Paessler PRTG is used by companies of all sizes. Sysadmins love PRTG because it makes their job a whole lot easier.
Bandwidth, servers, virtual environments, websites, VoIP services – PRTG keeps an eye on your entire network.
