If your UPS devices support SNMP, PRTG will automatically detect them and create sensors to monitor their health and availability.


Fast, customized alerts

PRTG will immediately alert you to power-related events, outages, and equipment failures so you can act as quickly as possible.

Set specific warning and error thresholds so that PRTG can notify you about problems with batteries that need replacement or heavy loads where your batteries would not meet your runtime requirements.

100% uptime targeted

PRTG power supply monitoring should be part of your power backup and monitoring strategy. Monitoring and staying aware of the status of your power systems is crucial to reducing unplanned outages and helping you achieve 99.999% uptime.

Use PRTG’s historical monitoring data to analyze power capacity and resources, and report to your management on how to optimize your power supply system based on facts, not suppositions.








What power supply monitoring looks like in PRTG

Diagnose network issues by continuously monitoring the condition, health, and performance of your UPS and PDU devices. Show battery runtime, voltage, plug status, and more in real time and visualize data in graphic maps & dashboards to identify problems more easily. Gain the visibility you need to troubleshoot issues with your power supply system.


Easily find the source of the problem with our PRTG UPS monitoring solution

How PRTG monitors power supply systems

UPS monitoring with PRTG

For generic uninterruptible power supplies, PRTG can keep an eye the following parameters, depending on what the device’s manufacturer supports:

  • Battery status (normal, low, depleted)
  • Remaining runtime, time on battery
  • Input/output voltage
  • Input out-of-tolerance count (brown-out or high/low voltage events)
  • Active alarm count
  • Output source (normal, bypass, battery, [voltage] boost/reduce)
  • Self-test result (pass, warning, error, aborted, etc. if supported)

PDU monitoring with PRTG

You can monitor many aspects of the health of the PDU itself, and often the power draw of each of the plugs. You can also keep track of how much power each of your devices consumes over time.

For power distribution units, PRTG can keep an eye the following parameters, depending on what the device’s manufacturer supports:

  • Status
  • Input/output voltage
  • Input phase
  • Socket/plug status (on/off)
  • Socket/plug current

Check out APC UPS system monitoring with PRTG









APC by Schneider Electric is a common manufacturer of UPS systems. PRTG includes several options to monitor APC UPS systems.


Preconfigured PRTG sensor

The SNMP APC Hardware sensor provides the most important standard values of an APC UPS device like battery capacity, voltage, or temperature using the Simple Network Management Protocol.

Non-SNMP sensors

If the APC system does not support SNMP, you can also use the custom EXE/Script Advanced sensor to read out the most important values of the UPS using PowerShell. Find out more in our Knowledge Base article.

Advanced monitoring

For more advanced monitoring, there are several custom sensors written by PRTG users that provide additional data such as a necessary battery replacement or the reason for the last failure. Discover some of these scripts in our PRTG Sensor Hub.

Monitor UPS: FAQ


What is a UPS?

A UPS stands for “uninterruptible power supply”. It's a device that provides emergency power to a load when the input power source fails. UPS systems are commonly used to protect computers, data centers, telecommunication equipment, or other electrical equipment where an unexpected power disruption could cause data loss, damage, or downtime.

UPS units typically incorporate batteries or supercapacitors to store energy, which can be quickly deployed when the main power source fails. They also often include surge protection and voltage regulation features to ensure stable and clean power delivery to connected devices.

What is a PDU?

A PDU stands for “power distribution unit”. PDUs take power from a primary source (such as a UPS or mains power) and distribute it to multiple devices or pieces of equipment within a data center, server room, or other industrial settings. PDUs are typically mounted within equipment racks and provide electrical outlets or connections for servers, networking equipment, storage devices, and other hardware.

What is UPS monitoring?

UPS monitoring refers to the process of actively monitoring and managing uninterruptible power supply systems to ensure their proper functioning and reliability. This involves continuously monitoring various parameters and metrics related to the UPS units to detect potential issues, prevent downtime, and maintain optimal performance.

Key aspects of UPS monitoring typically include:

  • Monitoring the input power source and the UPS output to ensure that the UPS is providing consistent and clean power to connected equipment.
  • Monitoring the status and health of the UPS batteries, including their charge level, temperature, and overall condition. This is crucial because batteries degrade over time and need to be replaced periodically to maintain UPS effectiveness.
  • Tracking the power consumption and load levels on the UPS to ensure that it is not overloaded, which could lead to system instability or downtime.
  • Detecting and alerting administrators to any faults or abnormalities within the UPS system, such as component failures, overheating, or voltage fluctuations.

Why should I monitor my power supply system?

Electrical and power systems, like monitoring, are often overlooked as being an important part of the infrastructure. A backup power system at a minimum in the form of UPS, for example, is a must to keep your systems operational in the event of an outage.

Most power outages are fairly short and for critical systems, a UPS should be able to keep you going for 30 minutes or more. This would allow you to get through most outages without interruption and give you enough time to start shutting down systems when the battery charge drops to a critical level.

A UPS combined with a generator for extended outages is desirable for critical systems, though often cost extensive. Unless you are monitoring your power systems, you may still be caught off guard and have systems go offline without a graceful shutdown.

What is a sensor in PRTG?

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.
