<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: SNMP APC Hardware Sensor

The SNMP APC Hardware sensor monitors performance counters on an APC UPS device via the Simple Network Management Protocol (SNMP).

i_round_blueThe SNMP APC Hardware sensor does not appear as a running sensor, instead it is created as an SNMP Custom Advanced sensor.

Performance impact

  • This sensor has a very low performance impact.

Knowledge Base

Add Sensor

APC UPS Specific




Select the performance counters that you want to monitor. PRTG creates one SNMP Custom Advanced sensor with all performance counters of each category that you select.

Basic Sensor Settings

Basic Sensor Settings

The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:

  • apcups

TheSe name of the interface (performance counter) that this sensor monitors.

Unit String

Define the unit of the numeric data that this sensor monitors at the OID. Enter a string.


If you want to multiply the received data with a certain value, enter the quotient. Enter an integer.


If you want to divide the received data by a certain value, enter the divisor. Enter an integer.

If Value Changes

Define what the sensor does when its value changes:

  • Ignore (default): Do nothing.
  • Trigger 'change' notification: Send an internal message that indicates a change.
    i_round_blueIn combination with a change trigger, you can use this to trigger a notification if a change occurs.

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel below the sensor's name. The available options depend on what channels are available for this sensor.

i_round_blueYou can set a different primary channel later by clicking b_channel_primary below a channel gauge on the sensor's Overview tab.

Graph Type

Define how this sensor shows different channels:

  • Show channels independently (default): Show a graph for each channel.
  • Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic.
    i_round_redYou cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).

Stack Unit

This setting is only visible if you select Stack channels on top of each other above.

Select a unit from the list. PRTG stacks all channels with this unit on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so.

Inherited Settings

By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click b_inherited_enabled under the corresponding setting name to disable the inheritance and to display its options.

i_square_cyanFor more information, see section Inheritance of Settings.

Channel List

i_round_blueWhich channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.




In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status

[Performance Counter]

The performance counters on an APC UPS device

  • Actual voltage of battery
  • Capacity of battery
  • Input and output frequency
  • Input and output voltage
  • Output load
  • Remaining runtime of battery
  • Temperature of battery
