Measures reported by UpsOnBatteryTest

This test reports the input line state of the APC UPS 3000 that is being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Ups_input_state Indicates the input line state of the UPS.   This measure reports the following states while indicating the input line state of the UPS.
  • No Transfer
  • Highline Voltage
  • BrownOut
  • BlackOut
  • Small Momentary Sag
  • Deep Momentary Sag
  • Small Momentary Spike
  • Large Momentary Spike
  • SelfTest
  • Rate Of Voltage Change
The numeric values that correspond to the above-mentioned states are as follows:

Numeric Value State Description
1 No Transfer Indicates that the UPS battery is not transferred to power i.e., the UPS is still utilizing the battery power.
2 Highline Voltage Indicates that the transfer to battery power is caused by a voltage greater than the high transfer voltage.
3 BrownOut A brownout is when the line voltage is severely reduced for a few minutes up to a few days.

This state is shown if the duration of the outage is greater than five seconds and the line voltage is between 40% of the rated output voltage and the low transfer voltage.
4 BlackOut A blackout is the complete absence of AC power.

This state is shown if the duration of the outage is greater than five seconds and the line voltage is between 40% of the rated output voltage and ground.
5 Small Momentary Sag This state is shown if the duration of the outage is less than five seconds and the line voltage is between 40% of the rated output voltage and the low transfer voltage.
6 Deep Momentary Sag This state is shown if the duration of the outage is less than five seconds and the line voltage is between 40% of the rated output voltage and ground.
7 Small Momentary Spike This state is shown if the line failure is caused by a rate of change of input voltage less than ten volts per cycle.
8 Large Momentary Spike This state is shown if the line failure is caused by a rate of change of input voltage greater than ten volts per cycle.
9 SelfTest This state is shown if the UPS was commanded to do a self test.
10 Rate Of Voltage Change This state is shown if the failure is due to the line voltage.

Note:

By default, this measure reports the above-mentioned states while indicating the input line state of the UPS. However, the graph of this measure will be represented using the corresponding numeric equivalents of the states as mentioned in the table above.
