What is inputFrequency?

The frequency of the UPS's incoming utility power, in milliHertz; a reading straying far from the expected 50,000 or 60,000 mHz points to unstable utility power feeding the UPS.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.3.9999.3.1
snmpwalk -v2c -c public <target> SNMP-UPS-MIB::inputFrequency

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.3.9999.3.1.1
snmpget -v2c -c public <target> SNMP-UPS-MIB::inputFrequency.1
