GUIDE
How SNMP UPS monitoring works.
Most UPS on a network carry a management card that answers SNMP. MayaUPS polls those cards, reads their manufacturer MIBs and listens for their traps.
The network management card
The card in the UPS slot, such as an APC NMC, Eaton Network-M3 or Vertiv RDU120, has its own address on the network and answers SNMP requests.
SNMP v1, v2c and v3
MayaUPS speaks all three versions. SNMPv3 adds user authentication and encryption, and is the version to use wherever the card supports it.
Standard and manufacturer MIBs
RFC 1628 defines the readings every UPS shares. Manufacturer MIBs add the rest: battery replacement dates, self-test results, per-phase values and commands. MayaUPS applies the right profile for each card automatically.
Polling and traps
MayaUPS polls every card every 30 seconds by default. When a card sends a trap, MayaUPS reads it again at once, so a power failure appears within seconds.
Adding cards
Scan a network range, import a list or add a card by address. Set SNMPv3 credentials once and reuse them across the fleet.
