SNMP versions
MayaUPS supports SNMP v1, v2c and v3 USM. SNMPv3 adds authentication and encrypted traffic, and MayaUPS will not poll an SNMPv3 device until the required credentials are in place.
EXPLAINER
How UPS SNMP monitoring works.
UPS SNMP monitoring reads the network-management card sitting in your UPS. The card exposes status, measurements and alarms through standard and vendor MIBs; the monitoring software turns that raw feed into states you can act on.
Credentials
Community strings and SNMPv3 USM credentials are stored encrypted and reused as named profiles, so nobody retypes secrets into individual device records. Each device still gets its own connection test before you trust the numbers.
Discovery
You start discovery yourself; it never runs on its own. It reads only, stays inside the one /24 you picked, and uses sysObjectID to match a vendor profile when one exists, with RFC-1628 as the standards baseline for devices that expose the standard MIB.
From raw data to readable states
A poll returns status, charge, runtime remaining, load, input and output voltage, temperature and alarm data. MayaUPS turns those signals into On battery, Replace battery, Overtemperature, runtime trends and site summaries instead of raw object identifiers.
Manufacturer-specific information
The standard MIB does not cover every reading. Where a manufacturer exposes more, a MayaUPS profile gives you more detailed alarm descriptions. Support varies by UPS model, network card and firmware.
How the data is used
The same SNMP data feeds the fleet view, history charts, grouped email alerts, battery forecasts and CSV reports. It can also trigger a shutdown policy, once that policy has passed a test that switches nothing off.
