snmp-ups - Multi-MIB Driver for SNMP UPS equipment
This man page only documents the hardware-specific features of the snmp-ups driver. For information about the core driver, see nutupsdrv(8).
The snmp-ups driver automatically detects and supports a wide range of devices by loading various MIBS: ietf:: UPS that is RFC 1628 (UPS MIB) compliant, e.g. MGE UPS SYSTEMS, Liebert, perhaps others (default)
MGE UPS SYSTEMS and MGE Office Protection Systems devices with SNMP cards (ref 66062, 66045, 66074 and 66244)
Socomec Sicon UPS with Netvision Web/SNMP management card/external box
Powerware devices with ConnectUPS SNMP cards
Eaton Powerware ePDU Monitored
Eaton Powerware ePDU Managed
Various Raritan PDUs
Various BayTech PDUs
HP/Compaq AF401A management card, perhaps others
This driver supports the following optional settings in the ups.conf(5):
Set MIB compliance (default=auto, allowed entries: refer to the above SUPPORTED HARDWARE). With "auto", the driver will try a select set of SNMP objects until it finds one that the device responds to.
Set community name (default = public). Note that you require a RW community name to change UPS settings (as for a powerdown).
Set SNMP version (default = v1, the other allowed value is v2c)
Set polling frequency in seconds, to reduce network flow (default=30)
Disable the monitoring of the low and high voltage transfer OIDs in the hardware. This will remove input.transfer.low and input.transfer.high from the list of variables. This should only be used on APCC Symmetra equipment which has strangeness in the three-phase power reporting.
Set the securityLevel used for SNMPv3 messages (default=noAuthNoPriv, allowed: authNoPriv,authPriv)
Set the securityName used for authenticated SNMPv3 messages (no default)
Set the authentication pass phrase used for authenticated SNMPv3 messages (no default)
Set the privacy pass phrase used for encrypted SNMPv3 messages (no default)
Set the authentication protocol (MD5 or SHA) used for authenticated SNMPv3 messages (default=MD5)
Set the privacy protocol (DES or AES) used for encrypted SNMPv3 messages (default=DES)
This driver does not provide a proper upsdrv_shutdown() function. There probably never will be one, since at the time this script should run (near the end of the system halt script), there will be no network capabilities anymore. Probably the only way to shutdown an SNMP UPS is by sending it a shutdown with delay command through upscmd(8) and hope for the best that the system will have finished shutting down before the power is cut.
This driver is only built if the Net-SNMP development files are present on the system. You can also force it to be built by using "configure --with-snmp=yes" before calling make.
The hostname of the UPS is specified with the "port" value in ups.conf, i.e.:
driver = snmp-ups
port = snmp-ups.example.com
community = public
snmp_version = v1
mibs = ietf
pollfreq = 15
desc = "Example SNMP v1 device"
