NAME

snmp-ups - Multi-MIB Driver for SNMP UPS equipment

NOTE

This man page only documents the hardware-specific features of the snmp-ups driver. For information about the core driver, see nutupsdrv(8).

SUPPORTED HARDWARE

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, ie MGE UPS SYSTEMS, Liebert, perhaps others (default)

mge:

MGE UPS SYSTEMS and MGE Office Protection Systems devices with SNMP cards (ref 66062, 66045, 66074 and 66244)

apcc:

APC AP9606 APC Web/SNMP management card, perhaps others

netvision:

Socomec Sicon UPS with Netvision Web/SNMP management card/external box

pw:

Powerware devices with ConnectUPS SNMP cards

aphel_genesisII:

Eaton Powerware ePDU Monitored

aphel_revelation:

Eaton Powerware ePDU Managed

raritan:

Various Raritan PDUs

baytech:

Various BayTech PDUs

cpqpower:

HP/Compaq AF401A management card, perhaps others

EXTRA ARGUMENTS

This driver supports the following optional settings in the ups.conf(5):

mibs=name

Set MIB compliance (default=auto, allowed entries: refer to the above SUPPORTED HARDWARE). With auto the driver will try a select set of objets until it finds one that the device responds to.

community=name

Set community name (default = public). Note that you require a RW community name to perform UPS settings (as for a powerdown).

snmp_version=version

Set SNMP version (default = v1, the other allowed value is v2c)

pollfreq=value

Set polling frequency in seconds, to reduce network flow (default=30)

notransferoids

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.

REQUIREMENTS

You will need to install the Net-SNMP package from http://www.net-snmp.org/ before building this driver.

LIMITATION

Shutdown

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.

INSTALLATION

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.

IMPLEMENTATION

The hostname of the UPS is specified with the "port" value in ups.conf, i.e.:

         [snmp]
                 driver = snmp-ups
                 port = snmp-ups.example.com
                 community = public
                 snmp_version = v1
                 mibs = ietf
                 pollfreq = 15
