Citeren Philip Ward <[email protected]>:
Why did you remove the three phase support? The unit seems to
correctly report the number of input- and output phases, so leaving
that in wouldn't hurt. Even though it's not tested, you already know
it works for single phase units.
I removed it because requesting a specific 3-phase variable does not
work (at least on the units I have to hand).
Most likely, because they are apparently wired for single phase operation:
.1.3.6.1.4.1.232.165.3.3.3.0 = INTEGER: 1
(upsInputNumPhases.0 = INTEGER: 1)
In most cases the above means that if you want to read the input
voltage, you don't mention the phase (or use the extension ".0"):
.1.3.6.1.4.1.232.165.3.3.4.1.2
.1.3.6.1.4.1.232.165.3.3.4.1.2.0
Compare the following:
hostadm:/etc/nut# snmpget -v 1 -c public \
ups-pf34-2 .1.3.6.1.4.1.232.165.3.3.4.1.2.1
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: CPQPOWER-MIB::upsInputVoltage.1
Yes. When a unit is wired for single phase operation, you usually
don't need (sometimes even, must not) add a phase.
hostadm:/etc/nut# snmpget -v 1 -c public \
ups-pf34-2 .1.3.6.1.4.1.232.165.3.3.4.1.2
CPQPOWER-MIB::upsInputVoltage.1 = INTEGER: 245
This is indeed what we expect.
This suggests to me that requesting the 3-phase values will cause an
error. Unless I have misunderstood how the driver grabs the values. Does
the SU_INPUT_3 flag tell the driver to ask for (for
example) .1.3.6.1.4.1.232.165.3.3.4.1.2, and then only grab the one that
it asked for?
No, this flag will tell it to only query for this variable if the
input_phases value is 3. So you'd still need to query for
.1.3.6.1.4.1.232.165.3.3.4.1.2.(1|2|3)
to read the values. Adding something like
{ "input.voltage", 0, 1.0, CPQPOWER_OID_IN_VOLTAGE ".0", "",
SU_INPUT_1, NULL },
{ "input.L1-N.voltage", 0, 1.0, CPQPOWER_OID_IN_VOLTAGE ".1", "",
SU_INPUT_3, NULL },
{ "input.L2.N.voltage", 0, 1.0, CPQPOWER_OID_IN_VOLTAGE ".2", "",
SU_INPUT_3, NULL },
{ "input.L3-N.voltage", 0, 1.0, CPQPOWER_OID_IN_VOLTAGE ".3", "",
SU_INPUT_3, NULL },
usually does the trick.
