PowerWalker NMC card misidentified as Eaton

Attached latest vendor MIB

They have not updated the changelog in MIB header, but they fixed incorrectly labeled bypass power sensor:

493c493

< 		DESCRIPTION		"The measured input real power in watts."

---

> 		DESCRIPTION		"The measured bypass input real power in watts." 

Attached discovery and poller debug logs

Not really related to this issue, but:

Just noticed that the NMC Card vendor PowerWalker has made minor description/documentation revision to the latest EPPC UPS MIB.

Change is one-liner so EPPC MIB shipped with Observium is mostly ok but bypass voltages are mislabeled as input/output voltages.

I can open separate issue for this minor MIB update if required.

Already did rediscovery when vendor and sensor value issues occurred (did it again just now to be sure). Running r12458 right now.

All of the sensors provided by the UPS are correctly discovered and polled, but the polling fails to log/graph the UPS output voltage (@ .1.3.6.1.4.1.935.10.1.1.2.18.1.3)

Meanwhile output voltage continues to be reported by the SNMP correctly:

# snmpwalk -c public -v2c <redacted fqdn for the UPS> .1.3.6.1.4.1.935.10.1.1.2.18.1.3

iso.3.6.1.4.1.935.10.1.1.2.18.1.3.1 = INTEGER: 2297 

I can provide you SNMP dumps, debug output logs etc. and test code changes if required.

Please make discovery debug as Bot written:

./discovery.php -d -h <device>

It's should be correctly detect sensors (after rediscovery)..
And vendor really not possible detect correctly, while same card can used on both UPSes (Eaton and PowerWalker)

Attached snmpwalk output (using instructed snmpwalk parameters) as powerwalker-nmc.snmpwalk

This dump is from Powerwalker NMC Card (https://powerwalker.com/product/10120517/)  attached to PowerWalker VFI 10000 TCP 3/1 BI (https://powerwalker.com/product/10120161/)

Please make and attach additional information about the device:

• full snmp dump from device:

  snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -ObentxU <hostname> .1 > myagent.snmpwalk

  snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalk

  If device not support SNMP version 2c, replace -v2c with -v1.

• If you have problems with discovery or poller processes, please do and attach these debugs:

  ./discovery.php -d -h <device>

  ./poller.php -d -h <device>

• additionally attach device and/or vendor specific MIB files
