Correctly value is 1.1A As you said yourself in UPS-MIB this value collected as "0.1 RMS Amp", that why snmp value multiplied by scale 0.1. (Just snmp values not support float type of values, this is why used increased values as an integer.)

Great progress. Data now appears in RRD, just it’s off by 10 X. Plots show 1.1, correct answer is 11.0 Amps.

When I look at the device with iReasoning MIB browser, using the UPS-MIB supplied by TrippLite, or the UPS-MIB from Observium, it says: integer: 11 See attached.

Seems most of the MIB files mention units of “0.1 RMS Amp”. Not sure what that does.

Any way to resolve this?

upsOutputCurrent OBJECT-TYPE

SYNTAX     NonNegativeInteger

UNITS      "0.1 RMS Amp"

MAX-ACCESS read-only

STATUS     current

DESCRIPTION

        "The present output current."

I see that Current output already discovered (with value 1.1):

Discover sensor: current, pdu72, .1.3.6.1.2.1.33.1.4.4.1.3.1, upsOutputEntry.1, ups-mib, Output, SCALE: 0.1, LIMITS: (, , , ), CURRENT: 1.1

But I fix (clean) some incorrectly discovered sensors in r7105.

Hi,

observium already have mostly support for UPS-MIB including upsOutputCurrent.

Seems as something wrong in snmpwalk output.

Send me debug output for:

./discovery.php -d -m sensors -h <this_device>

Hi Adam,

Still have a problem with a fresh Professional install of “current” observium/trunk.

Situation: For a Tripplite PDUMNH20 (power strip) we want to display total current. This will help us manage power consumption in our remote rack at the colo site, where we pay directly for amps.

Latest “current” Observium page generated for PDUMNH20 attempts to display a “Current” plot in the upper right. Unfortunately all values are “0” with units of “–nan”.

TrippLite Support tells me we want this data item from the UPS-MIB.

Name: upsOutputCurrent.1

OID: .1.3.6.1.2.1.33.1.4.4.1.3.1

Data : 4

Descroption: The present output current.

Please can you plot that one? What OID are you trying to plot?

What is cost of fix? Happy to go that route.

Ralph

Hi Ralph,

Its possible this is already fixed in the current subscription edition.

If not, you have two options (both of which require having a subscription!):

Hope we fix it once you confirm its not fixed in subscription. Pay someone for a couple of hours work to fix it.

The choice between the two is usually based on how much you want the fix :)

I vaguely recall some triplite stuff changing in the recent past, so chances are it's fixed already.

I don't have any of those devices though, so can't say for certain with looking into it a little further.

Adam.

Hi. New to this list, so please excuse if I break etiquette.

For couple years we happily used Observium to monitor and track current through our Tripplite PDUMNH20. Thanks to you all for Observium.

Life was OK, but the integrated Tripplite SNMPWEBCARDs had problems from time to time. Tripplite rolled out new firmware (currently 12.06.0065) and that issue was resolved. (SNMPWEBCARD is a component used in many of their products.) Unfortunately, now current plots as a flat line at 0. I’ve worked with Tripplite support to verify some data is present with snmpwalk. But probably not where Observium expects to find it. My guess is the firmware change switched to a new mib. I’ve tried to delete devices, update Observium and recreate… no luck.

Tripplite currently provides these two MIBs

http://www.tripplite.com/shared/software/Firmware/UPS-MIB-Definitions.txt

http://www.tripplite.com/shared/software/Firmware/Tripp-Lite-MIB-Definitions...

Would be happy to switch to Professional, buy support, whatever is needed to restore ability to plot Current over time from Tripplite PDUMNH20.

Any good advice?
