I can't pinpoint exactly when it happened but I just noticed this after I updated to the latest subscriber version.

I use APC PDUs which allows per outlet SNMP monitoring. Graphing of each outlet was working previously but it is no longer there.

The device information is correct:

APC Web/SNMP Management Card (MB:v3.8.6 PF:v5.1.4 PN:apc_hw05_aos_514.bin AF1:v5.1.2 AN1:apc_hw05_rpdu2g_512.bin MN:AP8681 HR:02 SN: ZA1248014109 MD:11/23/2012)

RRDs of each outlet still exist in the RRD directory:

sensor-power-apc-rPDU2OutletMeteredStatusPower.6.rrd

sensor-power-apc-rPDU2OutletMeteredStatusPower.7.rrd

sensor-power-apc-rPDU2OutletMeteredStatusPower.8.rrd

sensor-power-apc-rPDU2OutletMeteredStatusPower.9.rrd

But none of the graphs are present

Voltage, Current, and Power graphs for each phase are still properly being graphed.

Any help?
