Hi,
Anyone else having trouble with RB751 and snmp?
I 'm used to monitor my RB750GL’s with cacti, which works fine. Now, when monitoring RB751U-2HnD all graphs stay empty.
Debug of for example ether1 (wan):
RRDTool Command:
/usr/bin/rrdtool graph -
–imgformat=PNG
–start=-86400
–end=-300
–title=‘stn249 - Traffic - ether1-wan’
–rigid
–base=1000
–height=120
–width=500
–alt-autoscale-max
–lower-limit=0
–vertical-label=‘bits per second’
–slope-mode
–font TITLE:12:
–font AXIS:8:
–font LEGEND:10:
–font UNIT:8:

GPRINT:cdefe:LAST:“Current:%8.2lf %s”
GPRINT:cdefe:AVERAGE:“Average:%8.2lf %s”
GPRINT:cdefe:MAX:“Maximum:%8.2lf %s\n”
COMMENT:" \n"
HRULE:0#FF0000FF:“95th Percentile”
COMMENT:“(0 mbit in+out)”
RRDTool Says:
OK
I say, NOK, values stay zero 
Any hints or comfirmation that snmp works correctly in RB751-2Hnd running RouterOs 5.6? (tried 5.11, same issue)
Many thx
B.
