plugin:mikrotik#mikrotik

[kellogs]

Dear Cacti users,

I am using http://docs.cacti.net/plugin:mikrotik#mikrotik with cacti Version 0.8.8a.

I am running Mikrotik 5.20 using Queue Tree on my customers.

After loaded this plugins and imported the host xml file, I am unable to see any graphs for the queue tree.

I am seeing the following on the cacti.log file

09/16/2013 11:03:02 PM - SPINE: Poller[0] Host[16] ERROR: Empty result [10x.2x.2.6x]: '/usr/bin/snmpwalk 10x.2x.2.6x -Cc -v 2 -c xxx .1.3.6.1.4.1.14988.1.1.1.2.1.3 | /bin/wc -l | /bin/awk '{printf$0}''
