[mrtg] bytes v/s bits

1) If you are going to use a global statement (anything with [_] in it), it should be before all Targets.
2) If you want to try and change Options for each Target, try putting the Options[mytools_my-router-1_3.interfacegigabitethernet0-0]: bits,growright, before the Target as well.

Subject: [mrtg] bytes v/s bits

Hello List,

We are facing an issue with MRTG where the Bandwidth utilization on the polled equipment is showing in bits instead of bytes.

Below is the header of mrtg.cfg file  (Options[_]:bits is set):
EnableIPv6: no
WorkDir: /rddbs/
Options[_]: bits,growright
RunAsDaemon: Yes
LogFormat: rrdtool
PathAdd: /data/rrdtool-1.2.19/bin
LibAdd: /data/rrdtool-1.2.19/lib/perl
Forks: 4

I tried to set the option under the monitored interfaces themselves but this did not help.
##### Customer: tools
## x.x.x.x - Interface 3

Target[mytools_my-router-1_3.interfacegigabitethernet0-0]: 3:public@ x.x.x.x
MaxBytes[mytools_my-router-1_3.interfacegigabitethernet0-0]: 12500000
Title[mytools_my-router-1_3.interfacegigabitethernet0-0]: Traffic Analysis for mytools x.x.x.x 3
Options[_]: bits,growright

I also found a post where setting the 64 bit counters helped but it did not work for me even though my equipment supports 64 bit counters.
Target[mytools_my-router-1_3.interfacegigabitethernet0-0]: 3:public@ x.x.x.x:::::2

Any ideas/suggestions are highly appreciated.
