[mrtg] Using cfgmaker with template and multiple targets on NT

I have a c7000 blade server enclosure with 6 3020 switches that I would like to monitor with one config file.
I thought I read somewhere that this could be done using cfgmaker with multiple targets defined so I tried this with the following definitions
perl c:\mrtg-2.16.2\bin\cfgmaker  --host-template=cisco.htp --snmp-options=:::::1 --community=mybusy --ifref=name --show-op-down --global="Workdir: c:\Progra~1\RRDtool\rrd_data"  --global="PathAdd: c:\Progra~1\RRDtool"  --global="LogFormat: rrdtool" --global="routers.cgi*Options[_]: scaled" --global="Options[_]: bits,growright" --output="c:\mrtg_setup\configs\BLSWR5E3A1.cfg" BLSWR5E3A1 BLSWR5E3B2 BLSWR5e3A5 BLSWR5E3b6

This runs and builds a cfg file BLSWR5E3A1.cfg but it shows up in mrtg (using rrdtools and routers2.cgi) as BLSWR5E3b6 under devices.
All information is displayed and monitored but why is the device name wrong and how can I correct it.

You would need to delete and re-create the Monthly RRAs (both AVG and MAX) in the RRD file to have 1cdp=12dp rather than 24dp.  You'd also need to double the number of lines in each RRA so that the graph could be made.  This would probably require you to completely delete the RRD file and manually re-create it from the command line before running MRTG (else MRTG would recreate it with the default parameters).

This is not simple but if you read the RRDTool documentation you should be able to work out how to do it.

I was just wondering how you change the sampling rate of the monthly graphs from 2 hours to 1 hour?

kind regards
