[rrd-users] MRTG - Problem importing MRTG log files into RRDTool (W2K to Linux)

Wed Jul 9 03:50:58 MEST 2003

I'm trying to convert mrtg log files into rrdtool archives and have hit a problem with the conversion.

I've copied the Windows 2000 mrtg .cfg and .log files to a new directory on my linux machine, added the "LogFormat:rrdtool" directive to the .cfg file and started MRTG.

MRTG has built the .rrd files as expected but the .rrd files are missing their "MAX 300 seconds" archives, so I don't have any 'max 5 minute data' that I can plot.
("AVERAGE 300 seconds" archives seem to be ok).

I have repeated this using the following versions of MRTG and RRDTool without success:

MRTG version 2.9.17 with RRDTool 1.0.38	(RedHat 7.3)
MRTG version 2.9.29 with RRDTool 1.0.41	(Redhat 7.3)

Below is an extract from one of the log files. It was created by MTRG version 2.8.6 running on a Windows 2000 server.

Only things I can think of are:

MRTG bug ? (but I don't really think so)
Log formats between Linux and Windows implementations of MRTG may be different ? 

Any ideas or ways around this ??

Thanks in advance,
Neil M
