Hi Troy, 

Thanks for the tip with rrdmerge, I am looking into it. For the time being 
though, we are working with the timestamps and measurements in .log and .old 
files. It's structure seems easy enough to understand, but MRTG's behavior with 
them isn't. 

Thanks again,

With RRD files there is an rrdmerge script that will import the old data into 
the new files: 




I can't find the original download I used but it looks like this one is the 
same.

The only consideration required is that the architectures of the old machine 
and new machine must be the same (i.e. x86_64). 





Otherwise you need to export to an XML file first. This KB article explains how 
to do an export/import

Good luck.

Subject: [mrtg] Graph history being overwritten 
Hi, 

I find myself needing to restore some graphs after a server died. MRTG is 
working on a new server without issue, except for the fact it overwrites all 
files placed on it. 

When I copy in the .old and .log files for a target and initiate MRTG it always 
replaces the entirety of the two files with zeros and the graph history is 
gone. In some cases, we have graph history going back 2 years or more. 

What is the best way to restore these old files? Additionally, what is the best 
way to merge old data, or two graphs into one? 


Sincerely,
