[rrd-users] Re: Accessing RRDtool information across different fi le names

[William Owen]

There are really two options here.  Either:
1.  Export your data from and delete your new RRDs, update the old ones with
the new data and then rename the old ones to the new names.

--or--
2.  User routers2 to create a target that is not being polled by mrtg that
looks something like this:
Routers.cgi*Target[ipaddress_1]: <doesn't matter what goes here>

Of course you will need to fill out all of the other MRTG options such as
MaxBytes ect and make sure to propend routers.cgi* to them.

This function became available in one of the more recent versions but I use
it in v2.16beta5.

Subject: [rrd-users] Accessing RRDtool information across different file
names

Hi
We have been running MRTG, RRDtool and Routers2 for some months, using
the default cfgmaker option --ifref=nr.
This produced file names of the format ipaddress_1.rrd.
Recently we decided to have something more meaningful than interface
number: we chose --ifref=name, giving file names of the format
ipaddress_fa0_1.rrd.
The old files are still there. Have we lost the ability to view the
information contained in them?
Can old  & new files be viewed at the same time?
