Can't help on the stability, but the RRD migration is simple. However, before you do it, check if you need to. The problem has to do with big-endian, little-endian issue. This page explains it better. http://en.wikipedia.org/wiki/Endianness

Also, from the same page, we see that the PA-RISC architecture has a switchable endian feature. X86 (As used in the DL380 G5) is little-endian.

So, before we start, copy any rrd file from your old hobbit server to /tmp on the same server. Then copy the file in /tmp to /tmp on the new one. (Both files should now be, byte for byte, identical) Do an rrdtool dump on both files, and diff or checksum the output. If they are different, we need to migrate. If they are the same, you have the same endianess, and can just copy them over.

If you need to migrate, see here. http://www.hswn.dk/hobbiton/2008/08/msg00125.html

Hi all,

My current hobbit 4.2.0 server, running on HPUX 11v1 has served us well over the past almost three years, but the old rp5400 with 2x540 Mhz PARISC chips, monitoring 435 hosts across 3 continents is starting to run out of steam and its time it be replaced.

I just got two new HP DL380 G5 servers which we purchased to build out as new Xymon servers (one for prod and one for DR). I am wondering what is currently the most stable release of Xymon? I see 4.3.0-beta2 is the most recent. Would that be the best to use for new production monitors?

I am building them with RedHat AS 5 update 2. Anybody know of any Gotha's I should be aware of?

Finally, I have seen comments about people who have written scripts to transfer the data out of RRD files an old server to their new server. Since I am migrating from HPUX to RedHat, I gather that is my only option to migrate the RRD data. Anyone out there willing to share their scripts which do this migration? That would sure save me a lot of coding and testing time.

Thanks in Advance, Bruce
