Yes, all 4.* versions should be compatible to one another. In some occasions, the server (i.e. the machine *receiving*) must be *at least* the version of the client (i.e. the sender), though, if you want to use new features on the client. There were some bugs in early versions of the network plugin regarding the transmission of double values, but (a) they should be fixed in 4.3 (iirc) and (b) neither the CPU nor the Disk plugins send floating point values. > 2. is 64bit pre-built ubuntu package compatible (again over the wire) > with the 32bit pre-built ubuntu package? Yes. That is, the Ubuntu people would have to make some deliberate attempt to get those versions incompatible and I very much doubt that. > 3. How is possible some plugins (MySQL) to be working just fine, while > others (CPU, DISK) to be completely wrong? Good question. The key to solving this one is liekly to understand the pattern behind the files working and the ones that don't. Do, for example, all the working files include GAUGE values while all the "broken" files include COUNTER values? For this sort of problem, having some PCAP file with captured network traffic available is usually a great help. Could you maybe try the following to capture some collectd packets?: tcpdump -w collectd.pcap -s 1600 port 25826 > 4. Any idea how to solve this without having to recompile from source > the collectd on all servers? Sorry, but I have to understand what the problem *is* before I can say anything about that. In theory, what you describe *should* work.. Regards, -octo -- Florian octo Forster Hacker in training GnuPG: 0x91523C3D http://verplant.org/
