*nix xymon client directories size (DU change is possible?)
Hi all: after reviewing the mailist archive and read the wiki...I came with one question.. AFAIK the DIR monitoring/track will use a DU on the xymon client (*nix ones). I need to monitor/track some directories on ZFS and they are Big. I mean 880GB or more. a simple du -sh or just du takes at least 45min. Of course; doing a zfs list pool/zfs gave me the same data that a du but almost instantaneously... So my question do I can override which command is used to DIR monitoring ? Or I must go with a script that do zfs list and push that data to rrd as independent test?
To make things worst I have mixed UFS/ZFS structures, but just need to monitor/track some of them.
Thanks a lot for any input!

If you do your "zfs list pool"(?) on a UFS file system does it give an error?
If so, you could try something like: "zfs list pool <additioanl args> 2> /dev/null || du <additional args>"
Just a thought...

That's right Colin: If I do a zfs list over a non-zfs it gave error this logic could be use. But my question goes arround if I have to implent a special DIR monitoring/track feature via script or I can augment functionality of the actual DIR monitoring/track feature (implicit humble request to know how!) to acomplish this taks. I have seen scripts that monitor the zpool but not the zfs itself. And a review of the .cfg told me that command found are just for some cases. I'm using verion 4.2.3 of xymon/hobit.

In the client configuration, you can set the "DU" environment variable to the command you want to run. The Xymon client will pick up this setting and use it instead of the default "du -k".
To make things worst I have mixed UFS/ZFS structures, but just need to monitor/track some of them.
Well, if you can script some way of detecting which command to use for which structure, that script can then be used for the "DU" env. setting.
