I’ve added something like this to the DEFAULT section at the end of `hobbit-cleints.cfg`.

    DISK    /mnt IGNORE

But if I mount something on /mnt, it still shows up, alerts, etc. Does this have to be specified per-host/per-page/per-class or should it be possible to define such a thing under DEFAULT?

Related question: How can I “drop” a single filesystem that I don’t want to see historical data for?

Thanks.

For DEFAULT (which I thought had an S, no?) order is important. I think it has to be last in the file, but I do not recall. This bit me similarly a week or so ago.

As for dropping a filesystem from the history, I go looking for it in the
data/rrd directory and just remove the rrd file.

There’s no S in the examples or documentation, but that doesn’t necessarily mean it shouldn’t be there.

I knew someone would bring that up, which is why I specifically said “the DEFAULT section at the end of `hobbit-cleints.cfg`”. :)

Any other ideas?

Default is read last, whatever is above it has already been parsed and added to the config.  So, it may be that this FS is picked up explicity at some higher level.... maybe..  Have not spent any time on this in many moons.

No, there are no mentions of `/mnt` higher up in the file, but thanks.

Ah! I think I've figured it out. My apologies for the
reading-comprehension problem earlier. ;)

What I believe to be the problem is that your DISK * 90 95 entry comes
before the /mnt entry. That could be a bum guess, but I think it's the
most likely. FYI, here is my DEFAULT section:

DEFAULT
        # These are the built-in defaults.
        UP      1h
        LOAD    5.0 10.0
        DISK    %^/cdrom.* IGNORE
        DISK    %^/mnt.* IGNORE
        DISK    * 90 95
        MEMPHYS 100 101
        MEMSWAP 50 80
        MEMACT  90 97

I don't know if all of the punctuation is necessary if you're looking
specifically for one name of a filesystem, but I can tell you that mine
works (and handles /mnt/cdrom, or things like Solaris' /cdrom/cdrom0/s0,
etc.).

It sure does. That’s a good theory. I’ll test it out and let you know. Thanks.

Looks like that was it. Thanks.
