    Hello Brenden,

    Please note, that rrdcollect is not a tool for gathering memory information.
    It just reads data from any file (especially from /proc) given in
    configuration and put it into rrd file.

    You have mentioned two problems in your bugreport.

    1. /proc has been changed between 2.4 and 2.6 kernel series and given
    configuration file works only with 2.4 - well, there is no hardcoded
    value, you can change your configuration file for your own.
    I agree that could be annoyable, but there is nothing which cannot be
    fixed by modification in configuration file. Besides, I cannot prepare
    2.6 ready configuration because all 2.4 users would blame me.
    Of course, if you (or anyone) provide a sollution which works with 2.6,
    I would be happy to include it into package as an example. Of course
    it requires changes in rrd file, but I cannot do anything with this
    issue.

    2. rrdcollect has not math support - this is a feature request which should
    be directed to upstream. I submitted it to upstream BTS. If you have an
    account on SourceForge you can monitor a status of this bug by entering
    at: http://sourceforge.net/tracker/index.php?func=detail&aid=1013137&group_id=61278&atid=496702
    and clicking [Monitor] button. Additionaly I changed a qualification
    of your bugreport.


    Cheers
    Artur

    Package: rrdcollect
    Version: 0.2.1-5
    Severity: important

    The rrd package ships with tools to gather memory information, however it relies on Mem: and Swap: lines at the start of /proc/meminfo, which 2.6 does not provide

    example:

    2.4:
    # cat /proc/meminfo
    total: used: free: shared: buffers: cached:
    Mem: 4020187136 4006629376 13557760 0 118153216 3517956096
    Swap: 526409728 129978368 396431360
    MemTotal: 3925964 kB
    ...

    2.6:
    # cat /proc/meminfo
    MemTotal: 3925964 kB
    ...

    And thus cannot gather memory information. Some things are printed in the list below, however many are not - memory used, for example. While that is easy to mathematically compute, the program offers no calculation support (that i can find).
