SLOB 2 — A Significant Update. Links Are Here.

BLOG UPDATE: 2014.05.15:  The following link supersedes all other references to SLOB kit and patches. This will always be the up to date locale:  http://kevinclosson.wordpress.com/slob/

BLOG UPDATE 2013.12.26:   Quick link to download the kit

BLOG UPDATE 2012.05.05: Updated the tar archive distribution file with some bug fixes.  Simply preserve your slob.conf file and extract this tar archive over your prior SLOB install directory.

BLOG UPDATE 2012.05.04: The PDF README will no longer be bundled in with the tar archive. The README can be found here:  SLOB2 README.

BLOG UPDATE 2012.05.03: First time visitors should see the introductory page for SLOB.

About SLOB 2
I’ve already socialized the SLOB 2 update via twitter and a lot of friends have had early access to the kit. So, this is just a very brief blog entry to point to SLOB 2.

I’ve written a form of a release note that will be sufficient for current SLOB users to move forward rapidly with new SLOB 2 features. The note can be found here: SLOB 2 README or here.

Download The SLOB2 Kit
To download the software you can access the tar archive on EMC Syncplicity. Click SLOB 2 Tar Archive.

After downloading you should verify the md5sum:

    Not sure if I’m liking the popularity of SLOB….Popularity + Oracle normally equals acquisition….I can see the future now:

    Hey Kevin,

    The syncplicity links for both the TAR archive and the README are both broken. Can you point me to some valid links?

    Hi Kevin,

    How do I run SLOB2 for a specified amount of time (say a few hours) for a specified update percentage (say 20%)? I have tried setting 3600 for “RUN_TIME” and 30 for UPDATE_PCT. The run completes in about 1800 seconds instead of specified 3600 seconds. If I kick off a subsequent run keeping RUN_TIME and UPDATE_PCT setting the same in slob.conf file, the test runs randomly end within a few seconds (sometimes 5 seconds, sometimes 8 etc.).

    Thank you.
    – Saad

    Hi Kevin,

    Thanks for a very useful IO testing tool.

    I tested SLOB2 and somehow the values of “bytes per second” were not extracted correctly by the script awr_info.sh – i think the problem is with the chomp command.

    In my server (el6uek.x86_64) the command ‘chomp’ does not seem to work, so ‘bytes per second’ values are zero.

    Example:

    function get_read_mbs() {
    local f=$1

    grep ‘^physical read total bytes’ $f | head -1 | chomp | awk ‘{
    printf(“%6.0lf\n”, ( $2 / 2 ^ 20) )
    }’
    }

    I changed it to:

    grep ‘^physical write total bytes’ $f | head -1 | awk ‘{print $6}’ | awk ‘{ printf(“%6.0lf\n”,$1) }’

    May be you can provide a fix for that in the next release.

    Br,

    Pascal
