mk-profile-compact

NAME

mk-profile-compact - Compact the output from mk-query-profiler.

SYNOPSIS

To view queries 2, 4 and 6 side by side:

    mk-profile-compact -q 2,4,6 profile-results.txt
 
 

To view summaries from two runs side by side:

    mk-profile-compact -m SUMMARY results-1.txt results-2.txt
 
 

DESCRIPTION

mk-profile-compact slices and aligns the output from mk-query-profiler so you can compare profile results side by side easily. It prints the first profile result intact, but each subsequent result is trimmed to be as narrow as possible, then aligned next to the first.

You can also use this to examine only some profile results. For example, if you have a set of queries to get a table into a known state, and then a query you want to profile, you can ignore the setup queries. This is typically easy to do with a command-line option like ``--queries'' 4,8,12,16,20 to view every 4th query.

If the first profile it sees is labeled QUERY X, it will only look at QUERY profiles from then on. The same holds for SUMMARY profiles. This is because there are different numbers of lines in QUERY and SUMMARY profiles. You can specify which kind of profile result you want to process. See mk-query-profiler for the full list of types.

DOWNLOADING

You can download Maatkit from Google Code at <http://code.google.com/p/maatkit/>, or you can get any of the tools easily with a command like the following:

    wget http://www.maatkit.org/get/toolname
    or
    wget http://www.maatkit.org/trunk/toolname
 
 

Where "toolname" can be replaced with the name (or fragment of a name) of any of the Maatkit tools. Once downloaded, they're ready to run; no installation is needed. The first URL gets the latest released version of the tool, and the second gets the latest trunk code from Subversion.
