Added:
  ** Set random seed of sysbench to have better comparison
  ** Restart mysqld from scratch for each run and copy away
  DATA_DIR of the database for faster starts.
  ** Between each run, run sync and clear file system caches with
  echo 3 > /proc/sys/vm/drop_caches (http://linux.die.net/man/5/proc)
  ** Write out mysqld and sysbench options for reference.
Worked 8 hours and estimate 32 hours remain (original estimate unchanged).

DESCRIPTION:

Create a benchmark suite for running sysbench

* Run sysbench tests on a machine and collect numbers
* Analyze numbers
* Generate a report out of the numbers


LOW-LEVEL DESIGN:



All scripts can be found at lp:mariadb-tools/sysbench

* Run sysbench tests on a machine and collect numbers
This is implemented in run-sysbench.sh. Currently it supports:
 ** Optionally pull of latest source from Launchpad and compile
 ** Starting the server
 ** Running each sysbench test for $LOOP_COUNT times and 
 $RUN_TIME time.
 ** Number of concurrent clients is hardcoded
 ** Machine specific configuration like location of binaries and
 directories needed are in separate config files located at conf/<hostname>.inc

The main loop of run-sysbench.sh is:

start_mysqld
for SYSBENCH_TEST in $SYSBENCH_TESTS
    for THREADS in $NUM_THREADS
        while [ $k -lt $LOOP_COUNT ]
            drop schema sbtest
            create schema sbtest

            $SYSBENCH $SYSBENCH_OPTIONS prepare
            $SYSBENCH $SYSBENCH_OPTIONS run
        done
    done
done

Open items:
  ** OProfile hook
  ** iostat hook
  ** sar -u (CPU utilization) hook
  ** Crash detection
  ** Error detection
  ** Set random seed of sysbench to have better comparision
  ** Restart mysqld from scratch for each run and copy away
  DATA_DIR of the database for faster starts.
  ** Between each run, run sync and clear file system caches with
  echo 3 > /proc/sys/vm/drop_caches (http://linux.die.net/man/5/proc)
  ** Write out mysqld and sysbench options for reference.

* Analyze numbers
This is implemented in analyze-sysbench.php

Open items:
  ** Read result files from
  ${RESULT_DIR}/${TODAY}/${PRODUCT}/${SYSBENCH_TEST}/${THREADS}/results.txt
  
  ** Collect OProfile, iostat, cpu utilization, and machine info
  ** Detect errors and crashes.
  ** Generate SQL INSERT strings for presentation usage

The layout for storing the numbers is:
  CREATE TABLE sysbench_run (
    id int unsigned NOT NULL auto_increment,
    host varchar(80),               -- Hostname we ran the test on.
    run_date date,                  -- The day we ran the test.
    sysbench_version varchar(32),   -- Version of sysbench we used.
    test_name varchar(32),          -- Name of the sysbench test.
    run_time int unsigned,          -- Run time in seconds.
    runs int unsigned,              -- Number of iterations of the test.
    PRIMARY KEY (id),
    KEY (host),
    KEY (run_date
  );

  CREATE TABLE sysbench_comment (
    id int unsigned NOT NULL auto_increment,
    sysbench_run_id int unsigned NOT NULL,  -- FK pointing to sysbench_run.
    compile_info text,                      -- Compile options we used.
    machine_info text,                      -- Details about the hardware.
    sysbench_options text,                  -- The sysbench options we used.
    PRIMARY KEY (id),
    KEY (sysbench_run_id)
  );

  CREATE TABLE sysbench_result (
    id int unsigned NOT NULL auto_increment,
    sysbench_run_id int unsigned NOT NULL,  -- FK pointing to sysbench_run.
    concurrency int unsigned,               -- Concurrency level we used.
    result decimal(7,2),                    -- The actual result.
    io varchar(80),                         -- The IO from iostat.
    cpu varchar(80),                        -- CPU utilization.
    profile text,                           -- Profiling information.
    error text,                             -- Error messages and stack traces.
    PRIMARY KEY (id),
    KEY (sysbench_run_id
  );

* Generate a report out of the numbers
This script will generate a HTML version for putting up on the web and a
txt version for email usage.

For HTML version additionally generate a graph with JPGraph.

* Get machine(s) and run the test on a weekly basis and for each release
comparing with the prior release.

* Email weekly reports and blog about it.
