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

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.

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.
Open items:
** Generate an overview table in the form of
Number of threads
1 4 8 16 32 64 128
sysbench test
delete 121.52 144.77 117.70 115.15 100.48 75.39 66.56
mean value of runs
1 first run
2 second run
3 third run
STDEV
STDEV in % of mean
CPU utilization (usr/sys/wait/idle)
IO (read/write)
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.
