[hobbit] mysql monitor
Hi,
I've done all of that and I didn't get it to work ! Is there another thing to do ? I'm looking at the man-page (hobbitd_rrd) but it's the same example ! I put the line NCV_mysql="Uptime:NONE,Queriespersecondavg:GAUGE" into hobbitserver.cfg but what can I do to have the corresponding graph appear in "trends" ? Thanks a lot for your help !

Looks like I've got these:

The status line from one host reads: Uptime: 5421958 Threads: 1 Questions: 1051219 Slow queries: 577 Opens: 80325 Flush tables: 189 Open tables: 63
The Uptime value is discarded and the rest go into the mysql.rrd. Only the "Slow queries" and "Thread" graphs show on the Trends page.
It may not be optimal, but I am getting graphs... :)

Hmm... I just downloaded the current bb-mysqlstatus.tar.gz from deadcat.net , diffed bb-mysqlstat.sh against the one I have running on a hobbit server, and the only change I made was to replace VALIDMYSQLUSER & VALIDMYSQLPASSWORD.

Hi Thomas,
We have the mysql monitoring working since yesterday and yes, this was painfull to set up for us too ;-)
There is a good reference "How to" (howtograph.html) in the help dir. of your Hobbit installation.
Here below the necessary configuration steps using snapshot of 31 mai.
- Modify bb-mysqlstat.sh
The status $MYSQLADMIN returned by the original script is not suitable for the NCV module. You have to modify it to return Name:value pairs each on a single line. After extracting the values from $MYSQLADMIN (awk), we send this to the Hobbit server:
$BB $BBDISP "status $MACHINE.$TEST $COLOR `date` - $STATUS$UPTIME $THREADS $QUESTIONS $SLOWQUERIES $OPENS $FLUSHTABLES $OPENTABLES $QUERIESPERSECONDAVG "
- Get clientlaunch (hobbitlaunch if your on the server) to run the script
[mysql] ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg CMD $HOBBITCLIENTHOME/ext/bb-mysqlstat.sh LOGFILE $HOBBITCLIENTHOME/logs/bb-bb-mysqlstat.log INTERVAL 5m
- Check that the script data arrives in Hobbit
After a few minutes, a mysql column should appear on your Hobbit view of this host.
- Arrange for the data to be collected into an RRD file
Modify the TEST2RRD for mysql and set the RRD datatype for the NCV module used for mysql in the NCV_mysql variable.
TEST2RRD="cpu=la,disk,<...lots more stuff...>,hobbitd,mysql=ncv NCV_mysql="*:GAUGE"
- Check that the RRD collects data
You can use "rrdtool dump ~hobbit/data/rrd/HOSTNAME/mysql.rrd" or "rrdtool fetch ~hobbit/data/rrd/HOSTANME/mysql.rrd AVERAGE" to see what collected.
$ rrdtool fetch /soft/pub/BB/hobbit/data/rrd/deca/mysql.rrd AVERAGE Uptime Threads Questions Slowqueries Opens Flushtables Opentables Queriespersecondavg
1149067800: NaN NaN NaN NaN NaN NaN NaN NaN ... ... 1149153300: 1.7361796133e+06 1.2386666667e+01 1.3905225373e+07 2.7000000000e+01 8.3400000000e+02 1.0000000000e+00 1.2100000000e+02 8.0089200000e+00 1149153600: 1.7364796000e+06 1.2200000000e+01 1.3911530100e+07 2.7000000000e+01 8.3400000000e+02 1.0000000000e+00 1.2100000000e+02 8.0113000000e+00 1149153900: 1.7367795867e+06 1.3826666667e+01 1.3915204080e+07 2.7000000000e+01 8.3400000000e+02 1.0000000000e+00 1.2100000000e+02 8.0122933333e+00 1149154200: NaN NaN NaN NaN NaN NaN NaN NaN 1149154500: NaN NaN NaN NaN NaN NaN NaN NaN
- Set up a graph definition
If your are interested in tracking the active threads, cut and paste the [mysqlthread] section of hobbitgraph.cfg and give it the [mysql] tag.
Refresh the status page in your browser, and the graph should show up.
- Add the graph to the collection of graphs on the trends column
If you want the graph included with the other graphs on the trends column, you must add it to the GRAPHS setting in the ~hobbit/server/etc/hobbitserver.cfg file.
GRAPHS="la,disk,<... lots more ...>,bbproxy,hobbitd,mysql"Save the file, and when you click on the trends column you should see the mysql graph at the bottom of the page.
8 Optional: add more mysql graphs to the trends column
In bb-hosts, you can set TRENDS for displaying -here beside mysql- other mysql-graphs defined in hobbitgraph.cfg.
Example definitions in hobbitgraph.cfg:
[mysqlslow] DEF:slow=mysql.rrd:Slowqueries:AVERAGE TITLE MySQL Slow Queries YAXIS # LINE2:slow#FF0000:Slow Queries GPRINT:slow:LAST: \: %5.1lf (cur) GPRINT:slow:MAX: \: %5.1lf (max) GPRINT:slow:MIN: \: %5.1lf (min) GPRINT:slow:AVERAGE: \: %5.1lf (avg)\n [mysqlqueries] DEF:quer=mysql.rrd:Queriespersecondavg:AVERAGE TITLE MySQL Queries Per Second Average YAXIS # LINE2:quer#0000FF:Queries Per Second Average GPRINT:quer:LAST: \: %5.1lf (cur) GPRINT:quer:MAX: \: %5.1lf (max) GPRINT:quer:MIN: \: %5.1lf (min) GPRINT:quer:AVERAGE: \: %5.1lf (avg)\n
Example bb-hosts entry:
1.2.3.4 HOSTNAME # TRENDS:*,mysql:mysql|mysqlslow|mysqlqueries
Hope this helps.
