After editing the hobbitserver.cfg and hobbitgraph.cfg i had some
confrontations with:

how should i configure the parameters of the hobbitserver.cfg and
hobbitgraph.cfg if i want 3 diferent

graphs in one page, when the graph name has to be the same as the column
name?

when trying to get the only graph into the browser i get only an 1x1

Pixel graph...


I can’t help with the multiple graphs on one page; I have mine set up for
one graph on the page.


If you’re intererested, I can send you my version of bb-mysqlstat.sh
(heavily modified from the one available on Deadcat.net …. )


Here are the relevant parts from hobbitserver.cfg:


NCV_mysql="Threads:GAUGE,SlowQueries:GAUGE,OpenTables:GAUGE,FlushTables:NONE,Questions:NONE,Opens:NONE,AvgQuerysPerSecond:NONE,Uptime:NONE,FreeBufferPool:NONE"


GRAPHS="la,disk,inode,qtree,files,processes,memory,users,vmstat,iostat,tcp.http,tcp,ncv,netstat,ifstat,mrtg::1,ports,temperature,ntpstat,apache,bind,sendmail,mailq,socks,bea,iishealth,citrix,bbgen,bbtest,bbproxy,hobbitd,clock,lines,mysql"


Here is the stanza from my hobbitgraph.cfg for the mysql graphs:

[mysql]

        TITLE MySQL Statistics

        YAXIS Number of

        DEF:threads=mysql.rrd:Threads:AVERAGE

        DEF:slow=mysql.rrd:SlowQueries:AVERAGE

        DEF:opentables=mysql.rrd:OpenTables:AVERAGE

        LINE2:threads#FF0000:Threads

        LINE2:slow#00CCCC:Slow Queries

        GPRINT:opentables:MIN: \: %5.1lf (min)

        GPRINT:opentables:AVERAGE: \: %5.1lf (avg)\n


The client side extension script sends up the information which is then
displayed as:
*Wed May 27 10:12:53 EDT 2009 - mySQL is OK*

Threads            : 10

AvgQuerysPerSecond : 2.455

Uptime             : 33923

Hope this helps,

Hi guys,


im trying to monitor some mysql performances like slowqueries, threads,
queries per second, etc. trought an external script. So far i get all
results from the client (Big Brother-Client) unless the graphs. Using big
brother (server) i get 3 graphs (slowqueries, threads and queries per
second) but after migrating BB to Hobbit i cant get any graph anymore. I
already did all steps from "How to setup custom graphs" but its not working.

Did i forget something / did something wrong or is it with the BB-Client
not possible?


After editing the hobbitserver.cfg and hobbitgraph.cfg i had some
confrontations with:

how should i configure the parameters of the hobbitserver.cfg and
hobbitgraph.cfg if i want 3 diferent graphs in one page, when the graph name
has to be the same as the column name?

when trying to get the only graph into the browser i get only an 1x1 Pixel
graph...

has anybody any idea??

TIA
