problems with SuSE 9.3 and smokeping configuration

Hello!

I have problems to run smokeping. In SuSE Professional 9.3 I have
installed the rrdtool package.
Fping is running (tried manually) and also smokeping is running in
daemon mode.
But I guess, something with the paths in etc/config and bin/smokeping is
wrong and not fitting with the standard-paths of SuSE Linux, e.g. the
path for the lib of rrdtool.
When starting smokeping cgi with http://localhost/cgi-bin/smokeping.cgi
I get the structure on the left side, but no grafics (*.png).
Did somebody already installed smokeping under SuSE and can help me with
some sample configuration files.

Many thanks

Michael

extremely slow smokeping execution speed


I'm having a problem with the smokeping binary, and the .cgi script, being 
extremely slow on a moderately fast system (Athlon1200, 512RAM.)  Top is 
showing almost no CPU or disk utilization while it's running.  Softwares:

OS: Slackware10.1
smokeping: 2.0rc5
perl: 5.8.7
rrd:  1.2.10
echoping: 5.2.0

everything else should be per the smokeping recommended versions.  My 
config file has about 15 hosts, being probed with echoping http, https, and 
smtp.  Only two hosts are probed with fping.

I ran the perl profiler on it (bear with me; I'm not a coder) and it gave 
me this info:

root <at> pathmon:/usr/local/smokeping/bin# dprofpp tmon.out

Scripting to summarize smokeping rrd data

I was wondering if someone could point me the right direction to
accomplish the following.  I'd like to produce an average of the last 30
days of RTT data for a ping test done by smokeping.  I would like to
email myself that number as there is no need for any graph.  I know this
number isn't particularly relevant, but it will help with some
statistics I need to produce.

Is there a way to use "rrdtool fetch" to extract this number from the
smokeping rrd files?

rrdtool fetch and a few lines of <gawk,perl,php,...> should do. E.g. 
rrdtool fetch test.rrd AVERAGE -s -30d-e | ...

Re: Scripting to summarize smokeping rrd data

Thank you.  Now that I have the data, 2 questions.

What is the best way to manipulate those numbers in exponential
notation?  I need them in decimal notation.

Those few lines of <gawk,perl,php,...> you speak of, can you point me
the direction of some examples?  It seems I don't need to do much more
than sum the median column and divide by the # of rows.  However, my
scripting isn't good enough to do that w/o some examples.

Tony

typically $language will already do for you.

First a warning: summing  the median and dividing by numbers of summands 
gives you what? imho only useless information. But anyway. A q&d awk 
script would look like

/^[0-9]/	{ s += $4; n++ }
END	{ print s/n }

If you really want to have the median of the last thirty days, 
recalculate them for yourself.

newbie q:

Hi, sorry if this has been covered; I can't seem to find any documentation
to suggest a solution:

I'm trying to spiffy up my graphs.  I realized that all the demo RRD graphs
and even the demo graphs on the smokeping site are much nicer looking than
mine.  How do you use font smoothing and other custom color and
anti-aliasing features on the graphs themselves?  I can't seem to locate
where I can mess with the rrdgraph parameters.  Any help or documentation I
can read is appreciated.  Best,

-Matt

RRDtool2 and freetype2 make possible the purty fonts.  From what I 
understand you can't use rrdtool2 with the older (1.x) versions of 
smokeping, if that's what you're currently running.

Hi,

are you still seeing these? Which 2.0 version are you using? If it's the
latest (rc5), could you please send me your config so I can try to
recreate this?

Cheers,

Re: Smokeping 2.0 Uninitialized Value

Hmmmm... how do I tell:
$VERSION="1.99004";
my $RCS_VERSION = '$Id: Smokeping.pm,v 1.5 2004/10/21 21:10:51 oetiker
Exp $';

I'll d/l the latest and give it a go.
