installation de fping par rpm : rpm -i fping-2.4-1.b2.1.el3.rf.i386.rpm dl : wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.3.5.tar.gz copie : tar -xvzf smokeping-2.3.5.tar.gz && mv smokeping-2.3.5 /usr/local/ && ln -s /usr/local/smokeping-2.3.5/ /usr/local/smokeping && cd /usr/local/smokeping

installation de SpeedyCGI : recuperer les sources sur http://www.daemoninc.com/SpeedyCGI/ puis le classique : perl Makefile.PL && make && make test && make install

installation de rrdtool : wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.2.27.tar.gz && tar -xvzf rrdtool-1.2.27.tar.gz && cd rrdtool-1.2.27 && ./configure --prefix=/usr/local/rrdtool && make && make install

configuration pour bin/smokeping

mv bin/smokeping.dist bin/smokeping

puis il faut modifier les lignes concernant le perl, les libs rrd et celle de smokeping et le fichier de conf dans mon cas ca a donne ca :

#!/usr/bin/perl -w
...
use lib qw(/usr/local/rrdtool/lib/perl/5.8.0/);
use lib qw(/usr/local/smokeping/lib/);
...
Smokeping::main("/usr/local/smokeping/etc/config");

pour htdocs/smokeping.cgi

mv htdocs/smokeping.cgi.dist htdocs/smokeping.cgi

de la meme facon il va falloir modifier ce fichier ce qui donne de mon cote :

#!/usr/bin/speedy -w
...
use lib qw(/usr/local/rrdtool-1.2.27/lib/perl/5.8.0/));
use lib qw(/usr/local/smokeping/lib/);
Smokeping::cgi("/usr/local/smokeping/etc/config");

pour etc/config

# good for images.
imgcache = /usr/local/smokeping/smokeping-ms/cache

*** Alerts ***

comment = loss 3 times  in a row

+bigloss

*** Database ***

# 4 pings toutes les minutes

*** Presentation ***

template = /usr/local/smokeping/etc/basepage.html

+ charts

menu = Charts
title = The most interesting destinations

++ stddev
sorter = StdDev(entries=>4)
title = Top Standard Deviation
menu = Std Deviation
format = Standard Deviation %f

++ max
sorter = Max(entries=>5)
title = Top Max Roundtrip Time
menu = by Max
format = Max Roundtrip Time %f seconds

++ loss
sorter = Loss(entries=>5)
title = Top Packet Loss
menu = Loss

+ overview

width = 600
height = 50
range = 10h

+ detail

width = 600

unison_tolerance = 2

"Last 3 Hours"    3h
"Last 30 Hours"   30h
"Last 10 Days"    10d
"Last 400 Days"   400d


*** Probes ***

+ FPing

binary = /usr/sbin/fping

*** Targets ***

probe = FPing

menu = Top
title = Network Latency Grapher
remark = my first smokeping conf

+ EXT
menu = Exterieur
title = vers l'exterieur

++ Google
host = www.google.com

++ Weborama
host = www.weborama.com

++ Yahoo
host = www.yahoo.fr

Dans mon cas etc/basepage.html devait etre modifie ainsi :

...
<script src="/smokeping/lib/prototype.js" type="text/javascript"></script>
<script src="/smokeping/lib/scriptaculous.js?load=builder,dragdrop" type="text/javascript"></script>
<script src="/smokeping/cropper.js" type="text/javascript"></script>
<script src="/smokeping/smokeping-zoom.js" type="text/javascript"></script>
...

Puis pour que tout ceci soit conforme j'ai declare ceci dans mon apache (typiquement /usr/local/httpd:/conf/httpd.conf) :

############################################
#Smokeping : supervision ping
############################################
ScriptAlias /smokeping/cgi-bin "/usr/local/smokeping/htdocs/"

<Directory "/usr/local/smokeping/htdocs/">
   Options ExecCGI Indexes FollowSymLinks
   AllowOverride None
   Order allow,deny
   Allow from all
</Directory>

Alias /smokeping/cache "/usr/local/smokeping/smokeping-ms/cache/"

<Directory "/usr/local/smokeping/smokeping-ms/cache/">
        Options Indexes FollowSymLinks
        AllowOverride None
        Order allow,deny
        Allow from all
</Directory>

Alias /smokeping "/usr/local/smokeping/htdocs/cropper/"

<Directory "/usr/local/smokeping/htdocs/cropper/">
        Options Indexes FollowSymLinks
        AllowOverride None
        Order allow,deny
        Allow from all
        RewriteEngine on
        RewriteRule   ^/.* /smokeping/cgi-bin/smokeping.cgi
</Directory>

ensuite... bah c'est fini ! enfin presque ! il faut lancer

pour lancer le daemon smokeping : /usr/local/smokeping/bin/smokeping --config=/usr/local/smokeping/etc/config --debug et si tout est bon /usr/local/smokeping/bin/smokeping --config=/usr/local/smokeping/etc/config

en vous remerciant ! :)
