[leiw]

Hi,

I'm new on Cacti, I completed the installation but cannot see any
picture in web interface, I don't know what packages I missing,
the following what I installed for Cacti:

net-snmp
php-snmp
freetype-devel
libpng-devel
libart_lgpl-devel
net-snmp-utils
gd
php-gd

I maybe forget some packages.

How can I enable Graph DEBUG Mode ?

[gandalf]

Goto Graph Management, select your graph and turn on the DEBUG mode by clicking the text in the upper right corner

Please can you help me to explain what the debug mode said ?

RRDTool Says:

sh: /usr/local/bin/rrdtool: is a directory

[gandalf]

You've got the wrong path to the rrdtool binary. Visit Settings -> Paths and eneter the /full/path/to/rrdtool/binary. And set Settings -> RRDTool Utility version to the version that's received when entering

Code: Select all

/full/path/to/rrdtool -v

at the command line

Ok, I fixed the rrdtool path problem, but have another problem ...

when I click Graph Management > Localhost - Load Average > the

Graph Debug Mode said :

ERROR: opening '/home/chris/public_html/cacti/rra/localhost_load_1min_5.rrd': No such file or directory


How can I create the localhost_load_1min_5.rrd directory ??

Thanks

[gandalf]

rrd files are created by the poller. Installation requires to edit the crontab to start the poller every 5 min. Please post a copy of your crontab to check

To gandalf,

Thank you, I can see graphs now, one more question how can

setup monitor smtp, http, ftp etc network traffic ?


Thanks

[gandalf]

This question was already asked lots of times. You may search for ipfilter, ntop, flowscan to find some of them
