Is there a new installation guide for installing the new Cacti version onto Ubuntu 9.04 Server Edition? or should i just follow the old version installation guide?

Follow the guide here

Then update the database and application by hand.

Thanks. I got the Cacti installed on the server hardware. It took a while to get it to work. However, i am missing some files and was not able to pull and graphs. I noticed under my Setting and Path... the SNMPWALK file was not found among several others. Not sure if it didn't get installed from the package file i got.... can I add these files manually? Here is a screenshot on my setting page. Please advice.
PS. I have another Cacti box that is functional. Can I just copy the SNMPwalk file from that machine to the server? Would that work?

Hmm, that doesn't look good. Seems like RRDTool and Net-SNMP didn't even get installed ! Did you install Cacti from source, or from packages ?

From terminal, type

sudo apt-get install rrdtool
sudo apt-get install librrds-perl
sudo apt-get install snmpd

These commands above should install RRDTool and Net-SNMP - hopefully, iy'll cure the problems you seem to be experiencing.

Yeah.. right after i posted my problem. I used

Code: Select all

whereis

command to see if i can find these files. They were not exist in any directories. So i installed these packaged and all the files are "found". I added the local hosts and a test switch and see if they graphs are showing. I am giving it 5 mins and see if it polls any graphs at all. Is there a command you can check that Cacti is polling any information from the networking devices?

[mcutting]

Well, if you installed from packages, the user for the poller is www-data. I would do a "crontab -e" and see if there are any entries for the poller. Check the logs also (use LOW) and see if any entries are placed there.

The worst part is over (hopefully), and if the poller is running, you should be good to go.

Ok.. so, i did some debugging on my test switch. It seems like its working.

Code: Select all

Data Source Debug

/usr/bin/rrdtool create \
/var/www/cacti/rra/test_switch_traffic_in_9.rrd \
--step 300  \
DS:traffic_in:COUNTER:600:0:1000000000 \
DS:traffic_out:COUNTER:600:0:1000000000 \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 \

However, when i check the log file....

Seems like RRDTool is segfaulting - can you post the result of

which rrdtool

Thanks

EDIT: have you also checked the permissions for your RRA directory ? You need to make sure that your poller account has write access

Also, have a look at http://forums.cacti.net/about32542.html&highlight=

Might also make sense to set your poller into DEBUG for one pass, and submit a copy of the log here.

[cjblade54]

Here is the result after i typed "which rrdtool"
/user/bin/rrdtool

[mcutting]

Ok. Please see my other posts - particularly the one concerning permissions.

[mcutting]

Here is the result after i typed "which rrdtool"
/user/bin/rrdtool

Are you sure that it's not "usr/bin/rrdtool" ?

[cjblade54]

Here is the result after i typed "which rrdtool"
/user/bin/rrdtool

Are you sure that it's not "usr/bin/rrdtool" ?

LOL.. yeah.. its is /usr/bin/rrdtool

[mcutting]

Ok - could you also do

From terminal

cd /usr/share/cacti/site/rra

ls -ln

Post output

Thanks
