rrdtool error

[emiel]

hi all,

im quite lost right now..i did for about the 6th time an complete reinstall of cacti.
this time i installed cacti 0.8.7d manual by following this tutorial (http://www.ubuntugeek.com/networkserver ... erver.html) on an ubuntu 9.04 x64 server edition.

Everything (seems) working, i can logon to my cacti, i can create an host, etc, etc

but when i create graphs for my host i still get this error message

Code: Select all

RRDTool Command:

RRDTool Says:

ERROR: opening '/var/www/cacti/rra/localhost_load_1min_5.rrd': No such file or directory

the rights at the directory rra/ log/ are as follow:

Code: Select all

drwxr-xr-x  2 www-data www-data 4.0K 2009-02-12 03:55 rra
drwxr-xr-x  2 www-data www-data 4.0K 2009-02-12 03:55 log

another thing that is weird about this is that when i look in devices, i see that status says: Unknown.
but when i click on the server i am getting the right SNMP information and the ping says that it is succesfull.

i tried many things, looked around forums, did many reinstalls, but im still stucked with the error message that RRDtool is giving me.

what can i do to get this working?

thnx in advance!

If you look at the Cacti installation instructions, you need to do the following:

Code: Select all

chmod -R 777 /var/www/html/cacti/log /var/www/html/cacti/rra

This should fix things.

[emiel]

already did that but that doesnt work...

[TheWitness]

What "doesn't work"? Provide a screen shot of Graph Debug.

[emiel]

as i mentioned in my start post, rrdtool is giving an error and the device has the status of unknown...

i have added 2 screens hope you can do something with it..

[TheWitness]

Well, this is quite strait forward. Everything is, in fact working. However, for some reason, the file does not exist. The trouble shooting steps require you to verify that the Poller Cache has entries to collect the data and that the poller is running and has the correct permissions to the rra directory. Setting the directory permissions to 777 always helps.

Once the file is created, we may get other error messages. You might want to select on of those.

TheWitness

[emiel]

so you mean that i just have to wait a while untill the file has automatically been created?

[TheWitness]

The fact that the device is in an unknown status means to me that the poller cache is not being populated properly. Please "Resave" the device to force the repopulation of the poller cache. You might want to verify that it has entries. In addition, you need to verify that the poller is actually running.

I saved it again, is there a way to see if the poller is running correctly?

[gandalf]

Please change crontab and pipe poller output to e.g. /tmp/poller.log instead of /dev/null. Then, watch that file

From what I read, I suspect your problem is in the Ubuntu install of cacti.

The rrd files are located at /var/lib/cacti/rra/

This will have been implemented when you did the apt-get install following the Ubuntu Geek instructions - this is how I did it.

But, when you do the manual download of 0.8.7d, there are missing patches to config.php, global.php and global-settings.php

See http://patch-tracking.debian.net/package/cacti/0.8.7d-1

Have you done these debian/Ubuntu specific patches?

If yes, ignore my posting, but if no, or you would like to walk through a working build, I have a full tutorial on our web site.

Hope this helps, let me know

I did this time an manual install, and installed 0.8.7d.
when i install it from the ubuntu repo's it is installed in /usr/share/cacti/site/rra

i havent installed the patches, going to try it!

[aldibi]

I believe the patches are only applicable if you have done an install using sudo apt-get install cacti-cactid.

If this is what you do, you will get version 0.8.7b installed

rrds will be in /var/lib/cacti/rra ( there is a directory /usr/share/cacti/site/rra - but it is not where the files will be placed)

logs will be in /var/log/cacti/

crontab is at /etc/cron.d/cacti

[emiel]

ok, i did an manual install, where will the rra files be placed?

my cacti install dir is /var/www/cacti/

[emiel]

well...i started over again..and followed your tutorial from begin till end!
when i now create a device and have the graph debug mode on, it says

Code: Select all

RRDTool Says:

OK
