RRD's won't populate after server move :S

[sourcecode]

hey guys. i just did a server move for cacti. I imported all the rrd's, dumped and imported the mysql db, and added the poller.php into crontab.
I just don't understand why I can't get cacti to populate and show new data. (although the old data,already in the rrd, did show up)
any ideas?

i've read and re read today ur NaN howto's and can't find the problem. what it seems to me is just that it doesn't update the rrd's.
damn frustrating

i think i saw one problema already. the poller is looking for the scripts in the wrong directory. how could i change the <path_rra> ?

Hi

IMO it's in the settings table, something like this :

Code: Select all

path_webroot   /var/www/html/cacti

[sourcecode]

/var/www/artemis/root/admin/cacti/scripts/ this is wrong and should be /usr/share/cacti/site/scripts/.
how could i change this?

[fmangeant]

I'm using phpmyadmin to change things like that.

<path_rra> is deduced from cacti's installation path, appended is "/rra". There's no settings for that, it's pure code. But why are you asking for <path_rra>, when your scripts path is wrong? <path_rra> points to the rrd file's directory.
Script paths are given under Data Input Method, per script. You may use <path_cacti> as a replacement for cacti's installation path. If you change anything here, please php reuild_poller_cache.php

Hi Reinhard

if you move your Cacti installation from /path1 on one server to /path2 on another server, does this setting gets modified by Cacti ?

[sourcecode]

thats my problem here. i changed it from path1 on server A to path2 on server B and when i passed the rrd's and etc imho they're trying to find the data in path1 of server A and not where it actually is (path2 on server B)

You're typing too fast for me!
AFAIK (did not try), only moving will not change it, cause <path_cacti> is retrieved from Settings->Paths. This will be determined only at startup. But after moving, I suppose, you'll have first to change this settings and then php rebuild_poller_cache.php. This should do, but I never tried on my own
