Blank graphs after migration

Post by f0rcedinductn »

Hello,

I migrated an old cacti install off a failing server. I have the new install all setup but I'm not seeing any data on the graphs. I fallowed the migration guide, and did some googling but still no luck.

I am running Cacti version 0.8.7g on ubuntu 10.04 let me know if you need any more info.

Thanks in advance!

A couple of screenshots of your problem would help, as there can be quite some reasons and locations where you are not seeing data.

Did you move the rrd files to the proper location, and are their permissions all right?

Were and are you using the Ubuntu package for cacti (the location might be different, so if you followed the guide to the letter, things are now in the wrong location).

I did move the .rrd files. I'm not sure if the permissions are right, this is what they look like:
-rw-r--r-- 1 www-data www-data 111208 2012-05-28 02:05 woodside_wan_traffic_in_41.rrd

I am not using the ubuntu package of cacti (maybe I'm missing a dependency?), I have the files in /var/www/cacti/

Screenshot of cacti is attached.

Most likely they rrd files are searched in a different location. What does the debug tell you? (Press the wrench next to where the graph should be).

Cool, I didn't know the wrench was for debug :)

Here is the output of one of the graphs:

No last comment off rrdtool? I thought it would be there. Anyway, what happens if you run this on command line, replacing the first hyphen with a (temporary) filename?

Comment off rrdtool? And run what command? Sorry if I missed it.

I would expect (but can not currently test myself if it is true) that under the code above, there is a statement from rrdtool saying everything is all right, or, more likely what the current problem is. As you didn't copy it, I proposed to generate it yourself. So copy the statement above, replace the first hyphen with a dummy file name (e.g. /dev/null) and see what errors or other output are generated when you run the full command in a terminal (command line).

Sorry I misunderstood, I just ran the command I'm guessing this is the problem:
ERROR: This RRD was created on another architecture

The above is true the old server was 32bit the new server is 64bit. Is there anything I can do to fix this? I didn't know this would be a problem (and completely forgot the old server was 32bit).

If you still have a 32bit computer available, yes. Search the forum or docs. E.g. post 19026

Thank you for your help paulgevers!

I also found this link, which had scripts that made the mass-export/import much easier :)

http://docs.cacti.net/manual:087:4_help ... hitectures

Thanks again!
