Duplicated Data Sources in Cacti 0.8.6f

[wonka]

Hi everyone,

Here´s the scenario:

Fedora Core 3
PHP 4.3.9
cacti 0.8.6f

After creating a new graph I got the poller.php error

07/28/2005 01:31:52 PM - POLLER: Poller[0] CACTI2RRD: /bin/rrdtool create /var/www/html/admin/cacti/rra/localhost_bytes_22.rrd --step 300 DS:bytes:ABSOLUTE:600:0:U DS:bytes:ABSOLUTE:600:0:U 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
ERROR: Duplicate DS name: bytes

07/28/2005 01:31:52 PM - POLLER: Poller[0] CACTI2RRD: /bin/rrdtool update /var/www/html/admin/cacti/rra/localhost_bytes_22.rrd --template bytes N:102266
ERROR: opening '/var/www/html/admin/cacti/rra/localhost_bytes_22.rrd': No such file or directory

Ok. After searching a while, found a suggestion that this could be caused by a duplicated entry when creating the rrd file. So tried manually creating the rrd file, removing the duplicated DS:bytes:ABSOLUTE:

/bin/rrdtool create /var/www/html/admin/cacti/rra/localhost_bytes_22.rrd --step 300 DS:bytes:ABSOLUTE:600:0:U 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

And after that, poller.php returned no errors and the graph was created.

QUESTIONS:

1. Why this duplicated entry appeared? Is this a bug still unsolved?
2. Is there a way to resolve this without manually creating the rrd file each time?
3. In Graph Template section I see a duplicated Data Source on the Graph item fields. How can I remove this duplicated entries? Why I get duplicated entries?

Thanks for any comments

Update:

After checking a while I found that the Custom Data area in the Data template I´m using, had two tabs, like this:

| 1 bytes X | 2 bytes X |

I deleted one clicking on the X and now it seems to be working fine. But still the question remains, now with the form:

"Why did the custom data duplicated if I didn´t duplicate it?".

Thanks

It's a validation issue that was supposed to be fixed in 0.8.6f. Thanks for the note.
