datasource length limited to 19 characters?

Badbeeker · Post by **Badbeeker** » Wed Jan 31, 2007 1:50 pm

We are trying to collect some dhcp stat info. Some of the data source names that we are trying to use are longer than 19 characters. Is there a reason why the data source name is limited to this many characters?

I'm trying to edit a data template which has 9 data source items attached to it. I'm not able to enter a data source item name longer than 19 characters.

Could I get away with changing the data_template_rrd.data_source_name field from 19 to 30? I think I would have to edit the php file to allow more than 19 characters as well. Is this a valid fix or would there be more work involved?

I'm using Cacti 8.6h btw.

Does anyone else have this problem? or do people just not use datasource longer than 19 characters?

Try "Settings->Visual" Data Query Field length

it's set to 100.. This is under Data Template -> Data Template Items.. The Name Field under that.

But I meant this one, but I'm not sure if this fits your needs

Sorry for the late reply.. work has been busy. The value that I have for that picture is 100 Gandalf. But it doesn't seem to have any effect on the field that I need increased in length. I have circled the field I need increased in the included picture.

Now I understand, but I haven't got any clue (except for checking the source)

ya didn't want to edit the php file, but It also seems like the database field that holds that value is also limited to 19 characters.. just wanting to know if there is any reason. Also, if I change these two values to a larger length, would that screw anything else up.. guess it's best not to do anything and work around it.

Oh well.

Thanks for the help =)

Hi

I'm afraid this is a RRDtool limitation

:

Code: Select all

DS:ds-name:DST:dst arguments
               ds-name is the name you will use to reference this particular
               data source from an RRD. A ds-name must be 1 to 19 characters
               long in the characters [a-zA-Z0-9_].

This is from the rrdcreate manpage (1.2.18 version).
