1) Search! many people have created these

2) read in the documentation site on how to create the script/templates.

I fear you've got the concept of data queries wrong. It seems, as if you want to create a data query for a "simple SNMP value". That's nogo. Please see walkthroughs of my first sig link to get the idea.

I fully agree with Reinhard.

If you want to graph a single OID (or even several), you can use the "SNMP Generic OID" templates.

I've always the same problem. I don't know why

Can you :

go to data sources
click add
select the "SNMP - Generic OID template"
fill the "Name' and 'OID' fields, and adjust the maximum value
save
go to graph manament
click add
select the "SNMP - Generic OID template"
fill the "Legend" and "Title" fields
point to the data source previously created

That should work

There's even a document for that : http://docs.cacti.net/node/495

I'm not sure that I understand the difference between data query and data source...

From http://docs.cacti.net/node/225

What is a Data Query? Here's the text from cacti's website (Chapter 10. Data Queries):

Data queries are not a replacement for data input methods in Cacti. Instead they provide an easy way to query, or list data based upon an index, making the data easier to graph. The most common use of a data query within Cacti is to retrieve a list of network interfaces via SNMP. .... While listing network interfaces is a common use for data queries, they also have other uses such as listing partitions, processors, or even cards in a router.

One requirement for any data query in Cacti, is that it has some unique value that defines each row in the list. This concept follows that of a 'primary key' in SQL, and makes sure that each row in the list can be uniquely referenced. Examples of these index values are 'ifIndex' for SNMP network interfaces or the device name for partitions.
There are two types of data queries that you will see referred to throughout Cacti. They are script queries and SNMP queries. Script and SNMP queries are virtually identical in their functionality and only differ in how they obtain their information. A script query will call an external command or script and an SNMP query will make an SNMP call to retrieve a list of data.

All data queries have two parts, the XML file and the definition within Cacti. An XML file must be created for each query, that defines where each piece of information is and how to retrieve it. This could be thought of as the actual query. The second part is a definition within Cacti, which tells Cacti where to find the XML file and associates the data query with one or more graph templates.

You don't need to create a data query to graph only a few OIDs...
