I want to present an add-on that I developed on Cacti-0.8.6f. Actually, I needed an advance
export graph format. The patch that I propose uses the Cacti graph tree.
In the cacti_export_path, for each tree, a directory is made. For each branch, there is a new
html file generated. And on the left, the tree is showed, with the javaScript used in Cacti.
Only graphs that are enable to export attached on the Cacti graph tree will be really exported.

The attached patch against cacti 0.8.5a adds the 'SIMILAR_DATA_SOURCES_NODUPS' special
data souce as a possible CDEF input for graph template items. This makes it possible to
graph several different types of data on the same graph (eg. traffic_in and traffic_out),
and have totals for each type of data without having to write one-shot CDEFs to handle each
and every total. This really speeds up the generation of aggregate graphs where more than
one data type is being graphed. (Check out the attached graph to see what I mean.)
To use:
1. Define a CDEF that uses the SIMILAR_DATA_SOURCES_NODUPS special data source.
2. Create a graph template with a couple data sources of similar type (and associated
graph template items.)
3. Create a graph template item with the above CDEF, and with the same data source type
as above and it will be the sum of the above.
4. Add any different data source type you want and it won't affect the above sum.
(And yes, you can interchange steps 3 and 4 above.)

Cacti's export function was buggy in cacti 0.8.5a, and lacked extra functionality.
The patches presented here allow extra graph export options.
Changes since Cacti 0.8.5a
Cacti Settings has now a new tab (called Export) where you can choose when to export
the graphs (Export timing). Options are:
* Disable - there will be no graph export
* Classic - export every x times - the default in cacti 0.8.5a
* Hourly at specified minutes - every hour at xx minutes past the hour (eg: 35)
* Daily at specified time - every day at the specified time (eg: 23:55)
The second new option is Export method:
* Classic - graph exporting will be done localy, on the host computer
* FTP using the PHP built-in funtions - only available to users that built PHP with FTP support
* FTP using the ncftpput client - for users which don't want to use PHP's built-in FTP support,
and have the ncftpput binary installed.

Bonsai is very similar to Cactistoric developed by Bruno Prigent, with a little bit
more user friendly interface in mind (my opinion).
Select in the graph (with your mouse) an area you are interested in. It's magic...
the selected time period is displayed in a new graph, and with the left mouse
button zoom out to view a larger time period.
You can also add the displayed graph to your favorites in your browser.

Added 3 new CDEF special types:
Type Description
---- -----------
3 Total staggered datasources.
4 Average all datasources.
5 Average staggered datasources.
Staggered datasources are determined by parsing graph item value
column in the following manner:
start=<starting position in datasource>&skip=<skip count>

Added additional screen help text to support value expanded usage.
