[dev] info to develop a custom module

[Luca Borsari]

Hi there.
I need to extract some stat info (ex: Agent avg. ticket lead time, etc)
from our otrs server, to monitor/improve our support service.
Reading old posts to ADMIN/DEV lists, and lloking at the docs,
 i've found the DB tables storing the info i need.

I could make a perl scipt to extract data and produce the
stat i need, but i would rather prefer to implement it
directly in OTRS, as a custom module (OTRS web application framework)

Looking at the online Developer Manual, it seems to me that the
process to do that will be something like:
  *) Create a custom frontend module (in Kernel/Modules/)
  *) Create the HTML (dtl) to manage input parametrs
  *) Create the HTML (dtl) to generate output
  *) Modify Agent menu to include the new link (button)

being new to otrs hacking, my first question is...am i doing something
completely wrong...?

What it would be great for me to have at this stage, is a sort of
"beginners otrs dev guide", implementing an hello word like feature using
the OTRS web devlopment framework.


Any clue?

TIA
