Hello,

a) The term 'target' is only regarding the contact with a server
(--server=url1,url2,...) or is it also used for local destination
(--local=absolute_path)? In other words, the options --server and
--local indicate both 'targets'?
Yes. As well as --stdout. Hence the man page or --help output:
Usage: fusioninventory-agent [options] [--server server|--local
directory|--sdout]
Target definition options -s --server=URI send tasks result to a
server -l --local=DIR write tasks results in a directory
--stdout write tasks result on STDOUT
Understood. 'Target' is any destination of the result of the tasks.
Usage:
fusioninventory-agent [options] [targets]
Target definition options
-s --server=URI[,URI[...]] Remote targets. Send tasks
result to a server.
-l --local=<absolute_path> Local target. Write tasks
result in a local directory.
--stdout Local target. Write tasks
result on STDOUT.
And one thing is the 'Target' and other thing is the 'Execution mode'.
b) Regarding with options --delaytime, --wait and --lazy
b.1) All of them have sense only whether FusionInventory Agent runs
in Server Mode, isn't it?
No. Actually, --wait and --lazy are only used in the other execution
mode (explicit name still needed), as explicitly said for the last
one in description. I guess the main purpose of --lazy is to run the
agent manually alongside an already running agent daemon, without
sending additional reports to the server.
[...]
Understood.
--delaytime, in server mode execution only (background mode).
--lazy, in no server mode execution only (foreground mode).
--wait, in no server mode execution only (foreground mode).
Now I understand much better the purpose of --lazy. It's a clever way
to launch fusioninventory-agent in a foreground mode -with local targets
defined- without disturb any other fusioninventory-agent in a background
mode -with remote targets defined- which was running previously.
b.2) Does --wait come into play with local targets (option --local)
or only with remote targets (option --server)?
Any target.
Sorry Guillaume, one thing is the 'Target' and other thing is the
'Execution mode'.
By the way, Gonéri Le Bouder says it makes no sense nowadays
(http://forge.fusioninventory.org/issues/1701)
b.3) If b.1 is true then there is an error in the official
FusionInventory Agent documentation (http://search.cpan.org
/~fusinv/FusionInventory-Agent-2.2.2/fusioninventory-agent).
[...]
Wrong. See code in case of doubt: getNextTarget method, in Scheduler
class.
However, --wait description should have the same mention as --lazy.
Something like "This option is only available when the agent runs in
foreground mode".
c) Regarding with option --backend-collect-timeout
c.1) What are exactly the 'inventory modules'? I know there are
tasks (Inventory, WakeOnLan, ESX, NetDiscovery, NetInventory and
Deploy) but I don't know what are 'inventory modules'.
The inventory task is implemented as a set of independant piece of
codes, which are called modules in Perl world. Indeed, that's a poor
vocabulary.
c.2) Are 'inventory modules' the same than 'tasks'?
No, rather task sub-components (sub tasks ?)
c.3) Is backend-collect-timeout the timeout for all 'inventory
modules' or only for some of them?
For all.
This have arisen me new doubts. We have Tasks and Sub-Tasks but then
c.4) Which is the dependence structure of them?
c.5) There is a hierarchy of Tasks? What is it?
c.6) Is --backend-collect-timeout the timeout for the hierarchy like
a whole or is only for a branch of it?
Documenting the agent is quite difficult, [...]
In general, any documentation process is difficult and tedious. ;)
[...] Any additional contribution in this direction is welcome.
Yes I know it.
BTW, Walid also manifested its interest about those issues:

Thanks for the information.
Thanks in advance. Best regards.
