How do you control how many days you can archive and where are they saved too?
In my case I redevelop standart monitoring plugin for archiving only - it`s less memory needed and OF work better. (I called it archiving_lite)
There is no page in admin console. It`s only save messages in SQL database.
So for collect some data from this table or filter messages on ip, passwords logins transmiting over isq (I work in big company, and lookin for private datas transmitted over non-company networks) I wrote sql script.
And it`s fine work for me.
For youre case - use monitoring plugin - it has setting for archive control. also they saved in DB that you are using with OF.
I also would like to control the amount that is archived. It seems that you can only turn it on or off.
