Log only objects changes / remove storage files

[gtsamis]

The only solution that I see is that you create another object for each one you want to log and then filter the input value in an event script.

Add this to Common functions:

Code:

function checkupdate(sendto, mindelta)
 -- event value
 local newvalue = event.getvalue()
 -- current object value
 local curvalue = grp.getvalue(sendto)
 -- absolute delta between event and current value
 local valdelta = math.abs(curvalue - newvalue)
 -- send if delta value is large enough
 if valdelta >= mindelta then
   grp.update(sendto, newvalue)
 end
end

Create an event script for each object where you want to log only value changes. 1/1/1 is your "virtual" object which is logged, 2 is minimum delta between current "virtual" object value which causes new value to be sent. Adjust as needed.

Code:

checkupdate('1/1/1', 2)

As for storage, do you mean script storage? In newer releases it's stored in a separate database and there's no easy way to delete some of the entries unless you know all of their names. You can only do a full clear operation.

Thank you for the answer, unfortunately for object logging it doesn't seem optimized solution, probably i will switch to general logging where i can filter what and when to log it.
By the way, is there any way i could check objects previous state before the database update and without using storage?


For the second question I mean storage used by storage.get and storage.set
Thank you in advance
