[asterisk-users] asterisk calls per second

[Atis Lezdins]

Hi,

I already gave a hint into right direction, but seems that it got
missed, so basically it would look like this:

>> exten=>_3XX,1,Set(GROUP()=${EPOCH})
>> exten=>_3XX,2,Set(GROUPCOUNT=${GROUP_COUNT(${EPOCH})})
>> exten=>_3XX,3,GotoIf($[${GROUPCOUNT} > ${MAX_CALLS}]?120)
>> exten=>_3XX,4,Dial(SIP/${EXTEN})
>> exten=>_3XX,5,Playback(unavailable)
>> exten=>_3XX.,6,Hangup
>> exten=>_3XX,120,Playback(try-later)
>> exten=>_3XX,121,Hangup

Epoch is UNIX timestamp, which changes every second. Probably you
don't even need to use GROUP, but can keep counter for current second
in some database, however that would need database cleanups and locks.
Asterisk builtin DB wouldn't be useful, as it can't increment within
same operation, so some sort of SQL magic should be used. For example
multiple primary keys, one of which is autoincrement, or just
transactions.

However advantage of using GROUP would be that if call disconnects,
it's not counted within GROUP_COUNT anymore, so you can accept one
more call for that second(probably most useful for minute).

Regards,
Atis
