zabbix lld - control the order of detection (docker containers)

[yogi]

Hi,
I am running zabbix 3.01.
Currently i am monitoring some docker contaniners using LLD.
My LLD script just does: "docker ps" and get all the running docker containers.
When a new container detected by the LLD, i am running some exteranl script.
My problem is that zabbix does not activate the exteranl script in the same order my LLD discover the container. How can i control this?
for example:
If my LLD discover the followings (get them as a list in the followings order) :
time 0 - container-1
time 1- container-2
time 2- container-3
I want zabbix to activate the exteranl script in the same order:
exteranl script of container-1
exteranl script of container-2
exteranl script of container-3
but in the real world my zabbix mixed the order:
exteranl script of container-3
exteranl script of container-1
exteranl script of container-2
thanks!
