Hello Friends,

lets imagine i have following state , i get a message ordered  
timeStamp1,transactionA,Status\_ordered

I want to check if for this transaction if the order was delivered in the next 15 mins or not,, if not then I want to raise an alert.

timeStamp1+10,transactionA,Status\_Delivered (then no problem )

but there is no status\_delivered for the transactionA is detected in next 15 min then i would like to generate an alert, either in kibana or in Elasticsearch .

please guide

You might want to look into [EQL](https://www.elastic.co/guide/en/elasticsearch/reference/7.15/eql.html). While it's mainly intended for security, I don't see why it can't be applied here as well.
