Graylog plugin to go back to the past, check the alert for a specified time and alert in the present

Required Graylog version: 2.3 and later

Installation

Restart graylog-server and you are done.

Usage

Function Prototype:

First we have to select the alert type Delorean

Then we have to set all the common fields plus query, backtime and the staytime. You must complete the query field with a normal query, the same that you do in the search field in the graylog search mode, for example field:"value".

All set! We now can go back search an event for sometime in the past and get the alert! This is usefull when the log have some delay and it's timestamp isn't the same as the EventReceivedTime when the log arrives.

Also you can use this feature to not just search for a 1 minute time event, all you have to do is set the backtime in 0.
