Graylog Alert set_field to true or false if message in time range

Graylog Central (peer support)

I’m trying to create an alert that only sends if messages are received between 2:00PM and 6:30PM.
I’ve created this rule (some of my syntax might be incorrect, can ignore)

rule “function is_trading”
when
has_field(“timestamp”)
then
let msgTime = to_string($message.timestamp.hourOfDay) + “:” + to_string($message.timestamp.minuteOfHour)
set_field(“trading_hours”, to_string(“14:00” <= msgTime < “18:30”))
end

Any thoughts on how to accomplish this would be much appreciated.

Hello and Welcome,

I think this might be what your looking for.
I use this for users that login at a certain time. You probably can adjust it to fit your needs.

Hope that helps.
