hello i need help i am new  
I'm trying to add a threshold to the topbeat logstash filter, I want to add a message to tags but do not add it to me  
This is the filter I have:

filter {  
if "topbeat" in [tags]{  
if [{mem}{used} \> 1] {  
mutate {  
add\_tag =\> ["memory\_full"]  
}  
}  
}  
}

Topbeat has been deprecated and you should really upgrade to metricbeat.

Also I don't believe that the field reference `{mem}{used}` is valid, see [https://www.elastic.co/guide/en/logstash/6.2/event-dependent-configuration.html](https://www.elastic.co/guide/en/logstash/6.2/event-dependent-configuration.html)
