I want to monitor only limited number of mount points using metric beat. How do I filter out the rest?

I did come across a filter -

> filters:  
> - drop\_event.when.regexp.mount\_point: '^/(sys|cgroup|proc|dev|etc|host)($|/)'

Is this the only option around? This is for exclusion but not inclusion(which I require). This can be tweaked to somewhat serve my purpose but if only I do not get anything.

> - drop\_event.when.regexp.mount\_point: ^((?!(/opt/apache|/opt/avamar/6)).)\*$'

Probably you can use `not` condition here, take a look to [https://www.elastic.co/guide/en/beats/filebeat/current/configuration-processors.html#condition-not](https://www.elastic.co/guide/en/beats/filebeat/current/configuration-processors.html#condition-not)

Thank you so much @exekias.  
This worked for me.

Below is a working sample -

> mount\_point: "/"  
> - not:

> mount\_point: "/boot"  
> - not:  
> equals:  
> mount\_point: "/home"  
> - not:  
> equals:  
> mount\_point: "/images"
