Hi,  
In metrics, I want to add a filter  
"myhost" like "^localhost.\*$"  
I have a scroll list with: is, is not, is one of, ... butno is like  
I try with Query DSL but it is not working, surely dur to a bad syntax  
Is it possible, how to process ?  
thanks for your tips,

Hello,  
Are you trying to filter for all hosts that start with "localhost" ?  
If so, you can add this in the search bar: `myhost:localhost*`  
And if you want to do it from the filter bar you can set it to `is` and then add the wildcard to the string in the text box: `localhost*`
