I'm trying to generate a simple piechart as a Visualisation in Kibana with some custom Filters, which is nothing but a hostname where the request been hit.
The current visualisation works for me but the worry factor is the filters which I added in the split slices may gets change anytime , so the current 3 filters (combination of character & numbers) gets change anytime and my visualisation may get broken or shows incorrect result. Please see attached image for more detail.
So, basically, what I'm looking is can i add filters in term of regex (never used regex to an extent) instead of hard coding the values. The value/string of the filters is always be a combination of numbers & characters with 11 characters.
