Hello Members,

We are building Dynatrace from scratch for a customer and we want to apply & use a Tag to create SNOW incident based on hostname (eg. of a host: [hostname.domain.customer.com](http://hostname.domain.customer.com)). Basically, we want to use detected host name as an auto-tag in upper case and for same, I created an automatic tag with following configuration with tag name “HOST” but all I can see on hosts an auto tag called HOST and nothing in its value. Please guide what I am missing here.

Hi,

Can you remove space between “/” and “(”. Just for try it.

Best regards

Thanks&nbsp;[@AntonPineiro](https://community.dynatrace.com/user/58682)&nbsp;. It worked, silly mistake to leave whitespace.
