Dynatrace tagging seems not working with GCP PAAS service which we use it for our application. I did some research in dynatrace forum and found that we can tag using GCP instance name and ID but in our case, after every deployment GCP instance ID and Name gets change along with host name and i am unable to figure out what need to be done to make the tagging work even after hostname, GCP ID and Name change.
My suggestion in such cases is checking all properties that dynatrace detected for this service. In most cases there are hidden some options for tagging. You should remember as well that if there is in any property some pattern that can be matched via RegEx, this may be option for you as well. In such cases, changing name isn’t issue.
