Need to extract aws-region from host name

[smaran06]

Hi Team,

I want to extract aws-region from host name. 

host= "my-service-name-.ip-101-99-126-252-us-west-2c".

I want to extract us-west-2 from the host. How I can achieve this.

@smaran06 Try using the below command:

| rex field=host "\.\w+.\d+.\d+.\d+.\d+.(?P<aws_region>.*)"
