There are the steps i have taken so far:- 1)created a image template from a vm 2) spin new vms from that image 3) each vm (and the image) had logstash forwarder running on it

Now the issue is when i check in logstash all messages are coming under the same hostname of the image-vm.

Say I created the image from vm whose hostname is "test" All new vms (even though they have a different hostname) are sending messages with host="test"

any pointers ? where i need to fix the hostname so that image-hostname is wiped by currect hostname ?

Is it possible to use the host ip on the logstash forwarder instead of the hostname? What does your json config look like?

I am not actually setting the host explicitly for logstash anywhere but i would certainly need hostnames. I am not sure from where logstah picks up the hosts. The log message has a hostname which is correct since i set it explicitly

As you can see below "nj-test9-19" is the correct name but logstash thinks its coming from host "nj-test-3.novalocal"
