You could fully restart the host as well, but it is only necessary to do so for the processes required.</P> Thu, 21 Sep 2017 18:09:09 GMT hayden_miedema 2017-09-21T18:09:09Z Change of hostname https://community.dynatrace.com/t5/Open-Q-A/Change-of-hostname/m-p/36203#M1306 <P>If a hostname gets changed on the command line of a host that already has an agent does that change get shown on the details of the host in the Topology? We have an example of a host (with agent) getting cloned to a different IP address and then the name being changed on the command line. The original name and new IP continues in the Host details.</P> Tue, 30 Aug 2022 11:01:40 GMT https://community.dynatrace.com/t5/Open-Q-A/Change-of-hostname/m-p/36203#M1306 rb0c70091 2022-08-30T11:01:40Z Re: Change of hostname https://community.dynatrace.com/t5/Open-Q-A/Change-of-hostname/m-p/36204#M1307 <P>This would require a restart of the desired process to which you wish to see changes since the agent is already injected at the time the change is made.

So are you saying that the "discoveredName" in the Host Topology API will change if I restart the host after changing the hostname ?</P> Fri, 22 Sep 2017 06:46:04 GMT https://community.dynatrace.com/t5/Open-Q-A/Change-of-hostname/m-p/36205#M1308 rb0c70091 2017-09-22T06:46:04Z Re: Change of hostname https://community.dynatrace.com/t5/Open-Q-A/Change-of-hostname/m-p/36206#M1309 <P>Hi Ray,</P><P>Yes that's right. It should change after a restart.</P> Fri, 22 Sep 2017 16:39:05 GMT https://community.dynatrace.com/t5/Open-Q-A/Change-of-hostname/m-p/36206#M1309 hayden_miedema 2017-09-22T16:39:05Z
