APM 9.5.x Java Agent: how does it get the machine name

[Pat O'Connor]

Hello,

In regards to the Java agent or any other agent that attaches to the Enterprise Manager, how does the agent get the "Host Machine" name? Does the agent at startup on a server get the hostname from /etc/hosts, DNS, etc?

 

Regards,

The agent uses the Java getHostName() API.  EM does the same thing.

Hello,

Interesting, so when the java agent starts on a server it uses that "Java getHostName() API" to discover the server host name, can you tell me on where to find this line of code?

 

thanks for your input,

Pat

Hi here is a link to the API.

 

InetAddress (Java Platform SE 7 )

Hi Pat:

Autonaming is discussed at length in Java Agent Naming - CA Application Performance Management - 10.3 - CA Technologies Documentation

 

Do you have any followup questions or did you get the answers that you were seeking? Please let us know.

 

Thanks.

Actually, according to his screenshot, domain1 would fall under the autonaming convention.  qw32vtest01 is his hostname and the one he's asking on how we determine what it is.

 

But still a good read on the autonaming though.
