Hi,
I am not following how to set up a machine agent.
I log into the AppDynamics console and click on "Servers" - the message that I don't have any servers appears.
I select "Get Started", select Linux from the drop-down, leaving the default controller URL, and I download the agent. I secure copy (SCP) the zip file to our Amazon EC2 server.
I create a subdirectory in /home/ec2-user called machine-agent, and unzip ~/machineagent-bundle-64bit-linux-4.5.9.2096.zip into it.
In that directory, I run:
jre/bin/java -jar machineagent.jar
which produces the following output:
(dev)[ec2-user@our-server machine-agent]$ jre/bin/java -jar machineagent.jar Using Java Version [1.8.0_162] for Agent Using Agent Version [Machine Agent v4.5.9.2096 GA compatible with 4.4.1.0 Build Date 2019-03-19 19:13:12] [INFO] Agent logging directory set to: [/home/ec2-user/machine-agent] ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console
and click "Continue" back on the servers page where I downloaded the zip file.
I tried passing
-Dappdynamics.agent.log4j2.disabled=true
to the java command, but the log4j2 error still persists.
No further output is generated by the machine agent. It just sits there. On the page that has the list of servers, the server shows up, but nothing is reported for disk space, CPU %, memory %, - all fields are blank. At the bottom of the page it says "None of these Servers have Server Visibility Enabled" - but from what I have read from other thread posts, there should still be basic information about the server showing up in the dashboard.
I click on settings, "App Dynamics Agents", and the "Machine Agents" tab, the machine agent shows up and is listed as enabled. Double-clicking on this row shows:
Name ourhostname.ourdomain IP Address ourhostname.ourdomain OS Linux Status INITIALIZING Install Time 05/22/19 6:57 PM Last Start Time 05/22/19 7:14 PM
The status never changes from initializing.
Under the Applications column, it says: "(not associated with any applications)", but when I click "Enable" and move our application to "Selected Applications (1)", and press OK, nothing changes. The row remains as "(not associated with any applications)".
Are there incoming ports that have to be opened up to allow access to the machine agent? If so, wouldn't that defeat the purpose of having an agent running on the server itself?

Any suggestions?
Someone recommended trying machine agent version 4.4 - how do you download that? From the Getting Started page, I don't see any option to download a previous version.
