Troubleshooting Agent Registration Issues ? "Encountered error during registration"

CommunityUser — Sat, 22 Apr 2017 15:51:08 GMT

There seems to be very little information on the Internet or Appdynamics documentation on troubleshooting agent registration issues.

I'm trying to register a new server agent on Linux with Appdynamics I get a very obscure registration error when running the agent:

---

The agent I'm using was generated from the Appdynamics enterprise dashboard and uploaded to the linux server.

Things I've checked:

- Network connectivity: packet flow at tcp level is fine between agent and server.

- Licensing: Licensing is valid

- hostname/unique agent id: as a test , set manually using the result of "hostname" command.

There seem to be no other appdynamics guides on how to troubleshoot this in further detail. Past forum posts seem to yield low quality answers.

More complete debug log dump as follows:

Troubleshooting notes:

Trying to register a new agent with the controller fails, even though I am using a superuser account to generate the agent zip file and I have more than 50 agent licenses (i've also disabled SIM on the agent side):

Logs on the agent show:

NOTE: registration also fails if SSL is turned off and non-https port is used to connect to the controller.

Additional data point, in the controller logs I see these entries, suggesting some kind of authentication error between agent and controller:

However, this agent was built through the UI and there is no indication of a user or credentials that may be needed ..

Dear Traiano

Sorry for the poor experience you had with that forum. If you are a paid customer and want to drive this through support, you can use the AppDynamics portal to log a ticket.

However, i may have an idea for your problem. Just a confirmation: is that 4.3?

If yes, on 4.3, when generating the Machine Agent using the Getting Started Wizard, the account name used is the Global Account Name, instead of the Account Name. So you need to change that in the controller-info.xml file.

Let us know

Best

Hi JB

Thanks for your response.

We're using a licensed version of AppDynamics Version 4.3.0.3, build 147.

I've confirmed we're using the global account name in controller-info.xml.

I've also confirmed we're using the corresponding license key.

However the issue persists. How would I troubleshoot this issue further?

Thanks in advance,

Traiano

Any response yet? Surely this can't be a difficult issue to resolve?

Re: Troubleshooting Agent Registration Issues ? "Encountered error during registration"

Jean-Baptiste_M — Mon, 24 Apr 2017 07:18:13 GMT

You said : (i've also disabled SIM on the agent side): meaning the SIM enabled is set to false in the controller-info.xml right?

What's your controller version?

Have you checked the license screen? Have you reached any limit in term of license tokens?

If you want to get proper attention, maybe you should open a ticket to our support on the portal.

Re: Troubleshooting Agent Registration Issues ? "Encountered error during registration"

CommunityUser — Tue, 25 Apr 2017 07:00:20 GMT

Correct. Here is the specific line: <sim-enabled>false</sim-enabled>

As mentioned before, version is: AppDynamics Version 4.3.0.3, build 147

Attached screenshot of licensing output.

If it's necessary to run this through support, ok, I'll do that. I thought community support would be sufficient to resolve this kind of problem.

thanks,

Traiano

... Sorry I've just connected the dot..

You need to just put the account name, not the global account name in the controller-info.xml file. There's a recent identified bug on this.

Let me know

Thanks for the response!

I know how to find the global account name, but where exactly do I find the "account name"? (apologies, appdynamics newbie here!)

Thanks in advance,

Traiano

Ok, this seems to work. There are other issues now, but I'll report them through the support portal.

Click on the wheel on the right upper corner, then licenses you should see
the name there.
Take me a screenshot I can tell you
