Troubleshooting Appdynamics Agent Install on Windows ECS Fargate .Net Framework IIS application

[Rupert_Broad]

I'm trying to get the App Agent running on a Windows ECS Fargate container. Agent installs and connects to the coordinator and registers the machine agent but the App Agent and CLR are not discovered/registered. On a regular Windows Server instance doing 'iisreset' usually resolves this issue. In the container startup script there is an iisreset but it's obviously not working.

I get the same result if I build/run the container locally on a Windows Server, so Fargate is not the issue.

config.xml

<?xml version="1.0" encoding="utf-8"?>
<appdynamics-agent xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <controller host="AppDynamicsAppHostName" port="443" ssl="true" enable_tls12="true">
    <application name="AppDynamicsAppName" />
      <account name="AppDynamicsAppAccountName" password="AppDynamicsAppAccountPassword" />
  </controller>
  <machine-agent />
  <app-agents>
    <IIS>
      <applications>
        <application path="/" site="api">
          <tier name="AppDynamicsTierName" />
        </application>
      </applications>
    </IIS>
  </app-agents>
</appdynamics-agent>

When the container registers with the coordinator, it does NOT assign the agent to the Application Tier. 

As far as I can tell from logging, there are no errors or issues during install or when container starts.

What I don't understand and what isn't discussed in the documents is how AppDynamics determines whether the App agent is installed and where I need to check (logs/xml/config) to find any misconfiguration.

Hi @Shane.Tembo,

Since it's been a few days with no reply from the community, did you happen to find a solution or anything you can share?

If you still need help, you can reach out to Cisco AppDynamics Support: How do I submit a Support ticket? An FAQ 

[Shane_Tembo2]

Hi @Rupert.Broad ,

Do you perhaps have some steps i could follow to install the .Net and Machine agents on fargate containers?

Im having a tough time finding the correct steps to follow and I need to get this done.

Thanks in advance.
Shane.

Hi @Rupert.Broad,

Thanks for experimenting and reporting back. I'm trying to get someone to look at this conversation and see if anything isn't working as expected. 

[iamryan]

Hi @Rupert.Broad,

Just confirming, that despite it being slower than expected, everything is working as expected?

[Rupert_Broad · Accepted solution]

@Ryan.Paredezyes waiting 36 hours seems to do it. As this really isn't acceptable in any production environment and did some more testing and rearranged the container image build and now have appdynamics installing at runtime not during image build. This works as expected - new container is registered as soon as the agent is installed.

[Rupert_Broad]

After 36 hours the App agent decided to do whatever it needs to do to register with the App Tier and start forwarding useful information to AppD. Not particularly useful in a container environment but it's windows - everything's a bit slower

Hi @Rupert.Broad,

I've heard back. 

"The command line has installer log location specified
msiexec /i dotNetAgentSetup64.msi /q /norestart /lv %TEMP%AgentInstaller.log AD_SetupFile=<absolute path to setup config.xml> meaning that 
MSI engine (owned by Microsoft) will decide if the agent is already installed, and will quit after logging the error. MSI looks at the registry to figure if that MSI is already installed."

The Unattended Installation section goes over this, but just in case step 2 was edited to say that you can use that command for troubleshooting https://docs.appdynamics.com/appd/22.x/latest/en/application-monitoring/install-app-server-agents/ne...

Hi Ryan,

Sorry, my bad - I wasn't sufficiently clear. The AgentInstaller.log shows the machine agent is installed successfully

MSI (s) (6C:EC) [21:37:31:896]: Product: AppDynamics .NET Agent -- Installation completed successfully.

MSI (s) (6C:EC) [21:37:31:897]: Windows Installer installed the product. Product Name: AppDynamics .NET Agent. Product Version: 22.10.0. Product Language: 103
3. Manufacturer: AppDynamics. Installation success or error status: 0.

and if I look at the agentLog.txt I can see that the machine agent registers successfully with the coordinator and picks up the correct info from config.xml

But there's no mention of the App Agent or CLR and the agent doesn't get registered to the Tier in the UI.

Hi @Rupert.Broad,

Thanks for sharing. I have shared this with the Docs team. I will report back here when I hear something. It may not be a super fast turn around just to set some expectations. 

If you happen to find a solution or workaround on your own in the meantime, please do share that here as well.

Hi @Rupert.Broad,
