AppDynamics not detecting standalone windows service

CommunityUser — Thu, 08 Feb 2018 19:20:57 GMT

I am trying to register a standalone windows service as a separate tier / node to AppDynamics. So far in my dashboard it appears that the IIS services were detected, but the standalone has not.

I have confirmed that the standalone displays when running tasklist /m mscor*, and I have also restarted the coordinator service and standalone after updating the config.xml file.

Strangely, although the IIS services show in the controller dashboard, on using the Agent Configuration tool, I keep getting a 403 forbidden error when trying to test controller connection.

Are there steps I am missing? Do I need to put load on the standalone for it to be detected?

Hi there,

The load could be the issue, have you tried that?

I did find this other thread that might help (with associated KB): https://community.appdynamics.com/t5/NET-Agent-Installation/Windows-service-is-not-showing-in/td-p/27194

What exactly counts as load for a windows service? I have tried running the service several times as well as sending a message using it every couple of seconds, but it does not seem to register in the controller UI. Actually, the tier does not show up at all in the Tiers & Nodes tab.

Hi,

Could you please post the section from your controller-info.xml where you configure the standalone services? (please mask any sensitive information) or maybe you tried configuring using the configuration utility as documented here, https://docs.appdynamics.com/display/PRO44/Configure+the+.NET+Agent+for+Windows+Services+and+Standalone+Applications

Standalone services are not detected by default and you have to configure them.

Thanks

Gurmit.

By controller-info.xml, do you mean the config.xml file?

I've included these lines:

<app-agents>
    <IIS>
      <automatic />
    </IIS>
    <standalone-applications>
      <standalone-application executable="MyService.exe">
         <tier name="Windows Service" />
      </standalone-application>
	  
	  <standalone-application executable="E:\Program Files (x86)\...\MyService.exe">
         <tier name="Standalone Tier 2" />
      </standalone-application>
   </standalone-applications>
</app-agents

I have already tried using the configuration utility, but for some reason I kept getting a 403 forbidden error when trying to establish connection with the controller. Strangely, the IIS services are detected in the controller UI despite this.

Config looks good.

For how much time does the standalone service/exe run continously? Does it run for more than 2 or 3 minutes at a stretch?

If not, can you run a multiple times within a given minute and run for a few minutes?

Re: Connection refused error from the configuration utility does not make sense since IIS is already reported.

The standalone does not run continuously, but the Windows Service should be running continously, yet it is not registered in the controller either. I tried putting some load on it, with the process memory usage increasing around 20 mb, but nothing seems to be reflected in the controller.

One additional note, although I have defined the Windows Service and Standalone tiers in my config file, I do not see them listed as tiers in the Tiers & Nodes tab. Does this mean that the controller may not have received the updated config file?

For Windows Service also, you have to give the full path to the exe in your config file.

Also, i assume for the standalone service, you have masked the path when you copied it here but have the full actual path in your configuration?

If the same server is reporting for IIS, then you wont see the tier getting registered without any traffic being detected.

I changed the Windows Service executable to the full path. I still can't seem to connect to the controller.

In AgentLog.txt, I am getting this error on searching for the windows service:

Could not connect to the controller/invalid response from controller, cannot get initialization information, controller host [...], port[80..], exception [System.Net.WebException: The remote server returned an error: (403) Forbidden.

Are you sure your IIS sites are still reporting and collecting data? and its from the same server?

I would fix that issue first (connectivity) before checking the standalone services.

I currently see 2 databases and 5 nodes in my Controller UI, and there is a change in the number of calls between the last hour and the last 2 hours, so I believe that the IIS services are still reporting data.

I can access the Controller through Chrome and I am also able to reach it through telnet, but I still cannot with the Configuration Utility.

I was able to successfully connect my Standalone Application and Windows Service to the Controller. I'm still not entirely sure what the cause of the connectivity problems was, but I was able to get around it by filling in the Controller domain and port into the proxy options in the configuration.

Thank you for your help!

Are the nodes and IIS that are reporting on the same server as the one on
which standalone service runs?

Thanks,
Gurmit.

Yes, they are hosted on the same server (Windows Server 2012 R2).

I believe I may be experiencing a similar issue and 1 of the warning in my agentLog specifically talks to an issue around a proxy.

Can you perhaps share how exactly you added the controler host and port into the proxy section?

Re: AppDynamics not detecting standalone windows service

CommunityUser — Fri, 09 Mar 2018 10:43:14 GMT

Hi There

Also added the controller info as a proxy tag and the app server agent is now showing on the dashboard as up.

Thanks for the tip.

Its not the controller host and port that go in the proxy section but the proxy host and port if the connect needs to be made via proxy.

The following link should be helpful (Step 2)

I faced a similar issue recently. I think the problem is a bug in Extension Manager because it doesnt work well when need to connect via proxy without authentication. If you use proxy with authentication it works fine but when use proxy without authentication it throws the 401 error.
