How to Add Agent Connection?

CommunityUser

Hi - I just installed AppDynamics Lite on a machine with the following details:

2GB RAM, IIS 6.0, .Net Framework 3.5

I was able to launch the AppDynamic Lite Viewer but I get no agent connection.

I tried accessing the system/application that I'm trying to monitor but I am getting no response in the viewer.

The transaction is actually just to connect to the app server (i.e. loading the homepage), but when I checked the viewer I'm seeing no transaction. Does it mean that AppDynamic detects transactional queries that triggers access to-fro a Database?

I have attached the log files from the AppDynamics folder on my local drive for further reference.

Hope you can help.

Hi Karen,

I do not see any W3WP (IIS) log entries which would be expected if the app agent is loaded correctly.

This has typical can have one of this reasons:

1.) No load on the IIS, assuming that the website you host is using ASP.NET.. Also make sure to execute the aspx page you use for testing at least a few times.

2.) Did you have any other profiler or APM tool installed before? 
Can you please check if there is any other APM solution installed on the system(Microsoft Operational Manager- MoM)?. 
Please confirm the value for the following: 
1) value of "COR_PROFILER" system level environment variable. 
2) value of "COR_PROFILER" under the following registry keys if they exist (You can search for this key and let us know the value) 
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\IISADMIN 
My Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ 
My Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\ 
My Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\

 

Let us know if this helped to solve the issue.

 

Kind regards,

Theo

Hi tjungeblut

 

Thanks tjungeblut! I see, does it mean that if the page is in .htm it is not considered as transaction? :slightly_smiling_face:

 

By the way, the machine has no other APM installed.

 

Thanks,

Kars

Hi Karen,

I suppose you have followed the step mentioned by Theo. If you have issue in instrumenting application kindly set us the latest logs

FYI, please find supported Applications and Frameworks for .NET

http://litedocs.appdynamics.com/display/ADLite/Supported+Applications+and+Frameworks+for+.NET

Regarding your query "does it mean that if the page is in .htm it is not considered as transaction?", could you please brief about the application architecture, this could help us understand the issue.

Please write back to us, if there is any disconnect.

Thanks,

Santosh

Hi Everyone,

Thanks for your query responses.

I am already able to see BUSINESS transaction  connection upon accessing the .ASPX page.

However, I do have some further clarifications.

Here is the case:

- I installed the AppDynamics Lite in the WebServer where the application is hosted.

- I accessed the .ASPX homepage using the webserver machine

- Voila! I was able to see business transaction connection

- But when I try accessing the .ASPX page in a different machine/workstation, no business transaction connection is detected.

Does it mean that I have to do the transactions using the machine where the webserver resides? :slightly_smiling_face:

Thanks,

Kars

Yes Karen,

You are correct, .Net Lite can only instrument applications which are hosted in IIS. So what that means that we will capture request which are coming into IIS Hosted app (w3wp.exe) and only after execution starts with the monitored w3wp.exe.

 

Kindly let us know you have any further queries.

 

Thanks,

Santosh

Hi Karen,
 
Sorry for the miscommunication. Let me understand the case, 
-you have hosted the application in WebServer-A and on the same server    AppDynamics .Net Lite is installed and 
-you have accessed .ASPX pages from this same machine ( WebServer-A) and you are able to see Business Transactions(BT), this works as expected.
 
In other case, when you try instrumenting application hosted in WebServer-A by browsing the .ASPX pages from other machine/Server say Machine-B, as you mentioned you are not getting Business Transactions (BT), ideally this should NOT be the case, BTs should get detect irrespective from where pages are getting accessed.
 
Could you please let us know, how you are accessing pages of WebServer-A from Machine-B? (ex. http://webServer-A:9898/HomePage.aspx or http://192.120.22.44:9898/HomePage.aspx)
 
 
Thanks,
Santosh
