no agent connected - antivirus block?

[CommunityUser]

Hello,

I installed AppDynamices in two machines; one is working fine the other shown in viewer is "no agent connected". The only difference I can see is, the machine not working installed McAFree antivirus.

I'm wondering, any setting needed no like firewall, antivirus program to open specific port, app so that the connection goes through?

Thanks.

Hi John,

We understood that you have installed liteviewer on machine1 and you have installed AppServerLiteAgent on machine1 and registered fine at liteviewer at machine1 at http://machine1-host:8990/

and you have installed liteviewer and is running fine at machine2 host at http://machine2-host:8990 (default liteviewer port 8990) and the lite agent installed on server at machine2 host is failed to register at 8990 port,

If the above said is right, make sure 8990 is opened and also let us know liteviewer and liteagent are in different machine if this is the case please open the 8990 port as well. Also if the liteviwer is running in different machne say machine2 then provide the machine2 ip and port using -Dappdynamics.viewer.host= and -Dappdynamics.viewer.port= -D parameter in addition to -javaagent jvm opts in server with lite agent configured and restart the server/jvm and see how it goes.

Make sure liteviwer instance is reached from liteagent machine

We understood that you have two instances of liteviewer as we see one liteviewer instantiated using java jar adlite-viewer.jar can only monitor one lite agent.

Let us know if that information helps.

Thanks,

Hi Arun,

Thanks for the quick reply.

My case was, two machines, say M1 and M2, they both contain IBM Websphere 7; but M1 doesn't have any anti virus program running; when M2 does  - McAFree installed and running.

Now install both the viewer and agent on M1 and M2 (M1 and M2 are separated, no connection); M1 works fine - the viewer dashboard displays the Websphere; but viewer on M2 shows No Agent Connected.

It seems to me, the McAFree blocks the communication between the viewer and the agent.

My question was,

why not working on M2, how to make it work, do I need to re-config anything on the port or on the anti virus, or firewall, etc?

Thanks.

Hi John,

Thanks for the update, we do see such issues and we had overcome by unblocking firewal and also setting permissions at on the anti virus, or firewall, making sure that they are not blocking any port or http communication or the java program itself

Can you please send the aget and liteviewer logs to better assist you? we would like to go through the logs once to see if the both java process are running fine and see if any errors related to communication.

Thanks,

Arun
