    Hi, We have an APM setup with only one EM Server. We are quite concern when the APM Agent lost connection to the EM server. These are some of the questions:

    How the agent behaves when it is not able to connect to the management server ?

    How frequent is the attempt to establish the connection ? Is there any timeout period ?

    The agent will continue to collect data and store locally ?

    Once the management server is up, all the data at the managed server will be sent to the management server ?

    If yes, any throttling to not impact the network performance ?

    How the agent behaves when it is not able to connect to the management server ?

     

    ð  It will try to re-establish the connection forever.

     

    How frequent is the attempt to establish the connection ? Is there any timeout period ?

     

    ð  Initially every 15 seconds, then every 2 minutes. There is no timeout, it will keep trying endlessly.

     

    The agent will continue to collect data and store locally ?

     

    ð  No, the Agent has no local storage.

     

    Once the management server is up, all the data at the managed server will be sent to the management server ?

     

    ð  While the server is unreachable, the data is lost. When a connection is re-established, the Agent will resume its normal operation and send the “new” data.
