Datapower connection to APM keeps losing connection to collectors

[Daniel Addo]

My datapower connection to APM is not stable. I don't know why but it appears to be connecting to EM which is running but the log on the datapower application shows EM down.

[Haruhiko Davis]

How are you connecting DP to APM?

[Daniel Addo]

I am connecting using Datapower agent version 2 where it gets the java framework from DataPower agent. See below

Here is the error message:

Here is a command to verify if ports are opened between data power server and the EM collector

 

[esmmon@datapowerserver logs]$ netstat -an | grep 11304
