When you take the data capture, you should also check that the communications process (MFCS) is still running. If it is, you can then check what it is currently doing. To do this:
http://hostname:port/MF_KEEPALIVE
where hostname is the hostname (or IP address) from step 1 and port is the first port number from step 2.
If MFCS is working correctly, you should see a response similar to the following:
Server=ESDEMO ServerType=GKC Version=1.2.5 Status=Started
If you are running multiple communications processes, you can check each one in turn using this method. Each of the port numbers you recorded in step 2 corresponds to a communications process. Note that some of your communications processes for a given server may be disabled; they do not need to be checked.
