What does the entry "FAIL: Unable to initialise MQ libraries." in the netprobe log file indicate?

It means that the Netprobe was not able to locate the MQ library files

The MQ library files for UNIX platform are;

libmqm.so for binding mode configuration

libmqic.so for client connection mode, for UNIX system.

These libraries must be added to the variable LD_LIBRARY_PATH

For Windows, the files are;

mqm.dll for binding mode configuration

mqic32.dll for client connection mode

These libraries must be added to the variable PATH
