turn on logging in qpid c++ client

[Todd Herman]

I have a service that I wrote in C#.  It is using the dotnet binding for the c++ qpid client.  I have logging in my application that logs what is going on.  Ion the conneciton object, I have turned on AutoReconnect.  When my code tries to connect but can't, my code appears to hang.  The issue is that the connection is trying to reconnect but I have no indication of this because I don't seem to have a way to be notified of this if AutoReconnect is on.

Previously my code was not a service but just a console application.  When it ran that way I actuall saw log messages written to the console that were coming from the qpid library itself.  I didn't do anything to turn those on.  I am not sure why I can't see those messages now but I need to either see those internal log messages or have some way to know that the conenction failed and is being retried.

You can configure the logging with the QPID_LOG_ENABLE environment
variable. E.g. export QPID_LOG_ENABLE=info+

I am using Windows and don't know what "export" is.  I did, however, already setup the log enable environment variable and that didn't seem to do anything.  Does anyone have any other suggestions?

For windows it would be:

set QPID_LOG_ENABLE="info+"

See, as an example, the file qpid-server.bat in the distribution source.

Oops, sorry! I missed the obvious there :-)

Since you are running as a service, the console output may be lost. You
could also define a value for QPID_LOG_TO_FILE, to have the log go to a
specific file.
