We need to let customers know that since OSP15 the sensu-client is being deprecated and is going to be removed in OSP16.
I can see that fix that introduced in sensu.pp,rabbitmq.pp and uchiwa.pp is included in puppet-tripleo but I can't find any messages related sensu deprecation in /var/log/message or in an sensu logs
