> The mesos agent is logging a INFO log in the agent that prints out the number of QoS corrections received from the module [1]. By default, this method gets called in a tight loop, which results in the logs getting flooded with noise.
> {code}
> mesos-slave[14591]: I0930 17:31:19.278774 14598 slave.cpp:5049] Received 0 QoS corrections
> mesos-slave[14591]: I0930 17:31:19.280088 14602 slave.cpp:5049] Received 0 QoS corrections
> mesos-slave[14591]: I0930 17:31:19.281497 14599 slave.cpp:5049] Received 0 QoS corrections
> mesos-slave[14591]: I0930 17:31:19.282856 14614 slave.cpp:5049] Received 0 QoS corrections
> {code}
> Even after reducing the QoS checking frequency, this line does not make for a good INFO log as it is periodic. Can we change it to only log when there are non zero number of corrections received from the module? I can send a patch if this is acceptable.
