Arming OpenStack monitoring

There are several ways to keep an eye on and watch what is going on in your OpenStack private cloud. We have already discovered the expanding Telemetry module as an official monitoring service well integrated into OpenStack. It might be a very fruitful solution to facilitate customer billing as well. Although the former Telemetry module is expanding its metrics to cover the image, compute, block and object storage, and network service, it might be needed to bring more mature infrastructure monitoring tools for additional alerting. When dealing with large private cloud infrastructure, more hardware and virtual resources are added to the monitoring inventory list and keeping a close eye on any possible abnormal service activity is not an easy task. Dealing with such a challenge, an OpenStack operator should put in place a very sophisticated and complementary monitoring solution that covers...
