OpenStack is made up of various services. These services have their own logs stored under /var/log directory.

While the tail command is the most popular, there are many benefits of using web browser to view the logs. In this blog let us see how we can view OpenStack Controller Logs using a browser.

PyCharm and OpenStack programming

In this blog, I will show you how to use the PyCharm IDE from Jetbrains for your OpenStack programming. I will use the Neutron ML2 driver code from my book OpenStack Networking Cookbook to guide you in setting up the PyCharm IDE.

Announcing: OpenStack Networking Cookbook

My first publication OpenStack Networking Cookbook is now available for purchase. It is available as a printed book as well as e-book. OpenStack is a rapidly evolving cloud platform and Networking (Neutron) is one of its critical components. The current trends of SDN and NFV make OpenStack Networking even more exciting and complex. I have co-authored the book with a colleague and the overall experience of writing a book was very satisfying.

Ports in OpenStack Neutron

Sriram S

OpenStack supports rich abstractions to handle virtual networking needs in a cloud. As a user the most visible entities are the Network, Subnets, Routers, Firewall etc. But if we consider ingress and egress points for data traffic, the most critical entity is the Port. OpenStack Neutron Ports are usually created automatically as part of other user operations. However the CLI allows users to create Ports independently as well.
