A Windows Azure hosted service may comprise multiple instances of multiple roles. These instances all run in a remote Windows Azure data center—typically 24*7. The ability to monitor these instances non-intrusively is essential both in detecting failure and in capacity planning. This article by Neil Mackenzie, author of Microsoft Windows Azure Development Cookbook, shows how Windows Azure Diagnostics provides for the non-intrusive capture of diagnostic data and its subsequent persistence to the Windows Azure Storage Service. Windows Azure Diagnostics supports various standard sources, allowing for their extensibility where appropriate. The topics covered in this article include:
- Using the Windows Azure Diagnostics trace listener
- Performing an on-demand transfer
- Implementing custom logging
- Accessing data persisted to Windows Azure Storage
- Using the Windows Azure Platform
- PowerShell cmdlets to configure Windows Azure Diagnostics

Since Ethan Marcotte coined the term "responsive web design", people have been looking for the best way to do it, which has cumulated into the Goldilocks approach versus the Fluid approach, and Desktop-first versus Mobile-first. The only right answer is to do what you're most comfortable with and, as always, avoid dogma. In this section we'll go over the differences between each approach and even sample them so your RWD tool belt is well equipped.Read Different strategies to make responsive websites in full
In this article by Michael Badger, we will go through the process of discovering and modeling devices to build an inventory of the network.
We'll start this article by fine tuning our device inventory through manually adding devices to our inventory. Then we'll take a look at the main device status view and perform some routine device administration tasks. The second half of the article demonstrates the available monitoring protocols that Zenoss uses to model the devices.
We'll continue to demonstrate features using the Mill Race network, but feel free to substitute your own devices in the examples given in this article. By the time we finish this article, we'll have a detailed model of our networks.Read Device Management in Zenoss Core Network and System Monitoring: Part 1 in full
The primary focus of Pluggable Authentication Module (PAM) is to authenticate your users. PAM lets you set up the environment that the users will work in. And when the users log out, PAM tears down the working environment in a controlled way. PAM and PAM-aware applications reduce the complexity of authentication. Application programmers can take advantage of PAM, rather than developing a complete set of authentication functions. In this article by Kenneth Geisshirt, we will see how an application uses PAM for authentication and how to develop our own PAM modules.Read Development with Pluggable Authentication Modules (PAM) in full
