Our friends at Microsoft have helped us information architects out with some official Visio shapes for SharePoint. IT Pros and Farm Admins certainly will benefit as well.
Creating visual representations of your Microsoft Office and Office 365 architectures, including Microsoft Exchange, SharePoint, and Skype for Business is a helpful way to communicate your deployment. These Visio stencils provide more than 300 icons -- many depicting servers, server roles, services and applications -- that you can use in architecture diagrams, charts, and posters. These icons are primarily centered around deployments of Microsoft Exchange Server 2013, Microsoft Skype for Business, and Microsoft SharePoint Server 2013 as well as hybrid Office 365 deployments of aforementioned technologies.
The zip file now includes both stencil sets from 2012 and 2014.
The go-to tool for trapsing through SharePoint's ULS logs has always been ULS Viewer, attributed to Daniel Winter (Blog | Twitter) at Microsoft. However, obtaining this tool has recently become a problem because https://code.msdn.microsoft.com/ULSViewer no longer brings you to a place you can download it.
I am glad, in this case, that I am slightly OCD and save all of my downoadable installers in an organized manner and back them up. Thus, I can make avaiable the latest copy of ULS Viewer that was available (version 2.0.3530.27850 10/09/2009), as far as I know. According to the license that accompanied the download and applied to the MSDN Archive Gallery, this is legal for me to distribute here. These are the original unaltered files with modification dates from 2012 when I downloaded them.
The ZIP archive contains the two original files--a Word document describing the tool, and the executable file.
A good overview of the tool is avaiable in this article or this blog post. There are, of course, other log viewer tools for SharePoint that are out there. I encourage you to try them out to see which one works best for you.
