On the second ever Webcast Friday that InterWorks has produced, I had the honor of speaking to our web audience about Tableau Server performance monitoring. In this talk, I wanted to highlight what a server does for us, what makes a server run slowly, what...
Tableau purchased Power Tools in 2019. Contact Us for more information. I had the opportunity to join InterWorks at the beginning of 2014 and play a key role in the launch of a brand new toolset called Power Tools for Tableau. At that point in time,...
There's much to be thankful for in November, namely some new content! We wrapped up another epic Tableau Conference and had plenty of coverage on the blog. Additionally, we saw an interesting mix of deep dives, videos and an excellent podcast. Between the conference and Thanksgiving, we...
Here's a feature that's been unofficially around for a while on Tableau Server, but is now supported on Tableau Server 10. We've all got Tableau Servers that look like this. Lots of projects which we have access to, and all pretty boring looking. Wouldn't you...
With the imminent arrival of Tableau 10, I thought that it's time to take a quick look at all the new features and functionality that will be made available with Tableau Server 10. Minimum Requirements Firstly, let's look at the minimum requirements. There is no longer a 32-bit...
Tableau in the Cloud Tableau and Google already form a potent mix, as Tableau supports a number of Google's data sources with native connectors, such as Google BigQuery, Google Analytics and Google Cloud SQL. But as of last month, Tableau Server is certified for use on...
Are you a Tableau Desktop user who is new to Tableau Server? Do you find yourself confounded by all of the thingamajigs and whatsits, and just want someone to tell you what you need to focus on? If so, then you want this post. In this...
Tableau Server installs with a handy command-line utility for scripting common site administration tasks called tabcmd. To get the installer for this utility, the Tableau Server admin guide points you to the extras folder in your Tableau Server installation directory, e.g. C:Program FilesTableauTableau Server9.3extrasTabcmdInstaller.exe. While Tableau hosts these installer...
It’s 2003, and the Red Sox haven’t been to the World Series since 1986 and haven’t won a World Series since 1918. Here, at this moment, in the 8th inning of Game 7 of the American League Championship Game against the hated New York Yankees, a...
Our client needed to provide external users (their customers) with access to their Tableau Server on Amazon Web Services (AWS). When it came time to discuss authentication, Active Directory (AD), while generally a good choice within an enterprise, was quickly ruled out. They needed an identity/authentication...
Here’s the second item under Local Computations: "Table calculations are powerful, but they can be slow. They are dependent on the local computation engine and can require substantial memory." Let’s get started. Table Calculations Table calculations are computations that use the values in the entire table and can restructure...
Here’s the first guideline from the Local Computations category: "Even if a workbook is published to Tableau Server, local computations still impact performance. Leverage the power of Tableau Server whenever possible by limiting local computations such as groups, hierarchies, reference lines, table calculations and blending." Let’s get...
Who doesn’t love efficiency? We are finishing up with the rendering category today by returning to custom shapes. Let’s get started: "If using custom shapes, use transparent background PNGs instead of JPGs. Views will render cleaner, and shape files will take up less space." Didn’t know we’d get...
Let’s take a look at our next guideline from the Rendering category: "Minimize the file size of any images or custom shapes where possible. As a general rule of thumb, keep images under 50kb." Let’s get started, shall we? Images & Custom Shapes In regards to rendering, images and...
Let’s take a look at the next item on our rending category. "Limit the use of detailed text tables with lots of marks." Ah yes, the fabled Text Table. Mark Counts Let’s start this discussion by reviewing mark counts. We covered this in the previous Rendering article in the...
Today, I ran into a Tableau issue that I couldn't solve through googling. Using SAML and attempting to connect to Tableau Server from Tableau Desktop, I wasn't given the option to enter a username and password. Instead, I received this message containing "errorCode=16:" Here's What Happened I was...
The first item in the Rendering category is: "Avoid high mark counts. More marks = longer rendering time." Let’s jump right in on this one. Mark Counts Marks are the points, plots or symbols on your visualization. They can be the bars in your horizontal bar graph or the...
Here’s the next item on the Performance Checklist: "Avoid row-level calculations involving parameters." Let's first take a look at what row-level calculations are. Row-Level Calculations Row-level calculations, also known as record-level calculations, operate on every record in the underlying data. An example of a row-level calculation is an IF...
If you embed your Tableau analytics dashboards through either a straight embedded i-frame or with the JavaScript API, upgrading your Tableau Server to 9.1 will cause some unexpected grief. But it’s fixable. After upgrading Tableau Server to 9.1, I was getting this error: Refused to display 'https://path/to/my/tableau/dashboard?:embed=y&:showVizHome=n&:tabs=n&:to...
I've had the pleasure of working with a large number of Tableau Server users and administrators, and by far the most common phrase I hear is "What the [expletive redacted] is up with permissions?!" Permissions in Tableau Server are very simple, given two conditions: Forget everything you...
