The step from 4.x to 5.0 indicates this is a major release.
Very much so in fact. The main focus of the new version is on reload alerts. Rich email alerts were introduced in Butler 4.2, but that was really just the testing ground for what’s now available in 5.0.
Here’s the short version of what’s new:
Alerts for failed or aborted reloads can be sent to Slack, MS Teams, outgoing webhooks, MQTT or as email.
Alerts sent as email, Slack and MS Teams can all make use of all the rich formatting and layout options available on those platforms.
Alert emails can be sent to the owner of the Sense app that failed reloading.
A new API for doing partial (and full) app reloads was added. This means it’s now possible and even easy to do partial app reloads in Qlik Sense. One of the epic QlikView features finally become usable in Qlik Sense!
Curious what the alerts look like in reality? Check out this video for a hands-on demo:
What’s Traefik and how does it relate to Qlik Sense?
Traefik is one of today’s most hyped reverse proxies. It’s available in both a commercial and a (very capable!) open source version. According to the company behind Traefik it’s been downloaded more than 2 billion times – that’s a lot…
In this blog post we’ll take a look at how Traefik can run natively on Windows server, providing services to a Qlik Sense Enterprise on Windows cluster. We will see how this can make Qlik Sense easier to use for end users as well as easier to run and operate for sysadmins.
Specifically, we’ll use Traefik to set up TLS secured access (a.k.a. https) to Qlik Sense, while at the same time establishing a solid platform to which we can add more features in coming blog posts.
Starting with the basics makes sense though – let’s get to it!
This release both adds some nice new features as well as enhancing existing ones and fixing some bugs. Let’s take a look at the highlights.
Track in detail whatapps are loaded into each Sense server.
Regular apps and session apps are handled separately, making app metrics easier to understand and more relevant
Sample dashboards are now built using the brand new, shiny and all together awesome Grafana 7. Did I mention that Grafana 7 is awesome? Awesome.
Ever wondered how long Butler SOS has been running or how much memory it uses? The new uptime messages have you covered.
You are properly impressed with the uptime messages – good. Why not store them to Influxdb, so you can also visualize Butler SOS’ own memory use? It’s just a couple of changes in the config file away.
Better control over what features are enabled. Don’t need Docker health checks? Now you can turn that (and other) feature off.
Ah, you are a serious Sense user and have separate DEV and PROD environments? Good – now Butler SOS supports multiple instances running on a single server.
Who will monitor the monitor? Butler SOS can now send heartbeats to customisable URLs at desired intervals. Perfect if you want to monitor Butler SOS using for example healthchecks.io. Very, very cool actually.
Bugs, bugs and bugs. The known ones have been fixed. Keep reporting new ones!
Update all dependencies to latest versions, to ensure security concerns are adressed.
Curious what it looks like in practice? Seeing is believing:
Qlik Sense is very much my go-to tool for many data related questions. It’s very powerful to be able to throw together a proof of concept or test a hypothesis in half an hour. Seeing is however believing, so those prototypes does need some polishing before they can be seen as production grade.
I have always pushed my peers in the Qlikosphere to become better at using icons for their Qlik Sense apps in general, and also for the sheets within those apps. Having an icon for a sheet within an app makes it way easier for the user to find a particular sheet – humans are visual by nature.
Butler SOS 4.0 is out, adding features that make it easier than ever to monitor large Qlik Sense environments. We’ll return to this topic of course, but let’s first take a few steps back.
There are many variants of that quote: “If you can’t measure it, you can’t improve it”, “Measure what matters”, “Measure what is measurable, and make measurable what is not so.” and others. The last one supposedly originates with Galileo Galilei. Smart guy.
The development of Butler SOS continues in that spirit. Qlik Sense provides an awesome platform on top of which all kinds of data analysis, visualisation and presentation solutions can be built. A key word there is platform. Sense does not offer solutions to all software development challenges, nor should it. Instead, use the tools and best practices that millions of developers around the world have refined over the years.
Qlik Sense does on the other hand offer a very comprehensive set of APIs that give developers access to its internals – and this is part of why it’s such a powerful platform. Butler SOS taps into some of these APIs, exposing their data in the form of real-time dashboards, charts and alerts. Suddenly sysadmins know can get both an overview of how all servers are doing, as well as look at detailed server metrics when so needed. All made possible using the Sense APIs, but in general powered by various open source tools.
We’re basically back to Galileo – let’s make sure the important parts of Qlik Sense are measurable. It is then possible to improve the parts that don’t work well.
The basics are the same, i.e. one-click creation of Qlik Sense apps, using regular Sense apps as templates. Several new features however take the tool to a new level, making it easier to set up, manage and more enterprise grade. Good news thus!
