New Features

Editable e-mail templates

The E-mail Templates used for alert and trend notification are now configurable per tenant.

Monitoring Plugin

We're releasing a Studio Plugin that offers a overview of the health of the System to establish the system health without the need of logging into the system and any sysadmin skills.

• Status of all services on all cluster nodes
• Status of all Elasticsearch instances
• Overview of all Elasticsearch Indices, including health state, size, number of documents etc.
• Status of the Pipeline/Ingester with current activity and errors etc.

OpenSearch API

We added a Studio Plugin that exposes an OpenSearch API compatible endpoint of the Squirro search interface. This endpoint can for example be used to integrate Squirro search results into Salesforce via federated search. See Salesforce Federated Search for further instructions on how to do this.

Contextual Help

In order to make the Squirro experience simpler, we have added contextual help to nearly every page inside the Setup and Server spaces. To access this help, all you need to do is click on the question mark icon on the top right corner and choose the "Explain this page" option. Relevant links will guide you directly to documentation where you can discover all about the page you're on.

We are working towards making Squirro more intuitive and easy to use, shaping the learning curve as steep as possible to ensure that users can quickly grasp the tools and techniques in a very short time.

Improvements

Machine learning service

2.6.1. brings improved stability and robustness to the Machine Learning Service. For better vision into how different jobs run (or fail), we've added API access to run logs. If you notice a problem, we've also added the ability to kill jobs. For model tuning, we're now recording model performance per training batch, and for model validation, we've adjusted the Heatmap widget to be used effectively as a confusion matrix. Finally, as we are trying to make the process of creating and deploying machine learning models more efficient, we're providing a simple example pipelet that can tag ingested documents with a pre-trained model. To see it in action, we recommend following the provided walkthroughs. 

Recommendations

Recommendations get a new look in 2.6.1. We've converted our custom widget into a standard product widget with several UI improvements both in creation and display. These include more accurate feature counts, tighter integration with the Machine Learning Service, and pagination on entities result lists. NOTE: This feature is still considered in ALPHA, so please speak with our team before deploying.

Mobile dashboards

• The Mobile Dashboard Editor is a new addition to the dashboard editing tool. It allows you to edit and maintain a mobile version for each dashboard. The web and mobile version of a dashboard share the same URL. While the web mode of a dashboard renders on all web-like and tablet screens, the mobile mode of a dashboard renders on all mobile-like screens. While editing a dashboard, user is offered a switcher to switch between the two modes. The web and the mobile dashboards are synced by default. The sync can be turned on/off. As the desktop dashboard is the leading dashboard, re-syncing is uni-directional, i.e., it copies the layers and widgets from the web mode to the mobile and not the other way around.
• The mobile version of the dashboard is now launched with improved functionality and interaction patterns.
• Mobile dashboard widgets occupy full width and are stacked automatically. 
• Dashboard now has vertical scroll instead of horizontal swipe.
• Custom widgets are supported. 
• Some widgets might have reduced config. options based on optimisation for mobile.

Widget Browser

• The Dashboard Editor gets a new look.
• The widget selector dropdown is now replaced by a widget browser window which is easy to use and drastically cuts short the time and clicks required to build dashboards.
• Easy to find: Widgets browser now has built-in search functionality.
• Easy to locate: All widgets are listed in a tile view with representative icons.
• Easy to glance: A quick scroll allows you to glance over the entire widget library.
• Easy to build: Widgets can be dragged and dropped to the desired position on the dashboard.
• Time Saving: Multiple widgets can be added in one go, allowing you to put together a decent dashboard within seconds.
• Logical listing: All widgets are listed under functional categories: items, navigation, filters, over-time, distribution, geographic, special, others and custom.
• Descriptive: Every widget has a description displayed on hover over the widget icon. Custom widgets upload tool now supports description.

Project Browser

In the new Project Browser, the project dropdown is replaced by a slide in navigation drawer. The active project is highlighted. Add Project button is on the top of the projects list, thus eliminating the need to scroll to the bottom of the list to create a new project.
