Splunk is shining its light on Dark Data and enabling companies to extract real business value from their machine data. As the value of that newly exposed information increases, it is important to be able to access it from anywhere, even from mobile devices. Although a Splunk mobile app has been available for a few years, connecting to an on-premises Splunk Enterprise deployment was difficult. The mobile device needed some type of VPN software to access Splunk dashboards, or there were more complicated meth... read more.

Splunk allows the transformation of dashboards into forms, which present controls for users to enter search criteria. This allows you to have text boxes, pulldown lists, checkboxes, radio buttons, and other controls at the top of the form. The user’s selections from these input controls are stored in tokens that you can use in your queries or to control various aspects of the form. You can also add these input controls to specific panels on your form, not just at the top of the page. This makes it... read more.

One common field type that often has multiple values is an e-mail address field, such as from or to. Splunk deals with these values by allowing fields to hold multiple values, which it refers to as simply a “multivalue fiel... read more.

Machine Learning is a broad concept covering algorithms that can receive input data and use statistical analysis to predict an output value within an acceptable range. It analyzes past data to predict future data and to provide context for the current values. In a sense, the machine has learned how this metric “behaves” and can put parameters around the current value (standard deviation, probability bands, etc.), adding knowledge that isn’t obvious if all you have is the single, current me... read more.
