For example, by having an ever-increasing total counter (e.g. Energy Consumption), you can display the variation per hour, day, or month without having to define additional counters with reset. ![](https://cdn.document360.io/6759e9c9-3ce3-49df-965a-7231d2d9a10a/Images/Documentation/image(504).png) ## New alert statistics To improve fault analysis, you can now use a new set of statistics based on alerts. For instance, you can display the MTBF (Mean Time Between Failures) or the MTTR (Mean Time To Repair) indexes. ![](https://cdn.document360.io/6759e9c9-3ce3-49df-965a-7231d2d9a10a/Images/Documentation/image(505).png) ## Action count statistic You can now display the number of actions that are already expired or are scheduled to be done in a short period. In this way, your users will be kept informed in case there is something to do urgently or not. ![](https://cdn.document360.io/6759e9c9-3ce3-49df-965a-7231d2d9a10a/Images/Documentation/image(503).png) ## Gauge widget with full support for statistics The gauge widget now also supports statistics more than metrics, including data loading, previous values increment, and period comparison. In this way, within a dashboard, you can display metrics and statistical values by using the same widget and style. ## Derived metrics with optional result You can specify whether a derived metric generates no values, in this way you can implement a logic that does not store any derived value in some specific cases. ## Minor bugs fix - Product registration widget usability improvements. - Gauge widget slow rendering. - Renewal token does not work in some cases. - Visual editor minor bugs.
