Memfault indexes and aggregates the metrics collected by your devices to provide you not only with insights of how individual devices are performing, but also the emergent behavior of your entire fleet.
You can add charts to visualize these aggregated, fleet-wide metrics by navigating to the sidebar and selecting Dashboards and then Metrics.
Creating a new chart is as simple as clicking
Create Chart, selecting your
metric of interest, and choosing the desired aggregation type.
The list of metrics available in your project is automatically created from the metrics collected by your devices. For that reason, at least one device must upload data for a given metric before a chart for that metric can be created.
The aggregation of the metrics is done periodically, usually every few hours. To refresh the data inside a chart immediately, click the refresh button in the chart itself.
