Metric Explorer

The Trendz Metric Explorer lets you validate which telemetries have data, review statistics, analyze time patterns, and explore general telemetry behavior for any device or asset. It also enables generating new metrics from existing ones using AI Assistance or AI Suggestions.

You can access the Metric Explorer by clicking the chart icon () in the Trendz navigation.

The interface has three main sections:

  ┌──────────────────────────────────────────────────────┐

Header — Entity, Item, and Timerange selection. Fields Section — Telemetries and attributes grouped by category. Tabs Section — Data analysis and visualization tools.

To begin, select an Entity (Device or Asset profile), an Item (Device or Asset) to explore, and specify the timerange for the analysis. These settings can be changed at any time.

After selecting the entity, item, and timerange, choose a metric (telemetry or attribute) for analysis.

Select an Entity (Device or Asset profile). Select an Item (Device or Asset) you want to explore. Specify the timerange for the analysis. Choose a metric (telemetry or attribute) for analysis.

The Fields Section shows all telemetries and attributes available in both ThingsBoard and Trendz, divided into up to six groups:

Anomaly — Anomaly Score or Anomaly Score Index from Trendz Anomaly Models. Attribute — Attributes from ThingsBoard. Calculation — Calculations saved by Trendz Calculation Fields. Generated Metrics — Metrics created by the Metric Explorer. Prediction — Predictions generated by Trendz Prediction Models. Telemetry — Raw telemetries from ThingsBoard.

If a telemetry you are looking for is missing, click Show Inactive Telemetries to display telemetries that exist for the item but have no data in the selected timerange. If it still does not appear, perform a topology discovery to sync the latest ThingsBoard structure with Trendz.

Click Show Inactive Telemetries to display telemetries with no data in the selected timerange. Inactive telemetries are now visible in the list. If the telemetry still does not appear, perform a topology discovery to sync the latest ThingsBoard structure.

You can also use the + New Metric button to create new metrics from existing ones. See Generate New Metric for details.

Lists all attributes of the selected item with their corresponding Trendz business entity fields. Clicking an attribute displays its current value.

Shows all telemetries of the selected item that have at least one data point in the selected timerange.

Each telemetry entry offers four analysis tabs:

Overview — Line chart or table view of telemetry values. Statistics — Basic statistical summary for the selected timerange. Time Patterns — Behavioral patterns across time units. Range Analysis — Distribution of telemetry values over time and range intervals.

Telemetries generated by Trendz entities (Calculation Fields, Prediction Models, or Anomaly Models). These use the same four-tab structure as regular telemetries, with an additional Go to Entity button for quick navigation to the related Trendz entity.

Go to Entity — navigate directly to the related Trendz entity. Go to Entity — opens the related entity in Trendz.

If a field does not appear in the expected group, ensure the Trendz entity is configured to save telemetry to ThingsBoard. Refer to the respective guides:

• Calculation Field — Save to ThingsBoard
• Prediction Model — Save telemetry
• Anomaly Model — Save to ThingsBoard

Displays metrics generated directly within the Metric Explorer. See Generate New Metric for details.

When a telemetry is selected, the Tabs Section displays analytical views for exploration.

Chart controls available in all tabs:

• Zoom — hold Ctrl and scroll with the mouse wheel to zoom any chart.
• Autoscale — when disabled, the Y-axis starts at 0 and ends at the maximum value; when enabled, the Y-axis fits the actual data range (min to max).

Autoscale disabled — Y-axis starts at 0. Autoscale enabled — Y-axis fits the actual data range.

Shows the historical trend of the selected telemetry within the timerange.

• Switch between Table and Line Chart views.

Table view of telemetry values. Line Chart view of telemetry values.

• Configure the grouping unit and aggregation method.

Configure grouping units. Configure aggregation methods.

Displays fundamental statistics for the selected telemetry within the timerange:

Analyzes telemetry behavior across time-based aggregations. Each chart can have an independent timerange and aggregation setting.

Hour of Day Distribution — aggregation by hour of day. Day of Week Distribution — aggregation by day of week. Weekly Heatmap — aggregation by hour and weekday. Calendar Heatmap — aggregation by calendar days.

Explores how long telemetry values stay within defined ranges. You define the ranges, and Trendz calculates duration and distribution statistics.

Setting up ranges:

1. Configure ranges with names, colors, and value limits.
2. Add or remove ranges as needed.
3. Reset to default (three automatically calculated ranges).

Configure ranges with colors and value limits. Remove ranges. Add ranges. Reset to default — three automatically calculated ranges.

After configuration, click Rebuild to generate the views:

Click Rebuild to generate the range analysis views. Summary Cards — total duration or percentage per range. Charts — duration or percentage grouped by time. Range Summary — most frequent range and the analysis period.

Chart customization options:

Value Aggregation — Duration or duration percent. Time Aggregation — select the time unit. Chart Type — Line Chart. Chart Type — Stacked Bar.

You can save a range configuration as a View using the Save View button, then embed it into a ThingsBoard dashboard. See Add View on Dashboard for details.

Click Save View. Click Save to confirm. The view is saved and available for embedding.
