Create Coval Dashboard

Create a new dashboard for $ARGUMENTS.

Instructions

Step 1: Verify CLI Authentication

coval whoami

If not authenticated, run coval login first.

Step 2: Create the Dashboard

coval dashboards create --name "Dashboard Name"

Capture the dashboard ID from the output.

Step 3: Identify Metrics

List available metrics to populate the dashboard:

coval metrics list
coval metrics list --include-builtin

Ask user which metrics they want to visualize. If they want metrics from previous runs:

coval runs list --page-size 10
coval runs get <run_id> --format json

Step 4: Add Widgets

For each metric, create a widget. Choose the visualization type based on the metric output:

Metric Output	Recommended Visualization
Float (numeric)	statistic, line, bar, histogram
String (Yes/No)	pie, bar
String (categories)	pie, bar, top-list

Before choosing widget sizes, consult references/grid-layout.md for the 48-column grid constraints and widget-type minimums.

coval dashboards widgets create <dashboard_id> \
  --name "Widget Name" \
  --type chart \
  --width <columns> --height <rows> \
  --config '{"metricId": "<metric_id>", "visualizationType": "line", "monitoring": "Simulations", "aggregation": "avg", "metricOutputType": "float"}'

Step 5: Verify Layout

After adding all widgets, list them and check the returned grid positions for gaps:

coval dashboards widgets list <dashboard_id> --format json

CRITICAL: Verify from the returned values:

• Each row's widgets sum to 48 columns wide
• No vertical gaps between rows
• Widget sizes respect type minimums per references/grid-layout.md

Fix any gaps by updating widget dimensions with coval dashboards widgets update.

Example

# Create dashboard
coval dashboards create --name "Q1 Agent Performance"

# Add a latency statistic (16 cols wide, 12 rows tall)
coval dashboards widgets create <dashboard_id> \
  --name "Avg Latency" \
  --type chart \
  --width 16 --height 12 \
  --config '{"metricId": "29BlkepvvX19ebbLDB0y6Q", "visualizationType": "statistic", "monitoring": "Simulations", "aggregation": "avg", "metricOutputType": "float", "precision": 2, "units": "s"}'

# Verify layout
coval dashboards widgets list <dashboard_id> --format json

Troubleshooting

Widget created but not visible

Cause: Grid position (grid_x, grid_y) may be null after creation. Solution: Update the widget with explicit grid positions using coval dashboards widgets update.

Widget dimensions changed from what was requested

Cause: The server enforces minimum sizes per widget type. Solution: Check references/grid-layout.md for constraints and use valid dimensions.

"Invalid request body" error on widget create

Cause: Config JSON is malformed or missing required fields. Solution: Chart widgets require all of: metricId, visualizationType, monitoring, aggregation, metricOutputType.
