Metric Summary

The Metric Summary page shows all metrics in your system with their cardinality, type, unit, and labels. It helps you spot high-cardinality metrics that might slow things down and understand what labels are available for building queries.

What You'll Find Here

This page displays every metric groundcover collects, along with how many unique label combinations each one has. You can use it to:

• Quickly search for metrics by name

• Identify metrics with high cardinality that could impact performance

• See what labels are available for each metric

• Find the right metrics and labels when building dashboards and monitors

Page Layout

Search Bar

Use the search field at the top to filter metrics by name. The search is case-insensitive and matches partial names.

Example searches:

• groundcover_workload finds all workload-related metrics

• latency finds all latency metrics

• cpu finds all CPU metrics

Cardinality Chart

This chart shows total cardinality across all your metrics over the selected time range. You can track trends over time and spot sudden spikes that might indicate a problem.

The cardinality chart shows last 24 hours in 3 hour intervals

Metrics Table

The table shows details for each metric:

Column	Description
Metric Name	The full metric name, like groundcover_workload_latency_seconds
Type	Counter, Gauge, Summary, or Histogram
Unit	What the metric measures in (Seconds, Bytes, Number, etc.)
Cardinality	Number of unique label combinations in the past 24 hours. Higher numbers mean more unique time series
Percentage	What percentage of total cardinality this metric represents
Description	What the metric measures
Labels	Preview of available labels (click a row to see all labels)

Metric Details Drawer

Click any row to open a detailed drawer on the right. The drawer shows:

• The metric name at the top

• Navigation arrows to move between metrics

• A cardinality chart specific to this metric

• Two tabs with more information

Details Tab

Basic information about the metric:

Field	Description
Description	What the metric measures
Unit	Unit of measurement
Cardinality	Current unique label combination count
Type	Counter, Gauge, Summary, or Histogram

Labels Tab

All labels available for this metric:

Column	Description
Label	The label name, like namespace or pod_name
Cardinality	How many unique values this label has
Values Preview	Up to 3 example values

Use this information when building queries or identifying which labels contribute most to cardinality.

How to Use This Page
