# Key-Value

**Analytics → Key-Value** is the Metrics Browser: time series of key-value metrics the agent recorded (including custom series your application or plugins publish).

{% hint style="info" %}
**Screenshot placeholder:** Workstation → Analytics → Key-Value. Empty state “No metrics to display”, then a Time Distribution chart after a search.
{% endhint %}

Open **Search** and set:

* **Date range** — required
* **Application** — required
* **Key** — type at least three characters to search available metric keys, then select the series to plot

The chart shows the selected symbol over the chosen window. Use it alongside [Data Analysis](/7/user-guide/observing-and-diagnosing/data-analysis.md) when you need numeric series rather than individual invocations.

OpenTelemetry **traces** are ingested separately (see [OpenTelemetry](/7/user-guide/opentelemetry.md)). This page is for key-value series stored by the Flopsar server, not for OTLP metrics (the server does not ingest OTLP metrics or logs).
