# Logs

Filterable subsets of all ingested data and all generated Metrics

The Logs page allows the user to inspect specific logs with certain properties defined by

* A specific time window (default: last 7 full days of data)
* Specific filters on [Columns](/v0.26.x/configuration/data-pipeline.md#columns) or [Metrics](/v0.26.x/workflow/metrics.md) (default: no filters)

{% hint style="info" %}
Typically, the Logs page is visited as part of investigating a specific [Insight](/v0.26.x/workflow/insights.md) or by clicking on part of a chart from a [Dashboard](/v0.26.x/workflow/dashboards.md), in which case the filters and time window will already be applied.
{% endhint %}

Individual Logs can be viewed in a variety of ways:

* [**Detailed View**](#log-detail-view): All [Columns](/v0.26.x/configuration/data-pipeline.md#columns) and [Metrics](/v0.26.x/workflow/metrics.md) of the log viewed together and optionally expanded.
* [**Trace View**](#log-trace-view) (if `spans` provided): The waterfall trace view of latency and timing for each individual span.
* [**Session View**](#log-session-view) (if `session_id` provided): All associated logs for the given session, along with [Metrics](/v0.26.x/workflow/metrics.md).

As part of inspecting the logs the user can

* View the filtered logs as charts and tables in the [Explorer](/v0.26.x/workflow/explorer.md)
* Save the specific filters as a [Segment](/v0.26.x/workflow/segments.md) to publish it on the [Segments Dashboard](/v0.26.x/workflow/dashboards.md#segments-dashboard)
