Logs
Search, filter and export every span, trace and thread your app sends to Respan.
Logs lists every span your app sends to Respan, newest first. Open it from Observability › Logs or Gateway › Logs. Click a row to open it in a side panel. See Inspect spans and traces.
A red bar on a row’s left edge marks an error. An orange bar marks a warning, or a span where an issue behavior fired.
Search messages
Type words from a prompt or a reply into Search for spans… and press Enter. Logs keeps the spans whose messages match. Clear the field to drop the search.
The field follows the grouping, so it reads Search for traces… or Search for threads… there.
Message search needs the Team plan. On the Free plan, the field reads Search messages on the Team plan. Click Upgrade to Team to upgrade.
Filter logs
Pick the environment
Click All and pick Production (data sent with production API keys) or Test (data sent with test API keys or from the Playground).
Use the quick filters
Click Status, Behavior, API key, Provider or Model and check the values you want. Behavior keeps spans where an Issue, Win or Info behavior fired.
Filter on any other field
Click More filters and pick a field, such as Status code, Cost or Customer ID. Then set its value. Each condition shows as a chip, and the filter icon after the chips adds the next one. Click a chip’s value to change it, or its × to remove it.
Set the time range
In the panel above the table, pick 5m, 1h, 1d, 7d or Custom. You can also drag across the chart to zoom in, then click Reset zoom to go back.
How far back you can look depends on your plan. If you pick an older range, Logs shortens it to your limit.
| Plan | Time range |
|---|---|
| Free | Last 7 days |
| Team | Last 30 days |
| Custom | No limit |
Filter by custom properties
Click Custom property, find a property your app sends in its metadata (Search properties…), and pick a value. The property shows as a chip. To send custom properties, see Custom IDs & attributes.
Combine conditions
Chips join with AND. Click the AND between two chips to switch it to OR.
To mix both, open the filter menu, click Add filter group and add conditions to the group. A group joins its own conditions with OR (click to switch), and joins your other filters with AND. For example, a Customer ID chip plus a group of Cost and Output tokens shows that customer’s spans that were either expensive or long.
In Threads, chips that mix thread totals, such as Thread total cost, with span fields, such as Customer ID, can only join with AND. A note under the filters says so.
Group by spans, traces or threads
Click the grouping control in the filter row (it reads Spans by default) and pick what each row is.
| Grouping | Each row is |
|---|---|
| Spans | One operation, such as an LLM call, tool call or task. The default. |
| Traces | One end-to-end run, with every span inside it. |
| Threads | One conversation: the spans that share a thread_identifier. See Custom IDs & attributes. |
In Traces and Threads, a timeline of traces or threads replaces the signals panel. The old Traces and Threads pages now open Logs.
Some filters don’t work in every grouping. If one of them is on, Logs asks Remove filters before changing grouping?. Click Remove and continue to drop them and switch.
Customize columns
Click the gear icon (Column options) at the top right, or press D. Click the eye next to a column to show or hide it, and drag columns to reorder them. Custom properties and scores, when you have them, get their own sections.
After a change, click Save in the panel to keep it in the open view (on All logs, this starts a new view), or Reset to default to undo it.
Click a column header to sort by it, and click it again to reverse the order. Drag a header to move its column.
Save views
A view keeps its search, filters, environment, grouping, columns and time range. Views show as tabs at the top of Logs, and under Logs in the left sidebar.
Set up the view
Apply the search and filters you want. Reset and Save appear in the filter row.
Save it
On All logs, click Save. Logs adds a tab named New view. On a saved view, Save offers Save to this view or Save as new view.
Name it
Hover the tab and click the pencil (Rename).
Right-click a view tab for Copy view URL, Duplicate view, Edit view and Delete view. The icon after the last tab (New view) starts an empty view.
When every filter is an ID, such as Customer ID, Thread ID, Custom ID, Log ID or Trace ID, Share copies a link that opens Logs with the same filters, time range, grouping and environment.
Export logs
Open the export form
Click the export icon at the top right (Export logs) or press E, then click One-time export.
Choose what to export
Set the filters, time range, Sampling %, an optional Export name, the Columns and the File type (CSV or JSONL). The form shows how many spans match.
Start the export
Click Download CSV or Download JSONL. When the file is ready, download it from Settings › Exports.
- Recurring export exports the matching spans every 15 minutes.
- To export only some spans, check their rows, then click the export button in the bar at the bottom of the table.
- In Traces, the export icon (Export traces) exports traces. Threads has no export.
For export jobs, see Export. For how long logs are kept, see Data retention.
Blurred spans on the Free plan
On the Free plan, you can view the first 100,000 spans each calendar month. Respan still records every span after that, but Logs blurs their span name, model and messages, and exports stop at that point. Hover a blurred cell to see why, or click the row to open the plans page. Upgrading to Team shows them again.
Signals above the table
In the Spans grouping, the panel between the filters and the table counts spans, errors, Issues, Wins and Info over the time range. Click a row to open it, or a cell to see its spans. See Signals and errors.
To track a new pattern, click New custom behavior at the top right. See Behaviors.
