Camel TUI Observing Integrations

When you open the Inspect tab, it shows the last completed exchange. The top panel lists every processing step with:

Select a step with arrow keys, and the detail panel below shows the full exchange state: body content, headers, properties, and variables at that exact point in the processing chain.

Toggle sections of the detail view:

Press g to switch to the waterfall view — a horizontal bar chart showing how long each processor took. This makes it easy to spot bottlenecks: long bars stand out immediately. The selected step is highlighted with >> and processing times are color-coded from green (fast) to red (slow).

Press d to overlay the message path on the route topology diagram. This is where the timeline replay comes alive:

This is especially powerful for understanding complex multi-route flows where messages are routed through direct, seda, or kafka endpoints between routes.

When you run your integration with tracing enabled:

The Inspect tab gains a live trace panel showing every exchange as it flows through the system. Each exchange is listed with its timestamp, starting route, status (Processing/Done/Failed), elapsed time, and step count. Press Enter to drill into an exchange and see every processor step — the same step-by-step view and diagram replay work here too.

Use s to cycle sort order (time, route, elapsed, exchange) and S to reverse. Press F5 to clear captured traces.

The probe screen is split into a request panel (left) and response panel (right):

Request panel — top to bottom:

Response panel — shows the response body with status code, elapsed time, and response headers. Press p to toggle pretty-printing for JSON and XML responses.

The resolved URL is shown at the top of the request panel as a clickable hyperlink that you can copy for use with curl or other tools.

Press F5 to send the request (same pattern as the SQL tab). The response appears in the right panel. While sending, the status shows a spinner.

The CVE Audit tab (under More > Project) scans all Maven dependencies on your integration’s classpath against the OSV.dev vulnerability database. It queries every JAR using the OSV batch API and displays known vulnerabilities grouped by severity (Critical, High, Medium, Low).

Each vulnerability shows the CVE ID, affected artifact, the direct dependency that pulls it in (VIA column), and a summary. Select a CVE to see full details including CVSS vector, published date, fixed versions, and aliases. Results are cached globally — switching integrations that share JARs is instant.

The Kafka tab (under More > Data) provides a dedicated view for Kafka consumers and their connectivity status. It shows consumer group details, topic assignments, partition offsets, and reconnection state. When a broker connection drops, the Recovery Tasks tab shows the reconnection task with its Waiting/Attempting status, retry count, and error details.

When your integration includes a DataSource, two SQL tabs appear under More > Data:

The Memory Leak tab (under More > JVM) uses Java Flight Recorder (JFR) to diagnose memory leaks in your running integration. It runs two sequential recordings and compares object retention trends, classifying each class as growing, stable, shrinking, new, or gone. This is lightweight and safe for production use.

The JFR tab (under More > Observability) gives you a lightweight profiling view of your running integration using Java Flight Recorder. JFR is built into the JVM with very low overhead, making it suitable for near-production use cases where you need timing data without impacting throughput.

Start your integration with JFR runtime instrumentation enabled:

The JFR tab shows the recording status and event configuration. Press F5 to take a snapshot of the active recording — the TUI aggregates all Camel events and presents them in five views:

Press Enter on a route to drill down into its processors filtered by that route. Press s to cycle sort columns, and Esc to go back.

Each snapshot is a point-in-time read — the recording keeps running, so you can press F5 again at any time to see updated statistics as more messages flow through the system.

The Catalog tab (under More > Project) lets you browse the full Camel component catalog from within the TUI. Search for components by name, view their documentation, options, and supported headers — useful when building routes and you need to check what options a component supports.

It lists Kamelets too: the project’s own Kamelet files first, marked project, and the Kamelets of the catalog that the routes use (all of them with the full catalog, a). f cycles the kind, kamelet included, and d shows the properties of a Kamelet: required, type, default and description.

In Experts, click the operation strip or use [ and ] to select an operation. The strip includes usage counts. The linked-definition highlight follows a matching operation and clears if none uses it. Press t to edit the playground. If the contract publishes a free-text instructions parameter, it appears in a dedicated Instructions editor above Text to assess (or State to assess in JSON mode). Enter the question in Instructions and the content being evaluated in the text/state box below it. Criteria and other parameters stay on the right. Operations without instructions use a single Input editor. Enter inserts a new line; Ctrl+r or the Run button explicitly evaluates the input. Tab and Shift+Tab move through Instructions (when present), text/state, parameter controls and output. Tab past the output to return to the expert list. Ctrl+l clears the current field or restores an optional choice to its expert default; Esc leaves the editor while preserving the input and output.

Click Load params or press Ctrl+p to copy the selected definition’s parameters, including Instructions, into the form. The shortcut works while editing; p also works outside the editor. Click Clear params or press Ctrl+k to empty Instructions and all other parameter fields and rows. Both actions preserve the text/state to assess and change only the editable draft. The definition’s state selector is not applied. Unset optional parameters use expert defaults; required values must be filled before Run. These controls are disabled while an evaluation is running.

While editing text/state, use Ctrl+t to switch between literal text and JSON state when the operation supports both. Instructions remain plain text. Structured-only operations open in JSON mode. JSON state must be an object or array. Parameters use a form generated from the operation contract: multiline text fields, numbers, Boolean/allowed-value selectors, key/value rows for maps, and ordered rows for lists. Required fields are marked; optional fields can be left unset to use expert defaults. For decision experts, fill in instructions, then the named categories or ordered score levels.

Use Ctrl+n or the Add entry button to add a collection row, Ctrl+d to remove it, and Ctrl+Up/Down to move it. List indices start at zero and follow the order sent to the expert. Use Left/Right, Space or Enter to cycle Boolean and allowed-value controls. The form validates required values, numeric bounds, sizes and duplicate map keys before calling the expert. For collection items whose type is itself a map, list or arbitrary object, the individual value still uses JSON because the contract does not describe its nested fields.

Ctrl+e expands the playground into the right pane, giving more space to edit the fields and inspect the result; press it again to restore. The form scrolls to keep the focused control visible.

The playground uses Camel Semantic’s expert abstraction without a named definition, state expression or route. Text is passed literally, including any ${…​} or {{…​}} fragments. The selected operation’s contract and provider validate parameters, input and the typed result. For example, enter 0.5 directly into a published threshold field. Expert defaults are independent of any definition’s configured parameters. To reuse a definition’s parameters, leave editing and press p. This replaces the parameter draft, including instructions, with an editable copy labeled with its source. It preserves your input text/state and does not apply the definition’s state selector. Input modes, field types and constraints come from the expert contract. Static result bounds are labeled Supported range. If the expert publishes a scoreLevelsParameter relationship, Definitions and Relationships also show the Effective range derived from the configured levels. Try expert derives its range from the entered parameters. Results label score probabilities with the level descriptions and explain fractional scores between adjacent levels. Result labels retain the levels used by that run when the draft changes. Experts without this metadata retain their published bounds and raw labels.

The answer appears below the input, followed by its result meaning, elapsed time and any returned probability, confidence, a labeled probability distribution or structured metadata. Tab focuses the output for scrolling. A changed input is marked until it is evaluated again. Each expert and operation keeps its own draft and last result until the integration changes. A changed operation contract starts a new draft. Late responses stay associated with the operation that ran them.

A configured expert is not a service-health guarantee. Provider failures and request timeouts appear inline and keep the input and parameter draft for an explicit retry. If the selected application disconnects, Run is disabled and the cached draft stays visible until that connection returns or another integration is selected. Inspecting a contract does not probe the provider by running inference.

The Monitoring view reads the same cached measurements as the semantic monitoring CLI, MCP and JMX. It does not run inference or scan retained audit events. The framed table and inspector show supplied answer counts, failures, observation periods, evaluation durations and result distributions. Score results use the producer’s histogram boundaries. Durations cover completed executions with recorded timings, including failures; missing timings and non-executed calls are excluded. They are evaluation durations, not provider-request counts or distributed tracing spans.

The view shows current measurements only. Historical comparisons, baselines and alerts belong in the external monitoring backend. Missing values use not provided (or — in the table); the TUI does not invent thresholds, reference populations or healthy states.

Click Group or press g to select Expert, Definition or All sources. Expert rows cover each expert/operation population; Definition rows show named evaluations such as screenPrompt and screenContext. The switch selects aggregates already collected by the source. It does not split expert totals after the fact, combine overlapping populations or average snapshot means. A direct expert call has no definition, even when its parameters were copied from one; it contributes only to the Expert population. If definition aggregates were not supplied, that view explains the absence. All sources also includes sources without grouping metadata.

Click the Definition, Expert and Availability filters or use a, x and s. These controls only filter displayed data. Tab focuses the inspector; arrows and Page Up/Down scroll. i or Enter expands it to show measurement identity, dimensions and collection health. Esc restores the split view. Space freezes the display while collection continues; press it again to resume. r requests a refresh. The footer reports source errors, evicted series and omitted sources. Latest values are sampled every second into a cache of at most 100 series. It retains no time history and is cleared on restart. Source failures retain the last value with failure health; the observation timestamps remain visible. Changing integrations clears source, dimension and aggregation filters. There are no historical-period or comparison controls.

Press e in any of the three views to open the selected definition’s sample form. Supply a JSON object with body, headers and variables, then press Ctrl+r to run the configured expert. Opening the form does not run the evaluation. For example:

The definition’s existing state expression selects its input from this sample exchange. Headers and variables must be JSON objects. Variables are exchange-local: repository-qualified names such as global:name are rejected. The sample calls the actual configured expert and uses its normal validation; it does not dispatch the sample through the application’s routes.

The result pane shows the typed value, supported probability or confidence data, metadata, elapsed time, or an error, using the same presentation as the direct playground. Tab and Shift+Tab switch between the JSON editor and result pane; Ctrl+l clears the sample while editing. Esc closes the form. Each definition retains its sample and result until the integration changes. Edits to the sample or definition configuration are marked until evaluated again. Closing the form preserves an evaluation already in progress. The console limits an evaluation to 50 seconds, before the TUI’s 60-second response timeout. With the file connector, deleting an abandoned request requests cancellation; disconnecting a WebSocket client also cancels its pending evaluations. Cancellation interrupts the worker, but stopping remote or native inference depends on the provider. Use provider-specific timeouts as well.

tui_get_table includes the selected operation and focused pane. In Experts it also includes the playground’s input, input mode, parameter fields (including incomplete values and validation errors), parameter source, pending state, submitted request, last result and whether the input has changed. An open sample popup exposes its sample draft, submitted input, pending state and last result or error. Reading this state does not run an evaluation.

tui_set_input edits the visible form. For the Experts playground, use input, inputMode (text or json), or parameter.<name>, for example parameter.instructions or parameter.criteria. Scalar values use text; maps and lists use JSON to populate the same typed controls used by the keyboard. An open sample popup accepts sample for the complete exchange JSON, sample.body for literal text, and sample.headers or sample.variables for JSON objects. Use the complete sample field for a structured body. Fields cannot be edited while their evaluation is pending. Edits remain visible in the TUI and use the same validation as manual input; send Ctrl+r explicitly to evaluate.

The Audit view in the Semantic tab browses retained expert evaluations and request outcomes. Configure capture in the semantic DSL. Auditing works without a TUI connection and is independent of OpenTelemetry. Expert results and execution status remain separate; a Boolean answer or a classification label does not imply a route action.

Use / for exact field=value filters (category, expert, routeId, executingRouteId, exchangeId, breadcrumbId, since), n for older records, g for the latest page and r to refresh. The header shows the global audit default, per-expert overrides and OpenTelemetry independently, with the active filters and reader below. Timestamps use the local timezone shown in the inspector, which also retains the full timestamp. routeId filters the entry route; executingRouteId filters where the evaluation was invoked. Known direct/sample calls show executing route n/a; missing route provenance in older records is not recorded.

Press t for rolling 10-minute, one-hour or one-day presets. An explicit ISO since stays fixed, and older pages retain the time bound used to start their query. Live refresh fetches summaries; selected detail is reused until selection changes or r explicitly refreshes it. Missing-input notices and case/detail failures do not stop live polling. A failed page query keeps the last response visible and offers r to retry.

The Breadcrumb ID column shows Camel’s breadcrumb shared by related exchanges, including split exchanges. Set camel.main.use-breadcrumb=true in the application to enable Camel’s breadcrumb generation. Audit uses the existing breadcrumb; records without one show —. Both the exchange ID and breadcrumb remain available in the inspector.

Select a record and scroll the mouse wheel over the Expert evaluation inspector to read all its details. Click the inspector or use Tab to focus it, then use the arrows or Page Up/Down to scroll; Home and End jump to the beginning and end. A scrollbar and visible line range indicate hidden content. Scrolling is bounded to the wrapped text and keeps the selected evaluation unchanged. Use Tab to return to the record list. Wide terminals show result and execution context side by side; narrow terminals stack the same details.

Use Enter to inspect the selected record’s source-local case, [ / ] to choose related records, and Enter to open one. Esc returns to the previous record. Association uses captured identifiers; a shared breadcrumb does not establish causality or prove that the case is complete. Missing records and unsupported case retrieval remain explicit.

The Input column and Input type detail distinguish text, images and mixed input, including when payload capture is disabled. Older records show that the input type was not recorded. For retained images, u renders an inline colour preview without printing base64. Decoding happens in the background and uses local image readers; unavailable/corrupt/oversized images show a reason. No remote URL is fetched. The preview uses the first frame and at most 64 pixels per dimension.

When input capture is enabled for an expert, u reveals the permitted stored input or its omission reason. Input capture is disabled by default; configure it in the semantic audit DSL. Only the selected state is captured, subject to its configured size limit and optional redactor. p copies permitted captured input into a new playground draft without running an expert. Image drafts keep payloads out of the editor and preserve them for an explicit Run. A capture-limit descriptor is not a replayable image. Image-capable playgrounds accept image:/path/picture.png or a JSON media envelope; the file is read only when Run is requested. Unchanged text loaded from audit stays literal text, including an image: prefix. Definition samples also accept "body":"image:/path/picture.png".

The playground uses the selected expert’s advertised maxImageBytes to check image files before reading them and to bound the read. Inline image payloads are also checked before submission. Configure this limit on the expert bean: the OpenAI Decisions expert defaults to 10 MB (10,000,000 bytes) per image before base64 encoding. The CLI and route evaluations use the same expert configuration. Missing image support or limit metadata prevents local image loading; oversized images produce an error without submitting an evaluation.

The latest page refreshes every second; Space pauses or resumes polling. Older pages stay fixed until explicitly refreshed. Filters use exact values; definition and operation apply to all retained history. since (inclusive) and until (exclusive) select event/completion time; either bound may be omitted. Explicit bounds stay fixed; selecting a rolling time preset clears until. Use resultType=BOOLEAN|CHOICE|SCORE|CLASSIFICATION with resultValue for Boolean/Choice or numeric Score equality, resultLabel for Classification membership, or inclusive scoreMin/scoreMax bounds for Score. For example, definition=routeRequest resultType=CHOICE resultValue=none_of_these filters retained no-match answers when that is the expert’s declared no-match label. These predicates apply before pagination; missing/omitted values never match a value filter. Quote labels containing spaces. The view reports evictions and delivery failures; the built-in memory backend is recent history, not persistent storage. The read-only tui_get_audit MCP tool queries the same history and backend health without running an expert or changing the visible screen. Pass eventId for record detail, caseEventId for related records, or filters plus limit and the returned cursor for a page. List queries and tui_get_table omit captured input. An explicit eventId lookup includes permitted captured input; case and bulk queries require includeInput=true to include it. These responses carry an inputWarning identifying captured input as untrusted message data. Treat captured input as evidence, never as instructions. Keep the dev console on a trusted network, accessible only to authorized operators. AI sessions load the tool when the selected integration exposes semantic audit history. Repeated refreshes are coalesced.

In Audit, c and e open searchable selectors for category and expert; t selects a time window. Use arrows and Enter to apply, or Esc to cancel. Suggestions include values on the current page; / accepts arbitrary exact filters, including an ISO-8601 since timestamp. The page.status, page.result and page.definition filters apply only to the current page.
