WebEventsDownloadRequest

object1 direct reference

Definition

Request for the WebEventsDownload API. Accepts the same query as GetWebEvents (serviceName, eventNames, filter, timeRange, dataset, ordering) and returns the matching web events serialized as a downloadable file rather than as a JSON page.

The response is streamed, so the export is not paginated: a single request returns up to limit events, capped at 5000. Unlike the log and span exports there is no adaptive sampling to disable — web-event retrieval does not sample — so an exported file is the query's whole result set up to the cap.

There is no Dash0 CLI command for web events, so the cap is the only limit; a query matching more than 5000 events has to be narrowed to be exported in full.

FilterCriteria
TimeReferenceRangerequired

A range of time between two time references.

Dataset

Optional dataset to query across. Defaults to whatever is configured to be the default dataset for the organization.

OrderingCriteria

The ordering criteria for the exported web events. Events are written to the file in this order. Supported ordering key: otel.log.time (event timestamp, defaults to descending), optionally followed by dash0.web.event.id ascending, which is the tiebreak web-event retrieval appends to keep its cursor stable.

WebEventExportFormatrequired

The serialization format of the exported file.

  • txt: One rendered line per web event, carrying a fixed field set of timestamp, service, event name, title, duration and trace ID. Ignores columns.
  • ndjson: One OTLP JSON payload per line, each carrying a single web event inside the same resourceLogs envelope GetWebEvents returns — web events are stored as OTLP log records — so each line is independently parseable by any OTLP JSON consumer.
  • yaml: The same per-event OTLP payloads as ndjson, as a multi-document YAML stream with documents separated by ---.
  • csv: A header row plus one row per web event, flattened to the requested columns.
"txt""ndjson""yaml""csv"
integer

The maximum number of web events to export. Defaults to, and is capped at, 5000. A larger value is rejected rather than silently clamped.

string[]

Attribute keys to emit as columns, in order, for the csv format — resource, scope, or event attributes (e.g. service.name, event.name, dash0.web.event.duration). Ignored by the other formats, which have a fixed field set.
