export

Retrieves events from a Tenzir node.

export [live=bool, retro=bool, internal=bool, parallel=int]

Description

The export operator retrieves events from a Tenzir node.

This operator is the dual to import.

live = bool (optional)

Work on all events that are imported with import operators in real-time instead of on events persisted at a Tenzir node.

Note that live exports may drop events if the following pipeline fails to keep up. To connect pipelines with back pressure, use the publish and subscribe operators.

retro = bool (optional)

Export persistent events at a Tenzir node. Unless live=true is given, this is implied.

Use retro=true, live=true to export past events, and live events afterwards.

internal = bool (optional)

Export internal events, such as metrics or diagnostics, instead. By default, export only returns events that were previously imported with import. In contrast, export internal=true exports internal events such as operator metrics.

parallel = int (optional)

The parallel level controls how many worker threads the operator uses at most for querying historical events.

Defaults to 3.

Examples

Export all stored events as JSON

export
write_json

Get a subset of matching events

export
where src_ip == 1.2.3.4
head 20
