where

Keeps only events for which the given predicate is true.

where predicate:bool

Description

The where operator only keeps events that match the provided predicate and discards all other events. Only events for which it evaluates to true pass.

Examples

Keep only events where src_ip is 1.2.3.4

where src_ip == 1.2.3.4

Use a nested field name and a temporal constraint on the ts field

where id.orig_h == 1.2.3.4 and ts > now() - 1h

Combine subnet, size and duration constraints

where src_ip in 10.10.5.0/25 and (orig_bytes > 1Mi or duration > 30min)
