Lists log groups, optionally only those whose name starts with a prefix like /aws/lambda/.

List log streams

Search log events

Finds a log group's events in a time range that match a filter pattern: a word or "quoted phrase" (ERROR, "timed out"), terms like ?ERROR ?WARN for either, or a JSON pattern like { $.status = 500 }.

Read a log stream

Reads one log stream's events in order, newest last, optionally in a time range.

Start a Logs Insights query

Starts a CloudWatch Logs Insights query over up to 50 log groups and a time range in seconds since 1970, like fields @timestamp.

Get query results

Gets a Logs Insights query's status (Scheduled, Running, Complete, Failed, Cancelled, Timeout) and, once Complete, its results.

Create a log stream

Creates a log stream in a log group, to write events to with "Write log events".

Write log events

Writes up to 10,000 events to a log stream, each with a timestamp in milliseconds since 1970 (in order, within the last 14 days) and a message up to 1 MB.
