CloudWatch Logs Browser
The CloudWatch Logs view takes you from log group to stream to individual events, and can follow a stream live.
Log groups and streams
Section titled “Log groups and streams”The log group list shows name, stored size, retention and creation date. Search matches the start of the group name, the same way CloudWatch does.
- Create log group with a name, a retention period (or never expire) and tags.
- Edit retention from the list. Choosing never expire removes the retention policy.
- Delete a group or a stream. Both ask you to type the name to confirm.
- Each group has a Tags tab with an editor.
Open a group to see its streams with their last event time and size.
Events
Section titled “Events”Open a stream to read its events. Each event shows its absolute and relative timestamp, and JSON messages are detected and pretty-printed. Copy any message with one click.
- Filter pattern: any CloudWatch Logs filter pattern, such as
ERRORor{ $.level = "error" }. - Time range: the last hour, 6 hours or 24 hours.
- Load more fetches the next 100 events.
- Export the events you loaded to JSON or CSV.
Live tail
Section titled “Live tail”Turn on Tail to follow a stream as it is written. StackPort streams new events over a WebSocket, checking the emulator every second, honours your filter pattern, and scrolls to the newest event. If the WebSocket cannot connect, it falls back to polling every few seconds.
