Log customization

Customize Meilisearch logs with two experimental features: --experimental-logs-mode and --experimental-enable-logs-route.

Use --experimental-logs-mode to customize log output:

./meilisearch --experimental-logs-mode json

--experimental-logs-mode accepts either human or json. human is the default value.

For more information, consult this feature's GitHub discussion.

Activate the /logs routes during runtime using the /experimental-features route:

curl \
  -X PATCH 'http://localhost:7700/experimental-features/' \
  -H 'Content-Type: application/json'  \
  --data-binary '{
    "logsRoute": true
  }'

Use /logs/stderr to customize logging levels for the default logging system:

curl \
	-X POST http://localhost:7700/logs/stderr \
	-H 'Content-Type: application/json' \
	--data-binary '{
      "target": "milli=trace,index_scheduler=info,actix_web=off"
  }'

Use the POST endpoint of /logs/stream for focused debugging sessions:

curl \
	-X POST http://localhost:7700/logs/stream \
	-H 'Content-Type: application/json' \
	--data-binary '{
    "mode": "human",
    "target": "index_scheduler=trace"
  }'

Configure the stream using the same parameters as regular logging: mode and target. The stream will continue to run indefinitely until you interrupt it.

Use the DELETE endpoint of /logs/stream to interrupt a stream:

curl \
  -X DELETE http://localhost:7700/logs/stream
