Alpha/experimental features

Use of the following environment variables is unsupported, and the features are subject to change without notice:

• MQ_ALPHA_JSON_LOGS - Set this to true or 1 to log in JSON format to stdout from the container.
• MQ_ALPHA_MIRROR_ERROR_LOGS - Set this to true or 1 to mirror the MQ error logs to the container's stdout

Viewing the logs on the command line

The JSON-formatted logs are useful for forwarding to a log analysis system, but not very friendly when using docker logs or kubectl logs. You can format them using a command line utility like jq, for example:

docker run -e LICENSE=accept --rm -i -e MQ_QMGR_NAME=qm1 -e MQ_ALPHA_JSON_LOGS=1 mqadvanced-server:9.0.4.0-x86_64-ubuntu-16.04 2>&1 | jq -r '.ibm_datetime + " " + .message'
