Container log files

Containerized applications can be monitored by examining their log files.

The log files for containerized applications can be viewed on the Application Log Files page of the appliance, see Viewing application log files. A container log file contains all text that the container emits to standard out while it runs.

By default, container log files are rolled-over when they reach 10 MB or each time the container is started. The default number of rolled-over log files that are kept is 10. The maximum size of log files before they are rolled-over, and the maximum number of rolled-over files to keep can be customized. Customize these properties by specifying the logging/max_files and logging/max_size parameters when using the Container Deployment Management > Create Container Deployment REST API.

The log files can be sent to a remote syslog server using Remote Syslog Forwarding capability, see Forwarding logs to a remote syslog server.
