The Resin Application Server health system creates a PDF report summarizing the system's health by monitoring the Java VM, operating system and application server.

/resin-admin

The PDF report is available in the /resin-admin under the "summary" section. There is a PDF tab which prompts you to generate the port.

Command-Line Interface

The command-line "pdf-report" creates a report for the previous week and saves it in the servler's log directory. You can also get a copy to the local file system

Writing PDF report to a local file

unix> resinctl pdf-report -local -local-dir /tmp

generated /var/www/log/app-0-Snapshot-20120229T1356.pdf
Local copy is written to '/tmp/app-0-Snapshot-20120229T1356.pdf'
