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

Sections
- Report times - shows the time the report was generated and the time range of the report
- Environment - shows the JVM, operating system, and CPU information
- System Resources - shows JVM heap, physical memory, swap and file descriptor summary
- Resin Instance - shows the directories and files and Resin version. Also shows any startup messages.
- Licenses - shows the current Resin Pro licenses
- TCP Ports - status of the TCP listeners and threads at the time the snapshot was taken
- Health - The HealthCheck status of the server and a graph showing the status over time.
- Recent Warnings - Shows log warning messages before the snapshot was taken
- Recent Anomalies - Shows any anomalous behavior (like thread spikes) detected by Resin
- Cluster Status - shows the status of all the servers in the cluster as a set of graphs
- Server Graphs - graphs of the most important meters for the system over the measured time.
- Heap Dump - shows the most heavy memory usage for the system. You can use this as an initial
memory debugging.
- CPU profile - optional, when a profile is taken, will show the most heavily used methods
- Thread dump - shows the state of all threads in the system when the dump was taken
- Full log - shows all of the java.util log warnings over the time period
