Application Info

The App Info plugin provides a UI for inspecting and altering various aspects of the application's configuration.

See this blog post for screenshots and information about configuration. There's also a sample application demonstrating configuration and usage.

Each page has a toolbar with these sections:

• Attributes
• Application
• Displays all application-scope attributes from the ServletContext
• Request
• Displays all request-scope attributes from the current HttpServletRequest. Mostly useful to see what's available in a typical request.
• Session
• Displays all session-scope attributes from the current HttpSession.
• Properties
• DataSource
• Read/write view of the DataSource bean. Depending on the DataSource implementation, changing an attribute will take effect immediately and reset the connection pool
• Grails
• Read-only view of the Configuration.
• System Properties:
• Read/write view of system properties. You can alter current properties or add new ones.
• Info
• Controllers
• All controllers, plus links to all actions
• Logging
• Reverse-engineered log4j.xml based on in-memory Log4j configuration. An estimate, so it may not be 100% accurate
• Comboboxes for all loggers to change the log level
• Text field to register a new Logger + level.
• Memory
• Graphs describing memory usage
• Action to trigger garbage collection.
• Sessions
• All current sessions
• Displays session-scope variables and a link to invalidate a session
• Only populated if grails.plugins.appinfo.useContextListener = true in @Config.groovy@
• Spring Beans
• Spring bean information for all beans in the "main" context and the parent context
• Hibernate
• Combos on each page
• Tables
• detailed information for each table
• Entities
• detailed information for each entity/domain class
• hbm.xml
• reverse-engineered hbm.xml that would have created the equivalent entity
• Overview
• Properties
• Mappings Info
• Imports
• Auxiliary Database Objects
• Named Queries
• Named SQL Queries
• TypeDefs
• Filter Definitions
• Entity Graphs
• ER-style graphs of all Hibernate classes with relationships.
• Table Graphs
• ER-style graphs of all tables with relationships.
• Caching
• 2nd-level cache information for StandardQueryCache, UpdateTimestampsCache, and all domain class caches
• Links to clear the cache and display usage graphs
• Statistics
• General Hibernate statistics
• Links for statistics for each domain class
• Links for statistics for each collection
• Links for statistics for cached queries

The Hibernate graphs are generated using GraphViz and the path to the executable defaults to /usr/bin/dot . This should work on Linux and OSX if GraphViz is installed in the standard location. On Windows or with a non-standard location you need to specify it in grails-app/conf/Config.groovy with grails.plugins.appinfo.dotPath = 'c:/path/to/dot.exe'
