---- jboss.system:type=ServerInfo

This service provides important information about the Management Server hardware and software environment, including:

•
AvailableProcessors
•
OSName
•
OSVersion
•
OSArch
•
JavaVMName (tells you 32 or 64 bits)
•
JavaVersion
•
MaxMemory
•
FreeMemory
•
ActiveThreadCount

---- jboss.jca:service=ManagedConnectionPool,name=jdbc/nitrogen

This service provides information about the database connection pool:

•
MaxConnectionsInUseCount
•
MaxSize
•
InUseConnectionCount
•
AvailableConnectionCount

---- jboss.web:type=RequestProcessor,*

This service provides information about slow HTTP requests that the server has processed:

•
requestProcessingTime
•
maxRequestUri
•
maxTime
•
processingTime

---- com.quest.nitro:service=Derivation

This is the derivation service. Its most useful attributes are:

•
DerivationRuletteCount—the number of derivation rulettes.
•
ComplexDerivationDefinitionCount—the number of derivation definitions.
•
EvaluationCount—the number of derivation evaluations made. From release 5.2.3, this is a delta value for the previous 30 seconds. Prior to release 5.2.3, it was a cumulative count from when the server started, so it was not as useful.

This service also provides more detailed information for each derivation definition, and each derivation rulette, including the number of evaluations, the last time it was evaluated, the result of last evaluation, and so on.
