* FINEST (lowest value)
To get a detailed view of Petals logging mechanisms, please refer to the page [petalsesbsnapshot:Monitoring Petals ESB Flows with its logs].
h2. Default levels
The default root logger level is WARNING. It means that all classes log only SEVERE and WARNING information.
The default Petals root logger level is INFO. That's why all Petals components will log only SEVERE, WARNING and INFO information.
The default components level is MONIT.
You can enable logging and specify a specific level for each module (container, component, cdk...). Here is how you would set debugging from Petals. You would need to ensure the Handler's level is also set to collect this threshold, so FINEST or ALL should be set.
{code}
##Petals level
Petals.level = FINEST
#Handler Configuration
java.util.logging.ConsoleHandler.level = FINEST
{code}
Example of configuration to debug (Level FINEST) petals-bc-soap component:
{code}
##Petals level
Petals.level = INFO #Log level for all petals services
Petals.Container.Components.level = MONIT #log level for all components
Petals.Container.Components.petals-bc-soap.level = FINEST #Log level for petals-bc-soap component
#Handler Configuration
java.util.logging.ConsoleHandler.level = FINEST
{code}
h2. Petals formatters
PetalsFormatter uses the following pattern:
{panel:borderStyle=solid}{+}Petals Node Name+ +YYYY/MM/DD+ +HH:MM:SS,FFF+ +LOG LEVEL+ +LOGGER NAME+ : ?\[LOG MESSAGE\]
\[EXTRA DATA KEY\] = '\[EXTRA DATA VALUE\]'
\[JAVA EXCEPTION\]{panel}
*Example of logging output with PetalsFormatter:*
{panel:borderStyle=solid}
node1 2011/08/25 15:44:44,426 GMT+0200 MONIT \[Petals.Container.Components.petals-bc-soap\] : traceCode = 'consumeFlowStepBegin',flowInstanceId = '62cdea40-cf20-11e0-bdfa-000c29523cc7',flowStepId = '62ce3860-cf20-11e0-bdfa-000c29523cc7',flowInterfaceName = '\{[http://usecase1/bpel-P12/]}interfaceName1',flowServiceName = '\{[http://usecase1/bpel-P12/]}serviceName1',flowEndpointName = 'endpointName1',flowOperationName = '\{[http://usecase1/bpel-P12/]}process',client = '192.168.1.157',requestedURL = 'http://192.168.1.196:8084/petals/services/soap-C1'
{panel}
{info:title=Default behavior}One or both previous formatters are always used during execution, unless default handler formatters in ../conf/logger.properties are changed
{info}
If following formatter is applied for both handlers:
*org.ow2.petals.kernel.logging.PetalsFileHandler.formatter = org.ow2.petals.kernel.logging.PetalsFormatter*
*java.util.logging.ConsoleHandler.formatter = org.ow2.petals.commons.logger.PetalsFormatter*
All logs are processed by the PetalsFormatter whether we are in _FINEST{_}_, SEVERE, CONFIG ... MONIT_, but
the both previous log traces are written if the level *MONIT* is precised.
h2. Splitting log files\\
Petals ESB allow to split its log records into a log files hierarchy. This is done thanks to the PetalsFileHandler which can redirect log records to separate according to Petals ESB runtime properties.
In addition to standard Handler properties (level, formatter, etc..), PetalsFileHandler can be configured through the following extra properties:
* basedir: base directory where log files will be stored. Default value (if no property set) is user home directory.
In this base directory, you'll find two things:
* a *petals.log* file which contains all petals container logs
* a *flow-monitoring* sub-directory which contains flowInstanceId sub-directories (one per flow instanciation).
h2. Logged informations
Following informations are +common{+}{+}s+ to both formatters:
* Petals Node Name
* Timestamp
* Logger level
* Logger component name
* Log message
We can found more informations about previous concepts in glossary [Glossary|http://doc.petalslink.com/display/glossary/Petals+ESB+specific+vocabulary]
{warning:title=Environment variable}
Take in account if the following variable is define or not:
_\-Djava.util.logging.config.file=$PETALS_HOME/conf/loggers.properties"_
Because, if the previous argument on your Petals process is setted to another logging file, the loggers.properties under /conf +will not be take in account+.
This setting can create a real problem, you do not necessarily understand where it comes directly
