IoT Broker System Monitoring

Log Files

The IoT Broker is using the pax logging system. The logs are stored in the reportLog folder, a subdirectory of IoTBroker-runner.

The logger is configured in fiwareRelease/iotbrokerconfig/bundleConfigurations/services folder. An example of the org.ops4j.pax.logging file is shown below.

 log4j.rootLogger=INFO, ReportFileAppender, console
 #Console Appender 
 log4j.appender.console=org.apache.log4j.ConsoleAppender
 log4j.appender.console.layout=org.apache.log4j.PatternLayout
 log4j.appender.console.layout.ConversionPattern=%d{ISO8601} | %-5.5p | (%F:%M:%L) | %m%n
 #Solve the digerest Tomcat logger errors
 log4j.logger.org.apache.commons=WARN
 log4j.logger.org.apache.commons.beanutils=WARN
 log4j.logger.org.apache.struts=WARN
 #File Appender
 # ReportFileAppender - used to log messages in the report.log file.
 log4j.appender.ReportFileAppender=org.apache.log4j.FileAppender
 log4j.appender.ReportFileAppender.File=.//reportLog//report.log
 log4j.appender.ReportFileAppender.layout=org.apache.log4j.PatternLayout
 log4j.appender.ReportFileAppender.layout.ConversionPattern= %-4r [%t] %-5p %c %x - %m%n

In the example above, the log level is selected in the first line. The possible log levels are:

• log4j.rootLogger=INFO
• log4j.rootLogger=DEBUG

Monitoring Panel

The IoT Broker has a monitoring panel that is accessible via the "admin login" button on the index page web page. For login, the administrator should use the ADMIN credentials. These credentials are set in the configuration file fiwareRelease/iotbrokerconfig/iotbroker/config/users.properties. The default username and password are (ADMIN, admin).

The Monitoring panel is accessed via an HTTPS connection based on an SSL certificate. In the fiwareRelease/iotbrokerconfig/iotbroker/https folder there is already a dummy key, but for security reason the admin should generate a private key containing a valid certificate. A simple way to generate one of these is to use Java's keytool utility located in the $JAVA_HOME/bin directory.

Example: ``` 'keytool -genkey -alias admin -keyalg RSA -keystore ...\fiwareRelease\iotBroker\https\key.keystore'
