Publishing Alerts |
|
Alerts are published by defining them on managed components and invoking the issueAlerts ( ) Web service operation on it. Here' s a sample code for issuing an alert.
try { } catch(LDAPException ldapEx) { // raise the alert defined earlier s_monitorStartLdapFailureAlert.issueAlert(ldapEx); }
Additional parameters can also be passed if the alert messages in the XML file have parameter place holders in the form of {0}, {1} and so on.
This can be done using another form of issueAlert() API such as alertDefinition.issueAlert(exception, object array);
Once the alert is issued, it gets published to the consumers configured in theLog4jConfiguration.xml. For example, if the consumer configured is a file appender such as aProcessNamedDailyRollingFileAppender, then all the alerts will be published to appropriate files in <Process_Platform_Installation_Directory>\logs directory.
A sample alert message published would be:
<log4j:event logger='com.eibus.management.AlertSystem' timestamp='1138694792285' level='ERROR' thread='main'> <log4j:message><![CDATA[<LocalizableMessage resourceID='Cordys.Integrator.Messages.monitorStartErrorLdapFailure> The Cordys Monitor could not be started due to failure to access the LDAP Server.
