-/**
- * Wrapper around log4j and Nagios NRDP passive alarming for MSO.
- *
- * For local alarm logging, this class will look for an alarm log file name
- * in the servlet context parameter "mso.alarms.file". If none is found,
- * it will look for an MsoProperty of the same name. As a last resort,
- * it will use the default path "/var/log/ecomp/MSO/alarms/alarm.log".
- * It is expected that all alarms within an application will use the same
- * alarm file, so there is no way to dynamically add other alarm files.
- *
- * Alarms are logged as a simple pipe-delimited string of the format:
- * <dateTime>|<alarmType>|<state>|<detailMessage>
- *
- * This class also supports real-time Nagios NRDP alarming. If enabled via
- * MsoProperties, all alarms generated and logged to the local alarm file will
- * also be transmitted to a Nagios NRDP instance. NRDP requires 4 parameters
- * in service alarm events (all Mso Alarms will be Service Alarms):
- * hostname, servicename, state, detail
- *
- * The log file format is also intended to be compatible with Nagios NRDP for
- * non-real-time reporting. The command-line tool for sending alarms is
- * is "send_nrdp.php", which takes the same 4 parameters as input.
- * It will be easy enough to translate entries from an alarm.log file to
- * NRDP if real-time NRDP alarming is not enabled.
- *
- * For Nagios integration, the alarmTypes should all match "service names"
- * configured in the receiving Nagios server. Also, the alarm state will
- * be limited to the 4 values defined by Nagios:
- * 0 = OK, 1 = Warning, 2 = Critical, 3 = Unknown
- *
