# Subject	: To send DFM-alarm to Nagios `logger` into messages file, for Nagios(NAOMI) monitoring using logfile-encapsulator. And into directory for NaCl-PassiveCheck
#(0.2)	: Added CI_EXCL (CI=DFM_HOST_NAME)
#(0.3)	: Added DFMNAME, DFMTYPE
#(0.4)	: Mod DFM_-var's
#(0.5)	: Added dfm-inform
#(0.6)	: Changed name (from dfm_alarm2logger.sh) to dfm_alert2logger.sh, change log-dest
#(0.7)	: Mod `hostname` -> DFM + grep -v ':ok'|tee -a ${LOG}
#(0.8)  : LOG -> ${PGM}, ALERTLOG added
#(0.9)	: Mod. Added 2Nagios-PassiveCheck
#(0.1)	: Changed name from dfm_alert2logger.sh to dfm-alarm2nagios.sh
#(0.2)	: Added MAIL
