# Description   : Script to forward OCUM alerts to Nagios (to SDM)
#
#(0.9),170524
#(0.10),171102  : Mod some var's & Added SDM12.9 part. & changed name to ocum-alert2nagios-sdm.sh
#(0.11),171213  : Added HOSTNAME & chk for no empty grep
#(0.12),180227  : Added create_sdm-ticket.sh
#(0.13),180716  : Added sleep 1
#(0.14),180925  : Changed check on nlnaf10[67] -> CREATE SDM ticket
#(0.15),210421  : Changed for SNOW
#(0.16),210610  : Mod for OCUM @nlxfsd11
#(0.17),210624  : Mod. form nlxfsd11, added -s|--sev
