Enabling SNMP alerts

[Satyanarayana Jampa]

Hi,
                I am using Ambari 2.2 and I would like to enable the SNMP 
alerts.
                For  enabling the alerts I followed the below link:
                                
https://community.hortonworks.com/articles/74370/snmp-alert.html
                The "snmp_mib_script.sh" has snmptrap command, which take 
localhost as the "HOST" parameter as below:
Can this "Host" parameter be taken from the Ambari "Edit Notification" screen, 
just like the alert state, alertname etc?


HOST=localhost
COMMUNITY=public

STATE=0
if [ $4 == "OK" ]; then
  STATE=0
elif [ $4 == "UNKNOWN" ]; then
  STATE=1
elif [ $4 == "WARNING" ]; then
  STATE=2
elif [ $4 == "CRITICAL" ]; then
  STATE=3
fi

/usr/bin/snmptrap -v 2c -c $COMMUNITY $HOST '' 
APACHE-AMBARI-MIB::apacheAmbariAlert alertDefinitionName s "$1" alertName s 
"$2" alertText s "$5" alertState i $STATE alertService s "$3"

Thanks,
Satya.
