SNMP Traps shows <UNKNOWN>

[sharafy]

Hi,

I setup Zabbix snmp trap and host name shows up as <UNKNOWN> under "Latest Data"

# snmptrap -Ci -v 2c -c public localhost "" "NET-SNMP-MIB::netSnmpExperimental" NET-SNMP-MIB::netSnmpExperimental s "test15"

Outcome:

2012.Oct.15 17:22:31	<UNKNOWN> "test15" NET-SNMP-MIB::netSnmpExperimental

I have created a host called snmptraps with ip 127.0.0.1 and assigned the following item to the host:

Name: snmptraps
Type: Zabbix Trapper
Key: snmptraps
Type of information: Character

Any snmp traps that I sent to Zabbix shows up as <UNKNOWN>. Can someone help me with this please?

Zabbix Version: 2.0.3

snmptrap.sh:

ZABBIX_SERVER="localhost";
ZABBIX_PORT="10051";

ZABBIX_SENDER="/usr/local/bin/zabbix_sender";

KEY="snmptraps";
HOST="snmptraps";

# END OF CONFIGURATION

read hostname
read ip
read uptime
read oid
read address
read community
read enterprise

oid=`echo $oid|cut -f2 -d' '`
address=`echo $address|cut -f2- -d' '`
community=`echo $community|cut -f2 -d' '`
enterprise=`echo $enterprise|cut -f2 -d' '`

oid=`echo $oid|cut -f11 -d'.'`
community=`echo $community|cut -f2 -d'"'`

str="$hostname $address $community $enterprise $oid"

$ZABBIX_SENDER -z $ZABBIX_SERVER -p $ZABBIX_PORT -s $HOST -k $KEY -o "$str"

Thanks.

It seems that I was starting the snmptrapd incorrectly.

I had to start snmptrapd with -n flag to avoid doing a reverse lookup on received traps and now I get the actual IP instead of <UNKNOWN>.

I'm running Net-SNMP 5.7.1
