snmptrapd problems

[cpszx]

Hi,

sorry for the duplicate posting in the sourceforge forum, i thought i was on this browser window.

Great product, which will be better with some of the wishlist items on the next release
Also, might have some constructive suggestions after i get all the features working.

i am having trouble with the snmptrapd, snmptrap.sh and zabbix_trapperd configuration.

I found this from you on a previous thread :-
=====
Here is small checklist:

1. zabbix_tarpperd is running and accepts connections from local host
2. You have defined a special host and item for trapping
3. Same host and key (Step2) should be configured in snmptrapd.conf
4. Make sure that the script is called when you receive a trap. Add line "touch /tmp/something" to do this.
5. Define LogFile in zabbix_trapperd.conf, check it after receiving trap.

Regards,
Alexei

but am still having trouble.
1. OK
2. not sure if this is correct or not, no manual info on zabbix_trapper items....
using an existing host entry
item=zabbix trapper
key=snmptrap.0
type=character
allowed hosts=trap sender ip
3. as far as i can tell, subject to 2
but have also tried moving HOST= to AFTER the address is determined, and set there.
4. OK
5. Got line:"I:snmptrap.0:172.16.100.223 "I 172.16.100.223 "public"
followed by db insert fail.

not convinced am getting the right data out of the trap info either.

Regards,
Craig

ZABBIX failed to insert record into database because of quotes in the trap message. I'm not sure where the quote characters comes from.

Please add this line to the very end of snmptrap.sh:

echo $ZABBIX_SENDER $ZABBIX_SERVER $ZABBIX_PORT $HOST:$KEY "$str" >/tmp/snmptrap.log

Generate a trap and show snmptrap.log.

Hi Alexei,

here is the output from all of the log files, regarding me changing the time on a device.

the first part is what snmptrapd logs in /var/log/messages,
the second part is from your debug output in the last message,
the third part is from the zabbix_trapperd.log

I am on the debug trail this morning
Regards,
Craig

ok, snmp v2 issues?

ok,
i have found why i was not logging the traps to the database.
need to match the HOST value with the host name properly. i was too used to using the ip address.
set up a generic snmptrap host, like you suggest and it was logging traps...
So, once i get the dns resolution setup properly, i can probably trap to individual host entries in the database, rather than a generic one.

BUT, it seems the trap format might be different ? I have output the read variables for debug:

hostname==172.16.100.223
oid==SNMPv2-MIB::snmpTrapOID.0 SNMPv2-SMI::enterprises.11.2.3.7.11.23.0.2
ip==172.16.100.223
address==SNMPv2-SMI::mib-2.16.9.1.1.2.176 "I 10/03/04 10:47:56 mgr: changing time"
community==SNMP-COMMUNITY-MIB::snmpTrapAddress.0 172.16.100.223
enterprise==SNMP-COMMUNITY-MIB::snmpTrapCommunity.0 "public"

I am monitoring an HP4108 switch.
