SNMP in Zabbix 1.6

[tazzu]

Hi Guys,

I have a question for using SNMP in Zabbix 1.6 . It's the first time that i want to use snmp in Zabbix. I've already monitored performance Data with Zabbix 1.4 but that was with the zabbix agent.

So I've found several documentation about snmp in Zabbix. But I'm a little bit confused now (The most Threads or How-To are for 1.4). Can someone explain in short words how I can receive SNMP Traps with Zabbix 1.6? I've compiled zabbix with option --with-net-snmp .

For now, I only want to receive the traps (no active polling).

Regards

Tazzu

What I've done:

Copyed snmptrap.sh to /home/zabbix/zabbix-1.6/bin/snmptrap.sh
Config:

ZABBIX_SERVER="localhost";
ZABBIX_PORT="10050";
ZABBIX_SENDER="/usr/sbin/zabbix_sender";
KEY="snmptraps";
HOST="snmptraps";

snmpd.conf config:

TRAPDRUN=yes
outputOption efnQs
traphandle default /bin/bash /home/zabbix/zabbix-1.6/bin/snmptrap.sh


In Zabbix:

I've addet a host called snmptraps. For this host I've created an item "snmptraps" as an "ZABBIX trapper".

But I can't receive any traps when i use:

snmptrap -v1 -c public localhost .1.3.6.1.6.3.1.1.5.2 0 0 "" "" .1.3.6.1.4.1 s "hello"

What is wrong with my config?

EDIT:

I've found some errors in /var/log/net-snmpd.log:

NET-SNMP version 5.3.0.1
cannot open /proc/net/snmp6 ...


I've addet this to /etc/snmptrapd.conf:
TRAPDRUN=yes
traphandle default /bin/bash /home/zabbix/zabbix-1.6/bin/snmptrap.sh

I'm using Suse Linux Enterprise 10 (SLES 10)

Ok I've made some changes. Now my snmpd is working fine:

http://www.zabbix.com/forum/archive/index.php/t-2978.html

I've made some changes in snmptrap.sh so that I can see what happens:

# CONFIGURATION

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

ZABBIX_SENDER="/usr/sbin/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"
echo " " > /home/zabbix/zabbix-1.6/bin/test.log
echo $ZABBIX_SENDER "ZABBIX_SENDER" >> /home/zabbix/zabbix-1.6/bin/test.log
echo $ZABBIX_SERVER "ZABBIX_SERVER" >> /home/zabbix/zabbix-1.6/bin/test.log
echo $ZABBIX_PORT "ZABBIX_PORT" >> /home/zabbix/zabbix-1.6/bin/test.log
echo $HOST "HOST" >> /home/zabbix/zabbix-1.6/bin/test.log
echo $KEY "KEY" >> /home/zabbix/zabbix-1.6/bin/test.log
echo "$str" "str" >> /home/zabbix/zabbix-1.6/bin/test.log

#$ZABBIX_SENDER $ZABBIX_SERVER $ZABBIX_PORT $HOST $KEY $str"
echo $ZABBIX_SENDER $ZABBIX_SERVER $ZABBIX_PORT $HOST $KEY \'"$str"\' >> /home/zabbix/zabbix-1.6/bin/test.log
$ZABBIX_SENDER $ZABBIX_SERVER $ZABBIX_PORT $HOST $KEY \'"$str"\'

Then I executed:

snmptrap -v1 -c public localhost .1.3.6.1.6.3.1.1.5.2 0 0 "" "" .1.3.6.1.4.1 s "hello"

in test.log now:
/usr/sbin/zabbix_sender ZABBIX_SENDER
localhost ZABBIX_SERVER
10051 ZABBIX_PORT
snmptraps HOST
snmptraps KEY
localhost "hello" public SNMPv2-MIB::warmStart SNMPv2-MIB::coldStart str
/usr/sbin/zabbix_sender localhost 10051 snmptraps snmptraps 'localhost "hello" public SNMPv2-MIB::warmStart SNMPv2-MIB::coldStart'

So I've tryed to execute the sender manually:

/usr/sbin/zabbix_sender localhost 10051 snmptraps snmptraps 'localhost "hello" public SNMPv2-MIB::warmStart SNMPv2-MIB::coldStart'

Response:

usage: zabbix_sender [-Vhv] {[-zpsI] -ko | [-zpI] -i <file>} [-c <file>]

Now I'm a little bit confused... Anyone who can help?

It seems that I've got an old sender:

I've downloaded the newest Version of Zabbix 1.6 ! Maybe this will help people who have the same problems than me.

Snmptrap and zabbix_sender

Hello,

I try to receive some traps via Zabbix, and it's a total disaster. I'm on it since last week...

I followed two tutorials :
- in one hand, i added some lines in the file : snmptrapd.conf
TRAPDRUN = yes
outputOption efnQs
traphandle default /bin/bash /home/zabbix/bin/snmptrap.sh
- then, i edit the file "snmptrap.sh" and i defined Zabbix_sender patch and another things...
- finally i create host and item according to what i defined in "snmptrap.sh"


For testing the sending of trap, in the shell i write this :
snmptrapd -P -F "%02.2h:%02.2j TRAP %w.%q de %A\n"
and
snmptrap -v2c -c public 127.0.0.1 uptime trapoid .1.3.6 i 123
if i don't write "trapoid", this command doesn't work...


The result is :
14:43 TRAP 0.0 from 0.0.0.0
zabbix_sender [6581]: DEBUG: Answer [{
"response":"success",
"info";"Processed 1 Failed 0 Total 1 Seconds spent 0.102274"}]
Into from server : "Processed 1 Failed 0 Total 1 Seconds spent 0.102274"
sent : 1; skipped : 0; total : 1

it's seems to be OK but i received on Zabbix "localhost =" !! And, in a file test.log which returns the value of the string sent, i have :
(...)
localhost = str
/home/.../zabbix_sender localhost 10051 Server_Zabbix snmptraps 'localhost ='

Moreover, i try to use zabbix_sender and i had to use this command :
/home/.../zabbix_sender -z localhost -p 10051 -s Server_Zabbix -k snmptraps -o 'test'
to receive "test" on Zabbix web page (this works)


Anyone knows why i receive 'localhost =' in my string instead of 'localhost 123 public SNMPv2-SMI::dod' ??
Or why do i have TRAP 0.0 from 0.0.0.0 ??

A help will greatly appreciated....

Response:

usage: zabbix_sender [-Vhv] {[-zpsI] -ko | [-zpI] -i <file>} [-c <file>]

Now I'm a little bit confused... Anyone who can help?

change below line in "snmptrap.sh"

$ZABBIX_SENDER $ZABBIX_SERVER $ZABBIX_PORT $HOST $KEY \'"$str"\'

with this one & try.

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

Hope this will solve your problem..

my solution :

There was a difference between the librairies and headers used by the snmp i installed on my computer and what was written in yast... once I resolved this problem, the snmptrap worked.

thanks for yours helps

Is there a comprehensive tutorial in this somewhere? I´m new to Zabbix and I would like to use SNMP with it (I don´t want to install agents on the other windows servers and SNMP delivers all information I need. Thanks for an answer!
