Hello

zabbix is now running and i install a zabbix client on windows. Windows reports data perfectly. But i have a problem to connect SNMP Devices.

Switches, Firewall, ... @ the webinterface i see this message "Error doing snmp_open()"

in zabbix server log file i found this

This is similar to mine, I'm running 1.6.2 on CentOS 5.2 and using SNMP exclusively except for the ping checks. I hate to ask about the simple things but have you tried running snmpwalk against one of the devices you're getting the error message about? And, are you sure the community string is correct? For example, if you're looking at a switch or router and it has an ACL on it you might not be able to get to it until you change the ACL.

Again, I hope I'm not insulting you by asking the easy questions first, if so, I'm sorry...

Try this from the zabbix machine:
snmpwalk -v1 -c<community string> <name or ip address>
and see if you get a response. If that works, we'll go from there. If not, you don't have access to snmp on that device.

Good luck, post back with what you find.

i have now install a second server with ubuntu and zabbix for check the snmp function is ready on my switch.

on both server the i have a long result list with "snmpwalk -v 2c -c public 192.168.22.50"

SNMPv2-MIB::sysDescr.0 = STRING: 24-Port 10/100/1000 Gigabit Switch w/WebView
SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.3955.6.1.2024.1
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (30681858) 3 days, 13:13:38.58
SNMPv2-MIB::sysContact.0 = STRING:
SNMPv2-MIB::sysName.0 = STRING:
SNMPv2-MIB::sysLocation.0 = STRING:
SNMPv2-MIB::sysServices.0 = INTEGER: 2
SNMPv2-MIB::sysORLastChange.0 = Timeticks: (0) 0:00:00.00
SNMPv2-MIB::sysORID.1 = OID: SNMPv2-SMI::enterprises.89.73
SNMPv2-MIB::sysORDescr.1 = STRING: RS capabilities
SNMPv2-MIB::sysORUpTime.1 = Timeticks: (0) 0:00:00.00

in zabbix the result of snmp is on ubuntu
OID [1.3.6.1.2.1.5.13.0] value has unknow type [0x80] -> i think this is a good message...
on centos
Error doing snmp_open()

Ok, we're making progress. Here's what I do when I want to set up a device. I do the snmpwalk and redirect it to a file. Then I look in that file to find the parameters I want to monitor. You can do the same thing by taking the part you just sent, for example, if you want to check that system description field you would do this:

snmpget -v1 -c public <ipaddress> sysDescr.0

and see if you get a response. If so, you can put sysDescr.0 in the snmp oid field when you set it up under Items. You don't have to get the numbers for most OIDs and it's easier to read. You can do the same thing by putting the numbers for the OID in place of sysDescr.0 but the English version is easier to deal with than a long string of numbers and dots.

Here's how I do it on a router:

snmpget -v1 -c <community_string> <ipaddress> ifInOctets.2
and I get this:
ifInOctets.2 = Counter32: 193391087


If that doesn't work, post a screen shot of your Item setup and we'll go from there.

Good luck!
