SNMP_Community and OIDs in zabbix 3.0

[yngvith]

Hi I've just installed zabbix 3.0.
it as worked very well I think.
I've notices some problems though regarding SNMP devices.
I did create a discovery rule as in zabbix 2.4 and a particular test device was consequently discovered as aspected. Very good :-)
But when linking templates and gathering data, I get no data.
I did this as in zabbix 2.4 but now it does'nt work. I'm trying to find what has changed regarding i.e. SNMP_Commnunity string etc between those versions 2.4 and 3.0 .
Any good input from you, that could explain my troubles now?
this is from the log file,
/var/log/zabbix/zabbix_server.log

Hi,

Do you have the MIB on your Zabbix 3.0 server?
Can you show us your template?

SNMP_Community and OIDs in zabbix 3.0

hi
I used download-mibs to get them.
and you can see here the number of mib files downloaded:

root@zabbix1:/# ls -ltr /var/lib/mibs/ietf/ | wc -l
301
root@zabbix1:/#
root@zabbix1:/# ls -ltr /var/lib/mibs/iana/ | wc -l
16

Templates for this device are:
Tempate SNMP Device
Template Cisco 7200

hi, I can easily snmpwalk this device.
In fact I get no errors when doing snmpwalk with cmd on the zabbix server:


root@zabbix1:/# snmpwalk -v2c -c XXXX lab-7201 SNMPv2-MIB::sysName.0
SNMPv2-MIB::sysName.0 = STRING: lab-7201.ipnet.siminn.is

SNMPv2-SMI::mib-2.47.1.1.1.1.7.47 = STRING: "+12.15 V Voltage 0"


I did put the correct community string in the zabbix configuration.

SNMP_Community and OIDs in zabbix 3.0'

But I get errors in the zabbix server log file
/var/log/zabbix/zabbix_server.log

Errors like this one:

ciscoMemoryPoolName" became not supported: Invalid SNMP OID: pairs of macro and OID are expected

[yngvith]

SNMP_Community and OIDs in zabbix 3.0'

Also, when I do this in zabbix GUI :

Configuration->Hosts->Discovery ( i.e. for this device lab-7201)

There are 11 discovery rules in this category, with the 'key' for each one like this:
ospfNbrIpAddr
ospfIfIpAddress
ifDescr
cpmCPUTotalPhysicalIndex
ciscoMemoryPoolName
ciscoFlashDeviceDescr
ciscoEnvMonVoltageStatusDescr
ciscoEnvMonTemperatureStatusDescr
ciscoEnvMonSupplyStatusDescr
ciscoEnvMonFanStatusDescr
bgpPeerIdentifier

the 'type' parameter for every trigger is SNMPv2 agent
The 'status' of every trigger is 'not supported' except for the 'ifDescr'

hi, Yngvi,

Zabbix has changed SNMP OID discovery in 3.0. You can refer to https://www.zabbix.com/documentation...y_of_snmp_oids for reference.

For example, if you want to discover fans, you need to set SNMP OID to "discovery[{#SNMPVALUE},1.3.6.1.4.1.9.9.13.1.4.1.3]" in your discovery rules instead of "1.3.6.1.4.1.9.9.13.1.4.1.3".

Hope it helps.

SNMP_Community and OIDs in zabbix 3.0

Well, yes this is exactly correct!
So I've gone through the Discovery Configuration for severarl SNMP templates and done this change. Aftewards it works very well.
Thanks a lot for your help :-) You have just saved the day!!!

BTW do you know if there are more changes which have to be done for SNMP monitoring i.e. graphs or triggers?
best regards
Yngvi

[buzzerbeater]

As far as I have tested, the graphs and triggers work well.
