No data in SNMP

[jandresaedo]

Hello Guys,
I have worked with zabbix 3.2.7 and my target now is the UPS. I taked a generic xml template and I adpapted it for the Kolff UPS. I attached the xml template in this post.

I tested the snmp OId mibs with snmpwalk, for example to take the UPS Load:

# snmpwalk -c public -v 2c 10.10.0.65 .1.3.6.1.2.1.33.1.4.4.1.5
SNMPv2-SMI::mib-2.33.1.4.4.1.5.1 = INTEGER: 18

The response looks good, the current CPU load is 18%.

So, my problem is when I try get this result in zabbix, because I don't recieve data, the template's configuration is in the img in attached images.

I don't have idea why I didn't recieve data from UPS, any help I'll would appreciate it.

Thanks.

Hi jandresaedo,
what zabbix server logs (/var/log/zabbix/zabbix_server.log) are saying about this? Any error ? Is there any other host which is monitored via SNMP and it works fine or problem affects all hosts ?

Hello Aleksejs
I found some errors:

upsBatteryStatus" became not supported: SNMP error: (noSuchName) There is no such variable name in this MIB.
upsBatteryTemperature" became not supported: SNMP error: (noSuchName) There is no such variable name in this MIB.
upsBatteryVoltage" became not supported: SNMP error: (noSuchName) There is no such variable name in this MIB.

I deleted the Template and I created a new Item:

Type:            SNMPV2Agent
Key:              .1.3.6.1.2.1.33.1.2.7
SNMP OID:  .1.3.6.1.2.1.33.1.2.7
SNMP:         Public

The status is enabled. But I have an error with this Item:

 item "ups:.1.3.6.1.2.1.33.1.2.7" became not supported: No Such Instance currently exists at this OID

And again, the same in snmpwalk from this server:

# snmpwalk -c public -v 2c 10.10.0.65 .1.3.6.1.2.1.33.1.2.7
SNMPv2-SMI::mib-2.33.1.2.7.0 = INTEGER: 22

Thanks.

Actually using just blank snmpwalk request you can get the all list of mibs:

snmpwalk -v 2c -c public 10.10.0.65

however some of your MIBs need to be translated, so use this manual to add MIBs (http://net-snmp.sourceforge.net/wiki...d_loading_MIBS) to you SNMP folder.

Yes, understood about snmpwalk -v 2c -c public 10.10.0.65 and its answer, but I don't understand why zabbix can't give me the same answer,

I have created the Item with the same Mibs, why snmpwalk answer and zabbix not.


Thanks.

You're not poking the right OID in Zabbix. You did a walk on MIB-2.33.1.4.4.1.5, and the walk responded with MIB-2.33.1.4.4.1.5.1 .You need to add a '.1' to the end of the OID Key becuse Zabbix is doing a simple snmpget on the OID, not a walk.

This is the same issue as with your post on the 4th: you need to add a '.0' to the end of your OID in Zabbix.


Where you're going wrong is you are asking for a item without specifying a specific interface on that item. Think of it this way: you have a switch with 48 ports on it. Each port will have access to the same SNMP data (we'll work with IF-MIB::ifSpeed), but the only way to know WHICH port is to specify it. So doing a walk for IF-MIB::ifSpeed will return with 48 responses, but doing a simple get will respond with an error because the switch does not know which port you are wanting information on.
