Zabbix not pulling Data from SNMP OID

[LukeAB93UK]

Hey Guys,

I have an interesting problem here on Zabbix Zabbix 6.0.9.

I am trying to pull this value from a Juniper SRX 320 router running JUNOS 21.3R1.9.



I can using the above command I can see the raw data and the router has SNMP configured as "read only" using udp on port 161 with an snmp community user to be able to poll the information.

Now we do employ Zabbix Proxies and the host that this proxy is on Centos.

When I click on "Get Value and Test" I am greeting with this error message.



I was wondering if there is something we missed or things we can check because I am starting to think the problem lays either with our Zabbix Server or Proxies so I am just wondering if there are things we should check because this data is just simply not coming through.

Try specifying the following OIDs.
1.3.6.1.2.1.10.94.1.1.5.1.2.550

1.3.6.1.2.1.10.94.1.1.5.1.2.550

Hey there.

I have also tried that as well with the same result.




I tried to pull the information on one of our Zabbix procies too with same results



Part of me is thinking our proxy is misconfigured but im now to this so not entire sure where to look if im being honest.

Pls try "snmpwalk yours_creditans -Ona 1.3.6.1.2.1.10.94.1.1.5.1" and show the output

Or just try the OID 1.3.6.1.2.1.10.94.1.1.5.1.2.550.0

Hello,

I am just getting this output.

Do you have some rules in Juniper so that community used isn't allowed to read those values? Can you read any information using that community from zabbix proxy?

Yes I am.

If I run snmpwalk I can pull data.

i have made a discovery.

I used SNMP walk on my Juniper Device and pulled the OID for the ADSL speed I am trying to monitor and Zabbix is still returning no such object at this OID


As you can see the OID I have been using is correct.

I randomly grabbed anorther OID from a different value I came across when doing an SNMP walk.

2) From www.juniper.net/documentation

What can I do if the MIB OID query is not responding?

There can be various reasons why the MIB OID query stops responding. One reason could be that the MIB itself is unresponsive. To verify that the MIB responds, use the show snmp mib walk | get MIB name | MIB OID command:

• If the MIB responds, the communication issue exists between the SNMP primary and SNMP agent. Possible reasons for this issue include network issues, an incorrect community configuration, an incorrect SNMP configuration, and so on.
• If the MIB does not respond, enable SNMP traceoptions to log PDUs and errors. All incoming and outgoing SNMP PDUs are logged. Check the traceoptions output to see if there are any errors.

If you continue to have problems with the MIB OID query, technical product support is available through the Juniper Networks Technical Assistance Center (JTAC).

Hello,

So I have made some progress. I have got the proxy to pull the string.



However even if I specify the ifIndex of the interface



or not



I am still getting "

• No Such Instance currently exists at this OID

I am legitimatey now at a total loss on how to get that string to dump that info into my Zabbix instance.

[Hamardaban]

The difference is that snmpwalk runs down the tree from the specified OID, while zabbix "uses" snmpget which requests the specified value.

From proxy try "snmpget yours_creditans -Ona yours_IP 1.3.6.1.2.1.10.94.1.1.5.1.2.550.0" and if you get a value, use exactly this OID in zabbix.

Hey there,

I ran that exactly from the proxy and I got this

snmpget <MyCommunityString> -Ona <MyIP> 1.3.6.1.2.1.10.94.1.1.5.1.2.550.0
snmpget: Invalid address (<MyCommunityString>) (Resource temporarily unavailable)

[LukeAB93UK]

I ran this command with -Ona I had to specify -v2c and -c

snmpget -v2c -c <MyCommunityString> -Ona <IP Address> 1.3.6.1.2.1.10.94.1.1.5.1.2.550.0
.1.3.6.1.2.1.10.94.1.1.5.1.2.550.0 = No Such Instance currently exists at this OID

Yet with an SNMP walk it shows the value

snmpwalk -v2c -c <MyCommunityString> <IP Address> .1.3.6.1.2.1.10.94.1.1.5.1.2
SNMPv2-SMI::transmission.94.1.1.5.1.2.550 = Gauge32: 8544000

Not sure if im doing or have done something wrong but I can pull the value 8544000 with walk but not with get.

[Hamardaban]

if you zabbix version gt 6.4 you can use new feature https://www.zabbix.com/documentation...snmp_oids_walk

[LukeAB93UK]

if you zabbix version gt 6.4 you can use new feature https://www.zabbix.com/documentation...snmp_oids_walk

And doing this would allow me to "walk" and get the value instead of get correct?
