SNMP error in packet. Reason: (noSuchName) There is no such variable name in this MIB

[den_crane]

In Zabbix Log:
015399:20070913:164240 SNMP error in packet. Reason: (noSuchName) There is no such variable name in this MIB.

015399:20070913:164240 SNMP error [(noSuchName) There is no such variable name in this MIB.]
015390:20070913:164324 SNMP error in packet. Reason: (noSuchName) There is no such variable name in this MIB.

015390:20070913:164324 SNMP error [(noSuchName) There is no such variable name in this MIB.]
015361:20070913:164345 SNMP error in packet. Reason: (noSuchName) There is no such variable name in this MIB.

015361:20070913:164345 SNMP error [(noSuchName) There is no such variable name in this MIB.]

How find what item is wrong? (I use only numeric OIDs)

SELECT count(*) FROM `items` where `error` <>'';
count(*)
0

zabbix 1.1.7

What is the OID?
Have you tried to fetch the values using the 'snmpget' or 'snmpwalk' commands from the net-snmp tools?

In zabbix I have ~1000 SNMP items on 50 hosts, I don't know which item is wrong.

[den_crane]

Solution is:

SELECT *
FROM items
WHERE STATUS =3

Best Solution to this problem

The following code change to /src/zabbix_server/poller/checks_snmp.c will provide the needed info in the log file:

if (status == STAT_SUCCESS)
{
  zabbix_log( LOG_LEVEL_WARNING, "SNMP error in packet. <%s:%s> Reason: %s\n", item->host_ip, item->snmp_oid,
  snmp_errstring(response->errstat));
  if(response->errstat == SNMP_ERR_NOSUCHNAME)
   {
     zbx_snprintf(error,sizeof(error),"SNMP error <%s:%s> [%s]", item->host_ip, item->snmp_oid,
     snmp_errstring(response->errstat));

     zabbix_log( LOG_LEVEL_ERR, "%s", error);
     SET_MSG_RESULT(value, strdup(error));

     ret=NOTSUPPORTED;
   }
  else
   {
     zbx_snprintf(error,sizeof(error),"SNMP error <%s:%s> [%s]", item->host_ip, item->snmp_oid,
     snmp_errstring(response->errstat));

     zabbix_log( LOG_LEVEL_ERR, "%s", error);
     SET_MSG_RESULT(value, strdup(error));

     ret=NOTSUPPORTED;
  }
}

The only lines that are changed are the zbx_snprintf, with the <...> and parameters added (and the first zabbix_log().

This REALLY needs to be incorporated into the code base. The addition of the host name (ip) and oid will allow you to actually figure out the problem.

[ptietjens]

Agree

That addition to the code is badly needed. There are too many objects to be so vague about which item/trigger/etc is causing the problem!

[just2blue4u]

thanks for this patch!
I modified it even more :

zbx_snprintf(error,sizeof(error),"SNMP error at host <%s> for OID <%s> [%s]", item->host_ip, item->snmp_oid,
                                        snmp_errstring(response->errstat));

But this line in my log makes me a bit worrying:

netsnmp_assert pss->s_snmp_errno != (-11) failed snmp_api.c:3124 snmp_build()

What's that?

Just for my information:
Why is there the it-then-else determination?
I don't find any differense between then and else block...

[Alexei]

I believe this is a problem of underlying net-snmp library. You may try to use different version of net-snmp-dev.

[just2blue4u]

Damn, my version 5.3.1-15.fc6 ist the latest for my OS Fedora Core 6.

So i'll just ignore that error as it seems to be a non-critical one :-/


If someone knows how to make yum install a more recent version, let me know...

update re: SNMP error in packet. Reason: (noSuchName)

Zabbix 1.5.3 CentOS5-x64

Taking Alexei's suggestion, I upgraded net-snmp-[everything] from 5.3.1-19 to 5.3.1-24 and recompiled server but there is no change. Still getting loads of noSuchName errors. The patch for checks_snmp.c for 1.4.x worked great - then i upgraded to 1.5.3. Cannot apply these patches to 1.5.3 as the code is different and i'm not skilled enough to dissect it. A previous message made the very valid point that the patches should have made their way into a >1.4.x version. Can we have a patched checks_snmp.c with these mods? Should be a snip for a Zabbix developer!

thanks

PS: fc6 is stuck at 5.3.1-15.fc8.i386.rpm (see pbone), whereas fc9 is as cutting edge as it gets with 5.4.1-7.fc8.i386.rpm. If you need the very newest or a newer net-snmp for fc6, you'll have to compile from source. However, no other OS has net-snmp RPMs at v5.4.

[CeeEss]

D'oh. Found the section in snmp_checks.c that require the above edits and nothing has changed from 1.4.2 after all. Works great, too - a real timesaver. Zabbix, please patch snmp_checks.c for v1.6?

For what it is worth, I upgraded from net-snmp-devel-5.3.1-19.el5 to net-snmp-devel-5.3.1-24.el5 and the problem went away. (on RHEL5)

[alfiere]

I reup this thread since I'm experiencing the same error:

"SNMP error [(noSuchName) There is no such variable name in this MIB.]"


CentOS release 5.3 x86_64 (Final)

#rpm -qa|grep net-snmp
net-snmp-libs-5.3.2.2-5.el5
net-snmp-5.3.2.2-5.el5
net-snmp-devel-5.3.2.2-5.el5
net-snmp-utils-5.3.2.2-5.el5

ZABBIX 1.6.4

any tips?

snmpwalk and snmpget work without any problems.

Cheers,
Alf

Hey alfiere,

Possibly a bit late to help you, but thought I'd post in case it helps anyone else.

I was having the same problems as described:-
* Zabbix 1.6.5
* CentOS with up to date net-snmp
* OID's that worked fine with net-snmp (both snmpget and snmpwalk)
Zabbix gave an error of "SNMP error [(noSuchName) There is no such variable name in this MIB.]"

As it turns out it was a simple thing - my OID's had trailing spaces in the item definition (e.g. ".1.2.3.4.5 ") - once I'd removed them everything was OK.

I'd created the items through an XML import and accidentally included trailing spaces in the definition there (e.g. <snmp_oid>.1.3.6.1.4.1.15.2.1.2 </snmp_oid> and key=".1.3.6.1.4.1.15.1.1 ").
