SNMP Issue

[aaresmi]

Hi guys,

I've the next issue i dont know what is wrong.

From snmpwalk all works fine:

snmpwalk -v2c -c public 195.233.178.97:9002 BEA-WEBLOGIC-MIB::serverRuntimeState
BEA-WEBLOGIC-MIB::serverRuntimeState.".▒^j?nβ▒▒▒.▒▒*." = STRING: "RUNNING"
BEA-WEBLOGIC-MIB::serverRuntimeState."}▒▒Kg▒4..m▒zm<▒▒" = STRING: "RUNNING"
BEA-WEBLOGIC-MIB::serverRuntimeState."..K▒bk▒ ▒;.▒W▒>." = STRING: "RUNNING"

But from zabbix always get "No Such Object available on this agent at this OID"

The Item configuration is:
Name: prueba
Type: SNMPv2 agent
Key: prueba
Host interface: 195.233.178.97:9002
SNMP OID: BEA-WEBLOGIC-MIB::serverRuntimeState
SNMP community: public
Port: 9002
Type of information: Text

Update interval (in sec): 10
History storage period (in days): 90

please, anyone knows what i'm doing wrong?

I did a tcpdump at dst server and see the next:

+.......q.h.<..H...a.F#*.8..0......public.!..s.Ms. .....0.0.. => This was the zabbix request. This not work
+.......q.h.<..H...a."#*.8..0......public.!..pI... .....0.0.. => This was the snmpwalk request. This work

of course, the SNMP OID is the same in both request (serverRuntimeState // snmpwalk -v2c -c public 195.233.178.97:9002 serverRuntimeState)

any clue bros?

SNMP Problem

I also have a similar problem with SNMP.

I want to monitor the OSPF neighbor status, from the snmp walk I can get the information, but not with zabbix.

Follow the snmpwalk query.

root@Network-Service-Server:~# snmpwalk -c alexlab -v2c 192.168.10.1:161 1.3.6.1.2.1.14.10.1.6
iso.3.6.1.2.1.14.10.1.6.192.168.12.2.0 = INTEGER: 8

Zabbix says it does support the OID, but as we see it is not a proprietary one.

The Cisco Router version follows

R2#sh ver
Cisco IOS Software, 3600 Software (C3660-TELCOENTK9-M), Version 12.4(13b), RELEASE SOFTWARE (fc3)

It is an old Cisco IOS.

I see what is my issue and if i undestand well seem to be an zabbix limitation but maybe someone that knows more than me can confirm it.

the weblogic snmp is return a 128 (Decimal) type,

In zbx_snmp_set_result() type:128 value_type:4 data_type:0

128 type is 0x80 (as Hex). This type of data in snmp library is
#define ASN_CONTEXT ((u_char)0x80)

In the zabbix code they check for this kind of types (see at zabbix_server/poller/checks_snmp.c) :
ASN_OCTET_STR
ASN_OBJECT_ID
ASN_UINTEGER
ASN_COUNTER
ASN_UNSIGNED64
ASN_TIMETICKS
ASN_GAUGE
ASN_COUNTER64
ASN_INTEGER
ASN_INTEGER64
ASN_FLOAT
ASN_DOUBLE
ASN_IPADDRESS

if not is any of this types:

SET_MSG_RESULT(result, zbx_get_snmp_type_error(var->type));
ret = NOTSUPPORTED;
