Zabbix doesn't query hosts via SNMP

[Leonidimus]

Hi folks,
I've migrated from version 1.1.4 to 1.4.2. MySQL DB conversion went OK, Zabbix sources compilation completed without errors. But, I'm having a serious issue - all SNMP items (both v1/v2) are not queued by Zabbix.

1. In the frontend (items.php) I see for all SNMP items: Status = Not supported, Error = SNMP error [1]
2. In the zabbix_server.log I see the following repeating errors:
   

    14505:20070918:055522 Starting zabbix_server. ZABBIX 1.4.2.

3. Unsurprisingly, tcpdump doesn't catch any SNMP packets from Zabbix
4. I can get SNMP info from all these hosts by snmpget using OIDs specified in Zabbix items
5. NET-SNMP version: 5.4.1

Any idea how to fix it? Please gimme a helping hand somebody!

I believe compilation was OK, since configure script didn't show any errors:

memAvailSwap0 doesn't looks like an oid
try it with the .1.1.3.. syntax..

[Leonidimus]

memAvailSwap0 doesn't looks like an oid

You're right, it's a key
I dunno why, but Zabbix writes key_ names but not snmp_oid's in the log.

mysql> select type,snmp_community,snmp_oid,snmp_port,description,key_,status,error from items where key_='memAvailSwap0' limit 25;
+------+----------------+------------------------------+-----------+--------------------------+---------------+--------+-----------------+
| type | snmp_community | snmp_oid                     | snmp_port | description              | key_          | status | error           |
+------+----------------+------------------------------+-----------+--------------------------+---------------+--------+-----------------+
... ... ...
|    4 | hrenvamm       | UCD-SNMP-MIB::memAvailSwap.0 |       161 | Memory: Swap (available) | memAvailSwap0 |      3 | SNMP error [1]  |

OIDs are all correct, they're working perfectly on the host with Zabbix 1.1.4 now. By the way, I've tried digital notation and got the same errors... Maybe, the problem is Zabbix 1.4.x is not compatible with NET-SNMP v. 5.4.1

[Leonidimus]

Heh....

It was a library incompatibility issue, as I thought. I recompiled Zabbix with old net-snmp v. 5.1.2 and voila:

 24058:20070920:062354 Parameter [cisco_C3750_Vlan1_Out] became supported by agent on host [SJCSAN01]
 24058:20070920:062354 Parameter [cisco_C3750_GE104_OutErrors] became supported by agent on host [SJCSAN01]
 24058:20070920:062354 Parameter [ac_2810_snmp_get_t1_13_alarm] became supported by agent on host [sjcts14_board-0]

Maybe someone want to ask why I used the latest net-snmp libs... I did it because Zabbix' configure script refused to complete installation with old libs, just like described in this thread. I fixed configure script by adding -lcurl at line 10534, as Areg advised and this allowed me to use the legacy net-snmp.

I Leonidimus, I think I have the same problem !

I'm a newbie in linux, so you decided to uninstall net-snmp 5.4.1 (make uninstall) and replace by net-snmp 5.1.2 ?
And you wrote "I recompiled Zabbix with old net-snmp v. 5.1.2" so you uninstall zabbix (make uninstall) and then redo a configure command with the new path of your net-snmp 5.2.1 ?

To conclude the problem is net-snmp 5.4.1 with zabbix 1.4.2 ?


Thank's in advance !


P.S: are you french ?

[Leonidimus]

Yeap,

I uninstalled net-snmp 5.4.1, installed the old 5.1.2, patched configure script, run it and did make install for Zabbix again. That's it.

Non, je ne suis pas le Français But, some relatives say my great grandma was a French.

[psedo]

Thanks !

Thanks it worked !
I decided to redo a complete install, and for once I installed net-snmp-5.1.2 packages (devel, utils, perl...), and no pacth for configure is needed !

Your french is good ! Better than my english !
