Based on this log, it seems that only two hosts are affected: "EUR-SYS_StDenis" and "INTUITY_AUDIX_Rouen". On those, these are not regular items that fail with this error, but LLD rules with key "discovery[{#SNMPVALUE},HOST-RESOURCES-MIB::hrStorageDescr]". Could you please check their configuration?

Comment by salim nouh [ 2016 Dec 05 ]

Thank you Aleksandrs Saveljevs for your analyze;

If i understood, the problem is on LLD rules and we should check that.

I asked if you can explain us for how check that please ? else i talk to our ingineer about that.

Thank you very much.

Best regards
Salim

Comment by Aleksandrs Saveljevs [ 2016 Dec 05 ]

Doing the same screenshots as you posted before for these LLD rules and host macros could be enough.

Comment by salim nouh [ 2017 Jan 10 ]

Hello Aleksandrs ;

I hope you are fine ;

1)
I attached screenshot of Zabbix config as demanded;

2)

Can I ask you help about Mysql on ZABBIX server please ?

Our customer has made a security scan and found a faille on port 3306 on MYSQL and want to correct that.

ZABBIX and Mysql ( Database ) was installed on the same server and we have only one server ZABBIX.

Can you please confirmed us if we can block this port please ? if we can do that, we can have process using ZABBIX Web Page ?

Thank you very much for your Help.

Best regards
Salim

Comment by salim nouh [ 2017 Jan 10 ]

I ask if you can check config using a remote session please using WebEx.

I 'm available.

Thank you for your Help.

Comment by Pedro Paulo Silva Gonçalves [ 2017 Feb 17 ]

Hi all,

I'm having the same problem, I'm using Zabbix server 3.2 + CentOS 7
I have a disk discovery by snmp, for windows and linux, as I'm not running.
The LLD and regular expression settings are correct, but I can not seem to collect information from any assets that use this LLD.
When I shoot the snmpwwalk it brings the result normally.

can anybody help me?

I removed this information from the log as an example.
