      Description

      I have problem with query Oracle database (12c) from zabbix 3.2 (installed on Centos 7 + zabbix from rpm packages).
      I also installed oracle instant-client and ODBC package.

      I need to query database with different queries. Now I created item "Database monitor" with simple query.
      In item page is described now as "Not supported".

      [root@zabbix3 ~]# cat /etc/odbc.ini
      [<DATABASE NAME>]
      Driver=Oracle
      ServerName=//aa.bb.cc.dd:1521/<service name>

      DSN=<DATABASE NAME>
      Port=1521
      #UserID=MY_DATABASE_USER>
      #Password=DATABASE_USER_PASSWORD
      

      I created odbc connection and it's fully working from OS commandline.
      Also manually and as command.

      Fired up manually - works.

      – I can also get that data from shell (create a script?), but this is not acceptable solution for me.

      I tried:

      • add/remove user + password to odbc configuration.
      • use password (or without it when added to odbc) in zabbix configuration
      • change type of data gathered from zabbix to text / log
      • change number precision (float / usigned)

      ... all without success. As I see, this is a problem with connection to database.
      It's strange because it's work without any problem from linux commandline (in both version with password in odbc or without it (isql -v <DATABASE LINK>)

      Any help?

      One note : from time to time this connection message from database in log (Received value [....]) are changed from one to another - like [?G?t] or [XSWISS] [?] [?H?t] - like random value ... :/
