Items key_ case-(in)sensitivity

[sivy310]

Hi,

I observed that when I try to send some value using zabbix-sender, item key_ is case-sensitive:

$ zabbix_sender -z vplab2236 -s PWS_JMETER -k "PWS_JMETER.pmt-Master-Auth-1S-Functions_setup[tps]" -o "0.03325131342688036" -vv
zabbix_sender [26333]: DEBUG: answer [{"response":"success","info":"processed: 1; failed: 0; total: 1; seconds spent: 0.000054"}]
info from server: "processed: 1; failed: 0; total: 1; seconds spent: 0.000054"
sent: 1; skipped: 0; total: 1

$ zabbix_sender -z vplab2236 -s PWS_JMETER -k "PWS_JMETER.pmt-Master-Auth-1s-Functions_setup[tps]" -o "0.03325131342688036" -vv
zabbix_sender [26352]: DEBUG: answer [{"response":"success","info":"processed: 0; failed: 1; total: 1; seconds spent: 0.000057"}]
info from server: "processed: 0; failed: 1; total: 1; seconds spent: 0.000057"


However, when I try to create two different items in Zabbix (names as above) it looks like it's case-insensitive so I recieve error:

Is it known behaviour of both zabbix-sender and Zabbix?

What are you using as a database?
Is it a character code setting that can distinguish upper case letters and lower case letters?

ex. MariaDB

MariaDB [zabbix]> show variables like 'char%';
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | utf8                       |
| character_set_connection | utf8                       |
| character_set_database   | utf8                       |
| character_set_filesystem | binary                     |
| character_set_results    | utf8                       |
| character_set_server     | utf8                       |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)

MariaDB [zabbix]> show variables like 'collation%';
+----------------------+----------+
| Variable_name        | Value    |
+----------------------+----------+
| collation_connection | utf8_bin |
| collation_database   | utf8_bin |
| collation_server     | utf8_bin |
+----------------------+----------+
3 rows in set (0.00 sec)
