Zabbix agent does not sending data - Unsupported item key #162
Description
Cannot fetch data from server with 2 attached directly disks from zabbix server.
Running perl discovery script itself on monitored node as a zabbix user returns data correctly
# sudo -u zabbix sudo /etc/zabbix/scripts/smartctl-disks-discovery.pl
{
"data":[
{
"{#DISKMODEL}":"SAMSUNG MZ7LM480HMHQ-00005",
"{#DISKSN}":"S2UJNX0M502684",
"{#DISKNAME}":"/dev/sda",
"{#DISKCMD}":"/dev/sda -d sat",
"{#SMART_ENABLED}":"1",
"{#DISKTYPE}":"1"
},
{
"{#DISKMODEL}":"SAMSUNG MZ7LM480HMHQ-00005",
