Unsupported item key -discover rules

[ggggsc]

my es version: 6.6.5
my zabbix version: 4.0.4

deployed follow the instruction,but the discovery rule doesn't work.
I'm sure that there's no x-pack active, no user&password needed
How can i deal with this?

@ggggsc Hi. Did you restart zabbix-agent after the extension was installed? Unsupported item key is a result in two problems:

• zabbix-agent didn't restart after installation
• misconfiguration of zabbix-agent when it doesn't know about new items installed by https://github.com/zarplata/zabbix-agent-extension-elasticsearch/blob/master/zabbix-agent-extension-elasticsearch.conf. Check the config of zabbix-agent and be shure that config contains Include parameter and this include path contains file zabbix-agent-extension-elasticsearch.conf
