I'm trying to send keys/values from Logstash to Zabbix with logstash-output-zabbix and after trying different config options I stopped at this error "Zabbix server at [...] rejected all items sent." if I use zabbix_sender from my Logstash server I can send the value to Zabbix. My Zabbix version is 3.2.6 and Logstash 5.5.2.
Searching through this forums, I have seen a topic similar to my problem (Logstash output zabbix) but it's closed and I didn't see a solution. So is there a known problem between Zabbix 3.2 and Logstash?
