Problem pushing log from logstash to zabbix

Hello there,

I'm trying send log from logstash to zabbix but i face a problem i can't solve.

so these are my conf files :

Input :

input {
  udp {
    port => 514
    type => "syslog"

output :

output {
        zabbix {
                zabbix_server_host => "localhost"
                zabbix_host => "host"
                zabbix_key => "[@metadata][zabbix_key]"
                zabbix_value => "host"
        elasticsearch {
                hosts => ["localhost:9200"]

EDIT : zabbix_value => "message" but the problem is still the same

filter : ATM (for testing) i just want to push everything from logstash to zabbix so i added this line at the bottom of the file

        mutate {
                add_field => {"[@metadata][zabbix_key]" => "logstash_syslog" }

On zabbix i set up a zabbix trapepr with the same key and when i restart every services i have those log :

{:timestamp=>"2016-07-19T17:11:00.552000+0200", :message=>"Zabbix server at responded atypically.", :returned_data=>"ZBX_NOTSUPPORTED\x00Invalid item key format.", :level=>:error}

{:timestamp=>"2016-07-19T17:11:00.552000+0200", :message=>"Failed to send event to Zabbix", :zabbix_response=>"ZBX_NOTSUPPORTED\x00Invalid item key format.",

Do you have any idea how to fix this ?

Thanks for reading,


Without some debug logs from Logstash, I won't be able to help as quickly. It seems that something isn't being captured correctly.

What version of Zabbix? What version of Logstash? What version of the Logstash zabbix output plugin?
