Hi folks, i can't connect Zabbix server (monitoring tool) to Terracotta.

Versions
Zabbix 2.2.3
Zabbix-Java-Gateway 2.2.3
Terracotta Server Array: 3.7.5

Zabbix and Zabbix java gateway are remote.
Zabbix connect via JMX to servers, thanks to Zabbix-Java-Gateway in whose log:

I think Terracotta is well configured because I can run jconsole without problem via:
jconsole -J-Djava.class.path="/usr/local/terracotta/terracotta-3.7.5/lib/tc.jar:/usr/lib/jvm/java-7-oracle/lib/jconsole.jar"

I tried adding tc.jar to the java gateway classpath but nothing happens.
Firewall is properly configured

Any idea?

from that exception is sounds zabbix is configured to assume the terracotta jmx server speaks JRMP.

If you're inputting a jmx service url to zabbix you might want to try something like:

service:jmx:jmxmp://1.2.3.4:9520

Where 1.2.3.4 is your terracotta server. You might potentially also need the jmxremote_optional jar from our kit

good luck

Thanks for your answer Erik, it seems you're right
Someone file this kind of bug
