Hello,

im having an issue with Zabbix JMX monitoring, maybe you can help me to troubleshoot this.

I have a Zabbix Server running with some Zabbix Proxies, in each instance we have Java Gateway component to monitor different JMX hosts

Zabbix version is the same Server or Proxies, 4.4.8. Solution is installed in different hosts with Red Hat Enterprise Linux 6.10 Santiago OS's.

We never had any issues with normal JMX items (rmi protocol) like service:jmx:rmi:///jndi/rmi://

But now we need to monitor a WildFly 21 server, is working fine if we connect to the Wildfly JMX using Jconsole tool from my windows laptop opening the Jconsole importing the wildfly jboss-client.jar class, running from cmd something like

Move into jconsole exe location

cd C:\Program Files (x86)\Java\jdk1.8.0_211\bin

Execute Jconsole

jconsole -J-Djava.class.path="C:\Program Files (x86)\Java\jdk1.8.0_211\lib\jconsole.jar;C:\jboss-client.jar"

It work ok using these two connection strings

service:jmx:remote+http://10.216.78.34:9990

service:jmx:http-remoting-jmx://10.216.78.34:9990

BUT!

If i test this from Zabbix. if i create an item in zabbix with any of those connection strings i got an error saying that the http protocol is not supported

in zabbix_java.log file i see this error

2022-01-18 09:26:24.563 [pool-1-thread-18] WARN  com.zabbix.gateway.SocketProcessor - error processing request, item "jmx["jboss.system:type=ServerInfo","AvailableProcessors"]" failed: Unsupported protocol: remote+http: service:jmx:remote+http://10.216.78.34:9990

Ive created the item with this JMX endpoint service:jmx:remote+http:///jndi/rmi://\{HOST.CONN}:{HOST.PORT}/jmxrmi, or similar strings.

I've tried doing the jar files thing that is showed here at Custom endpoint example with JBoss EAP 6.4 part
 https://www.zabbix.com/documentation/4.0/en/manual/config/items/itemtypes/jmx_monitoring

but didn't work, maybe is not the same, but i think i need to do something similar.

Not sure if you can help me with this. Thanks!
