Zabbix_get with JMX issue

[isurugiu]

Hi all I have this issue:

I am getting

zabbix_get -slocalhost -kjmx[java.lang:type=Threading, ThreadCount]
ZBX_NOTSUPPORTED


However in the web interface everything is being reported fine. Is there a special way zabbix_get is to be used in conjunction with JMX?

Hi,

Zabbix_get can be used only with agent interface items and not with JMX.

Thank you Ingus,

So is it there like an easy way to test the JMX item definition/syntax?

Zbx_notsupported

Is there a path to troubleshoot ZBX_NOTSUPPORTED and Not Supported messages when defining or using zabbix_get for Items?

Additionally is there a way to test calculated items?

Hi Iulian,

Zabbix_get can only be used for getting data from items which are processed by Zabbix agent. JMX items are processed by Zabbix Java gateway so you cannot use zabbix_get here. As of now I cannot think of any easy ways to test JMX keys for syntax.

Which version of Zabbix server are you using? In 2.4 it gives you pretty detailed information why the item is not supported. And depending on that information you can then continue.

If you get ZBX_NOTSUPPORTED with zabbix_get then in most cases there is a syntax error in key or some permission issues. To troubleshoot it you can switch the agent in DebugLevel=4 and then see the zabbix_agentd.log file what exact messages does the system return to specific requests.

Calculated items are processed for already collected other items. I prefer to test them in web frontend. They will become not supported again because of syntax errors in formula or maybe simply because there is no data to process in the other items used in the calculated formula.

Create some simple dummy items and some calculated ones to see how you can build more complicated calculations around your items.

Best Regards,
Ingus
