apparently, you are using some library to access the zabbix api. please show exact json sent and received.
also, in which version that same json worked the way you expect it to ?
hey,
yes using the zabbix php api class.
i've just used curl to get the same information and its displaying as above.
grabbing the auth
curl -i -X POST -H 'Content-type:application/json' -d '{"jsonrpc":"2.0","method":"user.authenticate","params":
,"auth":null,"id":0}' http://localhost/zabbix/api_jsonrpc.php
grabbing the data
curl -i -X POST -H 'Content-type:application/json' -d '{"jsonrpc":"2.0","method":"host.get","params":{"output":"extend","selectInventory":"true","filter":{"host":"servername"}},"auth":"AUTHKEYPASTEDINHERE","id":1}' http://localhost/zabbix/api_jsonrpc.php
Response
{"jsonrpc":"2.0","result":[{"templates":[
],"maintenances":[],"hostid":"10109","proxy_hostid":"0","host":"servername","status":"0","disable_until":"0","error":"","available":"1","errors_from":"0","lastaccess":"0","ipmi_authtype":"-1","ipmi_privilege":"2","ipmi_username":"","ipmi_password":"","ipmi_disable_until":"0","ipmi_available":"0","snmp_disable_until":"0","snmp_available":"0","maintenanceid":"0","maintenance_status":"0","maintenance_type":"0","maintenance_from":"0","ipmi_errors_from":"0","snmp_errors_from":"0","ipmi_error":"","snmp_error":"","jmx_disable_until":"0","jmx_available":"0","jmx_errors_from":"0","jmx_error":"","name":"servername","flags":"0","inventory":{"hostid":"10109"}}],"id":1}
Thanks
I have exactly the same problem in 2.1.0 Alpha and 2.2.0. It only returns hostid in the inventory field.
hey, thanks for updating. good to know its not just me.
i can confirm this was working in 2.06/2.09
i'm still running with 2.20 its much better performance wise but would like the get the inventory details back if possible.
@richlv: Do you need any more information from our site to solve this issue in 2.2.1?
i don't think selectInventory should be a literal string "true"... try setting it to '1'
i just tried with '1' and double checked the documentation
"selectInventory boolean/array Return the host inventory from the host in the inventory property.
Possible values are true to return all of the data, or an array of property names to return only specific properties"
thanks
Same problem with 1 instead of true. Thanks for fixing this 
We see this same problem in 2.0.8 but it looks like this has yet to be resolved in any version? Or is there a version we can upgrade to that resolves this issue? Thanks.
I can confirm this is an issue as well in latest 2.2.2. Would love to see this fixed.
Mike,
A workaround I found is the following:
curl -i -X POST -H 'Content-type:application/json' -d '{"jsonrpc":"2.0","method":"host.get","params":{"output":"extend","selectInventory":"extend","filter":{"host":"servername"}},"auth":"AUTHKEYPASTEDINHERE","id":1}' http://localhost/zabbix/api_jsonrpc.php
ie. use extend rather than true or 1 for selectInventory. Also works in PhpZabbixAPI:
'selectInventory' => 'extend'
While you won't be able to filter the out (I don't think) at least you will get everything you need.
The behavior of selectInventory has been changed in ZBXNEXT-1491, but hasn't been documented. It now behaves like all other subselects, that is, accepts either "extend" or an array of properties.
I've updated the API docs:
