Nextcloud Template fails on XML

[Pitastic]

Hey there,

thanks for this great piece of software.

I am monitoring one of my hosts with a Nextcloud instance with the official Nextcloud Template on a dockered Zabbix 6.4. Most of the values are working great.

However the item

Nextcloud:Get server information

preprocesses an xml to jaon for all of its dependent items. For this item the error occurs, that Zabbix is not compiled with libxml2 support.

I double checked with

ldd /usr/sbin/zabbix_server | grep xml

(and …proxy) that there is libxml2 buildin. I can also test the item succesfully using zabbix server or one the proxys. But real checks always failing with the xml2 problem.

Am I missing something or is thisma bug?

Affer a while a found two bugs. One in the Template and one in Zabbix Server.

The Nextcloud Template uses an HTTP request to the API to get information as xml, tenaslate it to JSON and then use a lot of dependent items.

The initial request and transformation from xml to json works well but the json path for some items are not correct (anymore) ‐ Bug #1

The dependent item has nothing to do wirh xml (just the master item does) but when it fails, Zabbix Server shows "xml not supported" error - Bug #2

I reimplemented the version checks for apps and additionally for the whole Nextcloud instance:

Add parameters in

Nextcloud: Get server information

format=json          # (optional: delete the xml preprocessing)
skipUpdate=false # (for instance updates)
skipApps=false     # (for the original functionallity mentioned above)

Customize the JSON path for the dependent item (optional, if you add instance updates)

$.ocs.data.nextcloud.system.update.available

Pitastic Hello

Where exactly do you have to configure this?

Pitastic : Thanks for your analysis of this problem. This problem still seems to exist in 7.4.0 version of the template and I did not find an active bug report about it so I submitted one: ZBX-26739
