Description :

Hi, I am trying to create a LLD based on the key vfs.file.get[/opt/dir/myfile] which returns a JSON according to the documentation.

But Zabbix says: cannot find the data array in the received JSON object when i try to use it.

As mentioned here https://support.zabbix.com/browse/ZBX-17685 :

"LLD expects an array of objects as input. It can be on its own like"

[{...},{...},...] 

1. deed, the key
2. vfs.file.get returns a JSON, but not in an array :

# zabbix_agent2 -t vfs.file.get[/opt/dir/myfile]
[s|{"basename":"myfile","pathname":"/opt/dir/myfile","dirname":", [...] }] 

Whereas the key vfs.dir.get which returns an array in the correct format. Notice the difference : the return json have a usable array for LLDs "[{*} \{json} {*}]" :

# zabbix_agent2 -t vfs.dir.get[/opt/dir/]
[s|[{"basename":"myfile","pathname":"/opt/dir/myfile","dirname":",[...] }]] 

Does this behavior is expected or it a bug?

Thx,

My environment : Zabbix_agent2 : 6.2.6 , OS CentOS Stream 8
