LLD issue - value is showing in key

[jan.motejzik]

Hello, I would like to ask about a problem that I have been struggling with for several days.

I would like to monitor the values from the json file, specifically the number of days remaining until the end of the expiration. I think I have a problem with the LLD settings, the value that should appear for a specific item as value is displayed in the key and there is Parameter is not allowed error.


1) python script returns me data in json:

[
    {
        "{#ROBOT}": "Alfa",
        "{#DAYS}": "63"
    },
    {
        "{#ROBOT}": "Gamma",
        "{#DAYS}": "14"
    },
    {
        "{#ROBOT}": "Delta",
        "{#DAYS}": "19"
    }
]

2)

discovery rule:
key: rpa.status

item prototype:
name: {#COMPANY}
key: rpa.status[{#DATE}]

3)

zabbix agent:
UserParameter=rpa.status,cat /opt/zabbix/test (just for test purposes)




what am I missing? thanks for the hints !

do I setup lld macros correctly?


thanks

You already have them in there. Just like built in block devices discovery returns json with formatted LLD macros. (https://www.zabbix.com/documentation...amples/devices).
No need to define any others... (and what you defined there does not exist in your json.., there is no key called "robot" )

thank you for your reply, however, despite creating several templates, I don't understand why this one still doesn't work for me ..



I was editing the UserParameter for zabbix agent:

UserParameter=rpa.status[*],....


but dont get, why I didnt get the right value ....


could you please help me with these settings ?


thanks

Wait... you want that this userparameter would pull correct number via that python script, which outputs that json in first post?

[jan.motejzik]

I have python script which returns me json file from first post. From json I need monitor a value from {#DAYS} section, which is number of days to expire.....


as u can see at the screenshots, like a last value there is nothing instead of number of expire days ...



at the screenshots u can see my whole settings ...


User Parameter is UserParameter=rpa.check[*],python3.9 /opt/script.py




thanks for helping ..
