Hi,
I am hoping to get some extra brains in this project. I am trying to monitor the Dell PowerVault ME4024 with a JSON file, using LLD with a dependent item. At the moment, Dell does not provide or has a working MIB to use SNMP to monitor this device with Zabbix.
I have created an Python script to generate a JSON file, with the selected API basetype properties. An extract of the Python script is shown below.
After successfully creating the JSON file, which contains several JSON arrays. Each JSON array contains several JSON Objects. An example JSON file is shown below.
At this moment, I am able to create items (JSON array: system) configured with an Master Item. But I failed to created a Discovery Rule for the JSON array: controllers. I have researched different options and methods, but all failed. Currently, I got one Discovery Rule configured:
Links consulted:
- https://blog.zabbix.com/low-level-di...t-items/13634/
- https://www.zabbix.com/forum/zabbix-...m-prototype
How can I make this happen? Only one working configuration is needed, to be an example for others.
