Hey everyone, thx for pinging.
Hello @sanashahbaz, and welcome to the foruns.
Well in your place I wouldn’t work directly from zabbix using one json text data and making grafana work. Because the data that’s grafana Plug-in pools from zabbix is already one json with other information, like the host, item name, etcetera.
My best advice for you is transforming each json record in a set of items in zabbix side (using preprocessing with dependent data) and them querying them and transforming them into the table. Some information on querying multiple items and querying them here: Multiple Metrics one table - #7 by isaqueprofeta
