Hello, how are you? I'm using Zabbix and Grafana to display the graphs... In Zabbix I have already created my host and within it a data download with the metrics prototypes... (tx, rx, serial), they are already working perfectly and I can graph them in Grafana... but I want to use dynamic global variables to be able to change according to the serial I choose to bring me the respective tx and rx of that serial... My keys are composed of tx.[{#SNMPINDEX}], rx.[{#SNMPINDEX}], serial.[{#SNMPINDEX}] I was thinking that I could use the SNMPINDEX as a reference to relate them but I don't know how... or maybe there is another way to do it. Thanks
