-TDengine users can modify and improve these alert rules according to their own business needs. In Grafana 7.5 and below versions, the Dashboard and Alert rules functions are combined, while in subsequent new versions, the two functions are separated. To be compatible with Grafana7.5 and below versions, an Alert Used Only panel has been added to the TDinsight panel, which is only required for Grafana7.5 and below versions.
