I need to create an alert mail if there are no data points. We have the bunch of servers(250). We built grafana dashboard for those servers to check server health. In that for each server, we are reading CPU, RAM, and DISK space from each server. I need grafana alerts to trigger when there is no data streaming in any of the servers so that I can infer that the container is down. Currently, the graph just stops plotting and no alerts are triggered.
If the condition has “HAS NO VALUE” and there are no datapoint by any one of the servers. I need an alert mail, from that server we don’t get any data point.
Please help this. Thanks in advance.
