Grafana Alert to Cover multiple hosts

Hello All,

We have an ELK stack but want to configure alerting with Grafana. We want to set basic alert, if no logs have been received for 5 minutes an alert will fire. We have 6 different hosts sending logs to the ELK stack

Question is, do we have to create separate panels for each host or can we create one panel to cover all 6 hosts and individual alerts for each host within that one panel?

Any assistance would be appreciated.
