We using cloudwatch as datasource in grafana and are planing to use grafana alerting.
Lets take the below example here:
Assume we have AWS cloudwatch account added as datasource. The query on which I am setting up the alert is essentially number of requests coming to a load balancer. Thus the metrics in this case is the number of requests.
Now if we set a alert like this: if the avg number of request is more than 100 for last 5 mins, trigger and alert
Could you please help to understand how grafana will work in the back ground?
In this case, as the datastore for metrics is in cloudwatch, could you please help to understand how grafana will work in the background?
Will the alerting engine of grafana poll cloudwatch every 5 minutes and get all the values, then compute the avg and if it is greater than 100, it will generate the alert?
