Hi,
What I'm trying to do is get alerts if number of reporting hosts drops below expected values, i.e. if I monitor Elastic cluster and I expect it to have 4 nodes (all of them report metrics using telegraf), I would like to be notified if number of them drops below 4, which would mean that one (or more) of the nodes died. This is something I was able to do using collectd+graphite+grafana stack, but I'm looking into ways of transitioning to Telegraf + InfluxDB + Kapacitor.
Additionally, I would like to be able to track these changes in time, so also a way of using it in dashboard would be appreciated.
Thanks!
Peter
