Node down alert - Grafana

Hi,

Is it possible to monitor node status with grafana? Say for example if the node down grafana should trigger alert.

I am looking for ICMP Ping when the nodes not pinging grafana should trigger alert.

We are using combination telegraf+influxdb+grafana stack.

I use Telegraf ping plugin to ping the ip addresses of a few hosts and write the response to InfluxDB “ping” measurement. I currently use the “default” ping method rather than the “native” ping method of the Telegraf ping plugin (see ping plugin documentation) since there was a recent issue with the Native Go Ping method, but this may now have been fixed)

I then simply use a grafana graph to graph the ping table results and (email/slack) alert when the average ping result is above 0 over a 5 minute period - The Telegraf ping result is 0 if online and 1 if not, so the alert only triggers if the node is offline for >5 mins but this is configurable. I also then get an alert when the host comes back online.

Hi,

Thanks for the update.

I tried it works well however grafana sends mail after 5 to 8 mins when the node offline.

This becomes problem especially for production environment if the node goes down should get an mail within 1 or 2mins.
