 Q:

What is an Arc Fault Circuit Interrupter?

What is an Arc Fault Circuit Interrupter (AFCI) and where should they be used?

A:

AFCI's detect patterns of current that usually indicate some sort of electrical problem. Unlike a GFCI which is making sure that current going out = current coming back, AFCI's try to look for electrical usage that would not trip a GFCI but might be something causing an electrical fire. Most code now requires them for bedroom circuits.
The one major drawback for them is that some stuff tricks them into tripping. Often times larger machines with motors, like a vacuum cleaner or power tool can trip them. They are still a good thing to have, just be aware of this limitation

 Q:

Grafana - Show metric by field value

I'm currently trying to create a graph on Grafana to monitor the status of my servers, however, I can't seem to find a way to use the value of a field as the value to be displayed on the graph. (Datasource is ElasticSearch)
The following "document" is going to be sent to GrayLog (which saves to Elastic) every 1 minute for an array of regions.
{
  "region_key": "some_key",
  "region_name": "Some Name",
  "region_count": 1610
}

By using the following settings, I can get Grafana to display the count of messages it received for each region, however, I want to display the number on the region_count field instead.

Result:

How can I accomplish this? is this even possible using Elastic as the datasource?

A:

1) Make sure that your document includes a timestamp in ElasticSearch.
2) In the Query box, provide the Lucene query which narrows down the documents to only those related to this metric
3) In the Metric line, press "Count" and change that to one which takes a specific field: for example, "Average"
