To help monitor our server room temperature a bit better I want to put one individual temperature sensor from one of our servers as a widget on one of the dashboards so I don’t have to dig down into the individual server and then find the right sensor etc, however there doesn’t seem to be any way to do this ?
One approach is to add a Graph Widget with graph type sent to device_temperature, unfortunately there is no way to choose which sensor to display, so it just displays all of them… in a small box that can’t fit them all even if I wanted to.
On a server with 21 temperature sensors it just ends up looking like this with the graph not even visible due to so many legends:
The sensor I’m interested in is “Front Temp”, although I’d like to rename it as well…
Ok, so how about the image widget ? That would do if I could find a fixed URL that shows the most recent 6 hour temperature graph for that one sensor, unfortunately the clickable URL’s for the graphs are all dynamically generated and include timestamps so any image URL I might use will soon be out of date.
Is there some way to do what I’m trying to do using the existing widgets or is it just not possible ?
Ideally I’m trying to get the widget to look something like this:
Although it would be nice to rename the sensor to “Server Room” as well.
