How to configure a dashboard to show an expected value?

[centrisinfo]

Most of the time this applies to using "Counts" in a certain Dashboard. Is it possible to show an Expected value?

For example, I have a dashboard that counts a certain log each day. There should be 30 each day, but sometimes there are only 29 due to errors. Is it possible to visualize that info against the expected number of 30? Or even just visualize it on the dashboard report as 29/30?

Exactly what I was looking for. Thank you!

Use the eval command to create an "expected value" field.

| stats count
| eval expected=30

or

| stats count
| eval count=count . "/30"
