Add a static metric to add labels

[Nicolai von Neudeck]

Hi everyone!

To configure useful alerts I need a reliable source for some labels that don’t change.
So that I can make alerts that show me metrics who *don’t* return timeseries with a certain labelset *anymore*.

Is there a nice way to add a constant metric via config to prometheus to get these labels? It should not be actually scraped but just given to prometheus via config.

E.g. the query:

places

should return:

places{city="Berlin",country="Germany",continent="Europe"} 1
places{city="Capetown",country="South Africa",continent="Africa"} 1

places{city="Cluj-Napoca",country="Romania",continent="Europe"} 1

places{city="Cairo",country="Egypt",continent="Africa"} 1

places{city="Jerusalem",country="Israel",continent="Asia"} 1

places{city="Woodlands",country="Singapore",continent="Asia"} 1

places{city="Quebec",country="Canada",continent="North America"} 1

places{city="La Paz",country="Bolivia",continent="South America"} 1

places{city="Mexico City",country="Mexico",continent="North America"} 1

places{city="Brisbane",country="Australia",continent="Australasia"} 1

places{city="Suva",country="Fiji",continent="Australasia"} 1

places{city="Montevideo",country="Uruguay",continent="South America"} 1

Have a nice weekend!

Those can be configured as recording rules.

- record: places

  expr: 1

  labels:

    city: Berlin

    country: Germany

    continent: Europe

Thank you very much Ben,

I have no idea how I could have overlooked that.
I’m sorry to have caused you unnecessary labour.
Have a wonderful weekend!
