How to format a DQL to accept a "*" wildcard?

tdavison76 — Thu, 23 Apr 2026 13:04:13 GMT

Hello, I'm creating a Dashboard that shows Service and Endpoint metrics. It first loads up every endpoint for a Service, but I have an $Endpoint variable that has a Default value of "*". In my tile, it fails when an Endpoint isn't selected and it's using the Default value. Could someone help me out on how I should structure the DQL to not fail on a wildcard, or if it's another route I should be taking.

Here's the DQL I am trying to use:

timeseries { sum(dt.service.request.count), value.A = sum(dt.service.request.count, scalar: true) }, filter: { matchesValue(endpoint.name, $Endpoint) }

Thanks,

Tom

Try this

timeseries { sum(dt.service.request.count), value.A = sum(dt.service.request.count, scalar: true) }, filter: { in(endpoint.name, $Endpoint) }

Hello, thank you very much for the quick response. I tried out the DQL but unfortunately, it doesn't return anything when the wildcard is used in the Variable.

Thanks again,

Tom

Dashboard tile

timeseries { sum(dt.service.request.count) }, by: { endpoint.name, dt.service.name } | filter matchesValue(dt.service.name, $Service) | filter matchesValue(endpoint.name, $Endpoint) | limit 5

Service Variable

smartscapeNodes SERVICE | filter isNotNull(name) | fields name | limit 10

Endpoint Variable

fetch spans | filter matchesValue(dt.service.name, $Service) | filter isNotNull(endpoint.name) | fields endpoint.name | limit 5

Hello, thank you for the details, still getting the same error with the Dashboard Tile example you provided:

A string containing only the wildcard'*' isn't allowed.

Thanks again,

Tom

wildcards are only allowed at he beginning or end not in the middle thats probably why
