Web Scenarios with JSON output

[titansmc]

Hi,
Is it possible to set a web scenario that matching pattern is:

{"Test-Search":{"healthy":true},"DB":{"healthy":true},"DI S":{"healthy":true},"DMS":{"healthy":true}}

Something else should fail.
It keeps saying

13:58:03

Step "Healthcheck" [1 of 1] failed: required pattern "{"Test-Search":{"healthy":true},"DB":{"healthy":true},"DI S":{"healthy":true},"DMS":{"healthy":true}}" was not found on https://test.example.com/converis/metrics/healthcheck
