You can't with Prometheus + blackbox_exporter. Prometheus stores only numeric (float64) values. Labels are strings, but to work properly it also requires a limited set of distinct label values (to avoid cardinality explosion). Therefore, blackbox_exporter doesn't put arbitrary dynamic text in labels.
You would need to look at a logging system, such as loki, which can store arbitrary text logs. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
