Custom Labels
Synthetic monitoring allows you to define custom labels in your check definitions.
Query Custom Labels
Custom labels are published as an info metric sm_check_info.
All custom labels are prefixed with label_ to make sure they don’t conflict with system defined labels.
e.g: sm_check_info{label_env="prod"} query will show you check details with env custom label.
Query Check Metrics with Custom Labels
We can use group_left to get custom labels with check metrics data.
For example, probe_duration_seconds * on(job, instance, probe) group_left(label_env) sm_check_info
query will include label_env label in results.
You can then extend your query further, for example by filtering metrics using these labels
probe_duration_seconds * on(job, instance, probe) group_left(label_env) sm_check_info{label_env="prod"}
