> Currently, the event "Blocked system-critical thread has been detected" is only reported via the log by WorkersRegistry. 
> There is no way to track how often such events occur without parsing (grepping) the log.
> We need to expose this as a metric so the count of events can be monitored through the metrics subsystem (e.g. JMX, system views, exporters) instead of relying on log parsing.
