Makes the health check sync, it occassionally times out due to metric flushes taking longer than the threshold, this is generally not a problem and small short backlogs in the aggregator are expected (due to the flushes), the health checks shouldn't be failing because of it.
The health check itself is very useful though, we should not be ready if the aggregator would reject metrics.
