What did you do that produced an error?

I ran the exporter with the mentioned flags

What did you expect to see?

I expected to see metrics like mysql_perf_schema_events_statements_seconds_total

What did you see instead?

This specific metric: mysql_perf_schema_events_statements_seconds_total, wasn't scraped.
P.S. It works fine in 0.15.0
