## Average Query Response Time

The Average Query Response Time graph shows information collected using the Response Time Distribution plugin sourced from [table `INFORMATION_SCHEMA.QUERY_RESPONSE_TIME`](https://www.percona.com/doc/percona-server/5.7/diagnostics/response_time_distribution.html#QUERY_RESPONSE_TIME). It computes this value across all queries by taking the sum of seconds divided by the count of queries.

## Query Response Time Distribution

Query response time counts (operations) are grouped into three buckets:

- 100 ms - 1 s

- 1 s - 10 s

- > 10 s
