When you select a transaction from the key transaction index, the key transaction's Overview page appears. The Overview page contains charts for response time, Apdex, throughput, and other data. It is similar to the main Overview page in APM, with standard New Relic page functions.
The SLA report page for a key transaction displays Service Level Agreement reports for that transaction. The SLA reports include daily and weekly data about throughput, response time, and Apdex. You can also download the report as a comma-separated value (CSV) spreadsheet.
