Service Level Agreements

An SLA is a set of thresholds that applies to a single statistic (average response time, hit rate, and so on). An SLA belongs to a family of service levels:

• Per Run: These runtime-based SLAs are evaluated at the end of the test on:
  • the global test statistics; and
  • the global statistics for each element linked to a profile.
• Per Time Interval: These interval-based SLAs are evaluated each time a result is received during test runtime. When a threshold in this family of SLAs is breached, an alert is triggered in real time.
  For more information about real-time alerts, see Runtime alerts.
