Service Level Indicators
Percentage
Service Level Indicators (SLIs) are specific, quantifiable measures of service reliability, such as uptime, error rates, or response times. These indicators are used to define the expected performance and reliability of a service.
Formula
(Measured Value / Expected Value) * 100
Example
If the expected uptime is 99.9% and the measured uptime is 99.5%, the SLI for uptime is (99.5 / 99.9) * 100 = 99.6%.
