Summary

Service downtime, s	MTTR, s	Absolute performance degradation, s	Relative performance degradation, ratio
477.8 ±5.9	570.3 ±2.8	18 ±17	3.1 ±2.0

Metrics:

• Service downtime is the time interval between the first and the last errors.
• MTTR is the mean time to recover service performance after the fault.
• Absolute performance degradation is an absolute difference between the mean of operation duration during recovery period and the baseline's.
• Relative performance degradation is the ratio between the mean of operation duration during recovery period and the baseline's.

Details

This section contains individual data for particular scenario runs.

Run #1

Baseline

Baseline samples are collected before the start of fault injection. They are used to estimate service performance degradation after the fault.

Samples	Median, s	Mean, s	Std dev	95% percentile, s
36	8.6	8.8	1.2	11

Service downtime

The tested service is not available during the following time period(s).

#	Downtime, s
1	478 ±35

Service performance degradation

The tested service has measurable performance degradation during the following time period(s).

#	Time to recover, s	Absolute degradation, s	Relative degradation
1	570.3 ±7.6	18 ±17	3.1 ±2.0
