Service Level Objectives

Set performance targets. Measure compliance on every run.

Service Level Objectives are now available in Gatling Enterprise Edition. Define performance thresholds directly on any test (no code change required) and get a precise compliance score after every run.                                                                                                                                                                                            
                                                                                                                                                                                                       

What you can define

Each SLO is built from three parameters:                                                                                                                                                              
                 

- Metric — response time percentile (p50, p95, p99, up to p99.9999) or error ratio across all scenarios
- Threshold — in milliseconds for response time, as a percentage for error ratio
- Operator — less than (<) or less than or equal (≤)


You can stack multiple SLOs on a single test. Each one is evaluated and reported independently.


Compliance you can read at a glance                  


 
SLO results appear in the run summary as color-coded gauges — one per SLO. Compliance is the percentage of seconds during the run where your condition was met. Ramp-up and ramp-down periods are    
 automatically excluded.
                                                                                                                                                                                                       
 - Green: met 99% of the time or more                                                                                                                                                                  
 - Orange: met between 90% and 99% of the time
 - Red: met less than 90% of the time                                                                                                                                                                  
                 

Owned at the right level

 
SLOs are configured directly in Gatling Enterprise Edition. Engineering managers and platform teams define and adjust thresholds independently, without touching simulation code, without opening a  
PR.
