Gatling is a popular open-source load testing tool that allows teams to simulate large numbers of users making requests to a system, helping to identify performance issues and bottlenecks.

Latency Lingo integrates with Gatling by reading the results log file. Once integrated, test results will be published to Latency Lingo to help you with performance test analysis and automation.


Install the Latency Lingo CLI and sign up for an account.

Locate your Gatling results log file. This is the simulation.log that is automatically generated and stored in the Gatling results folder.

Here is a sample of the expected format:

RUN computerdatabase.BasicSimulation    basicsimulation 1647457743559   Test sample 2   3.7.6
USER Sample Test START 1647457744600
USER Sample Test START 1647457744599
REQUEST GET test 1647457744634 1647457744825 OK
REQUEST GET test 1647457744634 1647457744821 OK


Run your Gatling load test as you normally would.

Once the test is completed, run the publish command to upload the results to Latency Lingo with the gatling format:

latency-lingo-cli publish \
--file <simulation.log results file> \
--label <test name> \
--api-key <latency lingo api key> \
--format gatling

The test will be available in your Latency Lingo dashboard and a link is included in the CLI output:
