View simulation logs and history

After you run a simulation, view its logs to see how the behaviors are affecting your service, and review its run history to see past runs.

View simulation logs

After you run a simulation, you can view the logs for the mocks included in the simulation.

1. Open a workspace and select Tools > Simulator in the footer.
2. Select a simulation with running mocks.
3. View the logs in the Logs pane.

You can filter logs by path, mock, method, status code, and time range. This helps you analyze how the behaviors are affecting your service. For example, you can filter by status code to see only failed requests or filter by method to see how different endpoints are affected.

You can click a request to view more details about the request and response, such as the headers and body.

Click Clear logs to clear the logs for the mock.

To browse a deployed simulation’s request and response history from the command line, use the postman simulation log command.

View simulation history

Each time you run a simulation, Postman records the run. Use simulation history to review past runs, including who started each one, how long it ran, and the logs and state captured during the run.

1. Open a workspace and select Tools > Simulator in the footer.
2. Select the simulation.
3. Click History.

The history table lists each run with the following details:

Use the Started by and Source filters to narrow the list.
