Accessing Driverless AI Logs

Driverless AI provides a number of logs that can be retrieved while visualizing datasets, while an experiment is running, and after an experiment is completed.

While Visualizing Datasets

When running Autovisualization, you can access the Autoviz logs by clicking the Display Logs button on the Visualize Datasets page.

Autoviz logging

This page presents logs created while the dataset visualization was being performed. You can download the vis-data-server.log file by clicking the Download Logs button on this page. This file can be used to troubleshoot any issues encountered during dataset visualization.

While an Experiment is Running

While the experiment is running, you can access the logs by clicking on the Log button on the experiment screen. The Log button can be found right below the CPU usage meter.

Log button

Clicking on the Log button will present the experiment logs in real time. You can download these logs by clicking on the Download Logs button in the upper right corner.

Log when experiment is running

Only the h2oai_experiment.log will be downloaded while the experiment is running (for example: h2oai_experiment_tobosoru.log). It will have the same information as the logs being presented in real time on the screen.

For troubleshooting purposes, it is best to view the complete h2oai_experiment.log (or h2oai_experiment_anonymized.log). This will be available after the experiment finishes, as described in the next section.

After an Experiment has Finished

If the experiment has finished, you can download the logs by clicking on the Download Logs button at the center of the experiment screen.

Download Logs button

This will download a zip file which includes the following logs:

  • h2oai_experiment.log: This is the log corresponding to the experiment.
  • h2oai_experiment_anonymized.log: This is the log corresponding to the experiment where all data in the log is anonymized.
  • h2oai_server.log: Contains the logs for all experiments and all users.
  • h2oai_server_anonymized.log: Contains the logs for all experiments and all users where all data in the log is anonymized.
  • h2o.log: This is the log corresponding to H2O-3. (H2O-3 is used internally for parts of Driverless AI.)

For troubleshooting, it is best to view the h2oai_experiment.log or h2oai_experiment_anonymized.log.

The following additional information about your particular experiment will also be included in the zip file:

  • tuning_leaderboard.txt: The results of the parameter tuning stage. This contains the model parameters investigated and their performance.
  • gene_summary.txt: A summary of the feature transformations available for each gene over the feature engineering iterations
  • features.txt: The features used in the final Driverless AI model along with feature importance and feature description
  • details folder: Contains standard streams for each of the subprocesses performed by Driverless A. This information is for debugging purposes.
