Deployment logs and limitations

Harness deployment logging has the following limitations:

Log size limits​

The following table shows the log size limits for different Harness modules:

Limit TypeCI ModuleOther Modules (CD, CCM, etc.)
Total log size per step5MB25MB
Maximum size per log line70KB25KB

Log truncation behavior​

  • When logs exceed the size limit, Harness truncates the oldest log lines and retains the newest ones.
  • You can export full CI logs to an external cache. For information about CI log limits and exporting CI logs, go to Truncated execution logs.

Viewing limits​

  • Line limit: The Harness log service has a limit of 5000 lines. Logs rendered in the Harness UI are truncated from the top if the logs exceed the 5000 line limit.
note

If you need logs more than 5000 lines, contact Harness Support

  • Step runtime limit: Steps exceeding a 5-hour runtime may experience log visibility issues. We are working to address this limitation.
