Malcolm uses the Reporting plugin for OpenSearch Dashboards. Reports can be generated on-demand or defined using visualizations and dashboards, the discover view, or Notebooks pages. See Reporting in the OpenSearch documentation for usage instructions.
The Malcolm development team is aware of an issue exporting some dashboards as PDF and PNG reports using the Mozilla Firefox web browser. While the root cause and fix are being investigated, users that encounter this bug may attempt the action using another web browser.
