- Saved Screenshots / Saved DOMs not showing
Screenshots and Saved DOMs require a persistent storage volume to be stored on as these are not saved in the database. Additionally in a multiple controller setup, this same persistent volume should be made available to all controller instances. If this is not the case then when requested a controller may not be able to retrieve some or all of the screenshots or saved DOMs requested.
Issues can also occur with agents configured to store screenshots and saved DOMs on the same persistent volume and location as any controller, and the agent hasSend Check Filesenabled in its configuration, with the agent deleting the file after being successfully sent to the controller. If an agent has the same persistent volume and location configured as a controller, thenSend Check Filesshould be disabled in the agent configuration, which also saves on network bandwidth as these files do not need to be sent to the controller for storage anyway. If using agents that are auto-registering with the controllers, then the environment variableAGENT_SEND_FILEScan be set to a value offalse.
