Sysdig capture files contain system calls and other OS events that can
be analyzed with either the open-source
(curses-based) utilities, and are displayed in the Captures module.
The Captures module contains a table listing the capture file name, the host it was retrieved from, the time frame, and the size of the capture. When the capture file status is uploaded, the file has been successfully transmitted from the Sysdig agent to the storage bucket, and is available for download and analysis.
This section describes how to create capture files in Sysdig Secure.
If upgrading from Essentials to Enterprise, users must go to
Settings>Teams><Your Team> and check the
Enable Captures box. They
must then log out and log in again. See also: User and Team
From June, 2021, the Captures module has moved under the Investigate menu in the nav bar.
