File access traces with Tetragon
Tracing policies can be added to Tetragon through YAML configuration files that extend Tetragon’s base execution tracing capabilities. These policies perform filtering in kernel to ensure only interesting events are published to userspace from the BPF programs running in kernel. This ensures overhead remains low even on busy systems.
