Functions ¶
func UpdateConfMap ¶ added in v0.9.0
func UpdateConfMap(mapDir string, v *TetragonConfValue) error
UpdateConfMap updates the configuration map with the provided value
func UpdateTgRuntimeConf ¶
UpdateTgRuntimeConf() Gathers information about Tetragon runtime environment and update the TetragonConfMap that is the BPF `tg_conf_map`.
It detects the CgroupFS magic, Cgroup runtime mode, discovers cgroup css's that registered during boot and propagated to all tasks inside their css_set, detects the deployment mode from kubernetes, containers, to standalone or systemd services. All discovered information will also be logged for debugging purpose.
On failures it returns an error, and it default prints a warning that advanced Cgroups tracking will be disabled which will affect process association with kubernetes pods and containers.
Important: this function does not take extra arguments as it should auto detect environment without any help. For testing use the specific variant that can be tuned with specific argument values.
