Types

type ActionContext added in v1.4.0

type ActionContext struct {
	Kevt   *kevent.Kevent
	Filter *config.FilterConfig
	Group  config.FilterGroup
}

ActionContext is the convenient structure for grouping the event that resulted in matched filter along with filter group information.

type Filter

type Filter interface {
	// Compile compiles the filter by parsing the filtering expression.
	Compile() error
	// Run runs a filter on the inbound kernel event and decides whether the event should be dropped or propagated to the downstream channel.
	Run(kevt *kevent.Kevent) bool
}

Filter is the main interface for the filter engine implementors.

type Rules added in v1.4.0

type Rules struct {
	// contains filtered or unexported fields
