Types ¶
type Backend ¶
type Backend interface {
// ProcessHTTPRequest is used to perform HTTP audit process
ProcessHTTPRequest(req *http.Request) bool
// Match is used to determine if the backend matches
Match(*BackendLabels) bool
ProcessBeforeHandler() bool
}
Backend defines what function audit backend should hold
func NewLocalLogBackend ¶
NewLocalLogBackend returns a LocalLogBackend
func NewPrometheusHistogramBackend ¶
func NewPrometheusHistogramBackend(histogramVec *prometheus.HistogramVec, before bool) Backend
NewPrometheusHistogramBackend returns a PrometheusHistogramBackend
type BackendLabels ¶
type BackendLabels struct {
Labels []string
}
BackendLabels is used to store some audit backend labels.
type LabelMatcher ¶
type LabelMatcher struct {
// contains filtered or unexported fields
}
LabelMatcher is used to help backend implement audit.Backend
func (*LabelMatcher) Match ¶
func (m *LabelMatcher) Match(labels *BackendLabels) bool
Match is used to check whether backendLabel is in the labels
type LocalLogBackend ¶
type LocalLogBackend struct {
*LabelMatcher
*Sequence
}
LocalLogBackend is an implementation of audit.Backend and it uses `github.com/pingcap/log` to implement audit
func (*LocalLogBackend) ProcessHTTPRequest ¶
func (l *LocalLogBackend) ProcessHTTPRequest(r *http.Request) bool
ProcessHTTPRequest is used to implement audit.Backend
type PrometheusHistogramBackend ¶
type PrometheusHistogramBackend struct {
*LabelMatcher
*Sequence
// contains filtered or unexported fields
}
PrometheusHistogramBackend is an implementation of audit.Backend and it uses Prometheus histogram data type to implement audit. Note: histogram.WithLabelValues will degrade performance. Please don't use it in the hot path.
func (*PrometheusHistogramBackend) ProcessHTTPRequest ¶
func (b *PrometheusHistogramBackend) ProcessHTTPRequest(req *http.Request) bool
ProcessHTTPRequest is used to implement audit.Backend
type Sequence ¶
type Sequence struct {
// contains filtered or unexported fields
}
Sequence is used to help backend implement audit.Backend
func (*Sequence) ProcessBeforeHandler ¶
ProcessBeforeHandler is used to identify whether this backend should execute before handler
