Functions ¶
func RegisterCollector ¶
Types ¶
type DumpCallback ¶
type DumpCallback func(*MetricsKey, *MetricsValue)
DumpCallback represents the signature of the callback function expected by the DumpWithCallback method, which in turn is used to iterate all the keys/values of a ratelimit metrics map.
type Key ¶
type Key struct {
Usage usageType `align:"usage"`
Key uint32 `align:"key"`
}
Key must be in sync with struct ratelimit_key in <bpf/lib/ratelimit.h>
type MetricsKey ¶
type MetricsKey struct {
Usage usageType `align:"usage"`
}
MetricsKey must be in sync with struct ratelimit_metrics_key in <bpf/lib/ratelimit.h>
func (*MetricsKey) New ¶
func (k *MetricsKey) New() bpf.MapKey
func (*MetricsKey) String ¶
func (k *MetricsKey) String() string
type MetricsValue ¶
type MetricsValue struct {
Dropped uint64 `align:"dropped"`
}
MetricsValue must be in sync with struct ratelimit_metrics_value in <bpf/lib/ratelimit.h>
func (*MetricsValue) New ¶
func (v *MetricsValue) New() bpf.MapValue
func (*MetricsValue) String ¶
func (v *MetricsValue) String() string
type RatelimitMetricsMap ¶
type RatelimitMetricsMap interface {
DumpWithCallback(DumpCallback) error
}
RatelimitMetricsMap interface represents a ratelimit metrics map, and can be reused to implement mock maps for unit tests.
