Overview ¶
Package relabel provides label manipulation for Pyroscope profiles.
Label Handling: The component handles two types of label representations: - labels.Labels ([]Label): Used by Pyroscope and relabeling logic - model.LabelSet (map[string]string): Used for efficient fingerprinting and cache lookups
Cache Implementation: The cache uses model.LabelSet's fingerprinting to store label sets efficiently. Each cache entry contains both the original and relabeled labels to handle collisions and avoid recomputing relabeling rules.

Types ¶
type Arguments ¶
type Arguments struct {
// Where the relabeled metrics should be forwarded to.
ForwardTo []pyroscope.Appendable `alloy:"forward_to,attr"`
// The relabelling rules to apply to each log entry before it's forwarded.
RelabelConfigs []*alloy_relabel.Config `alloy:"rule,block,optional"`
// The maximum number of items to hold in the component's LRU cache.
MaxCacheSize int `alloy:"max_cache_size,attr,optional"`
}
func (*Arguments) SetToDefault ¶
func (a *Arguments) SetToDefault()
SetToDefault implements syntax.Defaulter.
type Component ¶
type Component struct {
