Package metricsmap represents the BPF metrics map in the BPF programs. It is
implemented as a hash table containing an entry of different drop and forward
counts for different drop/forward reasons and directions.
const (
// MapName for metrics map. MapName = "cilium_metrics"
// MaxEntries is the maximum number of keys that can be present in the// Metrics Map.
MaxEntries = 65536
)
SyncMetricsMap is called periodically to sync off the metrics map by
aggregating it into drops (by drop reason and direction) and
forwards (by direction) with the prometheus server.
