Tiers []CakeTier `json:"tiers"`
UpdatedAt time.Time `json:"updated_at"`
// Computed per-poll by HistoryStore.Record — not parsed from tc output.
// Zero on the first poll (no previous sample to diff against).
TxBytesPerS float64 `json:"tx_bytes_per_s"`
DropsPerS float64 `json:"drops_per_s"`
MaxAvDelayMs float64 `json:"max_av_delay_ms"`
MaxPkDelayMs float64 `json:"max_pk_delay_ms"`
}
CakeStats holds all parsed information for a single CAKE qdisc instance.
type CakeTier ¶
type CakeTier struct {
Name string `json:"name"`
Thresh string `json:"thresh"`
Target string `json:"target"`
Interval string `json:"interval"`
PkDelay string `json:"pk_delay"`
AvDelay string `json:"av_delay"`
SpDelay string `json:"sp_delay"`
Backlog string `json:"backlog"`
Pkts uint64 `json:"pkts"`
Bytes uint64 `json:"bytes"`
WayInds uint64 `json:"way_inds"`
WayMiss uint64 `json:"way_miss"`
WayCols uint64 `json:"way_cols"`
Drops uint64 `json:"drops"`
Marks uint64 `json:"marks"`
AckDrop uint64 `json:"ack_drop"`
SpFlows uint64 `json:"sp_flows"`
BkFlows uint64 `json:"bk_flows"`
UnFlows uint64 `json:"un_flows"`
MaxLen uint64 `json:"max_len"`
Quantum uint64 `json:"quantum"`
}
CakeTier holds per-tier statistics from the CAKE table section. All counters use uint64 to handle arbitrarily large values without overflow. (Fields are identical to the original parser package.)
type HistoryResponse ¶
type HistoryResponse map[string][]HistorySample
HistoryResponse is the serializable representation of the in-memory history store. It's a map from interface name to an ordered slice of samples.
type HistorySample ¶
type HistorySample struct {
T int64 `json:"t"` // unix timestamp (seconds)
Tx float64 `json:"tx"` // bytes transmitted per second (TX throughput)
Av float64 `json:"av"` // max av_delay across all tiers (milliseconds)
Pk float64 `json:"pk"` // max pk_delay across all tiers (milliseconds)
Dr float64 `json:"dr"` // packet drops per second
}
HistorySample is one time-series data point for a single CAKE interface. All numeric values are float64 so they can be directly consumed by charting libraries (uPlot, Chart.js, etc.).
type StatsResponse ¶
type StatsResponse struct {
Interfaces []CakeStats `json:"interfaces"`
UpdatedAt string `json:"updated_at"`
}
StatsResponse is the JSON message sent to clients containing the current interface statistics along with a timestamp.
func (StatsResponse) MarshalJSON ¶
func (r StatsResponse) MarshalJSON() ([]byte, error)
MarshalJSON implements json.Marshaler using a manually allocated buffer. It mirrors the allocation behaviour that easyjson would produce; we include it here so the repository can build without requiring codegen. In a real release, run `go generate ./...` to produce optimized functions.
