Struct VCLPrometheusExporter 

pub struct VCLPrometheusExporter { /* private fields */ }

Prometheus metrics exporter for VCL Protocol.

Exposes all VCL metrics in Prometheus text format, ready to be scraped by a Prometheus server.

Implementations

impl VCLPrometheusExporter

pub fn new() -> Result<Self, VCLError>

Create a new exporter with its own Prometheus registry.

pub fn update_bytes_sent(&self, bytes: u64)

Record bytes sent.

pub fn update_bytes_received(&self, bytes: u64)

Record bytes received.

pub fn update_packets_sent(&self, count: u64)

Record packets sent.

pub fn update_packets_received(&self, count: u64)

Record packets received.

pub fn update_retransmit(&self)

Record a retransmission.

pub fn update_dropped(&self, count: u64)

Record dropped packets.

pub fn set_connections_active(&self, count: f64)

Set active connection count.

pub fn update_reconnect(&self)

Record a reconnect.

pub fn update_handshake(&self)

Record a handshake.

pub fn update_key_rotation(&self)

Record a key rotation.

pub fn set_loss_rate(&self, rate: f64)

Set current loss rate.

pub fn set_rtt_seconds(&self, rtt: f64)

Set current RTT in seconds.

pub fn set_cwnd(&self, cwnd: f64)

Set current congestion window.

pub fn set_obfuscation_overhead(&self, ratio: f64)

Set obfuscation overhead ratio.

pub fn set_mtu(&self, mtu: u16)

Set current MTU.

pub fn update_dns_queries(&self, count: u64)

Record DNS queries intercepted.

pub fn update_dns_blocked(&self, count: u64)

Record DNS queries blocked.

pub fn update_dns_cache_hits(&self, count: u64)

Record DNS cache hits.

pub fn update_fragments_sent(&self, count: u64)

Record fragments sent.

pub fn update_fragments_reassembled(&self, count: u64)

Record fragments reassembled.

pub fn set_tunnel_state(&self, state: f64)

Set tunnel state (0=Stopped, 1=Connecting, 2=Connected, 3=Reconnecting, 4=Failed).

pub fn update_from_metrics(&self, m: &VCLMetrics)

Update all counters from a VCLMetrics snapshot.

Counters are incremental — call this each time you want to push the delta since last call. For simplicity this resets and re-adds the full values (idempotent for Prometheus pull model).

pub fn update_from_tunnel_stats(&self, stats: &TunnelStats)

Update all gauges and counters from a TunnelStats snapshot.

pub fn render(&self) -> String

Render all metrics in Prometheus text exposition format.

Serve this on an HTTP endpoint (e.g. /metrics) for Prometheus to scrape.

pub fn registry(&self) -> &Registry

Returns the underlying Registry for advanced use.
