Max Inden	d4f8ec2d48	misc/metrics: Track # connected nodes supporting specific protocol (#2734) ... * misc/metrics: Explicitly delegate event recording to each recorder This allows delegating a single event to multiple `Recorder`s. That enables e.g. the `identify::Metrics` `Recorder` to act both on `IdentifyEvent` and `SwarmEvent`. The latter enables it to garbage collect per peer data on disconnects. * protocols/dcutr: Expose PROTOCOL_NAME * protocols/identify: Expose PROTOCOL_NAME and PUSH_PROTOCOL_NAME * protocols/ping: Expose PROTOCOL_NAME * protocols/relay: Expose HOP_PROTOCOL_NAME and STOP_PROTOCOL_NAME * misc/metrics: Track # connected nodes supporting specific protocol An example metric exposed with this patch: ``` libp2p_identify_protocols{protocol="/ipfs/ping/1.0.0"} 10 ``` This implies that 10 of the currently connected nodes support the ping protocol.	2022-07-15 09:16:03 +02:00
