View Source Telemetry Events
Partisan uses the telemetry library for instrumentation.
A Telemetry event is made up of the following:
name- A list of atoms that uniquely identifies the event.measurements- A map of atom keys (e.g. duration) and numeric values.metadata- A map of key-value pairs that can be used for tagging metrics.
Membership Events
[partisan, membership, peer, join]
This event is triggered when a node joins the cluster.

}[partisan, membership, peer, leave]
This event is triggered when a node leaves the cluster.

}[partisan, membership, peer, up]
This event is triggered when a node successfully establishes all necessary channel connections with a peer. In other words, the node has established the number of connections for each channel based on the parallelism setting for the corresponding channel.

listen_addrs => [
#{ip => {127,0,0,1}, port => 10200}
]
}[partisan, membership, peer, down]
This event occurs when a peer disconnects, and there are no established channel connections with that peer.

}[partisan, membership, peer, channel, up]
Emitted every time a channel reaches the desired number of connections i.e. parallelism.

}Channel Events
[partisan, channel, configured]
Emitted once for every channel every time the channels configuration parameter is modified. It provides a measurement of the count of channels. The metadata includes the channel name and options i.e. partisan:channel_opts().

}
}Socket Events
[partisan, socket, open]
Emitted once for every socket that is open and waiting for connection with another socket. It provides a measurement of the count of connect open events.
