Randompatches (in)compatibility:
Set this in the randompatches.toml config file so random patches does not crash when started alongside connectivity:
mixin_blacklist = ["ServerPlayNetHandlerKeepAlive"]
Connectivity has some overlap with randompatches and happens to apply first, which makes random patches crash.
Timeoutout/XL packets mod is incompatible/not needed alongside this
If you enjoy this mod consider supporting the development, any support is greatly appreciated.
The development is an unpaid free-time activity, so any support helps being able to spend more time on it.

Network stats and Commands:
Commands for network stats show the traffic rate aswell as which packet is causing it. kb is short for kilobyte
Statistics are refreshed once per minute and save a history of up to 5 minutes. All commands have an optional minute count you can give it to display(1-5, 5 is default when no argument is given)
Normally most traffic is caused by chunk packets, modded packets should rarely exceed those.
Client side command to show outgoing traffic: /connectivity packetsClient
Server commands:
List traffic rate of all players: /connectivity packetsAllPlayers
List packets by type send to a specific player(example is player Dev): /connectivity packetsPlayer Dev
List all packets sent out by the server by packet type. /connectivity packetsSummary
Print the largest packet of a type to the latest.log, e.g. the packet called MovePacket: /connectivity printpacket MovePacket
