Velope

Simple Velocity plugin for server balancing & organising.

Features

Server groups with balancer and commands to have direct access to them
Kick handler
Lobby command (go to one of the current server's parent group)
List of veloped servers, smart config reload (WIP)
Initial sever group (instead of just one static server, players will be connected to the group's balancer determined server on join)
AdvancedPortals integration.

AdvancedPortals integration

If you have identically named destinations on all the group's servers you can specify its name for the portal (bungee:<group_name>), and it will work on any server (inside the group). Be sure to enable it:

  "integrations": {
"advancedPortalsSupportEnabled": true
},
...

Commands

/velope - Get info about plugin as well as get a list of accessible commands | (no permission)
/velope list - Get list of all veloped servers (groups) there are | velope.list
/velope reload - Reload config | velope.reload
/velope recent <player_name> - View the most recent redirect from Velope | velope.recent
/vstatus <server_name> - Get status of either regular or veloped server | velope.status.use
/lobby (/leave) - Connect to parent veloped Server (if there's any) | velope.use.lobby

Config (Description)

Example configuration:

{
  "integrations": {
    "advancedPortalsSupportEnabled": false
  },
  "failureSettings": {
    "maxFailures": 2,
    "failureCleanInterval": 45000
  },
  "groups": [
    {
      "name": "hubs",
      "servers": ["hub0", "hub1"],
      "balanceStrategy": "HIGHEST",
      "command": {
        "label": "hub"
      }
    },
    {
      "name": "bedwars_lobbies",
      "servers": ["bwlobby0"],
      "balanceStrategy": "LOWEST",
      "parent": "hubs",
      "omitFakeServer": true,
      "command": {
        "label": "bedwars",
        "aliases": [
          "bw"
        ]
      }
    }
  ],
  "rootGroup": "hubs",
  "initialGroup": "hubs",
  "fetchOnlineAlternativeEnabled": false,
  "pingerSettings": {
    "cacheTtl": 10000,
    "pingInterval": 10000,
    "logUnavailableCooldown": 120000
  }
}

Here you define server groups. Each server group will be represented with its own Velocity server (if omitFakeServer is not set to true), which I call " Veloped" server.

Name of Veloped server is equal to the name of the group. When the player connects to one of those servers, Velope redirects them to the server chosen by the balancer amongst those defined in a corresponding group. You can specify commands to access each individual group as well as its aliases and a permission to use that command.

Root group is a group that will be used when there are no servers in the parent group (right now, only KickHandler utilizes it).

Initial group is used when player initially connects to the proxy: instead of just one static server, player will be connected to the group's balancer determined server.

In pinger settings section you can change:

Cache TTL - how long server information should be cached until it will be refreshed
Ping Interval - specifies the time interval servers are pinged to retrieve their info
Log Unavailable Cooldown - specifies the cooldown for logging unsuccessful pings

In failure settings section you can change:

Max Failures - the amount of failures after which player is going to be disconnected (KickHandler)
Failure Clean Interval - interval of recorded failure's purge (milliseconds)

You can specify whether Velope should grab online from:

"fetchOnlineAlternativeEnabled": false from ping (might include fake players)
"fetchOnlineAlternativeEnabled": true from Velocity API

Balancer Strategies

For the moment there are two basic balancer strategies:

FIRST - created for testing purposes, it always outputs the first server that has been associated with a group
HIGHEST - basically tries to fill the server: outputs server with the largest amount of players connected
LOWEST - outputs server with the least amount of players connected
RANDOM - outputs random available server

Support

This plugin is somewhat just a bit better than "proof-of-concept" so there's a lot of things to hone.
