Minecraft Input Plugin broken for 1.13 based servers

[jhg03a]

Relevant telegraf.conf:

Any stock Minecraft input plugin config pointing to a valid Minecraft 1.13 based server.

System info:

Found with telegraf 1.9, but should affect all prior versions as well.

Steps to reproduce:

1. Create a Minecraft 1.13 server
2. Connect telegraf via the Minecraft input plugin to it

Expected behavior:

Some data as configured in the Minecraft scoreboard settings

Actual behavior:

No data

Additional info:

The input plugin is broken as a result of a change/bug in the RCON api. The plugin could be updated to instead of relying on a single RCON call for all the data to instead make +1 RCON calls to fetch player stats individually which does still work.

The plugin does still work for servers prior to the 1.13 update I believe.

Might be some time before Mojang gets to this, so the workaround might be the way to go. Do you know the command to list all players?

[jhg03a]

/scoreboard players list * would be replaced with a combination of /scoreboard players list and /scoreboard players list <playername> I believe.

Anything I can do to help?

I worked on this a bit last night but I still have a few hours of work. Turns out the response text changed as well so it has been a bit more work than expected, but I should have something ready for testing soon.

Moving to 1.11, the changes are a bit too large for a patch release. Should have a build for testing this evening.

This is great, thank you for keeping us in the loop.
