Ala Logger

Ala Logger

Something breaks, and the person helping you asks for the log. Find the file, open it, copy the right part, paste it somewhere that does not mangle it. Or type one command.

/alalogger
[Ala Logger] Looking for the log file...
[Ala Logger] Uploading latest.log (21 KB)...
[Ala Logger] Log uploaded: alacraft.day/en/logs/aB3xY9kM [what's wrong] [delete]
[Ala Logger] Removed before sending: 2 IP addresses, 3 account names in paths.
[Ala Logger] Found 2 known problem(s):
  1. Java 17 is installed, but this version needs Java 25
  2. Port 25565 is already in use by another process

You get a link. Anyone can open it in a browser and read the whole file, properly formatted and scrollable. No account, no download, no wall of text pasted into chat.

Runs on Fabric, NeoForge and Forge, on Minecraft 26.3 and 26.2, on a server, in singleplayer and on the client.

Commands

• /alalogger uploads the current log. /alog is shorter and does the same.
• /alalogger crash uploads the newest crash report, including the JVM ones (hs_err_pid*.log) that most tools will not touch.
• /alalogger list shows every log and report with its size and age, each clickable.
• /alalogger delete <id> removes one you uploaded. Still works after a restart.
• /alalogger insights <id> shows the detected problems again.
• /alalogger history lists the links this server handed out, newest first, so the one you pasted into a ticket yesterday is still findable today.

After a crash

When the game crashed last time, the next launch says so: a small "!" button beside Multiplayer on the title screen opens the files the crash left. That is the crash report, the JVM's own error log, or, if the game was closed by force and wrote nothing, the log of that session. One click uploads one, cleaned the same way, with buttons to copy the link, open it in the browser, or copy a ready message for a support chat. Nothing is sent until you click, and each crash is offered once.

It reads the log for you

The site looks the file over and says what it found, right there in chat. Wrong Java version, a port already in use, a mod missing the one it depends on. Often that is the whole answer and nobody needs to open the link at all.

In the player's own language

Messages, detected problems and links follow each player's client language: English, Russian, Ukrainian, German, French, Spanish, Japanese, Portuguese, Chinese, Polish, Turkish and Korean. Players on a vanilla client get their language too, because the text is chosen on the server side.

Before anything leaves the machine

The mod removes IP addresses, e-mail addresses, your account name from file paths, session tokens, API keys, passwords and the world seed, then tells you what it took out. Nothing is uploaded unless someone runs the command or clicks Upload.

Uploaded logs stay for 90 days after they were last opened, and you can delete one at any time.

Requirements

Minecraft 26.3 or 26.2, and Java 25 or newer. Each release has a file for each game version and loader; pick the one that matches yours.

NeoForge for 26.3 is itself still in beta, so that one file is published as a beta. Nothing else is needed on NeoForge or Forge.
