+
+::: warning Compatibility with Plugins like CoreProtect
+
+As of v0.7.0, LunaticChat's channel chat feature is not compatible with logging plugins like CoreProtect.
+
+:::
+
+## Checking Channel Chat Logs
+
+Channel chat logs are stored in the `plugins/LunaticChat/logs/channelchat/` directory.
+
+Channel chat log files are saved in the following format:
+
+```
+{"timestamp":"2026-01-31T08:54:18.504343071Z","playerId":"ceaea267-39dd-3bac-931c-761ada671ebe","playerName":"m1sk9","channelId":"test","message":"Hello"}
+```
+
+## About File Size
+
+Each line is a complete JSON object, separated by line breaks, and the file as a whole is not a JSON array.
+
+```text

+Total: approximately 83 MB
+
+With a 30-day retention setting, the January 17 file will be automatically deleted tomorrow.
+
+### Size per Message
+
+Channel chat log entries are approximately 200 bytes per line.
+
+Assuming 1000 messages per hour:
+
+```text
+1000 msg/h × 24h × 220 bytes = 5,280,000 bytes ≈ 5.3 MB/day
+```
+
+With the default 30-day retention setting, this amounts to approximately **159 MB**.
+
+```text
+5.3 MB × 30 days = 159 MB
+```

+
+Due to the JSON format, using Promtail to ingest channel chat logs into Grafana Loki will parse them for easier reading.

+### 1メッセージあたりのサイズ
+
+チャンネルチャットのログエントリは1行につき，約200バイトです．
+
+1時間に1000メッセージの計算として
+
+```text
+1000 msg/h × 24h × 220 bytes = 5,280,000 bytes ≈ 5.3 MB/日
+```
+
+デフォルト設定の30日間保持の場合は **159 MB** 程度になります．
+
+```text
+5.3 MB × 30日 = 159 MB

+## Grafana Loki での可視化

+JSON 形式のため，Promtail を使用し，Grafana Loki にチャンネルチャットのログを取り込むとパースされ読みやすくなります．
