Game server logs are usually ignored until the day you need them: a duplication exploit, a mass item-loss complaint, a ban appeal you cannot adjudicate. By then the relevant window has rolled over and the evidence is gone. This guide sizes log storage for realistic retention periods, shows which streams deserve full fidelity and which can be sampled, and lays out a retentions plan that makes incident reconstruction possible without filling the disk that also holds your world saves.<\/p>\n\n\n\n
What Actually Generates Log Volume<\/h2>\n\n\n\n
Five log streams dominate on a busy game node, and they grow at wildly different rates.<\/p>\n\n\n\n
Game server application log.<\/strong> Chat, joins, deaths, actions. For a modded Minecraft or ARK server this is the largest stream by far, often 200 MB to 2 GB per day at 100 players.<\/li>
Plugin and mod logs.<\/strong> Often unbounded and written on every tick. This is the stream that fills disks at 3 a.m. because a mod logged an error every frame.<\/li>
Kernel and systemd journal.<\/strong> Usually small, occasionally enormous during network faults or OOM events.<\/li>
Network flow records.<\/strong> If you sample flows for attack forensics, plan for 20-60 MB per day per busy node.<\/li>
Proxy and auth logs.<\/strong> Join attempts, IPs, session IDs, and everything you need to trace a ban evasion.<\/li><\/ul>\n\n\n\n
Why Compression and Rotation Change the Maths<\/h2>\n\n\n\n
Game logs are extremely compressible because they repeat identical prefixes and timestamps. Ratios of 8:1 to 12:1 with zstd are normal, which means a modded node producing 1.8 GB a day costs about 5.7 GB per month once compressed. The catch is that a log file being actively written cannot be compressed efficiently, so rotation must happen before compression. Rotate on size or time, never on ‘when the disk is full’. A rotation of 500 MB or hourly, whichever comes first, keeps active files small enough to compress and query quickly.<\/p>\n\n\n\n
Sampling Versus Full Fidelity<\/h2>\n\n\n\n
Retaining everything forever is expensive and, for incident work, unnecessary. The key is deciding which streams must be lossless. Ban-evasion investigations need join and auth events at full fidelity, because IP and session correlation depends on every attempt being recorded. Chat and gameplay actions can be sampled heavily, since a one-in-ten sample still shows the shape of a duplication event. Debug and trace streams should be off by default and enabled only during an active incident.<\/p>\n\n\n\n
Freeze first.<\/strong> Snapshot the log directory read-only so continued writes do not rotate the evidence away.<\/li>
Anchor on a timestamp.<\/strong> Ask the reporter for a rounded time; searching a ten-minute window across compressed files is seconds of work.<\/li>
Correlate three streams.<\/strong> Proxy join logs, gameplay logs and system journal together. Duplication exploits usually show as a mismatch between an apply and an inventory event.<\/li>
Preserve the raw files.<\/strong> Store the incident extract off-node so a re-image does not destroy it.<\/li><\/ul>\n\n\n\n
