Gemini gave my Plex server a checkup. Its diagnosis surprised me

AI-Powered Plex Checkup Uncovers Hidden Server Issues

When it comes to streaming your personal media collection, Plex has long been the go-to solution for tech-savvy users who prefer hosting their own content rather than relying on subscription services. But like any server software running 24/7, your Plex installation needs regular maintenance—and thanks to modern AI, that checkup just got a whole lot smarter.

The Setup: A Plex Server Running on Raspberry Pi 5

For years, I’ve been running a Plex server on a Raspberry Pi 5, handling my growing library of movies, TV shows, and home videos. While the setup has been mostly reliable, I realized I hadn’t performed a proper system diagnostic in quite some time. Sure, everything seemed to be working fine on the surface, but that’s exactly when you should be most concerned—silent failures are often the most dangerous kind.

The Problem: I’m No Video Transcoding Expert

Here’s the thing about Plex: it’s deceptively complex under the hood. I can organize my media libraries and understand basic concepts like MKV containers, but when it comes to video transcoding, network optimization, and server performance tuning? I’m completely out of my depth. I needed expert-level analysis without having to become an expert myself.

The Solution: AI as Your Personal Plex Technician

Enter artificial intelligence. While LLMs like ChatGPT, Claude, and Gemini have their limitations—they’re notoriously bad at creative writing and life coaching—they excel at pattern recognition and analyzing large volumes of technical data. For a Plex checkup, that’s exactly what we need.

I chose Google’s Gemini AI, specifically using the Google Antigravity IDE, which allows AI to interact directly with your system files and execute commands under your supervision. This isn’t just asking an AI to interpret log files you copy-paste; it’s giving the AI the ability to explore your Plex installation autonomously.

How the AI Plex Checkup Works

The process begins with a simple prompt: “Can you give my Plex server a check-up?” From there, the AI creates a comprehensive diagnostic plan covering:

• System vitals (CPU temperature, memory usage, storage availability)
• Plex log analysis across multiple log files
• Database integrity checks
• Transcoding performance testing
• Network connectivity assessment
• External storage drive health verification

The AI then executes this plan systematically, requesting approval before each potentially risky operation. For my Raspberry Pi setup, this meant analyzing everything from system logs to Plex’s internal database files.

The Diagnosis: Better Than Expected, With One Critical Finding

After about five minutes of analysis, Gemini delivered its verdict: my Plex server was in “peak athletic condition” overall, but it had discovered something alarming—evidence of a failing SD storage card. This was particularly surprising because I thought I had already migrated from the fragile SD card to a more robust NVMe storage module months ago.

The AI’s initial hypothesis suggested my Raspberry Pi might still be using the SD card for bootup tasks, which would explain the I/O errors flooding the logs. This was concerning because SD cards are notorious for failure in continuous-use scenarios like media servers.

Getting a Second Opinion: Claude Confirms the Diagnosis

Like any good patient seeking medical advice, I wanted confirmation before taking drastic action. I fed Gemini’s findings to Claude Opus 4.5, another advanced AI model, and asked for its assessment. Claude’s analysis provided crucial context: my Pi was indeed booting from the NVMe drive as expected, but the still-connected SD card was being checked periodically, generating the I/O errors.

This was a classic case of the AI seeing warning signs and jumping to conclusions—not incorrect, but not the full story either. The SD card wasn’t actively being used for critical operations, but its presence was still causing system noise.

The Final Verdict: B+ with Actionable Recommendations

With both AI models having weighed in, Gemini provided its final assessment: B+ overall. The server’s vitals were excellent, the transcoding pipeline was healthy, but that old SD card needed to be removed immediately. It also recommended clearing Plex’s transcoder cache to eliminate any potential buffering issues.

Why This Matters: Preventive Maintenance for Your Media Server

This experience demonstrates how AI can serve as an invaluable diagnostic tool for home server administrators. Rather than waiting for a catastrophic failure or spending hours learning the intricacies of Plex’s internal workings, you can leverage AI’s pattern recognition capabilities to identify issues before they become problems.

The beauty of this approach is that it’s accessible to users of all technical levels. You don’t need to understand what every log entry means or how to interpret system metrics—the AI does that for you and presents the findings in plain English.

The Future of Home Server Administration

As AI models continue to improve, we’re likely to see more sophisticated diagnostic tools emerge for home server software. Imagine AI that not only identifies problems but can automatically implement fixes, optimize configurations based on your usage patterns, or even predict hardware failures before they occur.

For now, though, a periodic AI-powered Plex checkup is an excellent way to ensure your media server continues running smoothly, giving you peace of mind that your precious movie collection is being served reliably to all your devices.
