Beyond the Dashboard: How a 14B LLM Brought Real Intelligence to My Server Monitoring

Leave a comment

If you manage Linux servers, you already know the morning ritual. You sip your coffee and stare at your monitoring dashboards. Grafana, Zabbix, Datadog – pick your poison. They are excellent at showing you lines on a graph, but let’s be honest; traditional monitoring is fundamentally “dumb.”

Standard monitoring relies on rigid thresholds. If CPU usage hits 95%, you get an alert. But what if that 95% CPU usage is just the scheduled weekly backup running alongside a routine malware scan? Your dashboard doesn’t care. It fires off an alert anyway, contributing to the slow, inevitable creep of alert fatigue.

I wanted something better. I didn’t just want monitoring; I wanted monitoring plus intelligence.

What I Learnt Giving an LLM Agent Control of My Crypto Wallet

UkkoTrader Dashboard Header showing Net Loss from early trades

In my role as a Senior OpenShift Technical Account Manager at Red Hat, I focus on mission-critical stability; helping organisations navigate the shift from cloud-native architectures to AI-ready operations. But there is a distinct difference between advising on a scalable MLOps workflow and trusting a local LLM to trade your own capital in a volatile market.

Would you trust an AI agent with your bank account? I did; and it was a masterclass in ‘Boom or Bust’ logic.

Navigating the Future of Local Development: The Red Hat Build of Podman Desktop

Leave a comment

The “it works on my machine” excuse has officially reached its expiration date. As we move through 2026, the complexity of modern applications – often involving a mix of containers, Kubernetes manifests, and now local AI models – demands a local environment that is not just a sandbox; it is a mirror of production.

Enter the Red Hat build of Podman Desktop.

Docker Panic, CMD and Hashbang

Leave a comment

Noticed issue when rebuilding dockerfile and running image:-

panic: standard_init_linux.go:178: exec user process caused "exec format error" [recovered]
	panic: standard_init_linux.go:178: exec user process caused "exec format error"

goroutine 1 [running, locked to thread]:
panic(0x6f3080, 0xc4201393b0)

Did much digging, identified that when specifying a script as a CMD in the Dockerfile, this script now requires a proper hashbang (aka shebang) or the above panic results.

#!/bin/bash
rm -rf /run/httpd/* /tmp/httpd*
exec /usr/sbin/apachectl -DFOREGROUND

Rebuilding the docker image with –no-cache option ensures the updated file is included.
