It&rsquo;s a lot of infrastructure for one person to monitor.</p> <p>I had alerts. Grafana fires when RAM hits 75%. Wazuh flags suspicious file changes. n8n emails me when workflows fail. But alerts are reactive. They tell you something broke. They don&rsquo;t tell you something is <em>about to</em> break.</p>
