The Grafana LGTM stack \u2014 <strong>Loki<\/strong> (log aggregation), <strong>Promtail<\/strong> (log agent), and <strong>Grafana<\/strong> (visualization) \u2014 offers a lightweight alternative that runs comfortably on a 1\u20132 GB VPS while indexing gigabytes of logs per day.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide covers deploying Loki + Promtail + Grafana on a single VPS.
