Why Some Developers Keep Coding After 40 and How Grafana Powers Their Monitoring Projects

Contrary to the common belief that a software‑development career ends around age 40, many developers continue coding out of genuine passion. A StackOverflow survey shows only 13% of developers are over 40, yet numerous senior engineers remain active in the field.

Examples such as Rob Fletcher, John Brothers, Roger Whitcomb, Scott Gartner, and Brian Bowman demonstrate that seasoned programmers can stay at the forefront of development, deliberately avoiding managerial tracks to keep coding as their primary occupation.

Dennis, a Dutch technical consultant, embodies this mindset. Although he has stepped back from frontline coding, he still maintains a strong technical focus by contributing open‑source projects on GitHub that combine code with visual aesthetics.

In his professional work Dennis managed several Huawei V3 and Dorado storage systems. Finding the vendor‑provided monitoring tools insufficient, he built custom monitoring solutions using the SNMP standard API and Grafana. The resulting dashboards—named “Huawei OceanStor metrics in Grafana” and “Dorado storage metrics”—are continuously updated on his GitHub repository.

Grafana is an open‑source dashboard tool that lets users create custom reports and visualizations from a variety of data sources such as InfluxDB, Collectd, Graphite, Elasticsearch, Zabbix, and SNMP. It excels at displaying time‑series metrics like CPU and I/O utilization, making it ideal for storage and infrastructure monitoring.

A key feature is Grafana Dashboard Templating, which enables the definition of variables that appear as drop‑down selectors on dashboards. This interactivity allows a single dashboard template to be reused across multiple devices or environments.

While many organizations pair Zabbix with Grafana for data collection and visualization, Grafana does not natively support Zabbix as a data source; users must first create a dashboard, then configure templating to link Zabbix‑derived metrics.

Other tools, such as Kibana—part of the ELK stack (Elasticsearch, Logstash, Kibana)—focus on log analysis and provide their own dashboards. Kibana integrates tightly with Elasticsearch, offering powerful search and visualization for log data, whereas Grafana provides a broader range of chart types and more flexible data‑source plugins.

Both tools have distinct visual styles and strengths, catering to different developer preferences. Grafana’s extensive plugin ecosystem and templating capabilities make it especially suitable for real‑time metric dashboards, while Kibana’s native log‑centric features simplify log‑driven investigations.

The article concludes that when coding becomes a genuine interest, it transforms into a personal “poetry and horizon” for developers, regardless of age. Technical tools like Grafana enable this passion to manifest as concrete, shareable solutions that benefit both individuals and organizations.
