Contributed to the influxdata/telegraf repository by implementing disk and network I/O metrics for the Proxmox input plugin, enhancing observability for Proxmox-based deployments. This work involved updating data structures and gathering logic in Go to support the collection and parsing of read/write bytes and network in/out bytes, ensuring accurate reporting of these new metrics. Comprehensive tests and documentation were added to validate the feature and guide users. The integration leveraged API interaction and JSON handling to reliably extract and process operational data, supporting improved capacity planning, anomaly detection, and SLA reporting for users monitoring Proxmox environments with Telegraf.
