Telegraf now collects host filesystem usage ([[inputs.disk]], via a read-only /hostfs mount) and PostgreSQL database + per-table sizes ([[inputs.postgresql_extensible]]) into InfluxDB. Surfaces RIB growth and disk pressure — relevant now that the full-table GoBGP feed has pushed the openbmp DB to ~30 GB. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
