Summary by cubic

Patch release 2.8.5 fixes schema consistency, corrects ProxySQL status metrics, and makes procfile parsing robust for non-seekable files. It also excludes ZFS datasets from disk space charts, cleans up CSV parser config serialization, and prevents container env leakage in edit-config.

• Bug Fixes
  • Health alert schema: use "number" for all time_group_value variants for consistency.
  • ProxySQL collector: map backend status to ONLINE, SHUNNED, OFFLINE_SOFT, OFFLINE_HARD; fixes status metrics.
  • Procfile: reopen non-seekable files on ESPIPE/EINVAL; added PROCFILE_FLAG_NONSEEKABLE.
  • Disk space: skip ZFS datasets; only monitor pools to reduce alert noise.
  • Logs CSV parser: fixed omitempty so empty CSV config fields aren’t serialized.
  • edit-config: ignore container variable from /etc/profile; restore prior value or unset.
  • vnodes schema: allow additional string properties in config_schema.json.
