v1.5.9

VServer SSH Stats — Release Notes

Fixed

• Fixed a collector crash on Linux hosts whose iptables -S output contains
  only default policy lines and no custom -A rules.
• Default-accept iptables configurations, commonly found on fresh Proxmox VE
  and Synology DSM installations, are now handled as a normal inactive
  firewall state.
• Fixed collector aborts when an apt-daily-upgrade or dnf-automatic timer
  is inactive or unavailable. This restores Linux polling affected by the
  withdrawn 1.5.8 release.
• Hardened optional network, Fail2ban, certificate, backup, and disk-I/O
  collectors so empty optional results do not propagate a failing status to
  the main collector.
• Prevented the misleading powershell: command not found error that could
  surface after the Linux collector stopped before producing JSON output.

Technical Details

The remote collector runs with set -e, so a helper function must return
success when an optional probe has no result. The affected collectors now use
explicit guards and successful return paths. grep -c '^-A' also preserves a
zero rule count without propagating its normal no-match exit code.

Upgrade Notes

No configuration changes are required. Update the integration and reload it
to resume normal polling on affected hosts.
