--log-level

Die Level sind die gleichen wie BFFH_LOG

Log File schreiben

Wer bffhd nicht über systemd startet und deshalb auch keine Logs in journalctl schreibt, der kann den Output auch in eine Log-Datei schreiben - hier im Beispiel bffh.log. Wir fangen dabei die Output-Streams stdout und stderr gemeinsam ab:ab. Den Parameter --log-level ignorieren wir, da er bei der normalen Systemausgabe ignoriert wird und führen stattdessen mit BFFH_LOG an:

BFFH_LOG=debug /opt/fabinfra/bffh/target/release/bffhd --verbose --config /opt/fabinfra/bffh-data/config/bffh.dhall --log-format Pretty > bffh.log 2>&1
