|
|
Usage: scripts/capture_remote_journal_errors.sh --nodes <csv> --since <iso-time> --label <label> --out-dir <dir> [options]
|
|
|
|
Capture RustFS journal lines matching auth/error/failure patterns for a UTC
|
|
validation window. The --since value is normalized to the journalctl-friendly
|
|
"YYYY-MM-DD HH:MM:SS UTC" form before it is sent to remote nodes.
|
|
|
|
Options:
|
|
--nodes <csv> Comma-separated node names, for example vm004,vm005.
|
|
--since <iso-time> UTC ISO timestamp, for example 2026-08-08T09:05:45Z.
|
|
--label <label> Prefix used for output files.
|
|
--out-dir <dir> Local output directory.
|
|
--unit <name> systemd unit name. Default: rustfs.
|
|
--filter-regex <expr> grep -Ei pattern. Default captures auth/signature/error/warn/fail/panic.
|
|
--ssh-bin <path> SSH binary or test double. Default: ssh.
|
|
-h, --help Show this help.
