Flags:
  -h, --help                            Show context-sensitive help.
      --config=CONFIG,...               List of Percona Toolkit configuration file(s) separated by
                                        comma without equal sign. Must be a first flag. Uses default
                                        config file locations if not specified.
      --no-color
      --since=SINCE                     Only list events after this date, format:
                                        2023-01-23T03:53:40Z (RFC3339)
      --until=UNTIL                     Only list events before this date
  -v, --verbosity                       -v: DebugMySQL (add every mysql info the tool used), -vv:
                                        Debug (internal tool debug)
      --pxc-operator                    Analyze logs from Percona PXC operator. Will cause slow
                                        performance on non-k8s setups
      --skip-operator-detection         Skip auto detection of Percona PXC operator logs
      --exclude-regexes=EXCLUDE-REGEXES,...
                                        Remove regexes from analysis. List regexes using
                                        'pt-galera-log-explainer regex-list'
      --merge-by-directory              Instead of relying on identification, merge contexts and
                                        columns by base directory. Very useful when dealing with
                                        many small logs organized per directories.
      --skip-merge                      Disable the ability to merge log files together. Can be used
                                        when every nodes have the same wsrep_node_name
      --grep-cmd="grep"                 'grep' command path. Could need to be set to 'ggrep' for
                                        darwin systems
      --custom-regexes=KEY=VALUE;...    Add custom regexes, printed in magenta. Format: (golang
                                        regex string)=[optional static message to display].
                                        If the static message is left empty, the captured string
                                        will be printed instead. Custom regexes are separated
                                        using semi-colon. Example: --custom-regexes="Page
                                        cleaner took [0-9]*ms to flush [0-9]* pages=;doesn't
                                        recommend.*pxc_strict_mode=unsafe query used"
      --version                         Show version and exit
      --[no-]version-check
