Customization

You can use a json file to customize the application look and preload formats and filters

• Primary color: RGB tuple (reed, green, blue)
• Formats: List of {alias, regex}
  • The regex is used to format lines into the available columns. To do so you need to capture groups. The valid groups are:
    • DATE
    • TIMESTAMP
    • APP
    • SEVERITY
    • FUNCTION
    • PAYLOAD
• Filters: List of {alias, action, filter}
  • action: One of {INCLUDE, EXCLUDE, MARKER}
  • filter: Dictionary of {column_name: regex and color: RGB tuple (reed, green, blue)}. All fields are optional

Example file json { "primary_color": [0, 225, 255], "formats": [ { "alias": "Default", "regex": "(?P<PAYLOAD>.*)" }, { "alias": "Application", "regex": "(?P<DATE>[\\d]{4}-[\\d]{2}-[\\d]{2} [\\d]{2}:[\\d]{2}:[\\d]{2},[\\d]{3}) - \\[(?P<SEVERITY>[\\w]*)\\] - \\[([ \\w]{4})\\] - \\[(?P<TIMESTAMP>[ \\d]*)\\] (?P<PAYLOAD>.*)" }, { "alias": "System", "regex": "(?P<DATE>[\\d]{4}-[\\d]{2}-[\\d]{2} [\\d]{2}:[\\d]{2}:[\\d]{2}.[\\d]*) \\((?P<APP>[\\w\\d]*)[/ ]?(?P<FUNCTION>.*)\\) (?P<PAYLOAD>.*)" } ], "filters": [ { "alias": "System", "action": "MARKER", "filter": { "app": "system", "color": [100, 100, 0] } }, { "alias": "SIGKILL", "action": "MARKER", "filter": { "payload": "SIGKILL", "color": [255, 0, 0] } } ] }
