Simple log Viewer Symfony Bundle

LogViewerBundle is a basic log viewer for symfony. It allows you to list and view all of the symfony logs or external logs in one easy place with level highlighting and level filtering.

###Caution: Upgrading from a version older than 1.4 will break your log patterns. See breaking changes below.

Installation

Install the package with:

composer require evotodi/log-viewer-bundle

Suggested Packages

Install nesbot/carbon for datetime parsing and enable in config

composer require nesbot/carbon

evo_log_viewer:
    log_files:
        use_carbon: true

Configuration

Create the routes yaml file config/routes/evo_log_viewer_routes.yaml

evo_log_viewer:
  resource: '@EvotodiLogViewerBundle/Resources/config/routes.xml'
  prefix: '/logs'

Create the config yaml file config/packages/evo_log_viewer.yaml

# List of log files to show
evo_log_viewer:
    log_files:
        # Unique identifier for the logfile
        somelog1:
            # Use full path
            path: 'Some/Full/Path/to/Log/File.Ext'

            # Pretty name to display else file name
            name: My Log Files Pretty Name 

            # (Optional) Number of days to pull from log. See ddtraceweb/monolog-parser.
            days: 0

            # (Optional) See ddtraceweb/monolog-parser for patterns.
            pattern: null

            # (Optional) PHP style date format of log file
            date_format: 'Y-m-d H:i:s'

            use_channel: true

          # (Optional) Use P<level> in the pattern
            use_level: true
            
            # (Optional) Log level spelling. Case sensitive

                alert: ALERT
                critical: CRITICAL
                emergency: EMERGENCY

        somelog2:
            path: '/path/to/logfile.log'
            name: Pretty Logfile Name

    # Show App logs in var/log
    show_app_logs: true
    
    # (Optional) Change the default parser pattern
    app_pattern: '/\[(?P<date>.*)\] (?P<logger>\w+).(?P<level>\w+): (?P<message>[^\[\{].*[\]\}])/'
    
    # (Optional) Change the default date format
    app_date_format: 'Y-m-d H:i:s'
    
    # (Optional) Use nesbot/Carbon for datetime parsing
    # Execute 'composer require nesbot/carbon' before setting to true
    use_carbon: false

Advanced Configuration

pattern

The default pattern is '/\[(?P<date>.*)\] (?P<logger>\w+).(?P<level>\w+): (?P<message>[^\[\{].*[\]\}])/'
You can change the regex pattern to match your log file but the pattern must include P<date>, P<channel>, P<level>, and P<message> as regex groups. You can omit the P<channel> and P<level> by setting use_channel: false and use_level: false respectively.
Example '/\[(?P<date>.+)\] (?P<logger>\w+).(?P<level>\w+): (?P<message>.*)/'
See ddtraceweb/monolog-parser for other examples but ommit P<context> and P<extra>

days

Setting days in the config to 0 will parse to whole log which is the default. Days set to 5 for example will parse the log until the date portion of the pattern if greater than DateTime('now') minus 5 days.

date_format (optional)

This should be the php date format of the date portion of the pattern. Default is Y-m-d H:i:s / PHP DateFormat

levels

Override the default spelling for each level. e.g. WARNING -> WARN

Breaking Changes

Updating from an older version to version >=1.4 will break your log patterns. This is easy to fix, just change P<logger> to P<channel>.
