Logstash

Logstash source type graphs number of hits for a given search string over time, similar to the histogram display in kibana.

target is a search string in Lucene syntax, exactly as it would appear in logstash.

For example:

Dash.stats()
  .config({
    type:     'logstash',
    renderer: 'bar'
  })
  .add(
    {
      title:  'HEAD requests',
      target: '@source_host:prod-fe @source_path:/opt/nginx/logs/access.log @fields.verb:HEAD'
    },
    {
      title:  'GET requests',
      target: '@source_host:prod-fe @source_path:/opt/nginx/logs/access.log @fields.verb:GET'
    },
    {
      title:  'POST requests',
      target: '@source_host:prod-fe @source_path:/opt/nginx/logs/access.log @fields.verb:POST'
    }
  );

Bugs

Logstash requires multiple requests to populate data spanning multiple dates. Until dashiki is modified to support this, only the most recent date's data will be displayed.
