[tusbar]

Example:

    "log": [
      "Records matched: 1952",
      "Record identifier too short: 3019481",
      "Record identifier too short: 533424",
      "Record identifier too short: 774740",
      "Record identifier too short: 301948",
      "Record identifier too short: 289562",
      "Record identifier too short: 2895621",
      "Record identifier too short: 5334241",
      "Record identifier too short: 30194812",
      "Record identifier too short: WMTS",
      "Harvester report:",
      "{\n  \"finished\": \"2018-06-25T13:46:31.475Z\",\n  \"started\": \"2018-06-25T13:44:43.728Z\",\n  \"duration\": 107.747,\n  \"speed\": 18.1,\n  \"status\": \"successful\",\n  \"total\": 1952,\n  \"matched\": 1952,\n  \"returned\": 1950,\n  \"missed\": 2,\n  \"duplicate\": 0,\n  \"exhaustive\": false,\n  \"recordErrors\": 0,\n  \"typesCount\": {\n    \"MD_Metadata\": 1950\n  },\n  \"erroredPages\": 0,\n  \"returnedPages\": 98,\n  \"compatOptions\": [],\n  \"originalServiceURL\": \"http://geobretagne.fr/geonetwork/srv/fr/csw\",\n  \"redirections\": [\n    \"https://geobretagne.fr/geonetwork/srv/fr/csw\",\n    \"https://geobretagne.fr/geonetwork/srv/fre/csw\"\n  ],\n  \"serviceURL\": \"https://geobretagne.fr/geonetwork/srv/fre/csw\"\n}",
      "Unique records returned: 1931",
      "Ignore statistics:",
      "  * Identifier too short: 9"
    ],

"Harvest report:" and "Ignore statistics:" are categories.
