KibanaのグラフのY軸の下限値・上限値を任意の値にする

Kibanaを導入してログの分析をしているのですが、

たまに異常値を記録しそれによってグラフの上限値が引っ張られて見づらくなるので、

上限値を任意の値にしてグラフを見やすくしてくれと言われたので調べてみました。

異常値を記録すると1本のログのせいで全体が小さくなって本来見るべき部分が見づらくなってしまいます。

そこで、Y軸の表示設定を変更します。

  1. 「Metrics & Axes」を選択
  2. Y-Axesの「LeftAxis-1」の▶を選択
  3. 「HideAdvanced Options」の▶を選択
  4. Custom Extentsの「Set Axis Extents」にチェックをいれ、「Max」と「Min」を任意の値に設定します
  5. 「Apply Changes」ボタンを選択し、グラフを再描画すれば任意の値に設定された範囲のグラフが表示されます

Bir takım bilgiler.

Elasticsearch update field for all documents

Elasticsearch is open-source and NoSQL based distributed search engine which is written in JAVA.

It is designed for high-performance searches on large data.

For data storing it uses indexes which is the collection of different types of document and properties.

Compares to the relational database is very fast.

  • A relational database consists of –
    Databases -> Tables -> Row/Columns
  • But the Elasticsearch consists of –
    Indices -> Types -> Documents with properties

To communicate with it requires REST APIs.

It is supported by various languages – JAVA, PHP, Python, JavaScript, Node.js and many others.

In this tutorial, I am using XAMPP for its installation.
