これは、CSS と JS 拡張機能とカスタム ビジュアライゼーションを使ったシンプルな XML 機能の一部をデモするために作成されたアプリです。
使用しているデータはほとんどがSplunkの index=_internal から作成されたもので、デモのみを目的としています。

default/data/ui/
    nav
        default.xml - アプリのナビゲーションは4つのダッシュボードのみを表示し、アプリにテーマカラーを与えます。
    views
        overall_health.xml - しきい値チャートを開くためのドリルダウン機能を備えた、要素とサービスのヒートマップとサービスツリービュー。
        health_comparison.xml - 凡例の系列比較にCSSをオーバーライドしたSimpleXMLのチャートを使用したダッシュボード。
        service_flow.xml - ダッシュボードにデータアイコンとカラーを含む画像オーバーレイ用のSimpleXMLでCSS拡張機能を追加しました。
        advanced_view.xml - SimpleXMLにおいてCSSとJavaScriptでモーダルウィンドウのチャートや表を使うための高度なダッシュボード.
    panels
        pp_SplunkNavBarTabView.xml - ダッシュボードメニューがタブとして表示されるようにCSSを上書きするための構築済みパネル（dashboard.cssに移動する必要があります。)
appserver/static/
    scripts
        advanced_model.js - SplunkJSのコードを使ったSimple XML JS拡張用JavaScript
        table_with_tooltip.js -  テーブルヒートマップのツールチップとテーブルタイルアイコンの切り替えに必要なJavaScript
    imges
        svg
            online_shopping_design.svg - SVG background image for Glass Table Dashboard for Image Overlay.
            conf20-nav-logo.svg - SVG logo for Splunk conf20.
        png
            dashboard-background.png - PNG background image for image overlay example.

Dependencies:
    Status Indicator Custom Viz - Used for Font-Awesome Icons - https://splunkbase.splunk.com/app/3119/

          }
          /* Tab View CSS Style - END */
        </style>
      </html>
</panel>

最初のdivは
AppNav.png
の緑色のところ。結構見つけるのが大変だった。
次のdivは角ボタンを角を丸くしてCSSで記述している。

すべて、makeresultsを使ってデータを作成している。Splunk謹製のダッシュボードは_(フィールド名)を使って、表示させないことを結構つかっているな〜という印象。
$tokHosts$ $ICON_COMPUTER$はダッシュボードの最初の方でinitで定義されている。

color

network diagram vizであればcolor region chart vizであればregionで色を指定するので、このように指定している。

region_chart_viz.spl

count>=60 AND count<75, "#F8BE34",
true(),"#B6C75A")

解説

何やっているのかちょっとわからなかったので、

overall_health.xml
<form hideSplunkBar="true" hideTitle="true" theme="dark" >
  <!-- script="/scripts/table_with_tooltip.js" -->

といったんコメントアウトして、splunkを下記の方法で再起動してみる。
http://your_splunk:your_port/ja-JP/debug/refresh?entity=admin/views

Font Awesomeが表示されなくなり、マウスを上にやってもtooltipが表示されなくなった。

tooltip用なのねということで、細かいところは下記の通り。

JQueryについては、たぶんここ

:sweat_smile: JQueryとSplunkJSをまとめて説明できる技能はありません。

テーブルをタイル表示にする、CSS

このテーブルがタイル表示になるという・・・

condition
          <!-- Mimics heatmap view -->
          <condition value="xsmall">
            <set token="tokIconFontSize">0%</set>
            <set token="tokLabelFontSize">initial</set>
            <set token="tokTileWidth">8px</set>
            <set token="tokHideKPIName">none</set>
            <set token="tokHideHost">none</set>
            <set token="tokHideKPI">none</set>
          </condition>
          <!-- Mimics Tile view -->
          <condition value="small">
            <set token="tokIconFontSize">100%</set>
            <set token="tokLabelFontSize">100%</set>
            <set token="tokTileWidth">80px</set>
            <set token="tokHideKPIName">initial</set>
            <set token="tokHideHost">initial</set>
            <set token="tokHideKPI">initial</set>
          </condition>

Gridと｀Tile`の切替でCSSのパラメータを上記の通り変更している。

            #table_tile table tbody{
              display:flex;
              flex-wrap: wrap;
            }

で表の列を横に並ぶようにして、大きさやフォントの大きさを変えることによって多数のステータスを表示している。

元ネタ。自分にとっても思い出深いです。

まとめ

Splunk Dashboards app (beta)が出てきて、実際はCSSとかいじらなくても、いろいろとできるようになっています。

でも、細かい設定をいじるとなるとまだSimpleXMLのほうがやりやすいかな〜と思います。

このAPPSはいろいろなSimpleXMLのテクニックが詰まっているので、是非ダウンロードしていろいろと見てもらいたいと思います。

このItsy Bitsy App for Splunkは@niketnilayがSplunk Answersで色々と回答してきたことをまとめたようなAppsで、自分も.conf20で発表があるということでとても楽しみでした。

直前に悲報があってNiket NilayのすばらしいdashboardやテクニックはSplunk Answersやwikiに残るものが全てとなってしまいました。

初心者を卒業した後Splunkで勉強することを質問した時とかいろいろと教えてもらいました。心の師匠です。少しずつでも、CSSやJSを勉強していきたいと思います。
