> ----------------------------------------------------------------

> Key: EAGLE-868
> URL: https://issues.apache.org/jira/browse/EAGLE-868
> Project: Eagle
> Issue Type: Sub-task
> Components: App::Hadoop JMX Monitor, Core::UI Engine
> Reporter: Hao Chen
> Assignee: JiJun Tang
> Priority: Minor
> Fix For: v0.5.0
>
>
> *Problem*
> Currently when initially loading hbase metric page, there will be relatively
> long time that the whole metric dashboard is blank, then all charts and data
> are rendered at same time.
> *Improvements*
> * Refactor the metric load logic to : Load metric chart config -> show metric
> chart placeholder (show blank chart with no data) and show "data loading
> icon" for each chart one by one -> load metric data query for each chart ->
> reader metric data into metric chart when response returned and remove "data
> loading icon" one by one.
> * Add "loading-in-progress icon" with appropriate description during any
> long-time actions.
