Surya Hebbar has uploaded a new patch set (#7). ( http://gerrit.cloudera.org:8080/20355 )
Change subject: IMPALA-12364: Display memory, disk and network metrics in webUI's query timeline ...................................................................... IMPALA-12364: Display memory, disk and network metrics in webUI's query timeline The fragment's plan nodes are enlarged with an animated transition on hovering over the query timeline's fragment diagram. On clicking the plan nodes, total thread and memory usage of the parent fragment are displayed, after accumulating memory and thread usage of all child nodes. In this way, memory and thread usage of multiple fragments can be compared alongside. A fragment's usage can be hidden by clicking on any of the child plan nodes again. Once a fragment's metrics are displayed, they are updated as they are collected from the profile. A grid-line is displayed along with a tooltip on hovering over the fragment diagram, containing the instantaneous time at that position. This grid-line also triggers tooltips and gridlines in other charts. The thread usage is being shown on the additional Y-axis. A warning is displayed on clicking a fragment with less number of samples available. RESOURCE_TRACE_RATIO query option provides the utilization values to be traced within the RuntimeProfile. It contains samples of disk and network usage on each host. These time series counters are available within the profile having the following names. - HostDiskWriteThroughput - HostDiskReadThroughput - HostNetworkRx - HostNetworkTx The additional Y-axis within the utilization chart is used to represent the average of these metrics. The memory units in tooltips and ticks on co-ordinate axes are being displayed in human readable form such as KB, MB, GB and PB for convenience. Both of the charts contain controls to close the chart. Timeticks are being autoscaled during fragment diagram's horizontal zoom. In addition to the scrollbar, hovering on edges of the window allows horizontal scrolling. For implementing unit and integration tests, the script has been divided into multiple properly functioning modules, that are imported into the webpage.
