Example: Aggregation and Grouping in the Explore Logs Chart
The following table contains examples to illustrate aggregation and grouping in VMware Aria Operations for Logs charts.
|Selection in the First Drop-Down Menu||Selection in the Second Drop-Down Menu||Time series selection||Text Displayed on the Screen||Result|
|Count||Time series||Time series||Count of events over time||The chart displays a bar chart with the number of events for the current query over time.|
|Average||vmw_op_latency (VMware - vSphere)||Time series||Average of vmw_op_latency (VMware - vSphere) over time||The chart displays a line chart with average value of operations latency over time.|
Note: Thevmw_esx_problem field does not appear by default. You must extract the vmw_esx_problem field and save the query so that vmw_esx_problem appears in the drop-down menu.
|Non-time series||Count of events grouped by vmw_esx_problem||The chart displays a bar chart of the number of events for containing the vmw_esx_problem field.|
|Count||Time series, vmw_esx_problem||Time series||Count of events over time grouped by vmw_esx_problem||The chart displays a stacked bar chart grouped by vmw_esx_problem over time.|
