This Article is a continuation of Location Tracking in Splunk
The point here is to drilldown on each unique timestamp in the Followmee data and by clicking at the data, get a map representation on the actual location. This involves using "drilldown" to pass data at click to a timepicker, which makes the map refresh.
Also , the Followmee time is a single timestamp, whereas a search is a date-time range (from → to).
On the right, the source code for the Dashboard is present:
The dashboard contains 2 Time pickers:
One for seleting the date time range for the table data, to click on
One for holding the date time range for the map search
The code for the table:
<table>
<search>
<query>index="followmee" | dedup _time | eval User="Normann" | table _time "Data{}.Latitude" "Data{}.Longitude" User</query>
<earliest>$TableTime.earliest$</earliest>
<latest>$TableTime.latest$</latest>
<sampleRatio>1</sampleRatio>
</search>
<option name="count">100</option>
<option name="dataOverlayMode">none</option>
<option name="drilldown">cell</option>
<option name="percentagesRow">false</option>
<option name="rowNumbers">false</option>
<option name="totalsRow">false</option>
<option name="wrap">true</option>
<drilldown>
<eval token="e">$click.value$ +1</eval>
<set token="form.SelectedDateTime.earliest">$click.value$</set>
<set token="form.SelectedDateTime.latest">$e$</set>
</drilldown>
</table>
In the Drilldown part, we take the date time and add 1 to the time, to get a new date time
Then we pass the date time and the date time added with 1 to the timepicker "SelectedDateTime"
When the "SelectedDateTime" Time Picker has new dates, it will refresh the map due to the searchWhenChanged="true" on it
