For a chart in a view, is it possible to have the chart's title include data the user has entered into the search form field?
Here's my effort:
<form>
<label>Resource Usage</label>
<fieldset autoRun="true">
<input type="text" token="host">
<label>Host</label>
<default>my_host</default>
<prefix>orig_host="*</prefix>
<suffix>*"</suffix>
</input>
</fieldset>
<row>
<chart>
<searchString>
index=summary
report=hw_use_by_jobs
$host$ |
chart
p50(PercentProcessorTime_max) as "p50 CPU",
stdev(PercentProcessorTime_max) as "CPU stdev",
count as DataPoints
over ConcurrentTasks |
eventstats sum(DataPoints) as Total_DataPoints |
eval "Percent of Time"=100*DataPoints/Total_DataPoints |
fields "ConcurrentTasks" "Percent of Time"
</searchString>
<title>Concurrent Task Rates on $host$, last 30 days</title>
<earliestTime>-30d</earliestTime>
<latestTime>now</latestTime>
<option name="drilldown">row</option>
<option name="showPager">true</option>
<option name="count">15</option>
<option name="displayRowNumbers">false</option>
</chart>
...
The chart's data renders as expected. Unfortunately, the chart's title does not include the user input. Instead, it is literally $host$. Is the search field information even available outside the scope of the <searchString> tag? If so, how is it accessed?
