I am trying to use HiddenSearch and HiddenPostProcess in a few places to re-use the same result set, based on the documentation here: http://docs.splunk.com/Documentation/Splunk/latest/Developer/PostProcess
I'm running in to a serious problem, however: the results appear to be truncated, and silently. I'm looking for 24 hours of results and I'm getting about 4.5 hours worth. Is there a way to a) determine if the HiddenPostProcess module really is discarding results and b) increase the limit, if so?
Here's the source I am using:
<module name="HiddenSearch" layoutPanel="panel_row2_col1" autoRun="True">
<param name="search"><![CDATA[
index=foo sourcetype=foo_bar | rex field=_raw "host=\"(?<realhost>[^\"]+)\"" | fields _time, severity, program, message, realhost
]]></param>
<param name="earliest">-24h</param>
<module name="HiddenPostProcess" layoutPanel="panel_row2_col1_grp1">
<param name="search"><![CDATA[
search severity<4 | timechart span=5m count by severity
]]></param>
<module name="HiddenChartFormatter">
<param name="chart">area</param>
<param name="primaryAxisTitle.text">time</param>
<param name="secondaryAxisTitle.text">error count</param>
<param name="legend.placement">none</param>
<module name="JSChart">
<param name="width">100%</param>
<param name="height">300px</param>
</module>
</module>
</module>
</module>
