Hello,

I tried to enable PSM for rest interface (as a PoC for PSM) but I am not sure it's working, here it is the how-to I followed:
http://www.opennms.org/wiki/Page_Sequence_Monitor_(PSM)_Setup

and here there is my config:
<service name="URL_opennms_rest" interval="300000" user-defined="false" status="on">
<parameter key="port" value="443"/>
<parameter key="timeout" value="15000"/>
<parameter key="retry" value="3"/>
<parameter key="rrd-repository" value="/opt/opennms/share/rrd/response"/>
<parameter key="rrd-base-name" value="URL_opennms_rest"/>
<parameter key="ds-name" value="http"/>
<parameter key="page-sequence">
<page-sequence>
<page path="/opennms/rest/alarms" ds-name="alarms" port="443" successMatch="alarms" />
<page path="/opennms/rest/acks" ds-name="acknoledgments" port="443" successMatch="acknowledgments" />
<page path="/opennms/rest/nodes" ds-name="nodes" port="443" successMatch="nodes" />
</page-sequence>
</parameter>
</service>

the monitor success but I doubt it is working as expected, I mean going through the 3 urls and collecting the response times.

Specially response times are not being collected, I dump the rrd meant to contain these three values:
rrdtool dump /data/opennms/rrd/response/X.X.X.X/URL_opennms_rest.rrd | less

but as you can see just 'http' is being collected
