Hello!

I'm trying to add custom alert filter. I've done it in few ways - via Alert Filter Configuration Tool and via Application Client. In both cases alert.filters was changed like this:


<?xml version="1.0" encoding="ISO-8859-1"?>
<ALERT_FILTERS>
<!--
#
#@(#)../conf/alert.filters
#
# This file was generated by AdventNet NetAlerts.

-->
<FILTER enable="true" name="CustomViewFilter">
<FILTER_ACTION className="com.adventnet.nms.eventdb.UserFilter" name="AlertFilter_4_TL1CustomView" userclass="com.adventnet.nms.eventdb.tl1.TL1EventFilter4CustomView"/>
</FILTER>
<FILTER enable="true" name="AddAlarmStateFilter">
<FILTER_ACTION className="com.adventnet.nms.eventdb.UserFilter" name="AddAlarmState" userclass="demo.AddAlarmStateAlertFilter"/>
</FILTER>
</ALERT_FILTERS>


It seems to be correct configuration, however the filter is not invoked. What are typical reasons of such a problem? I'm expecting that it will be applied to all new alerts generated by WebNMS. I put the demo.AddAlarmStateAlertFilter class in <WebNMS home>/classes folder. It has empty constructor and empty init() function. Do you have any ideas?

Thanks
