use of org.opennms.netmgt.correlation.drools.DroolsCorrelationEngine in project opennms by OpenNMS.

the class DependencyRulesIT method testTwoOutagesTwoResolutionsCase.

// Test two down and two up events where the initial event that caused the propagation is
// resolved but a new component goes down. The expectation is that the service should remain
// down instead of going back up and then down again. This was reproduced with the following :
//echo "Send IfDown and PwDown"
//send-event.pl --parm "jnxVpnIfVpnName ge-1/3/2.1" --parm "jnxVpnIfVpnType 5" -n 5 uei.opennms.org/vendor/Juniper/traps/jnxVpnIfDown

//sleep 10
//echo "Send IfUp and PwUp in same order this causes issue with clearing"
