The PRTG connector will create duplciate Events if the severity of the event has changedDescriptionWhen using a PRTG connector instance to receive alerts from a Paessler PRTG Network Monitor source, the same Event is generated twice when the severity of the event has changed.Steps to Reproduce Install Event Management plugin, and configure a PRTG connector instance to receive alerts from a Paessler PRTG Network Monitor sourceGenerate an internal event on the PRTG server. Within the collection window, change the severity.Wait for it to be collected and then change severity again.Next collection of the PRTG collector will bring 2 events: the one from Step 3 and the initial event from Step 2. Expected behaviour:Only the event at Step 2 should be collected during the next iteration.Actual behaviourDuplicate events are generated.WorkaroundThis problem is currently under review.

A workaround is possible: Go to Connector Definitions -> PRTGOpen the Javascript to run -> PrtgEvents_JSFind the following script at line 280: if(isInitialized) {// We don't want to collect same event from the previous run so// here we are checking on objid,type_raw,datetime_raw and datetime, and if // they are the same we are skipping this eventif(LAST_EVENT_ID == event["objid"].toString() && LAST_EVENT_TIME == eventTimeDateTimestamp&& LAST_TYPE_RAW == event["type_raw"].toString() && LAST_DATETIME_RAW == event["datetime_raw"].toString()) {return;}} Change the script to: if(isInitialized) {// We don't want to collect same event from the previous run so// here we are checking on objid,type_raw,datetime_raw and datetime, and if // they are the same we are skipping this eventif(LAST_EVENT_ID == event["objid"].toString() && LAST_EVENT_TIME >= eventTimeDateTimestamp&& LAST_TYPE_RAW == event["type_raw"].toString() && LAST_DATETIME_RAW >= event["datetime_raw"].toString()) {return;}}Related Problem: PRB1373893
