Oh well, I'm sorry but I take it back, seems like we can't stop the loop, even with the Log4j approach we are still getting thousands of events. More than 24,000 in a couple of hours. Most of them are like this:

ERROR 2019-10-29T11:44:19,621 (com.infiniteautomation.mango.slack.event.SlackMessageEventHandlerRT.postMessage:145) - Slack message failed to send java.net.ConnectException: ratelimited at com.ullink.slack.simpleslackapi.impl.SlackWebSocketSessionImpl.connectImpl(SlackWebSocketSessionImpl.java:338) ~[?:?] at com.ullink.slack.simpleslackapi.impl.SlackWebSocketSessionImpl.connect(SlackWebSocketSessionImpl.java:292) ~[?:?] at com.infiniteautomation.mango.slack.event.SlackMessageEventHandlerRT.postMessage(SlackMessageEventHandlerRT.java:122) ~[?:?] at com.infiniteautomation.mango.slack.event.SlackMessageEventHandlerRT.eventRaised(SlackMessageEventHandlerRT.java:67) ~[?:?] at com.serotonin.m2m2.rt.EventManagerImpl.handleRaiseEvent(EventManagerImpl.java:1048) ~[mango-3.6.4.jar:?] at com.serotonin.m2m2.rt.EventManagerImpl.raiseEvent(EventManagerImpl.java:243) ~[mango-3.6.4.jar:?] at com.serotonin.m2m2.rt.event.detectors.PointEventDetectorRT.raiseEvent(PointEventDetectorRT.java:43) ~[mango-3.6.4.jar:?] at com.serotonin.m2m2.rt.event.detectors.PointChangeDetectorRT.pointChanged(PointChangeDetectorRT.java:54) ~[mango-3.6.4.jar:?] at com.serotonin.m2m2.rt.dataImage.DataPointRT$EventNotifyWorkItem.execute(DataPointRT.java:817) ~[mango-3.6.4.jar:?] at com.serotonin.m2m2.rt.maint.BackgroundProcessingImpl$RejectableWorkItemRunnable.run(BackgroundProcessingImpl.java:632) ~[mango-3.6.4.jar:?] at com.serotonin.timer.Task.runTask(Task.java:179) ~[mango-3.6.4.jar:?] at com.serotonin.timer.TaskWrapper.run(TaskWrapper.java:23) ~[mango-3.6.4.jar:?] at com.serotonin.timer.OrderedThreadPoolExecutor$OrderedTaskCollection.run(OrderedThreadPoolExecutor.java:336) ~[mango-3.6.4.jar:?] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) ~[?:1.8.0_172] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) ~[?:1.8.0_172] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_172]

Couldn't find out what is triggering these changes that raise the event detector.

Tried turning off the "Error" data point but now the "Warning" one is also sending weird messages, like this one:

WARN 2019-10-29T12:01:45,429 (com.serotonin.m2m2.web.dwr.MiscDwr.jsError:167) - Javascript error Description: Error: Tried to register widget with id==chartRendererSelect but that id is already registered Page: line 345 > Function line 3 > eval Line: 2 Browser name: Firefox Browser version: 71 osName: Windows location: @ Oct 29, 2019 12:01 PM

We are getting this message when we try to edit the Log4j data points in the old UI (so we can access the event detectors and the purge now button). Explanation below:

Strangely, when we try to edit the data source in the old UI, the "Data points" tab is not existent inside the data source. So I look for the points in the global "Data points" tab, where all data points appear, I filter them by name to find the Log4j Slack Messages Data Points, but most times, when I click the edit (pencil) button on any of the 4 data points, I only get the above "Warning" message in Slack and this same message on a blue box in the old UI:

Error: Tried to register widget with id==chartRendererSelect but that id is already registered

It works super randomly; I seldom get to edit the data point. It's a strange behaviour, something I never saw before with any other data source. I did add the line @terrypacker suggested in the log4j2.xml, inside the loggers section, and restarted it btw.

Is there a quick fix to this? Thanks!
