I was under the impression that the default AlertLevel was ERROR but it may have been changed to SEVERE at some point.
There are two ways to register for Alerts. First way is to get the AlertingService from InternalDistributedSystem and invoke addAlertListener. The second way is to register for JMX notifications on the DistributedSystemMXBean. There are quite a few tests for both within geode-core. It's been several years since I've used Pulse, but I do remember seeing Alerts in Pulse and I don't think it required any additional steps. I'm not familiar with the Pulse code, but I don't see any tests in geode-pulse for Alerts so you may have to do some digging to determine what the current behavior is. If that behavior doesn't match the docs, then I would suspect that you've found a bug. I only see one Alert related bug in Jira: GEODE-5923 <https://issues.apache.org/jira/browse/GEODE-5923> JMX manager receives local Alerts only for the default AlertLevel. -Kirk On Wed, Jun 1, 2022 at 9:49 AM Alberto Gomez <alberto.go...@est.tech> wrote: > Hi again, > > Regarding by previous question, I finally managed to get the alerts in > JConsole after subscribing to the notifications under Gemfire -> > Distributed -> System -> Notifications from JConsole. > > Still, I was not able to see any alerts in Pulse. > > Is there a similar subscription step needed to be done in Pulse in order > for Pulse to show alerts in the Alerts Widget? > > Best regards, > > Alberto > ------------------------------ > *From:* Alberto Gomez > *Sent:* Monday, May 30, 2022 6:15 PM > *To:* user@geode.apache.org <user@geode.apache.org> > *Subject:* Alerts sent by Geode not found in JConsole or Pulse > > Hi, > > According to the Geode documentation ( > https://geode.apache.org/docs/guide/112/managing/management/notification_federation_and_alerts.html) > on System Alert Notifications: > > "System alerts are Geode alerts wrapped within a JMX notification.
