Hi,
I 'm getting crazy with this case. I created groups with Nodes. First time, the group work well, until yesterday when I have to unplug the power source of more than 10 devices. Some node members' status in group get wrong in alert. Whenever one node goes down, but it alerts additional 2 members gone down also. Actually those 2 member are up and working properly. Some alerts still fire and do not reset when all node up. I had to receive some fake alert emails.
Another group also get in this case but with different node members.
I use ${GroupStatusRootCause} to figure out what node in a group down.
Please see my attachment.
Thanks to any ideas.
