CEP seems to be emiting stats even though there are no incoming requests...
$subject.
For e.g. there is no instances in the cluster
"lahiru123.isuruh.lk.php.domain " since the user has unsubscribed.
But Autoscaler has received a stat event [1]..
[1]

Agree with Nirmal.
AS should ignore messages from invalid members
Touched, not typed. Erroneous words are a feature, not a typo.

Posted by Nirmal Fernando <ni...@gmail.com>.
Hi All,
Will someone get concerned after seen a warning or an error, in this case?
IMO if this is of no harm and not require any attention, we could just make
it a debug log. But it really depends on the scenario and we need to
examine.

Re: CEP seems to be emiting stats even though there are no incoming requests...
Posted by Nirmal Fernando <ni...@gmail.com>.
There's a possibility that CEP would emit an event in this scenario (since
CEP aggregates events came in a specific time period). This cannot be
solved at CEP end, I think the solution would be to discard events that are
not relevant at Auto-scaler end. Wdyt?
