Udara Liyanage commented on STRATOS-706:
----------------------------------------
Hi Martin,
The job of the CC is to spawn/terminate instances. AS is the one who
decides when/what to start and when to terminate. So as Nirmal said have a
look at the AS logs in order to find the reason for termination/spawning.

> member terminate event should log reason
> ----------------------------------------
>
> Key: STRATOS-706
> URL: https://issues.apache.org/jira/browse/STRATOS-706
> Project: Stratos
> Issue Type: Bug
> Components: Autoscaler
> Affects Versions: 4.0.0
> Reporter: Martin Eppel
> Fix For: 4.0.1
>
>
> When Stratos terminates a member it must log the reason for it. Ideally the
> logging should be systematic enough so that one can grep for different
> severity, or by member, or by event type or some other useful categorization.
> The justification for this defect is that it will improve greatly debugging
> and troubleshooting capabilities. Without logging it is very difficult to
> debug terminations of members.
>
> For example, consider this sequence in the stratos log file:

> ===================
>
> The problem is that Stratos gives no indication of why it is doing this [1].
> Stratos should be enhanced so that the above message gives some indication of
> *why* the member is being terminated (loss of heartbeats, timeout on port
> knocking etc. etc.). This is needed as apache stratos expands it's user base.
> This issue has high priority as it affects the efficiency of troubleshooting
> and system stability.
