Slow disk and retransmissions after OneAgent update

Zimmer

Hello,
Does anyone has this kind of behavior, when OneAgent updated to Version 1.253.245 almost all servers' Slow Disk alarm appeared, from the graph, it wasn't very critical at all, IO increased a bit, and also it didn't affect service at all. After some time we realized that there is also a lot of retransmission packets. We decided to roll back and reinstall the previous version of OneAgent Version 1.251 and boom! all problems solved.
Is there any way to identify somehow the root cause? and where to find logs in dynatrace if the log from the menu doesn't shows anything, there should be some logging of OneAgent from the host itself maybe?

If you had this kind of experience before, please share the steps.
Thanks.

Best regards,
Vakho

Hi, it's no my case, but do you see this in Win and Linux? I suggest also to open a support ticket with this to help you dig a little deeper.

The true delight is in the finding out rather than in the knowing.

Good afternoon,

This unexpected behavior was reported to Dynatrace during the recent rollout of our latest agent version. Dynatrace posted an incident on status.io, which has already been resolved.

This incident was supposed to be fixed with the following OA version: 1.253.245

If you still experience a degradation, please open a ticket in our Support Center.


Thanks
Stefan
