Description

Observation

The "Apache Workers" and "HTTP Response" alerts fired on 2023-12-11 00:48:00 +0100 CET and 2023-12-11 00:49:00 +0100 CET respectively. The alerts were resolved 5 minutes later. So the impact is likely not very high (if there was an impact at all).

In https://stats.openqa-monitor.qa.suse.de/d/WebuiDb/webui-summary?orgId=1&from=1702243017076&to=1702261824564 I could see that there was high CPU load, low CPU usage and near-zero I/O bandwidth on all monitored storage devices. So I suspect that the external hypervisor blocked the VM which apparently does not happen often. I see no necessary action here right now.
