openQA Project - coordination #108209: [epic] Reduce load on OSD
After switch to nginx on OSD let's investigate how system performance was impacted
0%
Description
Motivation¶
After switch to nginx on OSD let's investigate how system performance was impacted. We shouldn't wait too long to still have fresh data with sufficient resolution available.
Acceptance criteria¶
- AC1: We know the system performance impact before vs. after based on monitoring data
Suggestions¶

Looking at https://monitor.qa.suse.de/d/WebuiDb/webui-summary?orgId=1&from=1714772555160&to=1715761728305 . The time period is 2024-05-04 to 2024-05-08 running apache2 and then 2024-08-09 to 2024-05-15 running ningx, correlating with #130636-22. It's visible as expected that apache data is only available until 2024-05-08. There is no significant change in memory usage, inode or file system usage, system load, cpu usage or http response. The only change seems to be that the ping time slightly increased in that period which is curious. So I guess that means that there is no significant impact of the switch to nginx in neither a negative or positive way. With that we can keep nginx and need no further changes related to system performance impact. Let's see if that helps to prevent http unresponsiveness problems that we want to fix with that.
