Help understanding kubelet events' messages

I need help understanding a specific thing about kubelet event messages. Here is an example:

6 Unhealthy: Startup probe failed: HTTP probe failed with statuscode: 404

Events emitted by the kubelet seen at 2023-11-09 20:04:37 +0000 UTC since 2023-11-09 20:03:47 +0000 UTC

I’m having trouble making sense of the “Events emitted by the kubelet seen at 2023-11-09 20:04:37 +0000 UTC since 2023-11-09 20:03:47 +0000 UTC” part.

It seems to represent that the corresponding event(s), in this case “Unhealthy: Startup probe…” ocurred 6 times in the 2023-11-09 20:04:37 +0000 UTC to 2023-11-09 20:03:47 +0000 UTC time window.
But that doesn’t seem to make any sense when I look at all the events since I will frequently get two different event messages with overlapping time windows and event count like this:

  • 3 Xxxx at 20:04:37 since 20:03:47
  • 5 Xxxx at 20:04:27 since 20:03:47

A smaller and included time window will read a greater event count.

If anyone can shine a light for me here I would be deeply appreciated.

Thank you all!
