11/22/2023, 4:14 PMI'm guessing you mean rancher installed on a k3s cluster?
bland-article-62755
11/22/2023, 4:14 PMAnd what do you mean by high?
bland-article-62755
11/22/2023, 4:16 PMTraffic between nodes, if you have Rancher, Longhorn, etc. can be a lot.

11/22/2023, 4:16 PMI'm not sure I can answer this, but I don't think I'd have a shot without knowing more.

11/22/2023, 4:16 PMLike what kind of switch and link do you have?
bland-article-62755
11/22/2023, 4:17 PM1/5/10GB?
bland-article-62755
11/22/2023, 4:17 PMAre they on the same VLAN/Switch?
bland-article-62755
11/22/2023, 4:17 PMDid you verify the trafic isn't leaving the switch?

11/22/2023, 4:21 PMeverything is on k3s
downstream cluster is a completely different network (customer on-prem), it sends a pretty good amount of data toward the rancher that is in our network
check if anybody had a similar thing, at least that can exclude rancher/k3s from the equation

11/22/2023, 4:22 PMwhat's a good amount of data?
bland-article-62755
11/22/2023, 4:23 PMlike how much actual bandwidth?

late-eve-82257
11/22/2023, 4:25 PMcca 3GB per hour

11/22/2023, 4:26 PMdo not expect anything more then basic rancher to downstream communication

11/22/2023, 4:26 PMnothing more should happen

11/22/2023, 5:14 PM833.3 kB/s doesn't seem like a whole lot to me, but it does seem like more than what's needed.

11/23/2023, 3:47 PMcurious about this too. I haven't gotten to analyzing traffic yet, but i flagged it as part of my PoC investigation as well.

11/23/2023, 3:48 PMi am suspecting that this could be some logs open on rancher what take good amount of traffic but no proof for it

11/23/2023, 3:49 PMYeah that's true. There is quite a difference between when the UI is being viewed vs not

11/23/2023, 3:50 PMI'm using the rancher-monitoring chart, so I assumed it was related to that at the time.
