I have a k3s cluster with embedded etcd on ubuntu VM’s. It has 3 master nodes with 6G ram each and another 3 agents with 6G ram each.
It’s pretty much freshly installed, I added logging, longhorn, monitoring and rancher backups from the rancher helms.
After this and after configuring the alerting system I’m getting KubeAPIErrorBudgetBurn - The API server is burning too much error budget.
To be honest is the first time I’m seeing this and I’m not sure what to look for.
This is my API Server graphs which if I understand this correctly ErrorBudget is terrible somehow?
From the home page all seems pretty decent:
I found this online as well: Understanding the KubeAPIErrorBudgetBurn Alert Reason · Issue #464 · kubernetes-monitoring/kubernetes-mixin · GitHub
Looking into it they recomend increasing etcd resources, but I’m not sure how to do so since this is embedded etc and since this is an empty cluster shouldn’t this be fine with a fresh install?
I’m really not sure what to look for so any help here would be appreciated.
