So I set up and tried out some related projects. This post is mainly about how to install Kindling and configure Grafana to view Kubernetes network connection data. 1. What Is Kindling Kindling solves the problem of how to observe the network without intruding on the application; its functionality is mainly achieved by exposing kernel events for observation.微信公众号KubernetesKindlingNetworkObservabilityOperationseBPFMonitoringhttps://www.chenshaowen.com/en/blog/how-to-collect-labels-and-annotations-of-kubernetes-objects.htmlThu, 02 Jun 2022 01:00:00 +0000Thu, 02 Jun 2022 01:00:00 +0000https://www.chenshaowen.com/en/blog/how-to-collect-labels-and-annotations-of-kubernetes-objects.html1. Why kube-status-metrics is needed Kubernetes monitoring mainly focuses on two kinds of metrics: Basic performance metrics CPU, memory, disk, network, and so on. These can be collected by deploying node-exporter as a DaemonSet and having Prometheus scrape the relevant metrics. Resource object metrics The replica count of a Deployment, the running state of a Pod, and so on.微信公众号KubernetesMonitoringMetricsCollectionPrometheusOperationsLearningObservabilitykube-status-metricshttps://www.chenshaowen.com/en/blog/the-monitor-of-kubernetes-using-prometheus-grafana.htmlFri, 03 Sep 2021 00:00:00 +0000Fri, 03 Sep 2021 00:00:00 +0000https://www.chenshaowen.com/en/blog/the-monitor-of-kubernetes-using-prometheus-grafana.htmlThe Prometheus community moves so fast that some of the documents I wrote earlier have become outdated. I’ve recently started paying attention to observability again, filling in some of the gaps in my operations knowledge. 1.
