组件监控配置说明

一：Record说明

在这个文件中，我们定义了一个名为node-exporter-rules的Prometheus Rule。它包含一个名为node-exporter.rules的规则组。该规则组定义了一个名为node_filesystem_avail_ratio的指标，并将其记录在Prometheus中

kind: PrometheusRulemetadata: name: node-exporter-rulesspec: groups: - name: node-exporter.rules rules: - expr: node_filesystem_avail_bytes / node_filesystem_size_bytes * 100 < 10 record: instance:node_filesystem_avail_ratio:ratio

二：Kubernetes及相关组件告警规则

Kubernetes及相关组件告警规则，可参考：
