通过简单了解了Taint(污点)和 Toleration(容忍)作用,我们既可以通过设置tolerationSeconds来缩短等待时间,也可以自行定义匹配规则实现符合实际情况的调度规则。 另外还要注意先重建再终止和先终止再重建,在此过程中服务启动时间和探针检测时间决定你的服务中断时间。
If your node is in the MemoryPressure, DiskPressure, or PIDPressure state, you must manage your resources in order to schedule extra pods on the node. If your node is in NetworkUnavailable mode, you must configure the network on the node correctly....

vm.vfs_cache_pressure1 - 100100This percentage value controls the tendency of the kernel to reclaim the memory, which is used for caching of directory and inode objects. vm.swappiness0 - 10060This control is used to define how aggressive the kernel will swap memory pages. Higher values will ...
Small buffers are maintained between each processing element and back pressure is used to ensure that resources are kept reasonably constrained.A parameters object is set up to describe the sources, filters and mux streams that are desired and passed to a function that will create the necessary ...
When queue pressure is high, on the other hand, Piscina will stack tasks up in the internal queue and allocate a Promise for each one. While this prevents Worker threads from going idle, it causes increased latency waiting for tasks to execute as they sit for longer periods of time in the...
microphones acquisition and processing software expansion for STM32Cube PDM to PCM conversion The output of the digital MEMS microphone is a bit stream (1.6 MHz on the BlueTile), where frequency of ones is proportional to the sound pressure level: this is ...
kubelet 定期通过 cadvisor 接口采集节点内存使用数据,当节点短时间内内存使用率突增,此时 kubelet 无法感知到也不会有 MemoryPressure 相关事件,但依然会调用 OOMKiller 停止容器。可以通过为 kubelet 配置--kernel-memcg-notification参数启用 memcg api,当触发 memory 使用率阈值时 memcg 会主动进行通知; ...
