Entity Framework Extension Series CatalogToday we're going to talk about EF's log records.A good database operation record can not only help you to record the user's operation,should also help you get inefficient statements to help you improve your operational efficiency.Nonsense not much to say that we startedEnvironmental and related technologies the environment and technology used in this paperSystem: WIN7Database: SQL Server2008Related technologies: MVC5 ef6.0+A simple recordFirst, modify th

Improved logging and improved logging Compared with the log records sent earlier, this type separates program record processing from disk write operations. The user code part puts the logs in the queue and notifies the thread to write the logs to the file: 1. Public class: Using System;Using System. IO;Using System. Collections.

Using Global.asax's Application_Error to implement error logging Error log Copy Code code as follows: void Application_Error (object sender, EventArgs e) { Code that runs when an unhandled error occurs Exception ex = Server.GetLastError (). GetBaseException (); StringBuilder str = new StringBuilder (); Str. Append ("\ r \ n" + DateTime.Now.ToString ("yyyy"). MM.DD HH:mm:ss ")); Str. Append ("\ r \ n. Customer information:"); s

Kubernetes Important Concept UnderstandingKubernetes is currently the most mainstream container orchestration tool, the next generation of distributed architecture of the king. 2018 Kubernetes The first version 1.10 has been released. Here's a look at some of the basic concepts of kubernetes.The kubernetes divides the machines in the cluster into master nodes and

Author: Peng Jingtian The node nodes of Kubernetes are composed of Kubelet, Kube-proxy, flannel, dockerd four components, this paper mainly analyzes the functions and principles of kube-proxy components. Pod is the smallest unit of resource allocation in kubernetes and the smallest entity to perform tasks. Each pod has a separate IP on the flannel overlay network. Pod Communication in node nodes is impleme

Basic knowledgeFirst: Docker is an open-source container, in fact this technology is not new. In the early days of Linux, there was a lightweight virtualization system like LXC. Docker is actually just a language to implement. Kubernetes means the helmsman of sailing, it's a powerful orchestration + Monitor + disaster preparedness + load management system for DockerSecond: Kubernetes is a summary and best p

First, IntroductionHeapster is a cluster-wide monitoring and event data aggregator. It natively supports kubernetes and can be run on all kubernetes settings. Heapster is run as a cluster in a group, similar to how any other kubernetes application runs. InfluxDB is an open source database written in go that is designed to handle time-series data with hi

in the previous section we discussed the services running on the Kubernetes architecture Master,This section discusses node nodes. Node is where the Pod runs, Kubernetes supports Docker, Rkt, and other container runtime. The Kubernetes components running on node have Kubelet, Kube-proxy, and Pod networks (such as flannel).KubeletKubelet is the agent of node, and

GlusterFSGlusterfs is an open-source, scale-out file system. These examples provide information about how to allow containers to use glusterfs volumes.The example assumes that you have set up the Glusterfs server cluster and is ready to use the running Glusterfs volume in the container.PrerequisiteThe Kubernetes cluster has been built.Installation of the Glusterfs clusterEnvironment IntroductionOS System: Centos 7.xGlusterfs of two nodes: 192.168.22.2

The timing of Nginx Access logging and nginx Logging Take it for granted, so I made a low-level mistake... Nginx access logs can record nginx access information, including the request address, Request Path, return code, and request processing time .. Then the question arises: When did this log be recorded? Is the request recorded at nginx, or is it recorded only after all the requests are processed? Thi
