golang monitoring

most common load-balancing mode, but there are several points that need to be supported:1. Support different scheduling strategies, such as: rotation, random, Iphash2. To have a heartbeat check mechanism, timely remove the problematic backend server, but also to recover at the time of server recovery3. Simple monitoring, easy to see the backend Server Agent situation and the client connection situation4. Configuration of parameters, easy to modify5 .

Analyze the implementation of erlang process monitoring and erlang Process MonitoringErlang supports two monitoring methods: Monitor and Link, so that all processes can be integrated. When a process exits due to an error, the monitoring process receives a message indicating that the process exits. With these features, using Erlang to build a simple and robust sys

exit case, we may also be thousands of goroutine. If the Goroutine life cycle gets longer, we will instantly save up 100* thousands of goroutine, and if we don't, our service will crash instantly. So other people's problems may lead to failure of our own services. What to do? Use circuit breaker. We want to protect our services in this way: First set SLA (Service level agreement) Average response time Tolerance Rate Max QPS We need to monitor third-party service invocation error

This is a creation in Article, where the information may have evolved or changed. Before the article, I told a story, I had a friend who used to be a Java programmer, then turned around to do go, and when I asked him why he chose go, he told me that because he wrote go, no one said that he wrote the code low. It's just a joke, don't take it seriously ... Okay, back to the chase. Golang how the network wheel is implemented, first explain what the

Some views on the design pattern of Golang For C, C + +, the object of design exist these several problems 1, the object is dead, only their own properties, behavior (function). There are no mechanisms that can be implemented independently 2, the object is alive, has its own attributes, behavior (functions), as well as independent execution of the activities (their own independent thread). However, due to system constraints, this number of objects

Pure computed observables purely computed monitoring propertiesThe Pure Computational monitoring attribute is introduced in knockout3.2.0, which provides a better choice of speed and memory performance for conventional computational monitoring properties in most cases. This is because the purely computed monitoring pro

Select the major elements of the operations tool: one is to see what indicators I need to monitor, the second is to see what I monitor the third is to see how the operation and maintenance of monitoring tools can be monitored to what extent possible, these problems it OPS personnel did not make it very clear, So let's take a look at the current status of the entire operations industry: at present, the traditional enterprise it operations are mostly u

Comparison between monitoring treasure and zenoss, zenoss monitoring After graduation, I came to my current company and started O M. When we first arrived, our project had only 10 servers, single point mysql server and web server. After nearly three years, the project now has three DataCenter and more than one hundred servers, mysql Sync and more than a dozen web servers between the three DC servers.

Golang Technology (I) in-depth understanding of interface and golanginterfaceRob Pike, one of the major designers of the Go language, once said that if you can only choose one Go language for feature porting to another language, he will choose an interface. It can be seen that the status of the interface in golang and its vitality to the gloang language. What interfaces are in

The ingenious combination of Docker and Golang "Editor's words" This is a simple repertoire of tips and tricks that show how to make Docker more useful when using the go language. For example, how to use different versions of the Go tool chain to compile go code, how to cross compile to a different platform (and test results!). Or how to make a really small container image. The following article assumes that you have installed the Docker. It doesn't

The example of this article describes the Golang implementation of a simple UDP protocol server and client. Share to everyone for your reference, specific as follows: In fact, UDP does not have any server and the concept of the client, just a send a collection, just so more convenient to identify and understand. Service side: Copy Code code as follows: Package Main Import ( "FMT" "NET" ) Func Main () { Create a listener Socket, ERR

The exclusion of spelling and grammar was criticized by them, mainly because many friends felt that I had not made things clear. So I'm going to talk about this in my native language, but when will these international friends learn to read Chinese? ；） Go or Golang is a fast, consistent, and stable open-source programming language supp

Recently in tinkering with the implementation of the Golang daemon, I have no intention of discovering supervisor this interesting thing. Supervisor is a UNIX system process management software that can be used to manage Apache, Nginx and other services, if the service hangs can let them automatically restart. Of course, can also be used to implement the Golang daemon, the following describes the implementa

In the previous article, "Using Golang to design our Ubuntu scope," We've covered how to use Golang to develop Ubuntu scope. In today's article, let's take a brief look at how to use Golang to develop QML applications. This is a good choice for some of the familiar Golang languages, but not very familiar with C + + dev
