microservice discovery

Microservice monitoring based on five principlesGuideOur requirements for microservices can be summarized into one word: speed. This demand for faster provision of fully functional and reliable software completely changes the software development model. There is no doubt that this change has an impact on software management, including the way systems are monitored. In this article, we will focus on the major changes that need to be made to effectively

Based on the. net core microservice framework and the. netcore framework1Preface Surging uses high-performance RPC remote service calling. If json.net is used for serialization, the performance will not reach the optimal level. Therefore, protobuf and messagepack serialization components are extended to support RPC binary transmission. Thanks to the White Paper and wordless Zonciu, messagepack serialization is added, which makes the surging performanc

Based on the. net core microservice framework and the. netcore framework1Preface Surging has suffered a lot. I also raised a lot of questions regarding the favor of the net students. The most important question is when to integrate API gateway. Here, I will answer the question that we have recently started research and development, there should be an API gateway of the first version within one or two months. Other functions such as Token Authenticatio

First, let's figure out a few things:1. What is the Monitored object?2. What are the monitoring metrics?3. What are the dimensions for monitoring?Monitored object1. User-side monitoring: monitoring of service functions provided to users2. interface monitoring: RPC interface monitoring on which business functions depend3. Resource Monitoring: monitoring of resources on which interfaces depend4. Basic monitoring: monitoring of the health status of the server itselfMonitoring metrics:1. Request vol

Based on the. net core microservice framework and the. netcore framework 1Preface I was surprised to hear that surging has received such strong attention. For example, some colleagues shared surging at the company's sharing conference, and other RPC frameworks and microservices on the blog, these actions make me feel a lot of pressure. After all, as an individual open-source project, it cannot be compared with a mature open-source community project, o

Run the MongoDB microservice on Docker and KubernetesGuideDocker is an open-source application container engine that allows developers to package their applications and dependencies to a portable container and then publish them to any popular Linux machine, you can also achieve virtualization. Containers fully use the sandbox mechanism and do not have any interfaces between them. This article describes how to use Docker and Kubernetes to build a set

SpringCloud microservice architecture-based Hystrix circuit breaker, springcloudhystrix I. What is Hystrix? In a distributed environment, some of the Service dependencies inevitably fail. Hystrix is a database that helps you control the interaction between distributed services by adding latency tolerance and fault tolerance logic. Hystrix isolates access points between services, stops cascade failures, and provides rollback options to improve the over

Spring cloud builds the microservice architecture GateWay (API GateWay), springcloud Preface As mentioned in our previous blog, when service A needs to call service B, it only needs to obtain the registered instance of Service B from Eureka and then use Feign to call service B, ribbon is used to achieve load balancing. However, when we expose multiple services to the client at the same time, how does the client call our exposed services? If we want to

LindDotNetCore ~ Ocelot implements the microservice gateway, Back to directory The Gateway has its own definition in the hardware, and the software architecture also has its own explanation. It is the entrance to all requests, and requests are routed to the gateway for processing and processing, return to the client. In this process, the core of the gateway is the core of Ocelot. We can implement user authorization, verification, caching, authenticati

So far, the rabbitqm service has been successfully started

the POST into objects, while Response.asjson () supports serializing the object into a JSON string without any force.In addition to the above-mentioned simplicity, Nancy also supports many web site standard functions such as: identity verification, beforerequest/onerror events, customized bug pages ... And even with Razor to write a View, it's not difficult to make a Web site that does not iis+asp.net MVC. But according to my strategy, the complex web site will still choose to use ASP. NET MVC,

1. Timeout: for example, the order service calls the product-service interface of the commodity service for order-service: This interface requires a certain amount of response time. This exception occurs when you call it. Solution: In the order-service configuration file application. yml, set the timeout time: Timeout Configuration:The default optons readtimeout value is 60, but because hystrix times out in 1 second by default, response timeout in 1 second is Server: Port: 8781 # specify the Re

Thinking Analysis: Automatic discovery is actually the server's discovery rule in effect, found that the rule is responsible for detecting the host, detect the trigger action Action,action start Add host, add Host template event, if the server detects the host offline, then the discovery rules trigger another action, the implementation of removing the host , so h

Service Discovery With the increasing popularity of micro-services, after the system split, the various service modules between the provider and consumer need to be able to find each other, we call service discovery. In soa/distributed systems, services need to find each other. i.e. a Web service might need to find a caching service, etc. DNS can be used for this but it's nowhere near flexible enough for s

Using Network Service Discovery, showed you how to discover services that are connected to a local network. however, using Wi-Fi Direct trad; Service Discovery allows you to discover the services of nearby devices directly, without being connected to a network. you can also advertise the services running on your device. these capabilities help you communicate between apps, even when no local network or hot

Due to the independent development of xmzoomeye-agent currently passive monitoring mainly, in order to achieve Zabbix low-level discovery service independent discovery, need to automatically obtain the occupied port list according to the process name, and report data according to the port analysisImplementation ideas:1.

Zabbix Automatic Discovery (Discovery) Feature usage With the monitoring host increasing, sometimes need to add a number of machines, especially the children's shoes just with Zabbix need to add all the company's servers to Zabbix, if using traditional methods to add devices, groups, projects, images ... the result should be the result of vomiting. In view of this problem we can make good use of a
