Grafana自定义alert的实现过程

不问归期 提交于 2021-02-08 12:27:00
前言 grafana自带的alert功能是有限的,比如只能对某个query 配置alert,而不能对具体分类,当然我们也可以通过代码来实现定制化的alert 因要定时监控grafana的数据变化情况,所以本篇文章使用 easyswoole的定时器 来做讲解。 生成key key为调用grafana http api 所需的验证信息 分析要请求的api和传递的参数 当然你可以去grafana官方文档去翻一番http api 章节 Install easyswoole的http-client组件 easyswoole\http-client composer require easyswoole\http - client easyswoole 定时器 定时器 代码实现 <?php namespace EasySwoole \ EasySwoole ; use EasySwoole \ Component \ Timer ; use EasySwoole \ EasySwoole \ Swoole \ EventRegister ; use EasySwoole \ EasySwoole \ AbstractInterface \ Event ; use EasySwoole \ HttpClient \ HttpClient ; class EasySwooleEvent

Angular error handling and logging - Call GlobalErrorHandler's handleError

◇◆丶佛笑我妖孽 提交于 2021-02-08 10:50:56
问题 I'm following an Angular error handling/logging tutorial here: https://www.code-sample.com/2017/09/angular-4-error-handling-and-logging.html My question is - how can I call the handleError method (residing in the global-error-handler.service.ts file, seen in step 3 below) from one of my services? In my ErrorLogService , I'm also instantiating a POST request (with data coming from a component) and using catchError to try and call handleError from global-error-handler.service.ts , but I'm

.NET Core HttpClient源码探究

蓝咒 提交于 2021-02-07 06:51:34
前言 在之前的文章我们介绍过HttpClient相关的服务发现,确实HttpClient是目前.NET Core进行Http网络编程的的主要手段。在之前的介绍中也看到了,我们使用了一个很重要的抽象HttpMessageHandler,接下来我们就探究一下HttpClient源码,并找寻它和HttpMessageHandler的关系究竟是怎么样的。 HttpClient源码解析 首先我们找到HttpClient源码的位置,微软也提供了专门的网站可以查找.Net Core源码有兴趣的同学可以自行查阅。接下来我们查阅一下HttpClient的核心代码。首先,我们可以看到HttpClient继承自HttpMessageInvoker这个类,待会我们在探究这个类。 public class HttpClient : HttpMessageInvoker { } 然后我们看下几个核心的构造函数 public HttpClient ( ) : this ( new HttpClientHandler( )) { } public HttpClient ( HttpMessageHandler handler ) : this ( handler, true ) { } public HttpClient ( HttpMessageHandler handler, bool

HttpClient executes requests multiple time if request timed out

不问归期 提交于 2021-02-07 03:14:44
问题 HttpClient executes request 4 times if it times out. If it does not time out then it is working fine. Is it related to HttpClient ? 回答1: I found that it is HttpClient 's default behaviour to execute requests 4 times if it fails. I am not sure about other kind of failures but at least with time out. To disable this behaviour do this : DefaultHttpClient client = new DefaultHttpClient(); // Disable default behavior of HttpClient of retrying requests in case of failure ((AbstractHttpClient)

How can I get my upload speed with HttpClient

旧时模样 提交于 2021-02-05 12:14:20
问题 I'm using HttpClient to post a byte array to a server. How can I tell how many bytes are transferred per second? 回答1: The simplest, naive way to do it is to use the Stopwatch class to get the interval before and after your HttpClient.PostAsync call, then divide that time by the payload size: byte[] payload = GetData(); var content = new ByteArrayContent(payload); var stopwatch = Stopwatch.Start(); await httpClient.PostAsync(url, content); stopwatch.Stop(); var bps = payload.Length / stopwatch
