{/// summary/// 服务报警/// /summarypublic class AlertList{public string ServiceName { get; set; }public ListAlertItem Alerts { get; set; }}/// summary/// 报警条目/// /summarypublic class AlertItem{public string TraceID { get; set; }public long StartTime { get; set; }public long Duration { get; set; }public string Method { get; set; }public string Operation { get; set; }}/// summary/// 服务数据/// /summarypublic class ServicesData{public string[] Data { get; set; }public int Total { get; set; }public int Limit { get; set; }public int Offset { get; set; }}/// summary/// 跟踪数据/// /summarypublic class TracesData{public TracesItem[] Data { get; set; }public int Total { get; set; }public int Limit { get; set; }public int Offset { get; set; }}/// summary/// 跟踪条目/// /summarypublic class TracesItem{public string TraceID { get; set; }public Span[] Spans { get; set; }}/// summary/// Span/// /summarypublic class Span{public string TraceID { get; set; }public string SpanID { get; set; }public bool IsAlertMark TraceID SpanID;public int Flags { get; set; }public string OperationName { get; set; }public long StartTime { get; set; }public long Duration { get; set; }public Tag[] Tags { get; set; }}/// summary/// Tag/// /summarypublic class Tag{public string Key { get; set; }public string Type { get; set; }public string Value { get; set; }}
}
这里简单进行了收集转换成了自己的数据集合方便对接自己的报警平台using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Logging;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Threading.Tasks;namespace JaegerAlert.Controllers
{[ApiController][Route([controller])]public class HomeController : ControllerBase{private readonly IHttpClientFactory _clientFactory;private readonly ILoggerHomeController _logger;public HomeController(ILoggerHomeController logger, IHttpClientFactory clientFactory){_clientFactory clientFactory;_logger logger;}[HttpGet]public async TaskIEnumerableAlertList Get(){_logger.LogInformation(获取警报列表);return await GetServices();}/// summary/// 获取所有服务/// /summary/// returns/returnsasync TaskIEnumerableAlertList GetServices(){var service await GetJaegerServices();var services new ListAlertList();foreach (var serviceName in service.Data){if (serviceName jaeger-query){continue;}var alerts new ListAlertItem();var tracesModels await GetJaegerTraces(serviceName);foreach (var traces in tracesModels.Data){foreach (var span in traces.Spans){if (span.IsAlertMark){var method span.Tags.SingleOrDefault(s s.Key http.method)?.Value;var operation span.Tags.SingleOrDefault(s s.Key http.url)?.Value;alerts.Add(new AlertItem { TraceID traces.TraceID, Duration span.Duration, Method method, Operation operation, StartTime span.StartTime });}}}services.Add(new AlertList() { ServiceName serviceName, Alerts alerts });}return services;}/// summary/// 获取服务下的跟踪条目/// /summary/// param nameserviceName/param/// returns/returnsasync TaskTracesData GetJaegerTraces(string serviceName){using var client _clientFactory.CreateClient(Jaeger);var request new HttpRequestMessage(HttpMethod.Get, $/api/traces?service{serviceName});using var response await client.SendAsync(request);if (response.IsSuccessStatusCode){var jsonString await response.Content.ReadAsStringAsync();var traces Newtonsoft.Json.JsonConvert.DeserializeObjectTracesData(jsonString);return traces;}else{return new TracesData();}}/// summary/// 获取服务/// /summary/// returns/returnsasync TaskServicesData GetJaegerServices(){using var client _clientFactory.CreateClient(Jaeger);var request new HttpRequestMessage(HttpMethod.Get, /api/services);using var response await client.SendAsync(request);if (response.IsSuccessStatusCode){var jsonString await response.Content.ReadAsStringAsync();var service Newtonsoft.Json.JsonConvert.DeserializeObjectServicesData(jsonString);return service;}else{return new ServicesData();}}}
}
请求结果收集到数据后就可以应用到报警平台上如果报警平台有api可以进行调用处理还可以把这些数据推送到时序数据库中如InfluxDB再通过Grafana展示出来进行实时展时跟踪关于跟踪的细节和业务规则有关系如果以后工作中遇到这类处理到时再追加一篇博文进行细说。
