使用阿里云日志服务

最近公司要为新研发的系统使用阿里云日志服务，以便于后期数据的分析与发掘，我很有幸的被选中，对阿里云的日志服务进行了一周的学习与简单的使用。

            String endpoint = "<endpoint>"; //选择与上面步骤创建Project所属区域匹配的日志服务Endpoint
            String accessKeyId = "<your_access_key_id>";  //使用你的阿里云访问秘钥AccessKeyId
            String accessKeySecret = "<your_access_key_secret>"; //使用你的阿里云访问秘钥AccessKeySecret
            String project = "<project_name>";      //上面步骤创建的项目名称
            String logstore = "<logstore_name>";    //上面步骤创建的日志库名称
            //构建一个客户端实例
            SLSClient client = new SLSClient(endpoint, accessKeyId, accessKeySecret);
            //列出当前Project下的所有日志库名称
            ListLogstoresResponse res1 = client.ListLogstores(new ListLogstoresRequest(project));
            Console.WriteLine("Totoal logstore number is " + res1.Count);
            foreach (String name in res1.Logstores)
            {
                Console.WriteLine(name);
            }
            DateTime unixTimestampZeroPoint = new DateTime(1970, 01, 01, 0, 0, 0,DateTimeKind.Utc);
            //写入日志
            List<LogItem> logs = new List<LogItem>();
            for (int i = 0; i < 5; i++)
            {
                LogItem item = new LogItem();
                item.Time = (uint)((DateTime.UtcNow - unixTimestampZeroPoint).TotalSeconds);

            Console.WriteLine("Request ID for PutLogs: " + res4.GetRequestId());
            //等待1分钟让日志可查询
            System.Threading.Thread.Sleep(60 * 1000);

                res2 = client.GetHistograms(new GetHistogramsRequest(project, logstore, from, to));
            } while ((res2 != null) && (!res2.IsCompleted()));
            Console.WriteLine("Total count of logs is " + res2.TotalCount);
            foreach (Histogram ht in res2.Histograms)
            {
                Console.WriteLine(String.Format("from {0}, to {1}, count {2}.", ht.From, ht.To, ht.Count));
            }
            //查询日志数据
            GetLogsResponse res3 = null;
            do
            {
                res3 = client.GetLogs(new GetLogsRequest(project, logstore, from, to, String.Empty, String.Empty, 5, 0, true));
            } while ((res3 != null) && (!res3.IsCompleted()));
            Console.WriteLine("Have gotten logs...");
            foreach(QueriedLog log in res3.Logs)
            {
                Console.WriteLine("----{0}, {1}---", log.Time, log.Source);
                for(int i = 0; i < log.Contents.Count; i++)
                {
                    Console.WriteLine("{0} --> {1}", log.Contents[i].Key, log.Contents[i].Value);
                }
            }
        }
    }
