“腾讯云日志服务“对接的前前后后

桃扇骨 2022-12-31 01:20 160阅读 0赞

一、绪论

经过几天的探索，终于把"腾讯云日志服务"(使用API的方式)给接上了，为此写上一篇博客来记录我的劳动成果

二、几个概念

（1）、日志集（Logset）

日志集（Logset）是日志服务的项目管理单元，用于区分不同项目的日志。一个日志集对应一个项目或应用，建议将不同项目和不同产品的日志，使用不同的日志集进行管理。例如，某公司有两种业务：电商业务、支付业务，每种业务可以创建一个日志集。

一个日志集可以包含多个**日志主题**，每个日志集有以下基本属性信息：

*  日志集名称：日志集命名。
 *  日志集 ID：标识一个日志集的 ID 编号，全局唯一。
 *  地域：日志集所属**地域**。
 *  存储周期：当前日志集里数据的保存时间周期，可保存时间周期为1 - 90天。

（2）、日志主题（Topic）

日志主题（Topic）是日志服务的基本管理单元，一个 [日志集][Link 1] 可以包含多个日志主题。一个日志主题对应一类应用或服务，建议将不同机器上的同类日志收集到同一个日志主题。例如，一个业务项目有三种日志：操作日志、应用程序日志、访问日志，每种类型可以创建一个日志主题。

日志服务系统以日志主题为单位，区分管理用户不同的日志数据，每个日志主题都可以配置不同的数据源、不同的索引规则和投递规则。因此，日志主题是日志服务配置管理日志数据的基本单元，创建日志主题后需配置相关规则，才能如期有效地进行日志采集，并使用检索分析和投递等功能。

从场景功能上理解，日志主题主要提供：

*  采集日志到日志主题。
 *  以日志主题为单元存储管理日志。
 *  以日志主题为单元检索分析日志。
 *  以日志主题为单元投递日志到其他平台。
 *  从日志主题下载、消费日志。

（3）、日志组（LogGroup）

日志组（LogGroup）是一个包含多条日志的集合。在上传、消费日志的过程中，考虑读写的效率和压力，日志组作为 CLS 基本的数据单元，可将多条日志打包成一个日志组，并以日志组为单位发送到 CLS 。

一个日志组里的日志具有相同的元信息（\_\_FILENAME\_\_、\_\_SOURCE\_\_、\_\_LogTag\_\_等），详细参考上传数据结构 [CLS Protobuf 数据格式][CLS Protobuf]。

相关限制：

*  一个数据包里 [LogGroup ][LogGroup]包含日志条数至少为1条，最多为10000条
 *  LogGroup 所有 Value 大小最大总和为5MB

（4）、机器组（MachineGroup）

机器组（MachineGroup）是一组需要采集日志的机器列表，日志服务通过机器组来管理所有需要通过 [LogListener][] 采集日志的服务器。

一个机器组可以包含多台机器。通常情况下，一类服务应用程序会部署在多台机器上，并且这些机器的日志采集配置相同，可以将其归于同一个机器组，并将该机器组关联到对应的日志主题。一个日志主题可以关联多个机器组，一个机器组也可被关联到多个日志主题。

机器组的定义方式：添加 IP 地址到机器组，通过 IP 地址识别服务器。

三、开始对接API（前奏）

（1）、准备工作

需要获取 SecretId 和 SecretKey

四、创建日志集、日志主题、机器组等

这些可以在腾讯云后台配置，也可使用api的形式，比较简单这里不仔细讲（需要将创建的日志集id和日志主题id放入到项目中）

五、最重要的上传结构化日志（日志主题检索状态必须开启）

（2）、发送结构化日志

         * @param level
         * @param contentStr
         * @param userid
         * @param topicId
         * @return
         */
        public static Integer sendClsStructuredLog(String level,String contentStr,String userid,String loggerName,String topicId) {
            Cls.Log.Builder log = Cls.Log.newBuilder();
            log.setTime(new Date().getTime() * 1000);
            Cls.Log.Content.Builder content = Cls.Log.Content.newBuilder();
            content.setKey("level");
            content.setValue(level);
            log.addContents(content);
            content.setKey("content");
            content.setValue(contentStr);
            log.addContents(content);
            content.setKey("loggerName");
            content.setValue(loggerName);
            log.addContents(content);
            if(StringUtils.isNotBlank(userid)){
                content.setKey("userid");
                content.setValue(userid);
                log.addContents(content);
            }
    
            Cls.LogGroup.Builder logGroup = Cls.LogGroup.newBuilder();
            logGroup.addLogs(log);
            logGroup.setContextFlow("uuid" + new Date().getTime());
            try {
                logGroup.setSource(InetAddress.getLocalHost().getHostAddress());
            } catch (UnknownHostException e) {
                e.printStackTrace();
            }
    
            Cls.LogGroupList.Builder logGroupList = Cls.LogGroupList.newBuilder();
            logGroupList.addLogGroupList(logGroup);
    
            String path = "/structuredlog";
            Map<String, String> header = new HashMap<String, String>();
            header.put("Host", ClsSignatureUtil.Host);
            header.put("Content-Type", "application/x-protobuf");
            Map<String, String> param = new HashMap<String, String>();
            param.put("topic_id", topicId);
            header.put("Authorization", ClsSignatureUtil.getGetPostSignature(param, header, path, "post"));
            return HttpUtil.doPostByClsByte("http://" + ClsSignatureUtil.Host + path, logGroupList, param, header);
        }

说明：

1、必须使用<LogGroupList 的 PB 格式打包内容>

2、使用这种打包方式必须使用二进制流的方式

3、请求的"Content-Type"必须为"application/x-protobuf"

4、使用之前可以学一下PB文件的相关知识

（3）、根据条件检索日志

/**
         * 根据条件检索日志
         * @param logsetId
         * @param topicIds
         * @param startTime
         * @param endTime
         * @param queryString
         * @param limit
         * @return
         */
        public static String searchClsStructuredLog(String logsetId,String topicIds,String startTime,String endTime,String queryString,String limit,String context,String sort) {
            String path = "/searchlog";
            Map<String,String> header = new HashMap<String, String>();
            header.put("Host", ClsSignatureUtil.Host);
            Map<String,String> query = new HashMap<String, String>();
            query.put("logset_id",logsetId);
            query.put("topic_ids",topicIds);
            query.put("start_time",startTime);
            query.put("end_time",endTime);
            query.put("query_string",queryString);
            query.put("limit",limit);
            if(StringUtils.isNotBlank(context)){
                query.put("context",context);
            }
            if(StringUtils.isNotBlank(sort)){
                query.put("sort",sort);
            }
            header.put("Authorization",ClsSignatureUtil.getGetPostSignature(new HashMap<String, String>(),new HashMap<String, String>(),path,"get"));//get请求可不传入param和header
            return HttpUtil.get("http://"+ClsSignatureUtil.Host+path,query,header);
        }

六、总结

（1）、刚开始无从下手，看不懂API文档，最后还是接起来了，这说明：只要去尝试和学习，问题总会被解决的；
