-在 `init` 函数里，需要去 load, attach eBPF程序，如有需要可能还会创建用于接收perf事件的线程。为了开发方便，coolbpf提供了简单的宏定义去完成这一系列的操作，即 `LOAD_SKEL_OBJECT(skel_name, perf);` 。因此，一般 `init` 函数具体形式如下：
+在 `init` 函数里，需要去 load, attach eBPF程序。为了开发方便，coolbpf提供了简单的宏定义去完成这一系列的操作，即 `LOAD_SKEL_OBJECT(skel_name);` 。因此，一般 `init` 函数具体形式如下：
 
 ```c

 {
-    return LOAD_SKEL_OBJECT(bpf_sample2, perf);;
+    return LOAD_SKEL_OBJECT(bpf_sample);
+}
+```
+
+对于 `call` 函数，我们需要周期性去读取 `map` 数据。本样例，在 `call` 函数读取 `count` map里面的数据，去统计事件触发的频次。
+
+
+```c
+int call(int t, struct unity_lines *lines)
+{
+    int countfd = bpf_map__fd(bpfsample->maps.count);
+    int default_key = 0;
+    uint64_t count = 0;
+    uint64_t default_count = 0;
+    struct unity_line* line;
+
+    bpf_map_lookup_elem(countfd, &default_key, &count);
+    bpf_map_update_elem(countfd, &default_key, &default_count, BPF_ANY);
+
+    unity_alloc_lines(lines, 1); 
+    line = unity_get_line(lines, 0);
+    unity_set_table(line, "bpfsample");
+    unity_set_value(line, 0, "value", count);
+
+    return 0;
 }
 ```
 
-对于 `call` 函数，我们保持不变，即直接 `return 0`。
 
 对于 `deinit` 函数，同 `init` 函数里提供的 `LOAD_SKEL_OBJECT` 宏定义一样，我们也提供了类似的销毁宏定义，即：`DESTORY_SKEL_BOJECT`。 因此，一般 `deinit` 函数具体形式如下：
 
 ```c
 int deinit(void *arg)
 {
-    return DESTORY_SKEL_BOJECT(bpf_sample2);
+    return DESTORY_SKEL_BOJECT(bpf_sample);
 }
 ```

+## 基于 eBPF 的事件监控开发手册
+
+
+我们在 `source/tools/monitor/unity/collector/plugin/bpfsample2` 路径提供了一个基于 eBPF 的监控开发样例。其主要包含三个部分：
+
+1. Makefile: 用于编译该工具；
+2. bpfsample2.bpf.c: 此处编写 eBPF 程序
+3. bpfsmaple2.c: 此处编写用户态程序
+
+接下分别介绍这三个部分。
+
+### Makfile
+
+```Makefile
+newdirs := $(shell find ./ -type d)
+
+bpfsrcs := bpfsample2.bpf.c
+csrcs := bpfsample2.c
+so := libbpfsample2.so
+
+include ../bpfso.mk
+```
+
+1. `bpfsrcs`: 用来指定需要编译的 eBPF 程序源文件
+2. `csrcs`: 用来指定需要编译的用户态程序源文件
+3. `so`: 用来指定生成目标动态库名称
+
+开发者只需要关注上述三个变量的修改即可。
+
+
+### bpfsample2.bpf.c: eBPF 程序的编写
+
+```c
+#include <vmlinux.h>
+#include <coolbpf.h>
+#include "bpfsample2.h"
+
+BPF_PERF_OUTPUT(perf, 1024);
+
+SEC("kprobe/netstat_seq_show")
+int BPF_KPROBE(netstat_seq_show, struct sock *sk, struct msghdr *msg, size_t size)
+{
+    struct event e = {};
+
+    e.ns = ns();
+    e.cpu = cpu();
+    e.pid = pid();
+    comm(e.comm);
+    
+    bpf_perf_event_output(ctx, &perf, BPF_F_CURRENT_CPU, &e, sizeof(struct event));
+    return 0;
+}
+
+```
+
+1. `vmlinux.h` 和 `coolbpf.h` 是coolbpf框架提供的两个头文件，里面包含了类似 `BPF_PERF_OUTPUT` 的helper函数，以及内核结构体的定义
+2. `bpfsample2.h` 是开发者自定义的头文件
+
+
+### bpfsample2.c: 用户态程序的编写
+
+unity 监控框架提供了三个函数，分别是：
+
+```c
+int init(void *arg)
+{
+    return 0;
+}
+
+int call(int t, struct unity_lines *lines)
+{
+    return 0;
+}
+
+void deinit(void)
+{
+}
+```
+
+在 `init` 函数里，需要去 load, attach eBPF程序，如有需要可能还会创建用于接收perf事件的线程。为了开发方便，coolbpf提供了简单的宏定义去完成这一系列的操作，即 `LOAD_SKEL_OBJECT(skel_name, perf);` 。因此，一般 `init` 函数具体形式如下：
+
+```c
+int init(void *arg)
+{
+    return LOAD_SKEL_OBJECT(bpf_sample2, perf);;
+}
+```
+
+对于 `call` 函数，我们保持不变，即直接 `return 0`。
+
+对于 `deinit` 函数，同 `init` 函数里提供的 `LOAD_SKEL_OBJECT` 宏定义一样，我们也提供了类似的销毁宏定义，即：`DESTORY_SKEL_BOJECT`。 因此，一般 `deinit` 函数具体形式如下：
+
+```c
+int deinit(void *arg)
+{
+    return DESTORY_SKEL_BOJECT(bpf_sample2);
+}
+```

+# 1、unity 监控框架概述
+
+unity 监控框架以插件化开发为主，支持coolbpf 应用，以及多种数据发布方式。具有配置灵活，资源占用率低等优点，适合在服务器监控等领域部署。
+
+![frame](image/frame.png)
+
+# 2、开发构建流程
+
+## 2.1 clone 代码
+
+开发机可以访问gitee和registry.cn-hangzhou.aliyuncs.com，并且已经安装了docker 和 git。
+
+```
+git clone -b unity https://gitee.com/anolis/sysak.git
+```
+
+## 2.2 拉起容器
+
+```
+docker run -v /root/1ext/code/:/root/code -v /:/mnt/host:ro --net=host --pid=host --name unity --privileged  -itd registry.cn-hangzhou.aliyuncs.com/sysom/sysom:v1.0 /bin/sh
+```
+
+docker 参数说明：
+
+* /root/1ext/code/:/root/code  -> 将代码目录挂载到容器目录下，方便代码同步
+* /:/mnt/host:ro/:/mnt/host:ro  ->将host根目录的以只读方式挂载进来
+* /var/run/docker.sock:/var/run/docker.sock -> 挂载host 侧的docker 接口，可以根据自己开发机的实际情况进行选择
+* --name unity  docker 名，可以自定义命名
+* --privileged 特权容器模式，如果要在容器里面进行调试，该选项不能省略
+
+启动编译
+
+```
+./configure --enable-libbpf --enable-target-unity
+ make
+```
+
+编译后在 sysak/out/.sysak_components/tools/dist 目录下会生成目标包文件。
+
+## 2.3 准备 plugin.yaml 配置文件
+
+unity 监控启动脚本默认会从 /etc/sysak/plugin.yaml 读取配置。典型的配置表说明：
+
+```
+config:
+  freq: 20   # 采集间隔
+  port: 8400  # 监听端口
+  bind_addr: 0.0.0.0 # 监听ip
+  backlog: 32  # 服务监听对队列长度，
+  identity:   # 实例id配置模式，当前支持以下五种模式
+  		    #	 hostip: 获取主机IP
+  		    #	curl: 通过网络请求获取，需要指定url 参数，适合ECS场景
+  		    #	file: 从文件读取，需要指定path 参数	
+  		    # specify:	指定id，需要指定name参数
+    mode: specify
+    name: test_specify
+  real_timestamps: true #上报监测数据的真实时间，默认关闭
+  unix_socket: "/tmp/sysom_unity.sock" #通过unix_socket方式进行数据传输，默认关闭
+  proc_path: /mnt/host/  # proc 文件路径，在host侧，为 / 在容器侧，如配置 -v /:/mnt/host 则配置为 /mnt/host
+  
+outline:   # 外部数据入口，适合接入外部数据场景
+  - /tmp/sysom    # 外部unix socket 路径，可以指定多个
+
+luaPlugins: ["proc_buddyinfo", "proc_diskstats", "proc_meminfo", "proc_mounts", "proc_netdev",
+            "proc_snmp_stat", "proc_sockstat", "proc_stat", "proc_statm", "proc_vmstat"]  # 控制lua 插件加载
+            
+
+plugins:    # 插件列表 对应 /collector/plugin 路径下编译出来的c库文件。
+  - so: kmsg   # 库名
+    description: "collect dmesg info."  # 描述符
+    ……
+
+metrics:   # export 导出的 metrics 列表
+  -
+    title: sysak_proc_cpu_total  # 显示的表名
+    from: cpu_total     # 数据源头，对应collector生成的数据表
+    head: mode   # 字段名，在prometheus 中以label 方式呈现
+    help: "cpu usage info for total."   # help 说明
+    type: "gauge"   # 数据类型
+    ……
+```
+
+## 2.4 启动监控
+
+进入 sysak/out/.sysak_components/tools/dist/app/beeQ 目录下， 执行run.sh 脚本，启动监控
+执行 curl 即可以查询到实时数据
+
+```
+curl 127.0.0.1:8400/metrics
+```
+
+# 3、监控开发
+
+## 3.1、监控指标采集 by lua
+
+本节将描述讲解如何基于lua 开发proc 数据采集。
+
+### 3.1.1、纯pystring 处理方法
+
+预备知识，lua 
+
+* [pystring](https://gitee.com/chuyansz/sysak/blob/opensource_branch/source/tools/monitor/unity/beaver/guide/pystring.md) 库，处理字符串
+* [面向对象设计](https://gitee.com/chuyansz/sysak/blob/opensource_branch/source/tools/monitor/unity/beaver/guide/oop.md)
+
+以提取 /proc/net/sockstat 数据为例，原始的信息如下：
+
+```
+#cat /proc/net/sockstat
+sockets: used 83
+TCP: inuse 6 orphan 0 tw 0 alloc 33 mem 2
+UDP: inuse 6 mem 12
+UDPLITE: inuse 0
+RAW: inuse 0
+FRAG: inuse 0 memory 0
+```
+
+#### 3.1.1.1、数据处理策略
+sockstat 接口导出的数据非常有规律，基本上是
+
+```
+[大标题]: [小标题] [值] ……
+[大标题]: [小标题] [值] ……
+```
+
+这种方法进行组合，可以针对以上方式进行处理。
+
+#### 3.1.1.2、数据格式
+
+监控使用 [protobuf](https://www.jianshu.com/p/a24c88c0526a) 来序列化和存取数据，标准数据.proto 文件描述如下：
+
+```
+	message labels {
+                required string name   = 1;
+                required string index  = 2;
+                }
+            message values {
+                required string name   = 1;
+                required double value  = 2;
+                }
+            message logs {
+                required string name   = 1;
+                required string log    = 2;
+                }
+            message  dataLine{
+                required string line = 1;
+                repeated labels  ls  = 2;
+                repeated values  vs  = 3;
+                repeated logs   log  = 4;
+                }
+            message  dataLines{
+                repeated dataLine  lines = 1;
+                }
+           }
+```
+
+想了解监控 对 protobuf的处理，可以参考 [这个通用库](https://gitee.com/chuyansz/sysak/blob/opensource_branch/source/tools/monitor/unity/common/protoData.lua) 
+
+#### 3.1.1.3、 vproc 虚基础类
+vproc 是所有 proc 接口数据采集的基础类，提供了通用的数据封装函数。根据前面的proto 文件描述，存储数据实质就是一堆数据表行组成的，在[vproc](https://gitee.com/chuyansz/sysak/blob/opensource_branch/source/tools/monitor/unity/collector/vproc.lua) 声明如下：
+
+```
+function CvProc:_packProto(head, labels, vs, log)
+    return {line = head, ls = labels, vs = vs, log = log}
+end
+```
+
+添加数据行：
+
+```
+function CvProc:appendLine(line)
+    table.insert(self._lines["lines"], line)
+end
+```
+
+将生成好的数据往外部table 中推送并清空本地数据：
+
+```
+function CvProc:push(lines)
+    for _, v in ipairs(self._lines["lines"]) do
+        table.insert(lines["lines"], v)
+    end
+    self._lines = nil
+    return lines
+end
+```
+
+#### 3.1.1.4、整体代码实现
+了解了vproc 类后，就可以从vproc 实现一个 /proc/net/sockstat 数据采集接口。代码 实现和注释如下：
+
+```
+require("class")  -- 面向对象 class 声明
+local pystring = require("common.pystring")
+local CvProc = require("collector.vproc")
+
+local CprocSockStat = class("procsockstat", CvProc)  -- 从vproc 继承
+
+function CprocSockStat:_init_(proto, pffi, pFile)   -- 调用构造函数
+    CvProc._init_(self, proto, pffi, pFile or "/proc/net/sockstat")
+end
+
+function CprocSockStat:proc(elapsed, lines)   -- 在主循环中会周期性调用proc 函数进行收集数据
+    CvProc.proc(self)   -- 新建本地表
+    local vs = {}    -- 用于暂存有效数据
+    for line in io.lines(self.pFile) do    -- 读取文件内容
+        local cells = pystring:split(line, ":", 1)   -- 按: 分割标题和内容
+        if #cells > 1 then   -- 防止 空行产生无效数据
+            local head, body = cells[1], cells[2]
+            head = string.lower(head)  -- 标题统一小写
+            body = pystring:lstrip(body, " ")   -- 去除开头的空格
+            local bodies = pystring:split(body, " ")   -- 按空格分割内容
+            local len = #bodies / 2
+            for i = 1, len do
+                local title = string.format("%s_%s", head, bodies[2 * i - 1])    -- 组合数值标题
+                local v = {
+                    name=title,  
+                    value=tonumber(bodies[2 * i])
+                }
+                table.insert(vs, v)  -- 添加到暂存表中
+            end
+        end
+    end
+    self:appendLine(self:_packProto("sock_stat", nil, vs))  -- 保存到本地表中
+    return self:push(lines)   --推送到全局表，并发送出去
+end
+
+return CprocSockStat   -- 这一行不能少
+```
+
+#### 3.1.1.5、注册到主循环中
+
+[loop.lua](https://gitee.com/chuyansz/sysak/blob/opensource_branch/source/tools/monitor/unity/collector/loop.lua) 是周期性采样所有数据的循环实现。首先将文件引入：
+
+```
+local CprocSockStat = require("collector.proc_sockstat")
+```
+
+然后添加到collector 表中
+
+```
+CprocSockStat.new(self._proto, procffi),
+```
+
+此时数据已经保存在本地
+
+#### 3.1.1.6、导出到export
+
+要将采集到的指标采集到export，只需要在 [plugin.yaml](https://gitee.com/chuyansz/sysak/blob/opensource_branch/source/tools/monitor/unity/collector/plugin.yaml) 中添加以下行做配置即可：
+
+```
+  - title: sysak_sock_stat
+    from: sock_stat   # 代码中声明的表行
+    head: value
+    help: "sock stat counters from /proc/net/sockstat"
+    type: "gauge"
+```
+
+#### 3.1.1.7、 数据呈现
+用浏览器打开本地8400端口，到指标链接中，就可以提取到以下新增数据
+
+```
+# HELP sysak_sock_stat sock stat counters.
+# TYPE sysak_sock_stat gauge
+sysak_sock_stat{value="frag_inuse",instance="12345abdc"} 0.0
+sysak_sock_stat{value="udplite_inuse",instance="12345abdc"} 0.0
+sysak_sock_stat{value="udp_mem",instance="12345abdc"} 8.0
+sysak_sock_stat{value="tcp_mem",instance="12345abdc"} 1.0
+sysak_sock_stat{value="tcp_alloc",instance="12345abdc"} 32.0
+sysak_sock_stat{value="frag_memory",instance="12345abdc"} 0.0
+sysak_sock_stat{value="sockets_used",instance="12345abdc"} 80.0
+sysak_sock_stat{value="raw_inuse",instance="12345abdc"} 0.0
+sysak_sock_stat{value="tcp_tw",instance="12345abdc"} 0.0
+sysak_sock_stat{value="tcp_orphan",instance="12345abdc"} 0.0
+sysak_sock_stat{value="tcp_inuse",instance="12345abdc"} 5.0
+```
+
+### 3.1.2、FFI 处理方式
+关于lua ffi 说明，可以先参考[lua扩展ffi](https://luajit.org/ext_ffi.html)，本质是lua 可以通过ffi 接口直接调用C库参数，无需经过中间栈上传参等操作。
+
+ffi的注意点：
+
+* ffi 数组下标是从0开始，和lua下标从1开始不一样；
+* 可以直接引用ffi 中的数据结构，效率要比原生lua 高很多；
+* ffi 是luajit 的功能，原生lua 并不支持；
+
+#### 3.1.2.1、 为什么要使用ffi？
+pystring 虽然可以高效处理字符串数据，但是相比c语言中的scanf 接口来说效率还是要低很多。因此按行读取proc 数据，可以采用 ffi 接口来显著提升数据处理效率
+
+#### 3.1.2.2、 ffi 数据结构和api 说明
+
+proc 数据以变参为主，下面的结构体主要用于scanf 获取变参， 用于上层数据处理
+
+```
+#define VAR_INDEX_MAX 64
+
+// 变参整数类型，用于收集纯整数类型的数据
+typedef struct var_long {
+    int no;    // 收集到参数数量
+    long long value[VAR_INDEX_MAX];   //参数列表
+}var_long_t;
+
+// 变参字符串类型
+typedef struct var_string {
+    int no; // 收集到参数数量
+    char s[VAR_INDEX_MAX][32];   //参数列表
+}var_string_t;
+
+// 变参 k vs 类型
+typedef struct var_kvs {  
+    int no;  // 收集到参数数量
+    char s[32];   // 标题
+    long long value[VAR_INDEX_MAX];   // 参数列表
+}var_kvs_t;
+```
+
+导出的c api
+
+```
+int var_input_long(const char * line, struct var_long *p);
+int var_input_string(const char * line, struct var_string *p);
+int var_input_kvs(const char * line, struct var_kvs *p);
+```
+
+综合来说：
+
+* var\_long\_t 适合纯整数数字输出的场景
+* var\_string\_t 适合纯字符串输出的场景
+* var\_kvs\_t 适合单字符串 + 多整形数字 组合的场景，如 /proc/stat的内容输出
+
+其它重复组合场景可以先按照 var\_string\_t 来收集，然后对指定位置的数字字符串通过tonumber 进行转换。
+
+#### 3.1.2.3 实际应用例子
+以[kvProc.lua](https://gitee.com/chuyansz/sysak/blob/opensource_branch/source/tools/monitor/unity/collector/kvProc.lua) 为例，它实现了一个通用kv组合的proc接口数据的数据高效的处理方法。如经常使用到的 /proc/meminfo ，是典型的kv值例子
+
+```
+#cat /proc/meminfo
+MemTotal:        2008012 kB
+MemFree:          104004 kB
+MemAvailable:    1060412 kB
+Buffers:          167316 kB
+Cached:           877672 kB
+SwapCached:            0 kB
+Active:          1217032 kB
+Inactive:         522236 kB
+Active(anon):     694948 kB
+Inactive(anon):      236 kB
+Active(file):     522084 kB
+Inactive(file):   522000 kB
+……
+```
+对应处理代码说明，重点需要关注**readKV**函数实现。
+
+```
+local system = require("common.system")
+require("common.class")
+local CvProc = require("collecotor.vproc")
+
+local CkvProc = class("kvProc", CvProc)
+
+function CkvProc:_init_(proto, pffi, mnt, pFile, tName)
+    CvProc._init_(self, proto, pffi, pFile)   -- 从基础类继承
+    self._protoTable = {
+        line = tName,    -- 表名 如/proc/meminfo 可以取 meminfo 为表名
+        ls = nil,
+        vs = {}
+    }

+
+## 3.2、C 插件开发
+
+在collector/plugin/sample 目录下有一个示例工程，它的本质其实就是一个so文件的编译项目。首先要看下sample 同级目录下的公共头文件 plugin_head.h，该头文件提供了数据生成的API，降低开发者实现难度。
+
+```
+/// \brief 申请数据行数量，在填入数据前统一申请，根据实际情况填入
+	/// \param lines 数据结构体
+	/// \param num 申请行号数量
+	/// \return 成功返回 0
+	inline int unity_alloc_lines(struct unity_lines * lines, unsigned int num) __attribute__((always_inline));
+	/// \brief 获取对应行数据，用于填入数据
+	/// \param lines 数据结构体
+	/// \param i 对应行下标
+	/// \return 返回对应的数据行

+	/// \brief 设置数据行 表名
+	/// \param line 行指针

+	/// \brief 设置数据行 日志信息
+	/// \return 返回mount 目录
+	char* get_unity_proc(void);
+```
+
+**数据规格限制**
+
+1. unity\_set\_table 中 table 参数长度应该小于32（不含）
+2. unity\_set\_index 中 name、index和unity\_set\_value 中 name 参数长度应该要小于16（不含）
+3. unity\_set\_index 下标从0开始，并小于 4，即最多4个索引。而且下标数值应该连续，否则数据会从留白处截断
+4.  unity\_set\_index 下标从0开始，并小于 32，即最多32个数值。而且下标数值应该连续，否则数据会从留白处截断；
+5.  unity\_set\_log 中的log 指针需要开发者进行释放；
+6. get\_unity\_proc参考2.3节中 proc_path 中的内容；
+
+### 3.2.1、sample 用例代码
+
+适合周期性数据采集的场景，通过周期性调用call 函数来收集数据
+
+参考 sample.c
+
+```
+
+	/// \brief 插件构造函数，在加载so的时候，会调用一次init
+	/// \param arg 当前未使用，为NULL
+	/// \return 成功返回 0
+	int init(void * arg) {
+	    printf("sample plugin install.\n");
+	    return 0;
+	}
+	
+	/// \brief 插件调用函数，通过调用在函数来收集要采集的指标
+	/// \param t，间隔周期，如15s的采样周期，则该值为15
+	/// \param lines 数值指针，用于填充采集到的数据。
+	/// \return 成功返回 0
+	int call(int t, struct unity_lines* lines) {
+	    static double value = 0.0;
+	    struct unity_line* line;
+	
+	    unity_alloc_lines(lines, 2);
+	    line = unity_get_line(lines, 0);
+	    unity_set_table(line, "sample_tbl1");
+	    unity_set_index(line, 0, "mode", "sample1");
+	    unity_set_value(line, 0, "value1", 1.0 + value);
+	    unity_set_value(line, 1, "value2", 2.0 + value);
+	
+	    line = unity_get_line(lines, 1);
+	    unity_set_table(line, "sample_tbl2");
+	    unity_set_value(line, 0, "value1", 3.0 + value);
+	    unity_set_value(line, 1, "value2", 4.0 + value);
+	    unity_set_value(line, 2, "value3", 3.1 + value);
+	    unity_set_value(line, 3, "value4", 4.1 + value);
+	
+	    value += 0.1;
+	    return 0;
+	}
+	
+	/// \brief 插件析构函数，调用完该函数时，必须要确保该插件已申请的资源已经全部释放完毕。
+	/// \return 成功返回 0
+	void deinit(void) {
+	    printf("sample plugin uninstall\n");
+	}
+```
+
+### 3.2.3、threads 代码
+
+sample 适合常规数据采集，周期性遍历插件拉取指标的场景。但在实际实践中，还存在数据主动推送的场景。如下图紫线路径所示：
+
+![dataflow](image/queue.png)
+
+这种场景下，可以通过创建thread 方式进行进行数据推送，相关参考代码在 collector/plugin/thread 目录
+
+```
+#include "sample_threads.h"
+#include <unistd.h>
+#include <signal.h>
+
+static volatile pthread_t sample_thread_id = 0;   //进程id，停止的时候使用
+
+static int sample_thread_func(struct beeQ* q, void * arg);  //线程回调函数声明，可以通过arg 向 线程回调函数传参
+int init(void * arg) {
+    struct beeQ* q = (struct beeQ *)arg;
+    sample_thread_id = beeQ_send_thread(q, NULL, sample_thread_func);      // 创建线程
+    printf("start sample_thread_id: %lu\n", sample_thread_id);
+    return 0;
+}
+
+static int sample_thread_func(struct beeQ* q, void * arg) {
+    unsigned int ret;
+    while (plugin_is_working()) {
+        static double value = 1.0;
+        struct unity_line* line;
+        struct unity_lines * lines = unity_new_lines();
+
+        unity_alloc_lines(lines, 1);
+        line = unity_get_line(lines, 0);
+        unity_set_table(line, "sample_tbl3");
+        unity_set_value(line, 0, "value1", 1.0 + value);
+        unity_set_value(line, 1, "value2", 2.0 + value);
+        unity_set_log(line, "log", "hello world.");
+        beeQ_send(q, lines);   // 往队列里面推送数据
+        ret = sleep(5);
+        if (ret > 0) {  // interrupt by signal
+            break;
+        }
+    }
+    return 0;
+}
+
+int call(int t, struct unity_lines* lines) {
+    static double value = 0.0;
+    struct unity_line* line;
+
+    unity_alloc_lines(lines, 1);
+    line = unity_get_line(lines, 0);
+    unity_set_table(line, "sample_tbl1");
+    unity_set_index(line, 0, "mode", "threads");
+    unity_set_value(line, 0, "value1", 1.0 + value);
+    unity_set_value(line, 1, "value2", 2.0 + value);
+
+    value += 0.1;
+    return 0;
+}
+
+void deinit(void) {
+    plugin_thread_stop(sample_thread_id);
+    printf("thread plugin uninstall\n");
+}
+
+```
+
+**在线程回调函数中，必须要判断所有调用到的函数是否被信号打断，用于决定是否需要退出并释放相应资源。**
+
+如实例代码中需要获取sleep 函数的返回值，根据[sleep函数](https://man7.org/linux/man-pages/man3/sleep.3.html)的返回值说明：
+
+```
+Zero if the requested time has elapsed, or the number of seconds
+ left to sleep, if the call was interrupted by a signal handler.
+```
+
+需要判断是否存在sleep 函数被打断的场景。
+
+## 3.3、coolbpf 插件开发
+
+关于coolbpf，可以参考[这里](https://gitee.com/anolis/coolbpf)
+
+`/collector/plugin/bpfsample2` 路径提供了一个基于 eBPF 的监控开发样例。其主要包含三个部分：
+
+1. Makefile: 用于编译该工具；
+2. bpfsample2.bpf.c: 此处编写 eBPF 程序
+3. bpfsmaple2.c: 此处编写用户态程序
+
+接下分别介绍这三个部分。
+
+### 3.3.1、Makfile
+
+```Makefile
+newdirs := $(shell find ./ -type d)
+
+bpfsrcs := bpfsample2.bpf.c
+csrcs := bpfsample2.c
+so := libbpfsample2.so
+
+include ../bpfso.mk
+```
+
+1. `bpfsrcs`: 用来指定需要编译的 eBPF 程序源文件
+2. `csrcs`: 用来指定需要编译的用户态程序源文件
+3. `so`: 用来指定生成目标动态库名称
+
+开发者只需要关注上述三个变量的修改即可。
+
+
+### 3.3.2、bpfsample2.bpf.c: eBPF 程序的编写
+
+```c
+#include <vmlinux.h>
+#include <coolbpf.h>
+#include "bpfsample2.h"
+
+BPF_PERF_OUTPUT(perf, 1024);
+
+SEC("kprobe/netstat_seq_show")
+int BPF_KPROBE(netstat_seq_show, struct sock *sk, struct msghdr *msg, size_t size)
+{
+    struct event e = {};
+
+    e.ns = ns();
+    e.cpu = cpu();
+    e.pid = pid();
+    comm(e.comm);
+    
+    bpf_perf_event_output(ctx, &perf, BPF_F_CURRENT_CPU, &e, sizeof(struct event));
+    return 0;
+}
+
+```
+
+1. `vmlinux.h` 和 `coolbpf.h` 是coolbpf框架提供的两个头文件，里面包含了类似 `BPF_PERF_OUTPUT` 的helper函数，以及内核结构体的定义
+2. `bpfsample2.h` 是开发者自定义的头文件
+
+
+### 3.3.3、bpfsample2.c: 用户态程序的编写
+
+unity 监控框架提供了三个函数，分别是：
+
+```c
+int init(void *arg)
+{
+    return 0;
+}
+
+int call(int t, struct unity_lines *lines)
+{
+    return 0;
+}
+
+void deinit(void)
+{
+}
+```
+
+在 `init` 函数里，需要去 load, attach eBPF程序，如有需要可能还会创建用于接收perf事件的线程。为了开发方便，coolbpf提供了简单的宏定义去完成这一系列的操作，即 `LOAD_SKEL_OBJECT(skel_name, perf);` 。因此，一般 `init` 函数具体形式如下：
+
+```c
+int init(void *arg)
+{
+    return LOAD_SKEL_OBJECT(bpf_sample2, perf);;
+}
+```
+
+对于 `call` 函数，我们保持不变，即直接 `return 0`。
+
+对于 `deinit` 函数，同 `init` 函数里提供的 `LOAD_SKEL_OBJECT` 宏定义一样，我们也提供了类似的销毁宏定义，即：`DESTORY_SKEL_BOJECT`。 因此，一般 `deinit` 函数具体形式如下：
+
+```c
+int deinit(void *arg)
+{
+    return DESTORY_SKEL_BOJECT(bpf_sample2);
+}
+```
