linux项目工程资料-Go实现的简易Linux监控系统的后端，实现的简易Linux监控系统的后端，适用于x86.zip

#### 介绍 >这是一个用Golang实现的Linux监控系统后台，适用于x86_64，目前功能还较为简单，至于前端，本人抽不出来时间写，苦涩。 > >**常规功能**：该系统实现了进程资源，系统资源实时监控的接口，类似与Linux的top命令，通过websocket推送到前端。集成了mysql与mongodb数据库，用于存储进程资源等信息，便于后期对某个进程做性能分析。 >也可以通过接口进行注册进程使用资源阈值以及处理方式，超过阈值进行处理。 > >**特色功能**：可以查看某个进程的系统调用。通过Go的syscall包，使用ptrace系统调用追踪某个进程的系统调用情况，但是该功能并不完善，比如当被跟踪进程进入系统调用不出来，这时候跟踪进程就没办法退出跟踪了（除非把自己杀死），具体解决方法思路：启动一个子进程来跟踪别的进程， >通过通道或者RPC通讯，目前在想解决步骤。 ##### 运行项目 ```sh $ cd <项目根目录> $ cd script $ sh build.sh ``` ##### 项目目录介绍 ```shell script ├── cmd #入口包 │   ├── app #初始化包 │   │   └── ligoconf.go #初始化配置信息 │   └── main.go #启动入口文件 ├── configs #配置信息包 │   ├── conf.json #全局配置文件 │   ├── logcfg.xml #日志配置文件 │   ├── logs.log #日志 │   └── 配置文件说明.md ├── front #前端静态文件包 ├── pkg #业务处理包 │   ├── api #路由包 │   │   └── router.go #路由接入文件 │   ├── conn #连接提供包 │   │   ├── dbclient.go #数据库客户端 │   │   └── dockerclient.go #docker客户端 │   ├── cons #常量包 │   │   ├── exitcode.go #退出码 │   │   └── httpcode.go #http请求标识码 │   ├── model #实体类层 │   │   ├── conf.go #配置信息实体类 │   │   ├── process.go #进程信息实体类 │   │   ├── ptrace.go #trace信息实体类 │   │   ├── reqresp.go #请求返回信息实体类 │   │   └── resource.go #主机信息实体类 │   └── service #总业务处理层 │   ├── ctl #控制器层，与router对接 │   │   ├── hostctl.go #主机信息控制器 │   │   └── processctl.go #进程控制器 │   ├── db #数据库访问层 │   │   ├── dbinterface.go #数据库访问接口 │   │   ├── mongodb.go #mongo实现 │   │   └── mysql.go #mysql实现 │   ├── dbsync #数据库同步业务层 │   │   ├── dbsvc.go #数据库同步业务文件 │   │   └── dbtimer.go #数据库同步定时器 │   ├── host #主机资源访问层 │   │   ├── cpu.go #cpu资源提供 │   │   ├── memory.go #内存资源提供 │   │   ├── process.go #进程资源提供 │   │   └── ptrace.go #系统调用资源提供 │   └── svc #具体业务处理层 │   ├── hostsvc.go #主机资源业务处理 │   └── processsvc.go #进程资源业务处理 ├── script #脚本部署层 ├── test #测试层 └── utils #工具类层 ├── errsplitutil.go #异常处理 ├── fileutil.go #文件处理 └── logutil.go #日志处理 ``` ### 主要接口 #### 进程资源推送 + URL: IP:Port/monitor/process/stream + Method: GET + Response ```json { "code":200, "message":"success", "data": [ {"pid":26356,"pPid":26354,"name":"c:/Program Files/Tencent/WeChat/WeChat.exe\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\0000\u0000\u0000\u0000","tgid":26356,"state":"S","uid":1000,"gid":1000,"threads":42,"vmPeak":3848840,"vmSize":2882272,"vmLck":64,"vmPin":0,"vmHWM":512524,"vmRss":388792,"vmData":326764,"vmStk":132,"vmExe":1904360,"vmLib":0,"vmPTE":1260,"vmSwap":0,"voluntaryCS":16609838,"noVoluntaryCS":6623,"cpuUsage":0.18170656,"cpuUsed":34011,"time":0,"ifAlarm":false,"alarmMessage":{"cpuMsg":"","vmMsg":""}}, {"pid":26361,"pPid":1,"name":"/usr/lib/i386-linux-gnu/deepin-wine/./wineserver.real\u0000-p0\u0000","tgid":26361,"state":"S","uid":1000,"gid":1000,"threads":1,"vmPeak":17860,"vmSize":8820,"vmLck":0,"vmPin":0,"vmHWM":15108,"vmRss":5564,"vmData":4360,"vmStk":132,"vmExe":484,"vmLib":3772,"vmPTE":48,"vmSwap":0,"voluntaryCS":17262641,"noVoluntaryCS":4111,"cpuUsage":0.07366482,"cpuUsed":11203,"time":0,"ifAlarm":false,"alarmMessage":{"cpuMsg":"","vmMsg":""}}, {"pid":4473,"pPid":3605,"name":"/opt/google/chrome/chrome --type=renderer --field-trial-handle=914862911565256638,18363096547406141597,131072 --lang=zh-CN --enable-crash-reporter=00eb75a2-7563-43c0-a281-cd132289c04e, --origin-trial-disabled-features=SecurePaymentConfirmation --num-raster-threads=4 --enable-main-frame-before-activation --renderer-client-id=190 --no-v8-untrusted-code-mitigations --shared-files=v8_context_snapshot_data:100","tgid":4473,"state":"S","uid":1000,"gid":1000,"threads":19,"vmPeak":42430596,"vmSize":38423504,"vmLck":0,"vmPin":0,"vmHWM":175040,"vmRss":157116,"vmData":244088,"vmStk":132,"vmExe":161068,"vmLib":9404,"vmPTE":1292,"vmSwap":5764,"voluntaryCS":1628,"noVoluntaryCS":75,"cpuUsage":0.06875384,"cpuUsed":173,"time":0,"ifAlarm":false,"alarmMessage":{"cpuMsg":"","vmMsg":""}}, ...... ] } ``` #### 进程快照获取 + URL: IP:Port/monitor/process/snapshot/{pid} + Method: GET + Response ```json { "code":200, "message":"success", "data": [ { "pid":26356, "pPid":26354, "name":"c:/Program Files/Tencent/WeChat/WeChat.ex0000", "tgid":26356, "state":"S", "uid":1000, "gid":1000, "threads":42, "vmPeak":3848840, "vmSize":2882272, "vmLck":64,"vmPin":0, "vmHWM":512524, "vmRss":385484, "vmData":326764, "vmStk":132, "vmExe":1904360, "vmLib":0, "vmPTE":1260, "vmSwap":0, "voluntaryCS":20189781, "noVoluntaryCS":12706, "cpuUsage":0.18742293, "cpuUsed":38731, "time":0, "ifAlarm":false } ] } ``` #### 强制停止进程 + URL: IP:Port/monitor/process/kill/{pid} + Method: GET + Response ```json { "code":200, "message":"success", "data":null } ``` #### 获取进程近况 + URL: IP:Port/monitor/process/status/{pid} + Method: GET + Response ```json ``` #### 注册进程资源阈值 + URL: IP:Port/monitor/process/alarm/register + Method: POST + Request ```json { "pid":4084, #进程pid "vmLimit":9999999, #进程物理内存阈值 "cpuLimit":0.01, #进程CPU使用阈值 "operate":2 #告警操作 } ``` + Response ```json ``` #### 跟踪�
