在进行软件开发过程中，特别是在处理开源项目时，经常会遇到需要编译源代码以构建软件的情况。electron是一个广泛使用的开源框架，它允许开发者使用Web技术（如JavaScript、HTML和CSS）来构建跨平台的桌面应用程序。当开发者着手编译electron框架的最新版本，即22.3.27版本时，会发现一个工具是必不可少的，那就是traffic-annotation-auditor。尽管在编译过程中可能会涉及大量复杂的步骤和技术细节，但在此我们主要关注traffic-annotation-auditor这个工具的用途及其在electron编译中的重要性。 traffic-annotation-auditor是一个用于检查和审计网络流量注释的工具，它确保程序中网络通信的元数据正确且符合特定的要求。在软件开发中，对网络流量进行注释是一种良好的实践，它能够帮助开发者理解和追踪程序中的网络操作，特别是在进行安全性审计和代码审查时尤为重要。通过确保所有网络操作都有明确的注释，开发者可以更容易地验证代码是否遵循了既定的安全策略和最佳实践。 在编译electron 22.3.27版本时，traffic-annotation-auditor的主要职责是检查electron源代码中定义的网络流量注释。这一步骤通常发生在编译的预处理阶段，工具会自动扫描代码，识别网络调用，并确认是否有相应的注释与之对应。如果有遗漏或错误的注释，编译过程可能会失败，或者在没有明确警告的情况下继续，这可能会导致后期开发和维护过程中的问题。因此，确保在编译electron源代码之前，所有相关的网络注释都是完整和准确的，对于提高软件质量和安全是至关重要的。 值得注意的是，traffic-annotation-auditor在编译electron源码时并非一个可视化的交互式工具，而是一个命令行工具，它需要在编译命令行中被正确地引用和运行。它的执行通常涉及多种编译参数和配置选项，这些都需要开发者仔细阅读相关的开发文档和指南，以确保正确设置。 此外，开发者在使用traffic-annotation-auditor时，还需要关注它的更新和维护情况。随着软件开发实践的不断演进，网络注释的要求可能会发生变化，因此，开发者需要确保使用的traffic-annotation-auditor版本与编译的electron版本兼容，并且包含最新的安全和功能改进。 在软件开发的整个生命周期中，从构建到部署和维护，遵循良好的网络注释实践都是至关重要的。electron框架的开发者通过内置对traffic-annotation-auditor的需求，强调了这一实践的重要性。虽然这为初学者和新接触electron框架的开发者带来了一定的学习曲线，但长远来看，通过确保网络安全和提高代码的可读性，这样的实践可以极大地提高软件产品的质量和可信度。 对于那些希望深入了解electron框架，尤其是希望参与其开发或贡献代码的开发者而言，熟悉traffic-annotation-auditor以及如何在编译过程中使用它是一项基础且必要的技能。这一过程不仅涉及技术知识的掌握，也体现了开源社区对于代码质量和安全性的高度关注。随着开发者在实践中不断运用这一工具，他们将能更好地理解网络注释在维护项目安全和清晰性方面的作用，最终成为能够为开源社区作出贡献的负责任的成员。

STG (SNMP Traffic Grapher) version 1.4.5 Copyright (C) 2000 Leonid Mikhailov This freeware utility allows monitoring of supporting SNMPv1 and SNMPv2c devices including Cisco, Livingstone, Riverstone etc. Intended as fast aid for network administrators who need prompt access to current information about state of network equipment. Copyright In brief: You may use STG for any commercial and non commercial purpose. You may distribute STG for free. You may charge a fee for the physical act of transferring a copy only. This program is distributed WITHOUT ANY WARRANTY. Use it at your own risk. I cannot guarantee accuracy of displayed data. I am not liable to you for any possible damages etc... Source code is not available. Features: Single graph displays changes of two configurable SNMP variables with display of Current, Average, Maximum values. Screen snapshot: http://www.chat.ru/~leonidvm/stg.jpg Could be downloaded from: http://www.chat.ru/~leonidvm/ ftp://ftp.naytov.com/pub/stg/ Newer versions will be there too. STG was written as an add-on for MRTG application by Tobias Oetiker. MRTG (http://ee-staff.ethz.ch/~oetiker/webtools/mrtg/mrtg.html) is absolutely necessary for every network and system administrator. It provides SNMP monitoring of any number devices simultaneously. However during my duties I often have to check state of ports on different routers that are not always in my domain and setting MRTG configuration takes some time. And does not allow to see last second changes in traffic. That's why STG was written. It allows monitoring of SNMP devices with different update periods starting from 0.01s so you could see what's happening right now. Also STG could be useful during network problems troubleshooting. It runs on MS Windows 2000, Windows NT 4.0, Windows 98 and Windows Millenium. To run it on WinNT 4.0 you may need mgmtapi.dll and mib.bin (see below) To run it on Win98 and Millenium you will need mgmtapi.dll, mib.bin and wsnmp32.dll (see below) Written with Microsoft Visual C++ 6.0. Uses Microsoft SNMP API. Features: Single graph displays changes of two configurable SNMP variables with display of Current, Average, Maximum values. Changes in version 1.4.5: Bugs fixed: 1. Corrected bug that prevented version 1.4.4 from running on NT4 Changes in version 1.4.4: Bugs fixed: 1. Fixed bug with log file where sysUpTime was shown as nonzero for timeouted requests Changes in version 1.4.3: Bugs fixed: 1. Fixed bug with average value displayed incorrectly. - Thanks to Jim Jones, Jr.! 2. Fixed bug when red Upper Rate line has incorrect position for high Max Rate numbers. Changes in version 1.4.2: Now runs on Win 98 and Millenium. Bugs fixed: 1. Corrected startup crash (when started with configuration filename) - Thanks to Paw Larsen! Changes in version 1.4.1: 1. Both snmp OID's are requested in one network packet. 2. Actual time between two requests is calculated from target device sysUpTime (1.3.6.1.2.1.1.3.0). This should improve displayed data accuracy. - Thanks to Mike MacFaden from Riverstone Networks! 3. Log format changed: request_time,target_uptime_centisec,traffic,traffic1 request_time - local system time (human readable string) target_uptime - target sysUpTime (hundredth of seconds) traffic traffic1 e.g.: 2001-Feb-12 15:07:28.89,24244074,5078,21215 Features added: 1. Window size and status/title bar state are being saved/restored. Changes in version 1.4.0: Bugs fixed: 1. One memory leak fixed. Features added: 1. Resizeable window. Changes in version 1.3.2: Bugs fixed: 1. Corrected bug with zero replies not included in Avg value. Thanks to Rafael Prado Rocchi! Changes in version 1.3.1: Features added: 1. Option for displaying traffic in bits/bytes 2. Target Information window. Changes in version 1.2.2: Bugs fixed: 1. Corrected bug with time incorrectly shown when daylight saving option was on. Thanks to Anders Gustafsson from Sweden! 2. Changed the way of rate calculation. Now rate is calculated on basis of time that actually passed since previous sample. Before the value of "Update Period" option was used. Features added: 1. Status bar indicator of last sample time. 2. Logging ability. If option "Write Data to Log File" is checked, then program writes collected data to specified file. Log file is comma separated. Here is format: First line is the header line : Program name: File creation time,Target Address,Community string,OID,OID1 e.g.: STG Traffic Log File Created On:Sat Jun 03 14:18:36 2000,Target Address:195.239.193.125,Community:public,OID:1.3.6.1.2.1.2.2.1.10.1,OID1:1.3.6.1.2.1.2.2.1.16.1 Second line lists values names. From third line starts actual program data. 3. Log file is rotated every N hours, days, weeks or months. Rotation happens at the end of hour, day, week or month respectively. Configuration Options: Graph: SNMP values: Target Address: e.g myrouter1.mydomain.com Community: e.g public Two SNMP Object IDs (SNMP ID of the parameter you want to see): OID e.g 1.3.6.1.2.1.2.2.1.10.1 OID1 e.g 1.3.6.1.2.1.2.2.1.16.1 Every or any of them could be gauge value - some SNMP parameters should be treated as absolute ("as is") (e.g CPU load or temperature) In case you need only one walue - enter the same string into both OID and OID1 fields. If you need more than two - try to use more than one instance of program. Network values: Request Timeout (milliseconds): minimal 10ms (0.01 sec) maximal 32000ms (32s) probably shouldn't be more than 5000 (5 seconds) but that's vary Update Period (milliseconds): minimal 100ms (0.1 sec) maximal 2000000000ms (Too long to wait...) To get valid graph this value should be set higher than network timeout. Max Rate - byte/second: minimal 1 maximal 2000000000 This option determines position of horisontal red line. Note, it is in bytes in second, so if you want to monitor 1Mbit line it should be set a little higher than 131072 Reverse option - changes direction of graph. Show traffic in Bytes / Bits - show traffic values in bits or bytes Fix Rate - Show graph data only up to "Max Rate" and don't allow automatic scaling. Log File: Write Data - enables/disables logging. To Log File - specifies file for logging. Rotate N Log Files - specifies number of log files to rotate - minimum 1. Rotated files will have numeric extention added: *.000 *.001 etc. Every N Hour(s) or Day(s) or Week(s) or Month(s) - rotate log period. Rotation happens at the end of hour, day, week or month respectively. Log file format: request_time,target_uptime_centisec,traffic,traffic1 request_time - local system time (human readable string), target_uptime - target sysUpTime (hundredth of seconds), traffic - traffic1 - e.g.: 2001-Feb-12 15:07:28.89,24244074,5078,21215 Settings could be saved and recalled through Save and Open menus. Program uses ".stg" extention for settings files.

Download stg.zip (128k) http://www.chat.ru/~leonidvm/1.4.5/stg.zip ftp://ftp.naytov.com/pub/stg/1.4.5/stg.zip 2. Extract stg.exe with pkunzip or winzip into any directory (e.g. "\Program Files\STG") Winnt 4.0: 1. Download stg.zip 2. Get mgmtapi.dll and mib.bin if they are not already in \WINNT\system32\ directory. You could find them in your WinNT installation CD-ROM in i386 directory Or download nt4files.zip (11.5k) from http://www.chat.ru/~leonidvm/nt4files.zip or ftp://ftp.naytov.com/pub/stg/winnt4.0/nt4files.zip 3. Extract all files from stg.zip with pkunzip or winzip into installation directory (e.g. "\Program Files\STG") 4. Extract mgmtapi.dll and mib.bin from nt4files.zip into the same directory as stg.exe (or into \WINNT\system32\). Winnt 98 and Millenium: 1. Download stg.zip 2. Get mgmtapi.dll, mib.bin and wsnmp32.dll - download w9xlibs.zip (39k) from http://www.chat.ru/~leonidvm/w9xlibs.zip or ftp://ftp.naytov.com/pub/stg/w9x/w9xlibs.zip 3. Extract all files from stg.zip with pkunzip or winzip into installation directory (e.g. "\Program Files\STG") 4. Extract mgmtapi.dl, mib.bin and wsnmp32.dll from w9xlibs.zip into the same directory as stg.exe (or into \windows\). Deinstallation: 1. Remove all files from STG directory. 2. Remove STG directory. Running STG Prerequisites: 1. Valid DNS name or IP address of device you want to monitor. 2. Valid SNMP OID (for some values see mibs.txt file) 3. Correct SNMP community (might be "public", but not necessary). 4. SNMP should be configured on target device. 5. Your computer must have access to SNMP facility (be in access list or something like that - ask sysadmin). Configuration: 1. Open menu View\Settings 2. Set DNS name or ip address of monitoring device into Target Adress edit box. 3. Set correct community string into Community edit box. 4. Set OID of the first object in OID edit box. 5. Set OID of second object in OID1 edit box. 6. Set Update Period to desired value in milliseconds. 7. Set Max Rate to desired Value (This parameters is in bytes!). 8. Press OK. Monitoring starts automatically. Problems and Troubleshooting: If program cannot resolve Target Address or process OIDs, it reports error and stops processing. To resume it you may correct mistakes and it will retry automatically. Or you may use menu command Start to restart monitoring. Errors in OID: If you are sure that OID string is correct - than you need to check that mib.bin is in the STG directory or in \WINNT\system32\ if you run WinNT4.0 or \windows\ if you run Win98 or Millenium. Entry Point Not Found: This error arises in Win2000 when mgmtapi.dll from WinNT4.0 is somewhere in your path. Find mgmtapi.dll and delete it. Vertical Red Line: Vertical red line on graph means that there were no valid data received from target address within Request Timeout period. There may be different reasons for that: 1. Network Timeout - try to increase Request Timeout value (there is no reason for setting it higher 10000ms - it would not help) This implemetation uses SNMP protocol with no retries (could be changed in future). And SNMP uses UDP protocol with no deluvery guaranties. So this could happen. 2. Overloaded network connection between monitoring computer and target. 3. Mistyped Target Address or OIDs. If you get olny solid red than checking them might be useful. Share violation occured while accessing .... This message appears when two or more instances of stg try to write into the same log file. Make log file name unique for every instance. If you have found a bug or have suggestions - send me a message to leonidvm@mail.com I will try to correct a problem. But no guarantees. Hope this utility will be useful for you.
