Thesis contains overview of monitoring and log analysis, specifics of application log analysis and log file formats definitions. Various available systems for log analysis both proprietary and open-source are compared and categorized with overview comparison tables of supported functionality. Based on the comparison and requirements analysis appropriate solution for sample data is chosen. The ELK stack (Elasticsearch, Logstash and Kibana) and ElastAlert framework are deployed and configured for analysis of sample application log data. Logstash configuration is adjusted for collecting, parsing and processing sample data input supporting reading from file as well as online socket logs collection. Additional information for anomaly detection is computed and added to log records in Logstash processing. -
Analysis of Web Logs and Web User in Web Mining
International Journal of Network Security & Its Applications (IJNSA), Vol.3, No.1, January 2011 ANALYSIS OF WEB LOGS AND WEB USER IN WEB MINING L.K. Joshila Grace 1, V.Maheswari 2, Dhinaharan Nagamalai 3, 1Research Scholar, Department of Computer Science and Engineering [email protected] 2 Professor and Head,Department of Computer Applications 1,2 Sathyabama University,Chennai,India 3Wireilla Net Solutions PTY Ltd, Australia ABSTRACT Log files contain information about User Name, IP Address, Time Stamp, Access Request, number of Bytes Transferred, Result Status, URL that Referred and User Agent. The log files are maintained by the web servers. By analysing these log files gives a neat idea about the user. This paper gives a detailed discussion about these log files, their formats, their creation, access procedures, their uses, various algorithms used and the additional parameters that can be used in the log files which in turn gives way to an effective mining. It also provides the idea of creating an extended log file and learning the user behaviour. KEYWORDS Web Log file, Web usage mining, Web servers, Log data, Log Level directive. 1. INTRODUCTION Log files are files that list the actions that have been occurred. These log files reside in the web server. Computers that deliver the web pages are called as web servers. The Web server stores all of the files necessary to display the Web pages on the users computer. All the individual web pages combines together to form the completeness of a Web site.

PUB DATE Feb 93 NOTE 9p.; Paper presented at the Annual Meeting of the Western States Communication Association (64th, Albuquerque, NM, February 12-16, 1993). PUB TYPE Speeches/Conference Papers (150) -- Viewpoints (Opinion/Position Papers, Essays, etc.) (120) EDRS PRICE MFO1 /PCO1 Plus Postage. DESCRIPTORS Communication Research; Definitions; *Electronic Mail; Higher Education; Interpersonal Communication; Models; *Social Influences IDENTIFIERS *Communication Behavior; Computer Mediated Communication; *Flaming (Computei Mediated Communication) ABSTRACT This paper explores the phenomenon of "flaming," which has been typically cited as an antisocial effect of computer-mediated communication. The paper discusses the diverse range of conceptual and operational definitions of flaming found in the literature. The paper offers a four-point critique of previous theoretical explanations of flaming, and suggests an alternative definition of flaming, which asserts both a behavioral and interpretive dimension to flaming. Drawing from the work of J. Fulk, J. Schmitz, and C. W. Steinfield, the paper then develops a social influence model of flaming that provides.a more flexible and powerful approach than previous theories, while yielding potentially useful insights to guide future research. A figure representing the model is included. (Contains 56 references.)(RS) *********************************************************************** -

HOW COMPUTER-MEDIATED COMMUNICATION CAN CONFUSE EMOTIONS IN DIVERSE TEAMS by Adam Bartek Submitted in partial fulfillment of the requirements for Departmental Honors in the Department of Information Systems and Supply Chain Management Texas Christian University Fort Worth, Texas May 2, 2014 ii HOW COMPUTER-MEDIATED COMMUNICATION CAN CONFUSE EMOTIONS IN DIVERSE TEAMS Project Approved: Supervising Professor: Beata Jones, Ph.D. Department of Information Systems and Supply Chain Management Charles Greer, Ph.D. Department of Management, Entrepreneurship, and Leadership David Preston, Ph.D. Department of Information Systems and Supply Chain Management iii ABSTRACT This study focused on how various forms of CMC (Computer-mediated communication) were perceived and analyzed in a team setting by different genders and members of different generational groups. Specifically, the aspects of flaming, emoticons, and conflict resolution were examined in detail. Hypotheses concerning flaming were mixed as while all participants disliked flaming, baby boomer-age respondents were more tolerant of it. However, all hypotheses concerning emoticon usage were not supported. Neither gender specifically supported emoticon usage. Also, younger generations were not as supportive of emoticon usage in a team setting as expected. Finally, mixed results were found for hypotheses concerning conflict resolution. While male respondents were more comfortable with conflict over CMC, there was no significantly higher level of comfort concerning conflict and CMC for younger generations. Implications and possible avenues for future research are also discussed. iv ACKNOWLEDGEMENTS This paper would not exist without the assistance and help of numerous professors, advisors, family, and friends. In particular, the guidance of the thesis committee was greatly appreciated. -

1 I give permission for public access to my thesis and for any copying to be done at the discretion of the archives librarian and/or the College librarian. Emily Merritt 06/22/12 An Analysis of the Discourse of Internet Trolling: A Case Study of Reddit.com Student presenter: Emily Rose Merritt Project advisor: Esther Castro-Cuenca With the proliferation of social media and community discussion and forum websites, interest in understanding and explaining communication on the Internet (with an emphasis on language-based communication) is on the rise. Over time, new genres of interaction have developed that take place primarily or exclusively in online communication, and with them has developed the need to investigate the structure of these interactions, what their function is within conversations and communities, what their place is within certain Internet discourses, and over time what effects they have on communication on and offline. Thus far many of these genres have been deemed at best disruptive and at worst anti-social, but when studied from a judgment-free point of view show high levels of complexity and offer us excellent opportunities to understand how the Internet is shaping and being shaped by new kinds and contexts of communication. One of these genres of interaction that has gained significant fame on some very popular forums and discussion sites is called trolling. Trolling occurs on discussion sites or message boards when a user intentionally posts erroneous or inflammatory information with the intention of provoking a strong reaction out of other users. The objective of this study is to understand the complexities of trolling, as well as some of its functions and outcomes in anonymous online communication. -

System Log Files Kernel Ring Buffer Viewing Log Files the Log Files
System Log Files Most log files are found in /var/log Checking logs are critical to see if things are working correctly Checking logs is critical to see if things are working correctly. Take a look at all the log files on scratch ls /var/log Kernel Ring Buffer The kernel ring buffer is something like a log file for the kernel; however, unlike other log files, it’s stored in memory rather than in a disk file. You can use the dmesg command to view it. Many times it is logged to /var/log/dmesg as well. It requires sudo privileges to read the /var/log/dmesg file, but not to run the dmesg command. Viewing log files There are a number of commands to view log files. cat less head tail Anytime a new entry is added to a log file, it is appended to the end of the file. This is one of those times where tail is particularly useful. Usually when we want to look at log files we want to look at the most recent entries. When organizing our viewing command - order matters. Most of the following commands produce different results. And all are useful depending on what type of results you want. Go through the thought process and figure out what each command does. Can you figure out which three produce identical results? cat /var/log/syslog cat /var/log/syslog | grep daemon cat /var/log/syslog | grep daemon | tail -n 10 cat /var/log/syslog | tail -n 10 cat /var/log/syslog | tail -n 10 | grep daemon less /var/log/syslog less /var/log/syslog | tail -n 10 | grep daemon head -n 10 /var/log/syslog head -n 10 /var/log/syslog | grep daemon tail -n 10 /var/log/syslog tail -n 10 /var/log/syslog | grep daemon If you add the -f option to the tail command it provides a live watch of the log file. -
Netiquette (Adapted for Web Design 1) We Expect Other Drivers to Observe the Rules of the Road
Netiquette (Adapted for Web Design 1) We expect other drivers to observe the rules of the road. The same is true as we travel through cyberspace. That's where netiquette, a term allegedly coined from either network etiquette or Internet etiquette comes in handy. To guide you through your online communications, keep these pointers in mind: 1.Avoid writing e-mail or posting messages in blogs, newsgroups, forums, chat rooms and other online venues using all capital letters. IT LOOKS LIKE YOU'RE SHOUTING! Not only that, it's difficult to read. 2.When you talk with someone, the tone and inflections of your voice convey great meaning. For informal written conversations (avoid when a professional tone is required), you can add personality and humor to your messages with smileys, also known as emoticons. These are expressions you create using the characters on your keyboard. Below are some of the more popular smileys. Can you guess what they mean? Go to the end of this page to find out. 3.Keep your written communications focused. This is true whether sending e-mail or posting messages online. Few people like reading lengthy text on a computer screen. Many people now receive e-mail on mobile phones and other portable devices. Tiny screens make reading e- mail challenging. 4.To shorten messages for informal written conversations (avoid when a professional tone is required), use common abbreviations: < BTW > means By the Way. A < G > enclosed in brackets indicates grinning. < IMHO > means In My Humble Opinion. A good one to keep handy in case you're worried about offending someone is < ROTFL > measn Rolling on the Floor Laughing. -

WallStreetBets: Positions or Ban Christian J. Boylston, Beatriz E. Palacios, Plamen T. Tassev Georgia Institute of Technology WallStreetBets 2 Abstract r/wallstreetbets (WallStreetBets or WSB) is a subreddit devoted to irreverent memes and high-risk options tradings. As of March 30, 2020 the subreddit boasts a usership of nearly 1.1 million subscribers and self-describes as “if 4chan found a Bloomberg terminal.” This paper will utilize Amy Jo Kim’s community design principles along with social psychology theory as frameworks to understand how this chaotic, oftentimes offensive community has developed one of the largest and most loyal user bases on the platform. We further will argue that humor plays a vital role in promoting in-group cohesion and in providing an unconventional third place for traders (and thinly veiled gamblers) to seek support from each other in the form of vulgar, yet good-humored taunting. Keywords: high risk trading, humor, online community, third place, gambling WallStreetBets 3 WallStreetBets: Positions or Ban r/wallstreetbets (WallStreetBets or WSB) is a subreddit devoted to irreverent memes and high-risk options tradings. As of March 30, 2020 the subreddit boasts a usership of nearly 1.1 million subscribers. Members congregate here to talk shop about the market, share outlandish memes, and pepper each other with light-hearted teasing and support in equal measure. The community occupies an irreplicable space in the Reddit landscape with its instantly recognizable linguistic style, headline-catching antics, and vast reservoir of overzealous devotees.
