Log Analysis
In computer log management and intelligence, log analysis (or ''system and network log analysis'') is an art and science seeking to make sense of computer-generated records (also called log or audit trail records). The process of creating such records is called data logging. Typical reasons why people perform log analysis are: * Compliance with security policies * Compliance with audit or regulation * System troubleshooting * Forensics (during investigations or in response to a subpoena) * Security incident response * Understanding online user behavior Logs are emitted by network devices, operating systems, applications and all manner of intelligent or programmable devices. A stream of messages in time sequence often comprises a log. Logs may be directed to files and stored on disk or directed as a network stream to a log collector. Log messages must usually be interpreted concerning the internal state of its source (e.g., application) and announce security-relevant or operations- ...

Log Management And Intelligence
Log management is the process for generating, transmitting, storing, accessing, and disposing of log data. A log data (or ''logs'') is composed of entries (records), and each entry contains information related to a specific event that occur within an organization's computing assets, including physical and virtual platforms, networks, services, and cloud environments. The process of log management generally breaks down into: * Log collection - a process of capturing actual data from log files, application standard output stream (stdout), network socket and other sources. * Logs aggregation (centralization) - a process of putting all the log data together in a single place for the sake of further analysis or/and retention. * Log storage and retention - a process of handling large volumes of log data according to corporate or regulatory policies (compliance). * Log analysis - a process that helps operations and security team to handle system performance issues and security incidents ...

Application Performance Management
In the fields of information technology and systems management, application performance management (APM) is the monitoring and management of the performance and availability of software applications. APM strives to detect and diagnose complex application performance problems to maintain an expected level of service. APM is "the translation of IT metrics into business meaning ( .e.value)." Measuring application performance Two sets of performance metrics are closely monitored. The first set of performance metrics defines the performance experienced by end-users of the application. One example of performance is average response times under peak load. The components of the set include load and response times: :* The load is the volume of transactions processed by the application, e.g., transactions per second, requests per second, pages per second. Without being loaded by computer-based demands (e.g. searches, calculations, transmissions), most applications are fast enough, whic ...

Web Log Analysis Software
Web log analysis software (also called a web log analyzer) is a kind of web analytics software that parses a server log file from a web server, and based on the values contained in the log file, derives indicators about when, how, and by whom a web server is visited. Reports are usually generated immediately, but data extracted from the log files can alternatively be stored in a database, allowing various reports to be generated on demand. Features supported by log analysis packages may include "hit filters", which use pattern matching to examine selected log data. Common indicators * Number of visits and number of unique visitors * Visit duration and last visits * Authenticated users, and last authenticated visits * Days of week and rush hours * Domains/countries of host's visitors. * Hosts list * Number of page views * Most viewed, entry, and exit pages * File types * OS used * Browsers used * Robots used * HTTP referrer * Search engines, key phrases and keywords used to fin ...

System Monitor
A system monitor is a hardware or software component used to monitor system resources and performance in a computer system. Among the management issues regarding use of system monitoring tools are resource usage and privacy. Monitoring can track both input and output values and events of systems. Overview Software monitors occur more commonly, sometimes as a part of a widget engine. These monitoring systems are often used to keep track of system resources, such as CPU usage and frequency, or the amount of free RAM. They are also used to display items such as free space on one or more hard drives, the temperature of the CPU and other important components, and networking information including the system IP address and current rates of upload and download. Other possible displays may include the date and time, system uptime, computer name, username, hard drive S.M.A.R.T. data, fan speeds, and the voltages being provided by the power supply. Less common are hardware-based sys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Server Log
In computing, logging is the act of keeping a log of events that occur in a computer system, such as problems, errors or broad information on current operations. These events may occur in the operating system or in other software. A message or ''log entry'' is recorded for each such event. These log messages can then be used to monitor and understand the operation of the system, to debug problems, or during an audit. Logging is particularly important in multi-user software, to have a central overview of the operation of the system. In the simplest case, messages are written to a file, called a ''log file''. Alternatively, the messages may be written to a dedicated logging system or to a log management software, where it is stored in a database or on a different computer system. Specifically, a ''transaction log'' is a log of the communications between a system and the users of that system, or a data collection method that automatically captures the type, content, or time of ...

Log Monitor
Log monitors are a type of software that monitor log files. Servers, application, network and security devices generate log files. Errors, problems, and more information is constantly logged and saved for later log analysis. In order to detect problems automatically, system administrators and operations set up monitors on the generated logs. The log monitors scan the log files and search for known text patterns and rules that indicate important events. Once an event is detected, the monitoring system will send an alert, either to a person or to another software Software consists of computer programs that instruct the Execution (computing), execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital comput .../ hardware system.

Data Logger
A data logger (also datalogger or data recorder) is an electronic device that records data over time or about location either with a built-in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer), and called digital data loggers (DDL). They generally are small, battery-powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Some data loggers interface with a personal computer and use software to activate the data logger and view and analyze the collected data, while others have a local interface device (keypad, LCD) and can be used as a stand-alone device. Data loggers vary from general-purpose devices for various measurement applications to very specific devices for measuring in one environment or application type only. While it is common for general-purpose types to be programmable, many remain static machines with only a limited number o ...

Audit Trail
An audit trail (also called audit log) is a security-relevant chronological record, set of records, and/or destination and source of records that provide documentary evidence of the sequence of activities that have affected at any time a specific operation, procedure, event, or device. Audit records typically result from activities such as financial transactions, scientific research and health care data transactions, or communications by individual people, systems, accounts, or other entities. The process that creates an audit trail is typically required to always run in a privileged mode, so it can access and supervise all actions from all users; a normal user should not be allowed to stop/change it. Furthermore, for the same reason, the trail file or database table with a trail should not be accessible to normal users. Another way of handling this issue is through the use of a role-based security model in the software. The software can operate with the closed-looped controls, ...

Exception Handling
In computing and computer programming, exception handling is the process of responding to the occurrence of ''exceptions'' – anomalous or exceptional conditions requiring special processing – during the execution of a program. In general, an exception breaks the normal flow of execution and executes a pre-registered ''exception handler''; the details of how this is done depend on whether it is a hardware or software exception and how the software exception is implemented. Exceptions are defined by different layers of a computer system, and the typical layers are CPU-defined interrupts, operating system (OS)-defined signals, programming language-defined exceptions. Each layer requires different ways of exception handling although they may be interrelated, e.g. a CPU interrupt could be turned into an OS signal. Some exceptions, especially hardware ones, may be handled so gracefully that execution can resume where it was interrupted. Definition The definition of an excep ...

Machine Learning
Machine learning (ML) is a field of study in artificial intelligence concerned with the development and study of Computational statistics, statistical algorithms that can learn from data and generalise to unseen data, and thus perform Task (computing), tasks without explicit Machine code, instructions. Within a subdiscipline in machine learning, advances in the field of deep learning have allowed Neural network (machine learning), neural networks, a class of statistical algorithms, to surpass many previous machine learning approaches in performance. ML finds application in many fields, including natural language processing, computer vision, speech recognition, email filtering, agriculture, and medicine. The application of ML to business problems is known as predictive analytics. Statistics and mathematical optimisation (mathematical programming) methods comprise the foundations of machine learning.
