It records metrics in a time series database (allowing for high dimensionality) built using an HTTP pull model, with flexible queries and real-time alerting. [ 3 ] [ 4 ] The project is written in Go and licensed under the Apache 2 License, with source code available on GitHub , [ 5 ] and is a graduated project of the Cloud Native Computing ...
In critical real-time system, in which timeliness (i.e., the ability of a system to meet time constraints such as deadlines) is significant, avoidance is the only option. If we, for example, instrument a system for testing and then remove the instrumentation before delivery, this invalidates the results of most testing based on the complete system.
Metric-based monitoring that enables the recording and analysis of time series graphs using a HTML5-based graphing system. An integration with Grafana [ 12 ] is available as well. Log-based and event -based monitoring, in which key events can be filtered out and actions can be triggered based on these events.
Time series datasets can also have fewer relationships between data entries in different tables and don't require indefinite storage of entries. [6] The unique properties of time series datasets mean that time series databases can provide significant improvements in storage space and performance over general purpose databases. [6]
Graphite is a free open-source software (FOSS) tool that monitors and graphs numeric time-series data such as the performance of computer systems. [2] Graphite was developed by Orbitz Worldwide, Inc and released as open-source software in 2008. [3] Graphite collects, stores, and displays time-series data in real time. The tool has three main ...
Critical chain project management is a method of planning and managing projects that emphasizes the resources required to execute project tasks. Program Evaluation and Review Technique , commonly abbreviated PERT, is a statistical tool, used in project management, that is designed to analyze and represent the tasks involved in completing a ...
In manufacturing, an operational historian is a time-series database application that is developed for operational process data. [1] Historian software is often embedded or used in conjunction with standard DCS and PLC control systems to provide enhanced data capture, validation, compression, and aggregation capabilities. [2]
In statistics, trend analysis often refers to techniques for extracting an underlying pattern of behavior in a time series which would otherwise be partly or nearly completely hidden by noise. If the trend can be assumed to be linear, trend analysis can be undertaken within a formal regression analysis , as described in Trend estimation .
