Next, I wrote a blog about influxdb and how to install it. This blog introduces how to install telegraf in Linux and its features... Official website address: influxdata Official documentation: telegraf documentation Environment: centos7.4 64-bit Influxdb version: 1.0.2 1. Introduction to telegraf 1. Basic Introduction Telegraf is a go agent that collects statistics on systems and services and writes them to the influxdb database. The memory usage is small. You can easily add extensions that su

In the development of video conferencing systems, we must ensure the reliability of audio and video data, because the video conferencing system is a very real-time system, if the network is not good, packet loss, data delay, and data congestion may occur, which may affect

After you click the desired data, the data is written to the current input box.Separate them with commas (,). When the input is continued, the background processes the output data for selection.Next let's look at the example, html code The code is as follows:Copy code Ajax Real-

First, the advantages and disadvantages of rsync Compared with the traditional CP and tar backup methods, Rsync has the advantages of high security, fast backup, support incremental backup, etc., through rsync can solve the real-time requirements of the data backup, such as regular backup file server data to the remot

persist in the local file system (poor performance).5.Flume Overall Architecture IntroductionThe flume architecture as a whole is Source-->channel-->sink's three-tier architecture (see figure one above), a structure similar to that of the generator and the consumer, which is decoupled through the queue (channel).Source: Completes the collection of log data, divided into Transtion and event into the channel.Channel: A function of a queue that provides

This article by show according to Lin Feng to provide friendship sponsorship, starting in the mud row world. In the previous article we described how to use rsync synchronization files, this article we will introduce, how to integrate rsync and inotify to achieve real-time data synchronization. To achieve this goal, we need to take the following steps: 1, the adv

IBM InfoSphere CDC is a powerful data real-time replication software that is not only widely used for heterogeneous platform integration of traditional ODS, data warehouses, data marts and BI systems, but also provides full support for cloud, and for various cloud scenarios,

Recently in the group made a simple sharing, the topic is the real-time data stream processing, the main point is the recommendation system in a variety of real-time data stream real-

This article describes how to install rsync and sersync in linux to implement real-time data synchronization. I. Why should I use the Rsync + sersync architecture? 1. sersync is developed based on Inotify and is similar to Inotify-tools. 2. sersync can record changes (including adding, deleting, and modifying) in the monitored directory to the name of a specific

In addition, rsync + inotify enables Real-time Data Backup Advantages and disadvantages of rsync Compared with traditional cp and tar backup methods, rsync has the advantages of high security, fast backup, and support for Incremental backup. rsync can meet the demand for data backup with low

My first blog, in this has been the help of everyone, but also hope that they can learn to pass on to those in need. Recently in doing will vs and MATLAB for real-time transmission of data, mainly using UDP. Why UDP, and the benefits of UDP are no longer in the details here, you want to see the following references to the blog. The following is a separate vs. C #

After you click on the desired data, the data is written to the current input box and separated by commas (,). when the input continues, the background processes the output data for selection. let's take a look at the example. the html code is as follows: metahttp-equ... after you click on the desired data, the

(including add, delete, modify) a specific file or a directory name; (2): Rsync in sync, only the change of the file or this directory (each change in the data relative to the entire synchronization directory data is very small, rsync in the traversal lookup than the file, fast), therefore, high efficiency. Summary: When the volume of synchronized directory data
