The Cfgmaker program in MRTG can only create profiles on the network interface and simultaneously listen for two kinds of object identities: the uplink and downlink traffic statistics for the network card. It then determines what kind of data is recorded in the data directory based on the configuration file. Indexmaker also uses these profiles to create an overview file, or a summary View Web page that is identified by the MIB object you are listening to. The Summary View Web page displays only the daily statistics. You can choose Summary View chart to get ...

Until Windows 8, Microsoft did not provide an AppStore like Apple, so on this platform to develop and use the software there is a certain threshold: For ordinary users, specifically went to the electronics market to buy a set of office or entertainment Software CD-ROM is not something everyone likes, and even in the less healthy software development environment in China, to the major software Web site to download non-toxic software is not an easy task for developers Even more so, not only to consider the various functions expected to complete the software development, but also deal with such as packaging ...

The hardware environment usually uses a blade server based on Intel or AMD CPUs to build a cluster system. To reduce costs, outdated hardware that has been discontinued is used. Node has local memory and hard disk, connected through high-speed switches (usually Gigabit switches), if the cluster nodes are many, you can also use the hierarchical exchange. The nodes in the cluster are peer-to-peer (all resources can be reduced to the same configuration), but this is not necessary. Operating system Linux or windows system configuration HPCC cluster with two configurations: ...

Q: Pool teacher, I am not an interactive person, but you have all the articles I read, thank you very much for your guidance, I started the life of the first MBP. Now the problem is, but you can't find the right person to answer, only you, if you have time. The problem is this: I have a 32bit Unix file (open a service process), and the error message on the MAC is: Exec format error, but it can be performed on a Linux server, why? Is there a scenario on the MAC that you can run? Period ...

A discussion about Microsoft Windows and Linux based operating systems is sweeping the internet. The discussion involved many people with vested interests and partiality. The discussion was heated by the confusion of the discussion due to the lack of understanding and misunderstanding caused by logic mistakes. The demand for advertising strategies is expected to give the sponsors more attention, and the use of collated statistical data in the allocation of papers is too obvious authority and objectivity to support the discussion with prejudice and questionable facts. Part of the reason for this lack of certainty is that the debate seems to be never-ending, partly because of the safety of ...

One, the charm of the management of cloud computing is that users can start using their ID card and credit card, but that's the problem. Such a simple service is bound to bring many challenges to the unprepared IT department. 　　We've been through this many times before: the benefits of a technology that are easy to use end up being an unexpected management challenge, such as virtualization, which causes virtual machines to become fragmented, new security risks to smartphones, and instant messaging that triggers corporate governance problems. This article is intended to show IT managers how to maximize cloud computing ...

Henry and I are working on an examination of the big data and its true meaning. Large data is a popular language. As with many popular words, the word "big data" is a bit overused, but it contains some real usability and technology. 　　We decided to analyze the big data on this topic and try to find out the authenticity of it and what they mean to storage solutions. Henry started this series with a good introduction. His definition of big data is the best definition I have ever seen. So I'm going to repeat this definition: Big data is turning data into information ...
