Otherwise, you're probably just aimless.The questions that must be made clear are: What is the performance of the fault? No response? Error? When was the fault discovered?

increase the interval for index refreshesBest practices First of all, your program is going to write logs Log logs to help you analyze the problem, logging only "parameter errors" such as the log is not helpful to solve the problem Don't rely on exceptions, exceptions only deal with places you don't think about. To record key parameters such as time of occurrence, execution time, log source, input parameter, output parameter, error code, exception stack information, etc.

I. Clarify the cause and effect of the problem as much as possible Do not immediately jump to the front of the server. First, you need to understand the number of known conditions on the server and the specific fault conditions. Otherwise, you will probably be in the trouble. The following problems must be clarified: What is the fault? No response? Error? When was the fault discovered? Can the fault be reproduced? Is there a pattern that appears (for example, once every hour

Signs of DDoS attack activity Distributed denial of Service attacks (DDoS) are often used by attackers as smoke bombs to disguise other, more hostile attacks. If businesses find signs of DDoS, such as slow network performance, inability to use a Web site, firewall failover, or a back-end sy

existing enterprise security mode through IPS, IDS, NIDS, and SIEM systems. Mod_security can also be used as a web application firewall. When used for a web application that may not have the best input filtering, it plays a very huge role. Be vigilant By developing these basic measures, enterprises can ensure the security of Apache HTTP servers and provide content at the lowest risk. One of the most important parts of an operating security system is

security personnel, or assess the risks of patches, the final result is likely to be that the new software will have the same problem in the near future. In the field of security defense, technology is very important, but the implementation process of personnel and security work is more important.　　Improper security software setup Information security tools are not a security analyst who can work 24x7 around the clock. If you do not carefully debug the product and make full use of its functions

slower, complex scripts have become increasingly difficult to maintain. Some of these scripts run manually when needed, and many of them run at regular intervals. If they continue, they will be uncontrollable. I am looking for a solution from data entry to data presentation, or share it with experienced students. The log file is stored in a part of hadoop.
