The suspicious snmp service is reflected in many software. So we will introduce the Cacti software today. Now I will give a brief introduction to some functions and operations of this software. The Cacti Chinese version is a software implemented in php. Its main function is to use the snmp service to obtain data and then use rrdtool to store and update data, when you need to view data, use rrdtool to generate charts and present them to users. 1. test

IOS-Plist file storage (1), iosplist File 1. What is a file system? In IOS, each app has its own file system and corresponding access permissions, which are generally divided ~ /Documents/ ~ /Tmp/ ~ /Library/Caches/ ~ /Library/Preferences/------- key-value pairs. do not care about the file path. The path is obtained as follows: Plist files can only store NSString NSNumber NSData NSArray NSDictionary co
