(Cacti is a graphical analysis tool for network traffic monitoring based on PHP, mysql, SNMP and RRDTOOL. Cacti uses snmpget to obtain data and RRDTOOL to draw graphics. You don't need to know the complex parameters of RRDTOOL. It provides very powerful data and user management functions. You can specify that each user can view the tree structure and ho St and any graph can also be combined with LDAP for user authentication. At the same time, it can also add its own template, which is very powerful and perfect. Friendly interface..........)
