(Cacti obtains data through snmpget and uses RRDTOOL to draw graphics, and you don't need to know the complex parameters of RRDTOOL. It provides very powerful data and user management functions, and 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 templates by itself, which is very powerful and perfect. Friendly interface. The development of cacti software cacti is based on making it more convenient for RRDTOOL users to use the software. In addition to the basic SNMP traffic and system information monitoring, cacti can also plug scripts and add templates to make various monitoring charts. Cacti is a software implemented in PHP language. Its main function is to use SNMP services to obtain data, and then use RRDTOOL to store and update data. When users need to view data, use RRDTOOL to generate charts and present them to users. Therefore, SNMP and RRDTOOL are the key of cacti. SNMP is related to data collection, while RRDTOOL is related to data storage and chart generation.)
