Introduction:

Cacti is a complete frontend to RRDTool, it stores all of the necessary information to create graphs and populate them with data in a MySQL database. The frontend is completely PHP driven. Along with being able to maintain Graphs, Data Sources, and Round Robin Archives in a database, cacti handles the data gathering. There is also SNMP support for those used to creating traffic graphs with MRTG.

Cacti requirement:

MySQL
PHP
RRDTool
net-snmp
php-snmp
Apache (compiled with php support)

MySQL configuration for cacti:

Code:

[root:~]# mysql -uroot -p

Enter password: 

mysql> create database cactidb;

mysql> grant all on cactidb.* to root;

mysql> grant all on cactidb.* to root@localhost;

mysql> grant all on cactidb.* to cactiuser;

mysql> grant all on cactidb.* to cactiuser@localhost;

mysql> set password for cactiuser@localhost=password('cactipw');

mysql> flush privileges;

mysql> exit

[root:~]#
