You can use Cacti to gather any sort of data, or fetch information from [SNMP] capable hosts.
-To 'manually' handle data gathering, you can feed cacti the command line for any external script/command along with any data that the user will need to "fill in" (IP addresses etc). Cacti will then gather this data in a cron-job and populate a MySQL database/the round robin archives.

MySQL]
database/the round robin archives.
Data Sources can also be created, which correspond to actual data on the graph. For instance, if a user wants to graph the ping times to a host, they could create a data source, choosing a script that pings a host and returns it's value in milliseconds. After defining options for [rrdtool] such as how to store the data you will be able to define any additional information that the data input source requires, such as a host to ping in this case. Once a data source is created, it is automatically mantained at 5 minute intervals.
For people who are used to creating traffic graphs in [MRTG], this process has become much simplier in cacti. An [SNMP] interface allows you to enter SNMP capable hosts and cacti will display that host's interfaces, all of which can be graphed with once click from that point.
