Summary

You went through some more advanced topics of Cacti, creating graphs, as well as device and data templates. Specifically, you have covered the creation of basic templates for data sources, graphs, and devices. With data source templates, you can monitor simple SNMP and script-based data, allowing you to immediately start monitoring specific items on your devices. By creating a graph template, you are now able to visualize the data and also create special graphical items to display thresholds and thresholds breached within your graphs. Finally, the creation of a device template allows you to group relevant graphs, for simple selection, for a specific device group such as CentOS servers.

During this chapter, you have also learned how a data query works and how to re-build the interface data query. This will allow you to build more complex queries for a set of items from a device.

You have now learnt the basic Cacti administration tasks for devices, graphs, and templates, so let's move on to the next chapter which deals with Cacti user management and permissions!
