In this chapter you have learned quite a bit about the RRDtool graph generation features.
Specifically you have covered the following:
- Creating some basic graphs using the RRDtool
- Adding advanced features such as threshold line and color changes based on the threshold
- Adding a device to Cacti
- Assigning graphs and interface graphs to a device
- Creating a new Cacti tree containing sub-tree items and devices
You now have a running Cacti server, which is capable of polling and graphing at least one device.
In the next chapter, you are going to learn more on creating and using graph and device templates.
