Summary
What Kibana enables you to do is create custom dashboards that can show you data for different machines side by side, so KVM is just one of the many options we have. Depending on your needs, you can display, for example, disk usage for a KVM hypervisor and all the hosts running on it, or some other metric. The Elastic stack is a flexible tool, but as with all things, it requires time to master. This chapter only covered the bare basics of Elastic configuration, so we strongly recommend further reading on this topic – alongside KVM, ELK can be used to monitor almost everything that produces any kind of data.
The next chapter is all about performance tuning and optimization for KVM virtual machines, a subject that we didn't really touch upon. There's quite a lot to be discussed – virtual machine compute sizes, optimizing performance, disks, storage access and multipathing, optimizing kernels, and virtual machine settings, just to name a few. All these...
