In this chapter, we saw how we can monitor a Proxmox cluster network using powerful monitoring systems, such as Zabbix. The only monitoring option available as a mainstream choice, but it does have many advantages over other solutions. The out-of-the-box features, such as graphing, templates, SNMP, auto notification, and so on, are just the tip of the iceberg of what Zabbix has to offer. Whether it is a small environment or a large cloud service provider spanning multiple regions, Zabbix can monitor them all. A good network administrator will try a few solutions and find the one that suits their environment best.

In the next chapter, we will see some complex production-level virtual network environments leveraging Proxmox as a hypervisor. We will take a look at a scenario-based network diagram to gain knowledge of what Proxmox can do.
