In this chapter, we saw how we can monitor a Proxmox cluster network using powerful monitoring systems, such as Zabbix. By no means is Zabbix the only monitoring option available in the main stream choice. But it does have many advantages over other solutions. The out-of-box features, such as graphing, template, 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 spanned over 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 on what Proxmox can do.
