In this chapter, we learned about a number of features in Zabbix that allow automatic configuration, creation, and maintenance:
- Low-level discovery or LLD
- Network discovery
- Active agent auto-registration
LLD allows entities to be discovered by using Zabbix agents—it has built-in support for network interfaces, filesystems, and CPUs. We talked about customizing thresholds and other values per discovered entity with user macro context support. Zabbix can also discover SNMP tables, such as network interfaces, but it is not limited to that—any SNMP table can be discovered. We also looked at creating custom discoveries, including MySQL database discovery.
