In this chapter, we learned about several features in Zabbix that allow automatically creating and maintaining configuration:
Low-level discovery or LLD
Network discovery
Active agent autoregistration
LLD allows discovering entities 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 like 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.
LLD offers a way to filter results by regular expressions, and we checked out how global regular expressions can make that easier here and also in other places, such as log monitoring.
After that, we explored network discovery, which is all about scanning an address range and automatically adding hosts, potentially linking them to proper templates and adding...
