The new whitelist and blacklist functionality in Zabbix 5.0 may help to secure your environment. Learn how and why using this functionality in the following blog post.
SNMP is one of the most used monitoring types inside Zabbix. But it is also one of the most frustrating tools to configure for newcomers. Even experienced guys tend to make simple mistakes during configuration, which later lead to a lot of issues with flapping items, interfaces, false-positive notifications, or even worse.
Low-level discovery (LLD) functionality allows you to dynamically monitor all your environment for metrics that can change from time to time, and also can be and are different between multiple servers. Zabbix monitoring software will connect to the device, check for entities that exist on it, and based on discovery output create regular items and triggers.
Zabbix comes with an impressive list of supported metrics for virtually all platforms. It covers the monitoring of performance and availability of OS including CPU, memory, network, processes, files, kernel parameters and more. Zabbix also performs agent-less checks for well-known services such as FTP, SSH, IMAP, POP3, HTTP, TCP, etc.
