As the documentation says: Proxy load balancing allows monitoring hosts by a proxy group with automated distribution of hosts between proxies and high proxy availability. If one proxy from the proxy group goes offline, its hosts will be immediately distributed among other […]

One of the built-in security features in Zabbix is TLS (Transport Layer Security) support for external connections. This means that when your distributed Zabbix proxies or Zabbix agents connect to the Zabbix server (or vice versa), TLS can be used to encrypt all the connections. When the connections are encrypted, third parties cannot read the […]

A variety of tools exist that can be used to troubleshoot different Zabbix components. In this article I will demonstrate how Wireshark can be used to rule out network connectivity issues as the root cause of data collection problems.

One of the features of Zabbix proxy is that it can buffer the collected monitoring data if connectivity to Zabbix server is lost. In this post I will show it happening, using packet capture, or packet analysis.

When configuring monitoring and using templates in Zabbix you often see low-level discovery (LLD) used for finding out the monitored components or features of a host. In this post, I will explain how user macros and regular expressions are used in LLD for filtering the discovery results. I’m using the Network Generic Device by SNMP […]
