Study Notes
Zabbix 6.0 Certified Professional Day 3
- Discovery Actions include various operations such as adding/removing hosts, assigning/unassigning host groups, and sending messages.
- Discovery Actions involve multiple operation steps that are executed simultaneously without the option to control step execution order.
- Best practices for discovery actions include using data from Zabbix agent/SNMP to link to different templates, setting a reasonable update interval, and matching the number of discoverer processes to the amount of discovery rules.
- Limitations of discovery actions include the lack of support for network topology discovery and encryption in network discovery.
- The practical setup for network discovery involves creating rules for IP range, services, and assigning templates for SSH and HTTP checks.
- JMX (Java Management Extensions) is a technology used to monitor and manage Java applications and resources, with resources registered on the MBean Server.
- JMX monitoring has native support through the "Zabbix Java gateway" and can be used to monitor JMX counters of a Java application.
- JMX monitoring can involve multiple remote gateways, such as Zabbix active proxy, Zabbix Java gateway, and Apache Tomcat.
- To use JMX monitoring, Zabbix Java gateway needs to be installed, started, and configured, and it communicates with the Zabbix server or proxy without encryption.
- Java application configuration for JMX monitoring involves starting the application with enabled support for remote JMX monitoring and configuring security settings for production environments.
- Zabbix server configuration for JMX monitoring includes starting several Java pollers, configuring JavaGateway address and port, and restarting the Zabbix server.
- Zabbix 6.0 Certified Professional Day 3 provides comprehensive insights into practical setup and best practices for discovery actions, as well as JMX monitoring and its configuration.
