Zabbix Hostgroups

In Zabbix, host groups (or hostgroups) are a way to organize hosts (monitored devices or systems) into logical groups. This makes managing and configuring monitoring settings more efficient, especially in larger environments. Hosts can belong to one or more host groups, and host groups allow you to apply common settings or configuration templates to multiple hosts simultaneously.

Here are a few key points about Zabbix hostgroups:

1. Organization: Hostgroups help you group hosts based on similar attributes or purposes. For example, you might create hostgroups like "Web Servers," "Database Servers," or "Networking Devices."

2. Simplified Management: Once you assign hosts to a hostgroup, you can apply templates, actions, and permissions to that entire group of hosts rather than configuring each host individually.

3. Template Association: Hostgroups allow you to link templates to multiple hosts in one go. A template is a set of predefined monitoring parameters (like triggers, items, and graphs) that can be applied to any host in the group.

4. Access Control: Zabbix allows you to control user access to specific hostgroups. For example, you can restrict certain users to only view or modify hosts within a specific group, making it easier to manage large teams or different departments.

5. Monitoring: Hostgroups help in organizing monitoring and alerting based on group needs. For instance, you could define alerts for the "Database Servers" group if performance degrades, and different alerts for the "Web Servers" group.

Example of Usage:

• If you have 100 servers, and 30 of them are web servers, 30 are database servers, and 40 are application servers, you could create three hostgroups named "Web Servers", "Database Servers", and "Application Servers". By assigning these hosts to the appropriate hostgroups, you can then apply specific monitoring rules to each group.

Creating Hostgroups

To create hostgroups in zabbix we need to navigate to Data Collection > Hostgroups section on the zabbix dashboard & then click on Create Host Group on the top right section to create new host groups.

Then we can add the existing hosts on the zabbix dashboard into this group or we can create new host with this host group associated. In the upcoming sections we will learn Autoregistration hosts into the zabbix.
