Study Notes
Zabbix VMware Monitoring Configuration and Best Practices
- Zabbix provides main templates for monitoring VMware: VMware FQDN and VMware UUID, with specific requirements for monitored VMs and VMware Tools.
- Low-level discovery rule is used to automatically discover VMware clusters, hypervisors, datastores, and virtual machines, with the ability to control monitored parts by disabling discovery rules.
- Host prototypes are used to add new hosts for hypervisors and virtual machines, and datastores and clusters are created as items under the vCenter host.
- Host prototypes are created using low-level discovery rules, and discovered hosts are associated with the LLD rule of the host that created them, inheriting all entities from linked templates.
- LLD macros are used for host name, visible name, host group prototype, interface address, tags, user macros, and a host can be assigned to existing host groups or those created from prototypes.
- Discovered hosts are prefixed with the name of the discovery rule and have read-only configuration options, except for enabling or disabling the host and host inventory values in manual mode.
- Zabbix uses VMware collectors to collect information about virtual infrastructure from vCenter or each hypervisor separately, with up to 2 collectors for each connection to VMware infrastructure data.
- Collected information is stored in VMware cache, updated based on Zabbix server configuration parameters, and polled based on the update interval in item configuration.
- To configure monitoring of VMware, a new host for vCenter or hypervisor should be created, linked to a template named "VMware," and user macros should be defined on the host, using the secret text option for a password.
- Monitoring of VMware data can be viewed in the Hosts Latest data section, and common issues include no data collected due to Zabbix server or proxy configuration, and no new hosts created due to errors in the LLD rules or strange-looking graphs caused by item update interval.
