  • APC Smart-UPS 3000 XLM SNMP - monitoring of APC Smart-UPS 3000 XLM by Zabbix SNMP agent;
  • APC Smart-UPS RT 1000 RM XL SNMP - monitoring of APC Smart-UPS RT 1000 RM XL by Zabbix SNMP agent;
  • APC Smart-UPS RT 1000 XL SNMP - monitoring of APC Smart-UPS RT 1000 XL by Zabbix SNMP agent;
  • APC Smart-UPS SRT 5000 SNMP - monitoring of APC Smart-UPS SRT 5000 by Zabbix SNMP agent;

  • TiDB TiKV by HTTP - monitor TiKV server of TiDB cluster via HTTP.

See setup instructions for HTTP templates.

You can get these templates:

  • In ConfigurationTemplates in new installations;
  • If you are upgrading from previous versions, you can download new templates from Zabbix Git repository or find them in the templates directory of the downloaded latest Zabbix version. Then, while in ConfigurationTemplates you can import them manually into Zabbix.

Value cache performance

The value cache performance has been improved by replacing mutexes with read-write locks in the processing logic. The expected benefit of this change is reduced history syncer usage in heavy parallel workloads.

Diagnostic information

Diagnostic information about preprocessing has been improved to include the oldest values in queue and the totals to include done, queued, processing and pending.

Real-time export

Severity is now exported for trigger events in real-time export.

VMware discovery

The vmware.vm.discovery item, used for virtual machine discovery, now returns an additional field {#VM.FOLDER} with the chain of virtual machine parent folders.
