In all APC templates, the discovery rule for external defective battery packs has been supplemented with a filter to avoid creating unsupported items.
In the templates MSSQL by Zabbix agent 2 and MSSQL by ODBC, a timeout has been added and certain item keys have been adjusted to increase monitoring stability.
You can get these templates:
In Configuration → Templates in new installations;
When upgrading from previous versions, the latest templates can be downloaded from the Zabbix Git repository and manually imported into Zabbix in the Configuration → Templates section. If a template with the same name already exists, check the Delete missing option before importing to achieve a clean import. This way the items that have been excluded from the updated template will be removed (note that history of the deleted items will be lost).
