In "Template App Zabbix Proxy", trigger "Less than 25% free in the configuration cache" suggests to increase CacheSize in zabbix_server.conf. It should suggest to increase this parameter in zabbix_proxy.conf instead. Ideally, for consistency, other triggers in both proxy and server templates should suggest to increase their respective parameters.
In "Template App Zabbix Agent", one trigger refers to "zabbix_agentd" and another refers to "zabbix_agent(d)". Same for items. Should be consistent.
