查了一下，zabbix 3.0改了规则，可能需要重新制作一个模板了，或者看看能不能批量替换
参考：
https://www.zabbix.com/forum/showthread.php?t=52651 https://www.zabbix.com/documentation/3.0/manual/discovery/low_level_discovery#discovery_of_snmp_oids
Zabbix has changed SNMP OID discovery in 3.0. You can refer to https://www.zabbix.com/documentation...y_of_snmp_oids for reference.
For example, if you want to discover fans, you need to set SNMP OID to "discovery[{#SNMPVALUE},1.3.6.1.4.1.9.9.13.1.4.1.3]" in your discovery rules instead of "1.3.6.1.4.1.9.9.13.1.4.1.3".
Hope it helps.大体的意思是将自动发现的key改成discovery[{#SNMPVALUE},oid]
