11 值缓存

    概览

    这个内存缓存,可以用于访问历史数据,而不需要对数据库直接执行SQL调用。如果请求的历史值不在缓存中,则会从数据库请求缺失的数据,并相应地更新缓存。

    有两个内部的监控项来监控值缓存:zabbix[vcache,buffer,<mode>]zabbix[vcache,cache,<parameter>]。查看更多细节,请参阅。

    Value cache status can be observed by using the server runtime control option (or diaginfo=valuecache) and inspecting the section for value cache diagnostic information. This can be useful for determining misconfigured triggers or calculated items.

    Two internal items are supported for monitoring the value cache: zabbix[vcache,buffer,<mode>] and zabbix[vcache,cache,<parameter>]. See more details with .
