dataset. Sometimes, you need a complete point-in-time view of the data that a query returns. For example, a query to monitor memory utilization should return a complete picture each time it runs. Osquery supports this type of scheduled query with the"snapshot"parameter in the query's ...
This practice is not unique to Unix; you’ll still find many new Windows systems with several partitions on a single disk. In addition, most systems have a separate swap partition. 注意在拥有大容量硬盘的系统上,多个数据分区曾经很常见,因为旧的个人电脑只能从硬盘的某些部分启动。 此外,管理员使用...
