19 vfs.dev.get 的返回值

概述

本节提供 vfs.dev.get 监控项的返回值详情。 该监控项在 Linux 上由 Zabbix agent 和 Zabbix agent 2 支持，在 AIX 上由 Zabbix agent 支持。

详情

此监控项返回名称与给定正则表达式匹配的块设备的详细信息。

输出结构为一个 JSON 对象，包含 config，以及根据 <mode> 参数不同而包含的 values 数组。

config 数组包含所选模式可用的属性。values 数组仅在提供块设备统计信息的模式下返回。

不可用的指标会从 JSON 输出中排除。

以下各节描述了每种模式返回的属性。
