Logical Disk \% Free Space

Microsoft.Linux.SLES.9.LogicalDisk.PercentFreeSpace.Monitor (UnitMonitor)

SUSE Linux Enterprise Server 9 Logical Disk \% Free Space 监视器

Knowledge Base article:

摘要

该监视器检查所有逻辑磁盘的 Disk % Free Space。如果收到监视器发出的警报，则必须采取措施以释放磁盘空间并且将系统恢复到操作状态。

原因

不正常的状态表示当前 % Free Space 为低。这可能是由于某一应用程序过多登录所造成。

解决方法

在 Operations Manager 控制台下查看磁盘容量。确定最近是否安装过新的应用程序。检查过大日志的日志文件。如果是，确定是当前日志还是历史日志。

要纠正此情况，应考虑使用 tar 实用程序来压缩日志文件并且释放磁盘空间。要创建 tar 文件，使用命令‘tar –cvf [目标文件名].tar [源路径/文件]’。
