File System Monitoring

F u n c t i o n s

When File System Monitoring function detects space capacity lack of file system mounted by a system, this

function does an alert report to a syslog to record and NEC ESMPRO Manager of the detection information.

You can confirm a short mount point of the space capacity when you refer to NEC ESMPRO Manager.

When it meets all the following conditions, File System Monitoring function is targeted for monitoring.

- In the case of the following file system device types

ide, rd, sd, sr, md, ramdisk, dac960, DAC960, device-mapper, dd.

*1 The device type identifies mount point (/etc/mtab), judges a device type from disk I/O information

(/proc/diskstats) and block device (/proc/devices). The mount point is based in order of

/etc/mtab. When it does bind mount, this is given priority to information of bind mount.

In the following examples, the device type of sda1 and sda2 is "sd". /home of sda3 is bind mount, and

a file system type becomes "none". It becomes out of a monitoring object.

Block devices:

8 sd

- In the case of the following file system types.

affs, coda, ext, ext2, ext3, ext4, hfs, hpfs, jfs, minix, msdos, ntfs, reiserfs,

sysv, ufs, umsdos, vfat, xfs, xiafs

The movement of the following file system has been inspected.

ext2, ext3, ext4, jfs, minix, msdos, ntfs, reiserfs, vfat, xfs

The movement of the following file system is non-inspection. Because a kernel supporting is included in

the old file system and has been inspected movement in the past version, these are targeted for

monitoring logically.

affs, coda, ext, hfs, hpfs, sysv, ufs, umsdos, xiafs
