[root@S-BDB-136 ~]# /usr/local/nagios/libexec/check_nrpe -H localhost -c check_disk
DISK CRITICAL - /root/.gvfs is not accessible: Permission denied
用nagios的check_disk可以在本机成功，但是如果用check_nrpe来调用check_disk命令的话就会出现上述错误：

DISK CRITICAL - /root/.gvfs is not accessible: Permission denied
有些人会直接删除这个文件来确保自己监控的成功，但是我觉得这样是不合理的，总不能一言不合就把文件给删了吧。所以，我研究了下可以用下列命令来实现
command[check_disk]=/usr/local/nagios/libexec/check_disk -w 30% -c 20% -X nfs -X mvfs -A -i '.gvfs'
忽略.gvfs，来看看check_disk的参数
[root@bjjk ~]# /usr/local/nagios/libexec/check_disk --help
check_disk v1.4.15 (nagios-plugins 1.4.15)
Copyright (c) 1999 Ethan Galstad
Copyright (c) 1999-2008 Nagios Plugin Development Team
This plugin checks the amount of used disk space on a mounted file system
and generates an alert if free space is less than one of the threshold values
Usage:
check_disk -w limit -c limit [-W limit] [-K limit] {-p path | -x device}
[-C] [-E] [-e] [-g group ] [-k] [-l] [-M] [-m] [-R path ] [-r path ]
[-t timeout] [-u unit] [-v] [-X type]
Options:
-h, --help
Print detailed help screen
-V, --version
Print version information
-w, --warning=INTEGER
Exit with WARNING status if less than INTEGER units of disk are free
-w, --warning=PERCENT%
Exit with WARNING status if less than PERCENT of disk space is free
-c, --critical=INTEGER
Exit with CRITICAL status if less than INTEGER units of disk are free
-c, --critical=PERCENT%
Exit with CRITCAL status if less than PERCENT of disk space is free
-W, --iwarning=PERCENT%
Exit with WARNING status if less than PERCENT of inode space is free
-K, --icritical=PERCENT%
Exit with CRITICAL status if less than PERCENT of inode space is free
-p, --path=PATH, --partition=PARTITION
Path or partition (may be repeated)
-x, --exclude_device=PATH
Ignore device (only works if -p unspecified)
-C, --clear
Clear thresholds
-E, --exact-match
For paths or partitions specified with -p, only check for exact paths
-e, --errors-only
Display only devices/mountpoints with errors
-g, --group=NAME
Group paths. Thresholds apply to (free-)space of all partitions together
-k, --kilobytes
Same as '--units kB'
-l, --local
Only check local filesystems
-L, --stat-remote-fs
Only check local filesystems against thresholds. Yet call stat on remote filesystems
to test if they are accessible (e.g. to detect Stale NFS Handles)
-M, --mountpoint
Display the mountpoint instead of the partition
-m, --megabytes
Same as '--units MB'
-A, --all
Explicitly select all paths. This is equivalent to -R '.*'
-R, --eregi-path=PATH, --eregi-partition=PARTITION
Case insensitive regular expression for path/partition (may be repeated)
-r, --ereg-path=PATH, --ereg-partition=PARTITION
Regular expression for path or partition (may be repeated)
-I, --ignore-eregi-path=PATH, --ignore-eregi-partition=PARTITION
Regular expression to ignore selected path/partition (case insensitive) (may be repeated)
-i, --ignore-ereg-path=PATH, --ignore-ereg-partition=PARTITION
Regular expression to ignore selected path or partition (may be repeated)
-t, --timeout=INTEGER
Seconds before connection times out (default: 10)
-u, --units=STRING
Choose bytes, kB, MB, GB, TB (default: MB)
-v, --verbose
Show details for command-line debugging (Nagios may truncate output)
-X, --exclude-type=TYPE
Ignore all filesystems of indicated type (may be repeated)
Examples:
check_disk -w 10% -c 5% -p /tmp -p /var -C -w 100000 -c 50000 -p /
Checks /tmp and /var at 10% and 5%, and / at 100MB and 50MB
check_disk -w 100 -c 50 -C -w 1000 -c 500 -g sidDATA -r '^/oracle/SID/data.*$'
Checks all filesystems not matching -r at 100M and 50M. The fs matching the -r regex
are grouped which means the freespace thresholds are applied to all disks together
check_disk -w 100 -c 50 -C -w 1000 -c 500 -p /foo -C -w 5% -c 3% -p /bar
Checks /foo for 1000M/500M and /bar for 5/3%. All remaining volumes use 100M/50M
