NFS mount Script Modification

NFS will certainly be widely used. In addition to network and storage applications, it can often be applied to monitoring modules. Here we will discuss the content of NFS mounting. In the previous article, we have also introduced related scripts. Here I have made some modifications and hope they will be useful to you. If the nfs mounting sequence is not mounted in the order written in fstab, the monitor will issue a warning of warning, but the hard disk information not mounted in the alarm information is empty, actually, all the machines are mounted normally. So I adjusted my script, run the check_mount function in advance, and then judge whether the mount is normal according to the LIST variable content. After the adjustment, the script is as follows:

 
 

  
  
#! /Bin/bash
  
  
 
  
  
# VERSION = "1.1"
  
  
# AUTHOR by wenzizone.cn
  
  
 
  
  
./Usr/local/nagios/libexec/utils. sh
  
  
 
  
  
CHECKNAME = "Mount NFS" // NFS mounting
  
  
 
  
  
RESULT = ""
  
  
EXIT_STATUS = $ STATE_ OK
  
  
 
  
  
NFSFSTAB = 'lc _ ALL = C awk '! /^ #/& Amp; $3 ~ /^ Nfs/& $3! = "Nfsd" & $4 !~ /Noauto/{print $1} '/etc/fstab'
  
  
NFSMTAB = 'lc _ ALL = C awk '$3 ~ /^ Nfs/& $3! = "Nfsd" & $2! = "/" {Print $1} '/proc/mounts'
  
  
 
  
  
Theend (){
  
  
Echo $ RESULT
  
  
Exit $ EXIT_STATUS
  
  
}
  
  
 
  
  
CHECK_MOUNT (){
  
  
LIST = ""
  
  
For list in $ NFSFSTAB
  
  
Do
  
  
NFS_MOUNT = $ (LC_ALL = C cat/proc/mounts | cut-d ""-f 1 | grep "$ {list} $ ")
  
  
If [-z "$ {NFS_MOUNT}"]; then
  
  
LIST = "$ LIST $ list"
  
  
Fi
  
  
Done
  
  
}
  
  
 
  
  
If [-n "$ {NFSMTAB}"]; then
  
  
CHECK_MOUNT
  
  
If [-z "$ {LIST}"]; then
  
  
RESULT = "$ checkname OK-NFS BE MOUNTED PROPERLY"
  
  
EXIT_STATUS = $ STATE_ OK
  
  
Else
  
  
RESULT = "$ checkname warning-$ {LIST} not be mounted"
  
  
EXIT_STATUS = $ STATE_WARNING
  
  
Fi
  
  
Else
  
  
RESULT = "$ checkname critical-all nfs not be mounted"
  
  
EXIT_STATUS = $ STATE_CRITICAL
  
  
Fi
  
  
 
  
  
Theend
 
 

In this way, NFS mount monitoring should be okay.
