Project Notes
check_disk_inodes is written in Bash and uses df, grep and awk - no Perl, no PHP, no SNMP. This ensures that it is able to run on minimal systems, with few packages installed, and it is compatible with UNIX, Linux and BSD. The thresholds for warning and critical may be specified as integer or float numbers. Performance data: - total number of inodes - currently used inodes as an absolute number - currently used inodes in percents, as a float number Usage: check_disk_inodes [-v] [-h] [-w UsedInodesWarning] [-c UsedInodesCritical] [-p Partition] Options: --version|-v) prints the program version --help|-h) prints this help information -w) warning threshold (in percents without % sign) for used inodes -c) critical threshold (in percents without % sign) for used inodes -p) disk partition to check Example: # ./check_disk_inodes -w 80 -c 90 -p /var OK; /var: total inodes 65536, used 1698 (2.6%), free 63838 (97.4%) | 'used inodes'=1698;52428;58982;0;65536 'used inodes (pct.)'=2.6%;80;90;0;100 ============= Oct. 31, 2014 What's new in version 0.93 - improved error detection. The script exits gracefully if the partition does not exist or it can not be checked or if you simply forget to provide it as an argument. - the path for binary executables is no more hard coded, which makes the script capable to run on virtually any Linux or UNIX system, without the need to edit it. - the path for binary executables (grep, awk, free) can be overwritten in the parameters section, at the beginning of the script

Perfect with a wrapper :)

Hey nice work. I wrote a little wrapper for this to check on every mount point. A little more dynamic for systems where a mount point may get missed by accident. #! /bin/bash # Wrapper script for check_hdd_inodes # Checks all mount points in one easy output if [ $# -ne 2 ] then echo "Usage: $0 [warn %] [crit %]" exit 3 fi loc="/usr/local/bin/check_hdd_inodes" out="" for s in `df -ilP | cut -d"%" -f2 | grep "/"` do getStat=`$loc -w $1 -c $2 -p $s` out=`echo -e "$getStat $out"` done out=`echo "$out" | sed s/"|"/"n "/g` if [ `echo "$out" | cut -d";" -f1 | grep CRITICAL | wc -l` -gt 0 ] then echo -e "CRITICAL: inodes above $1 % threshold. Click service name for more info. $out" exit 2 elif [ `echo "$out" | cut -d";" -f1 | grep WARNING | wc -l` -gt 0 ] then echo -e "WARNING: inodes above $1 % threshold. Click service name for more info. $out" exit 1 elif [ `echo "$out" | cut -d";" -f1 | grep OK | wc -l` -gt 0 ] then echo -e "OK: inodes below thresholds. Click service name for more info. $out" exit 0 fi echo "Oops; something went wrong :(" exit 3
