custom_check_mem bug

[pteegarden]

I downloaded and installed the Linux Agent by following the instuctions in http://assets.nagios.com/downloads/nagi ... _Agent.pdf
I installed it on a Red Hat Enterprise Linux Server release 5.8

One of the modules (shell script) that it installs, /usr/local/nagios/libexec/custom_check_mem,
does not report correctly.

# ./custom_check_mem -w 4 -c 3

# ./custom_check_mem -w 5 -c 4

If lines 101 thru 110:

101 if [[ "$percent" -le $critical ]]
102 then
103 string="CRITICAL"
104 result=2
105 fi
106 if [[ "$percent" -le $warning ]]
107 then
108 string="WARNING"
109 result=1
110 fi

are replaced with

101 if [[ "$percent" -le $warning ]]
102 then
103 string="WARNING"
104 result=1
105 fi
106 if [[ "$percent" -le $critical ]]
107 then
108 string="CRITICAL"
109 result=2
110 fi

The module will work better:

# ./custom_check_mem -w 4 -c 3

# ./custom_check_mem -w 6 -c 5

When can we expect an updated linux-nrpe-agent.tar.gz?
