i wrote the above script and gave all permitions to it
i placed it in the
/usr/local/nagios/libexec

and gave command
./check_fd -w 600 -c 700
i got out put
ok- 594 no. of openfiles used by java .
here the result is correct

so then i went to the root there i gave
#/usr/local/nagios/libexec/check_nrpe -H localhost -c check_fd
i got

0k- 5 no. of openfiles used by java

if i change the warning value and critical vale the message is not changing with this command
#/usr/local/nagios/libexec/check_nrpe -H localhost -c check_fd

but if go to the libexec folder the i gave
the ./check_fd -w 500 -c 600
i got
warning - 593 no. of openfiles used by java

this the problem.

it works for me.....

Code:

./check_nrpe -H localhost -c check_fd -a 500 600

are you using the -a flag on any of your tests??? if not, look up what it means, and then try it.

Code:

[root@xxxx libexec]# ./check_nrpe -n -H localhost -c check_java -a 300 500
OK - (13)no. of open files used by java

and

Code:

[nagios@ libexec]$ ./check_nrpe -n -H localhost -c check_java -a 300 500
OK - (13)no. of open files used by java

what you are prob missing

Code:

[root@ libexec]# whoami;lsof -c java | awk '{print $1}' | wc -l
root
585

Code:

[nagios@ libexec]$ whoami;lsof -c java | awk '{print $1}' | wc -l
nagios
13

..

Code:

[nagios@ libexec]$ whoami;lsof -c java
nagios

You need to give nagios user sudo access to run the lsof command properly.

type visudo for examples
