check_file_exists_glob ERROR: The FILE name must be specifie

[welbp00]

Hi,
this command create's an error i don't understand:

/usr/lib64/nagios/plugins/check_nrpe -H 10.234.nn.nnn -c check_file_exists_glob -a ' -d /waslog -i -w 1 "core*" '

ERROR: The FILE name must be specified.

I start this command on the nagios server. This command works fine on the other server:

./check_file_exists_glob -d /waslog -i -w 1 "core*"

OK: File 'core*' is absent, good.

What am i doing wrong..?

Thanks and regards,

Paul.

[scottwilkerson]

does the other server (10.234.nn.nnn) allow arguments to be passed?

On that server run

Code: Select all

grep dont_blame_nrpe /usr/local/nagios/etc/nrpe.cfg

dont_blame_nrpe needs to be set to 1

If it is, please post the command definition for check_file_exists_glob

[welbp00]

Hi Scott,
thnx for responding.

Yes, the other server is set to allow.
dont_blame_nrpe=1
I am using the command-line to test the command.

It will look like this i think:
command[check_file_exists_glob]=/usr/lib64/nagios/plugins/check_file_exists_glob -d '$ARG1$' -w '$ARG2$' '$ARG3$'

Thanks and regards,

Paul.

Being you are passing the flags in your command I would change this

Code: Select all

command[check_file_exists_glob]=/usr/lib64/nagios/plugins/check_file_exists_glob -d '$ARG1$' -w '$ARG2$' '$ARG3$'

to this

Code: Select all

command[check_file_exists_glob]=/usr/lib64/nagios/plugins/check_file_exists_glob $ARG1$

then restart NRPE

[welbp00]

I have tried it, and this came back: ERROR: the directory must be specified. So i put -d /waslog into the command, and the old call came bak: Error: The file name must be specified.

....help...

Paul.

[scottwilkerson]

Can you show the current nrpe command definition again and what you are testing from the command line?

Also a copy of your plugin check_file_exists_glob would help up be able to test it

[welbp00]

nrpe.cfg:

#command[check_file_exists_glob]=/usr/lib64/nagios/plugins/check_file_exists_glob -d '$ARG1$' -w '$ARG2$' -i '$ARG3$' '$ARG4$'
command[check_file_exists_glob]=/usr/lib64/nagios/plugins/check_file_exists_glob -d '$ARG1$'

from the commandline on the nagios server:

/usr/lib64/nagios/plugins/check_nrpe -H 10.234.42.183 -c check_file_exists_glob -a ' -d /tmp -i -w 1 "core*" '

ERROR: The FILE name must be specified.

On the remote server:

-bash-4.2# ./check_file_exists_glob -d /waslog -i -w 1 "core*"
OK: File 'core*' is absent, good

What I had previously suggested was

Code: Select all

command[check_file_exists_glob]=/usr/lib64/nagios/plugins/check_file_exists_glob $ARG1$

but you used

Code: Select all

command[check_file_exists_glob]=/usr/lib64/nagios/plugins/check_file_exists_glob -d '$ARG1$'

Try

Code: Select all

command[check_file_exists_glob]=/usr/lib64/nagios/plugins/check_file_exists_glob $ARG1$

and restart NRPE

Hi Scott,

doesn't work... Directory and File must be specified.

ERROR: The DIRectory must be specified.

I know trying this:

nrpe.cfg:
command[check_file_exists_glob]=/usr/lib64/nagios/plugins/check_file_exists_glob -d '$ARG1$' -i "javacore*"
Commandline on the nagios-server:
-bash-4.2# /usr/lib64/nagios/plugins/check_nrpe -c check_file_exists_glob -H 10.234.nn.nnn -a -d /waslog -i "javacore*"
OK: File 'javacore*' is absent, good.

But this is not correct, on the other server there is an file javacore*, in the dir /waslog.
Nb i want to get a warning if the file (javacore*, heap* and core*) exists.

Hope you can help me.

Thnx, Paul

I don't understand why you are passing the -d in the arguments when you already have it specified in the command
