NRPE installation on HP-UX

[progressive.nagiosXI]

Hi team,

Can you please help how to install NRPE in HP_UX 11.31 , as we have checked the document but NRPE installation document does not support HP_UX.

Please help!!
Thanks

We don't have anything specific for HP-UX but the generic steps are covered in https://assets.nagios.com/downloads/nag ... e/NRPE.pdf.

With the help of document we tried to install NRPE but didn't get success.
we are getting below error while doing a telnet on the port 5666 to localhost and also from monitoring server (10.100.1.16)
============================================
HECCAPP5:/ #telnet localhost 5666
Trying...

Hi Team,

We have solved the problem it was occuring due to wrong entry in inetd.conf file.

however we are now facing problem that via NRPE monitoring we are not able to pass arguments what we need to do.
we are able to only run command which are defined in nrpe.cfg file.

we have already nrpe.cfg file plz check

command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10
command[check_load]=/usr/local/nagios/libexec/check_load -r -w .15,.10,.05 -c .30,.25,.20
command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/hda1
command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z
command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200


# The following examples allow user-supplied arguments and can
# only be used if the NRPE daemon was compiled with support for
# command arguments *AND* the dont_blame_nrpe directive in this
# config file is set to '1'. This poses a potential security risk, so
# make sure you read the SECURITY file before doing this.

### MISC SYSTEM METRICS ###

command[check_disk]=/usr/local/nagios/libexec/check_disk $ARG1$

please suggest, we would like to share a document of NRPE monitoring here to avoid trouble for any of users.

You already have:

Code: Select all

dont_blame_nrpe=1

in the nrpe.cfg file. Have you restarted nrpe after making these changes?

Note: It is possible that you didn't compile NRPE with the --enable-command-args option. If this is the case, even after setting dont_blame_nrpe=1, you wouldn't be able to pass arguments. You will need to recompile NRPE with --enable-command-args.

# COMMAND ARGUMENT PROCESSING
# This option determines whether or not the NRPE daemon will allow clients
# to specify arguments to commands that are executed. This option only works
# if the daemon was configured with the --enable-command-args configure script
# option.
#
# *** ENABLING THIS OPTION IS A SECURITY RISK! ***
# Read the SECURITY file for information on some of the security implications
# of enabling this variable.
#
# Values: 0=do not allow arguments, 1=allow command arguments
# Values: 0=do not allow arguments, 1=allow command arguments

yes you are right i haven't run with " --enable-command-args "How can i do these please suggest. do i need to uninstall nrpe then install it again or i just need to nrpe directory and run command "configure --enable-command-args"

[lmiltchev]

I don't believe you need to remove the "old" NRPE - just run:

Code: Select all

./configure --enable-command-args
make all
make install

There are some 3rd party plugins on the Nagios Exchange that may work for you. A quick search for hp-us and memory produced the results below:
