So it’s not in a centreon directory, it’s the direct nsclient++

but

Tx

ok, so you don’t use the centreon-nsclient package which comes with some pre configured stuff

i have no idea what is not working here, the last thing I could is based on the previous screenshot (command not found on “check_service”) is that the “checksystem” module is not pre-loaded

it is in the the nsclient.ini, in a section called 

[/modules]

; CheckSystem - Various system related checks, such as CPU load, process state, service state memory usage and PDH counters.
CheckSystem = 1

that’s the module you loaded manually in the debug console just above.

if this is missing, add that line “CheckSystem=1” to the /modules section and restart the nsclient service
 

Hello

CheckSystem=enabled change something not 1

But now i have a socket timeout for bothe commands

CHECK_NRPE STATE CRITICAL: Socket timeout after 10 seconds.
root@centreon-central plugins]# ./check_nrpe -2 -H srv-dial2 -c check_service
CHECK_NRPE STATE CRITICAL: Socket timeout after 10 seconds.
root@centreon-central plugins]#

Any idea?

Hello,

So sorry o totally missed you latest reply, thant you first of all

It seems to work

load CheckSystem
D       core Loading module C:\Program Files\NSClient++\modules\CheckSystem.dll ()
L        cli CheckSystem loaded successfully...
D  w32system Loading counter: disk_queue_length_0 C: = \\SRV-DIAL2\PhysicalDisk(0 C:)\% Disk Time
D  w32system Loading counter: disk_queue_length__Total = \\SRV-DIAL2\PhysicalDisk(_Total)\% Disk Time
check_cpu
L        cli OK: OK: CPU load is ok.
L        cli  Performance data: 'total 5m'=0%;80;90 'total 1m'=1%;80;90 'total 5s'=3%;80;90

Hello, anyone could help? :)

hello

what is the status now, your last post said it worked.

as you did lots of things I’m having trouble following where you are and what is working or not

Hello,

Looks like doing the test on the machine itself work

load CheckSystem
D       core Loading module C:\Program Files\NSClient++\modules\CheckSystem.dll ()
L        cli CheckSystem loaded successfully...
D  w32system Loading counter: disk_queue_length_0 C: = \\SRV-DIAL2\PhysicalDisk(0 C:)\% Disk Time
D  w32system Loading counter: disk_queue_length__Total = \\SRV-DIAL2\PhysicalDisk(_Total)\% Disk Time
check_cpu
L        cli OK: OK: CPU load is ok.
L        cli  Performance data: 'total 5m'=0%;80;90 'total 1m'=1%;80;90 'total 5s'=3%;80;90

But remotely no

lroot@centreon-central plugins]# ./check_nrpe -2 -H srv-dial2 -c checkservice
CHECK_NRPE STATE CRITICAL: Socket timeout after 10 seconds.
troot@centreon-central plugins]# ./check_nrpe -2 -H srv-dial2 -c check_service
CHECK_NRPE STATE CRITICAL: Socket timeout after 10 seconds.
troot@centreon-central plugins]#

ok, so it was working before you did something, I think you reinstalled the nsclient agent on the windows host if I remember correctly

now you have a socket timeout, be sure on your windows machine that only 1 nsclient agent is running (process nscp.exe) 

be sure it is listening on the default port 5666 (you can see that in the performance monitor, network section, listening port, you should have a line “nscp.exe” listening on port 5666

also check this page : NRPE - NSClient++ it tells you what to look for in the nsclient.ini to be sure that all is setup correctly in that file so the check_nrpe command can work correctly.

I don’t know what is not working on your setup, usually you should use the “plugin pack” (or “connector”) from centreon to do these checks, but you are trying to make you checks manually, this needs a bit of knowledge on how nrpe and nsclient are working

if you look at the centreon doc : Windows NRPE 0.5 | Centreon Documentation the command line options have an additional parameters that is needed because the nsclient.ini that comes with the centreon package of nsclient needs an extra “ -P 8192 “ (capital P for “payload size”)  (and a “-u” option which I don’t remember what it does exactly)

also check the “allowed_host” option in the .ini, this is the thing protecting your host from accepting nrpe command from a random ip address, be sure that this value is defined in your .ini and has the ip address  of your poller (or its dns name)

Hello not really, it never worked.

It’s a fresh new install of the nsclient on the windows machine on whish a did enable the check

So on the machine itself it seems to work, but not remotely

Tx

I’ll take your advices and check them out

Tx

Well well well, i don’t really understand what’s happening here, there’s nothing listening to the 5666 port, i change the local account of the service to networkd account and also used a domain user , still not listening

Looks like my ini file is ok, it’s basic the one from default with the check_service enabled

Here’s my ini.

# If you want to fill this file with all available options run the following command:
#   nscp settings --generate --add-defaults --load-all

No idea what i made wrong, i of course checked the windows fw

from the doc https://docs.centreon.com/pp/integrations/plugin-packs/getting-started/how-to-guides/centreon-nsclient-tutorial/#nrpe

the allowed host is normally in the nrpe/server section, 

(be sure to restart the windows service to be sure the modification is taken into account)

and if you use “payload length = 8192” in the .ini like in the doc, you must set “ -P 8192” in the command line

also you should have a “nsclient.log” in the program files directory, check there if there is an error message when you start the service

Nothing seems to work here for me :) 

I’ll leave it like that, tx for trying :)

good day

Well i did investigate a little more and make it work a little better

 I can do that remotely now

>root@centreon-central plugins]# ./check_nrpe -2 -H srv-dial2
I (0.5.2.41 2018-04-26) seem to be doing fine...
>root@centreon-central plugins]# ./check_nrpe -2 -H srv-dial2 -c check_service
CRITICAL: GoogleUpdaterInternalService132.0.6806.0=stopped (auto), GoogleUpdaterService132.0.6806.0=stopped (auto), RemoteRegistry=stopped (auto), WbioSrvc=stopped (auto), delayed (BITS=stopped (delayed), edgeupdate=stopped (delayed), gupdate=stopped (delayed), MapsBroker=stopped (delayed), sppsvc=stopped (delayed))

So i think it can works

Now i just cannot put an argument after the check_service

I start from here

https://nsclient.org/docs/reference/windows/CheckSystem/#check_service

so 

./check_nrpe -2 -H srv-dial2 -c check_service service=snmp must show something no?

seems i’m missing something

/root@centreon-central plugins]# ./check_nrpe -2 -H srv-dial2 -c check_service service=nscp

Any idea of what i am missing?

Hello

so i can do this

./check_nrpe -2 -H server -c check_service

I have a list of services

But i cannot speciofy a service

./check_nrpe -2 -H server -c check_service service=xyz isn’t working

From the host it works

check_service service=lanmanserver
L        cli OK: OK: All 1 service(s) are ok.
L        cli  Performance data: 'lanmanserver'=4;0;0
 

I don’t know what i am missing
