【HELP】It can not be monitored
Re: 【HELP】It can not be monitored
On the Windows system in the nsc.ini if you are running the older version of NSClient or the nsclient.ini file, you need to add the IP address of the server that is failing and restart the NSClient service.
The setting is allowed_hosts or allowed hosts depending in the NSClient version.
Let us know if this fixed it for you.

Re: 【HELP】It can not be monitored
Hello.
Sorry in clumsy English.
I'm sorry. It is not told well and.
It is itemized, but writes below it.
・C can be monitored from A.
・I cannot watch C from B.
・A and B are using the same cfg file.
・In B, it is synchronized with A.
・The monitoring object except C becomes the result same as A in B.
・I want to know why only C turns out different from A in B.
・Do A and B become the same result if they change which setting?
・Where is the place that you should investigate?
I'm sorry, but will you lend the power?
Thank you in advance.

Re: 【HELP】It can not be monitored
On your windows server being monitored.
C:\Program Files\NSClient++\
In the file nsc.ini or nsclient.ini
There should be:
allowed_hosts=
or
allowed hosts =
This should be a comaseparated list of allowed hosts. 192.168.33.10,10.27.34.2
It should have the IP addresses of both Nagios Servers monitoring it.

Re: 【HELP】It can not be monitored
Hello.
Sorry in clumsy English.
An IP address of A and B is entered in nsc.ini.
NSClient service of C also restarted, but a phenomenon doesn't change.
nsc.ini in C is attached.
ServerA IP=192.168.21.13
ServerB IP=192.168.3.6
Could you check it?

Re: 【HELP】It can not be monitored
The nsc.ini file looks correct.
Can you try the following command from both A and B Nagios servers and post back the results:

Hello.
Sorry in clumsy English.
There were no nmap commands in A and B.

Re: 【HELP】It can not be monitored
You'll need to install nmap.
Then run the nmap commands.
Code: Select all
yum install -y nmap

It appears that server B has no way of getting to 192.168.4.254.P3_25 wrote:Execution result by server B

Perhaps a static route is required?

Re: 【HELP】It can not be monitored
Hello.
The static route was set in neither B nor A.
Still is it necessary?
In addition, is there the place that you should doubt?
