NCPA Installtion on Centos7

[sneha.irali]

Hi Team,

We are trying to install the NCPA agent on centos 7 server, however we find that the service is in running state but i also see it s been failed.

Attaching snap FYR.

Our Linux SME has also said that from the ncpa logs , below is the observation, logs snap is attached

The ncpa listener service is not able to start properly as its dependent on the package and the below logs indicate the same.
Without having GLIBC_2.28 it appears ncpa listener won’t start, Kindly check with the Nagios support on how to proceed further as the SOP doesn’t cover this part.
We also want to highlight that GLIBC in turn might be dependent on some other packages for which proper set of instructions are required to fix it at the earliest

CentOS - 7
Nagios version 5.8.3

Hi Sneha,
How are you doing?
Please run the below commands and post all outputs to this ticket:

Code: Select all

cat /etc/centos-release

rpm -qa | grep glibc

ls -l /lib64/libc.so.6

ls -l /lib64/libc*

Best Regards,
Vinh

Hi Sneha,
Hope you are having a good day!!
May I ask, how (what command) used to install the NCPA agent?

I looked at my CentOS 7.8 and also CentOS 7.9, both have the following "glic" RPM packages installed:
glibc-common-2.17-307.el7.1.x86_64
glibc-2.17-307.el7.1.x86_64
glibc-devel-2.17-307.el7.1.x86_64
glibc-headers-2.17-307.el7.1.x86_64

Let remove the NCPA package and try the install again.

Code: Select all

yum erase ncpa

Please run the following commands to re-install the NCPA agent again:

Code: Select all

rpm -Uvh http://repo.nagios.com/nagios/7/nagios-repo-7-4.el7.noarch.rpm

yum install glibc-devel glibc-headers ncpa -y

Configuring NCPA:

Code: Select all

sudo vi /usr/local/ncpa/etc/ncpa.cfg

Find the following line:
community_string = mytoken

Change it to your required token, for example:
community_string = Str0ngT0k3n

Restart NCPA service:

Code: Select all

systemctl restart ncpa_listener.service

Configure Firewall - Linux

Code: Select all

firewall-cmd --zone=public --add-port=5693/tcp
firewall-cmd --zone=public --add-port=5693/tcp --permanent

Test NCPA:
Please replace "x.x.x.x" with the "NCPA IP Address"

Code: Select all

https://x.x.x.x:5693/

Here's the NAPA installation Instruction:
https://assets.nagios.com/downloads/ncp ... g-NCPA.pdf

Hi Vinh,

We dont have internet on the Suse box, how do we proceed then.

[vtrac]

Hi Sneha,
Hope you are having a good day!!

Were there any changes to your OS lately?

Was ncpa working before? .... or this is a new ncpa install?

I don't think it is a good idea to install "GLIBC_2.28".

What version of "ldd" do you have?

Code: Select all

ldd --version

I checked my and it is:

Code: Select all

[root@vt-nagiosxi-62 mrtg]# ldd --version
ldd (GNU libc) 2.17

Also, what outputs do you get for the command below:

Code: Select all

strings /lib64/ld-2.17.so | grep GLIBC

BTW, how did you install "NCPA" on your system anyway?

rpm -qa | grep -i ncpa


Best Regards,
Vinh

[sneha.irali]

here is the response:

Were there any changes to your OS lately? - no

its a new installation.

[root@gmslybf5backup ~]# rpm -qa | grep glibc
glibc-2.17-307.el7.1.x86_64
glibc-common-2.17-307.el7.1.x86_64

ldd --version --> where do i check this on the NAgiosXI machine or the centos box.

NCPA was installed using rpm file, by downloading it to /tmp n then installting.

[vtrac]

Hi,
Please run on the NCPA agent, since that's where your "ncpa_listener" failed to start up.

Please run the below commands on the NCPA agent, as "root" user:

Code: Select all

ldd --version

rpm -qa | grep glibc

rpm -qa | grep ncpa

Also, please run this on NCPA agent as well:

Code: Select all

rpm -ql ncpa

Also, on the NCPA agent, please run:

Code: Select all

systemctl restart ncpa_listener

systemctl status ncpa_listerner

tail -n30 /usr/local/ncpa/var/log/ncpa_listener.log

Please also upload "/usr/local/ncpa/etc/ncpa.cfg" file to this ticket.


Please post outputs or screenshots of ALL those commands above.


Best Regards,
Vinh

[sneha.irali]

sure i will share the o/p

[vtrac]

Great!! ... Thanks ...
