How are you installing Nagios XI? Is this a source or a RPM install? Are you using a proxy? Offline environment?

What is the version of Nagios XI that you are installing?

Can you post the entire install log. For the source install, the log should be located in "/tmp/nagiosxi/install.log". For the RPM install, the log should be in "/tmp/xi-install.log".

Thanks!

Hi,

We installed it via curl command directly as customer had allowed temporary internet connection...
Version of Nagios XI should be latest right since we are using the curl command curl https://assets.nagios.com/downloads/nagiosxi/install.sh | sh

Please find the log file attached

install.log

For some reason, you are not able to use pip on this system, which is used to install pymssql. If you don't care about mssql (you are not planning on monitoring MSSQL servers), you could simply comment out this line (about 247) in the /tmp/nagiosxi/1-prereqs file:

Code: Select all

python -m pip install "pymssql<3"

so that it would look like this:

Code: Select all

# python -m pip install "pymssql<3"

Save, exit and rerun the full install from the command line:

Code: Select all

cd /tmp/nagiosxi
./fullinstall

That worked

But what if this was in a scenario where in SQL monitoring was needed... any specific steps are available?

I am glad I could help!

Then, we would had to see why you were not able to use pip in your environment. It could be something specific to your system, e.g. your repos, version of pip that is installed, etc. It's hard to say without getting more info. For example, on my test CentOS 8 system, this particular command works just fine.

Example:

Code: Select all

[root@TEST-XI-CentOS-8 ~]# python -m pip install "pymssql<3"
