Capacity Planning Blank

[wneville]

Hello,

I have seen several posts about Capacity Planning reports appearing empty and I am having a similar issue. I have >1 year of data and am just trying to get anything to work so for now I have selected the 1 week option for Period.

My log (/usr/local/nagiosxi/var/components/capacityplanning.log) is also empty:

Code: Select all

ll /usr/local/nagiosxi/var/components/*log
-rw-rw-rw- 1 apache nagios 22582 Jul 18 10:32 /usr/local/nagiosxi/var/components/auditlog.log
-rwxrwxr-x 1 apache nagios    25 Feb 14  2022 /usr/local/nagiosxi/var/components/bpi.log
-rw-rw-r-- 1 apache nagios     0 Jan 21  2022 /usr/local/nagiosxi/var/components/capacityplanning.log
-rw-r--r-- 1 apache nagios 12370 Nov  9  2023 /usr/local/nagiosxi/var/components/scheduledbackups.log

Please let me know how I can troubleshoot this.

Thanks

Hey @wneville

Can you go to the capacity planning page and then check your php logs and let us know what you are seeing. Depending on your OS it will be in /var/log/{php-fpm, httpd, or apachex}.

This log entry shows up when I run the report:

Code: Select all

[22-Jul-2024 13:08:30] WARNING: [pool www] child 2622667 said into stderr: "/usr/bin/env: 'python': No such file or directory"

wneville,

It looks like either Python is not currently installed, or there is no symlink to the interpreter in /usr/bin/env/. The package name can change based on distribution, but you will use yum for RedHat based distributions, or apt-get for debian based distributions.

Alternatively, you can attempt to run whereis <python_package_name> to get the install location, then create a symlink in /usr/bin/env/ with a command similar to:

Code: Select all

sudo ln -s <python_interpreter_location> /usr/bin/env/

If you have any questions, let us know.

Best Regards,

Cory Norell

What is being called when I run the capacity planning report? Can I edit that to look for the correct python directory?

[wneville]

Also:

Code: Select all

ln -s /usr/bin/python3 /usr/bin/env
ln: failed to create symbolic link '/usr/bin/env': File exists


ln -s /usr/bin/python3 /usr/bin/env/
ln: target '/usr/bin/env/' is not a directory: Not a directory

[jmichaelson]

The scripts themselves are looking to /usr/bin/env python for the python interpreter. What do you get for output when you run that? Also try as a followup question the same thing but for python3.

[wneville]

Python3 is found but but python is not. That kind of relates back to my earlier question about where the capacity planning report is originating, if it is a script somewhere i could just change the shebang line to /usr/bin/env python3

[ssunga]

Try creating a symlink for python that points to python3:

sudo ln -s /usr/bin/python3 /usr/bin/python

[wneville]

This fixed the issue. Thanks!
