Description

Im trying to write a custom monitoring plugin but i am having trouble installing the Perl Monitoring::Plugin module.

Can't locate Monitoring/Plugin.pm in @inc (you may need to install the Monitoring::Plugin module) (@inc contains: /usr/local/lib/perl5/site_perl /usr/local/share/perl5/site_perl /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5/core_perl /usr/share/perl5/core_perl) at /usr/lib/monitoring-plugins/check_battery_new.pl line 11.
BEGIN failed--compilation aborted at /usr/lib/monitoring-plugins/check_battery_new.pl line 11.

Im running LibreNMS using Docker compose

Expected behaviour

The script will use sockets to communicate via TCP->Serial and decode the received data. Then it will output the performance data for me to add into graphs.

Actual behaviour

The script should run

Steps to reproduce

Try to use the Monitoring Plugin module

I've figured out how to install the module by doing these steps:

First we exec into the librenms container:
docker exec -it librenms bash

Then we install the following:
apk add perl-dev
apk add perl-app-cpanminus
apk add alpine-sdk
cpanm Monitoring::Plugin

Perhaps we could add to the documentation some examples. One thing i haven't figured out is how to persist these changes across docker restarts. I need to run these commands after every restart of container
