Munin is not standard plotting?

Question

bash

Good day to all ... Everything is immediately clear and do not throw sticks ... For my insignificant requests, it is simply irrational to install aggregates like Nagios and Zabbix.
In general, help me somehow get to the bottom of the truth ... There is a meaning ... It changes constantly ... And it’s not logical to shoot it every 5 minutes ... It’s more logical to shoot it every 5 seconds ... or better, once every 1 second ... Storage does not matter ... I need what if these values ​​would appear on the chart at the time of updating munin itself, that is, once every five minutes... Since munin takes one value... I find it difficult...
Either I didn’t read the documentation or my brain just doesn’t get it...
There is 1 example of how to work with this:
github.com/munin-monitoring/contrib/blob/master/pl...
But not strong in bash...
do not scold ... I myself know that hoopoe ...
