What would be good to receive mail about the status of the linux server to the admin?

Question

linux

I wrote a small script for myself (for ubuntu), which daily sends information about the system to the mail about the presence of open ports, a list of users that are in the system, anti-virus check information via clamav, temperature, backup logs, welcome information when logging into ubuntu ( how much memory is used, how much is logged in, disk size, IP, etc.), size of mounted HDDs in % and some other points.
I wrote this script for myself and posted it on github . What else can be screwed on that would be useful?

Answer 1

What you will use, why receive a bunch of useless data that you will stop even reading after a month, as you play enough. Monitoring should notify about anomalies, and not spam the owner, for example, you don’t monitor traffic in any way and don’t monitor updates, judging by the description, but what should be up to you to decide.

Answer 2

Look at ready-made templates for nagios for example.

Answer 3

most of everything is in monitoring systems, they are generally not difficult to set up and do not spam for no reason, why do you need letters with all this information, do you read it every time? and if there are hundreds of servers? and if you don’t get a grasp of it, but nafig in general such letters are needed.
