Are there tools to monitor the status of Linux machines in terms of updates?

Question

linux

As the number of VMs grew, the task arose of updating their software in a timely manner. Everything works in the console, there are no Xs anywhere.
What tools can facilitate their administration?
And then climbing into the console of each of the VMs is already tired and starts to take a lot of time

Answer 1

There are auto-update tools. Perhaps this is what you need?

well, either script the transition via ssh, or script the output of the package list, for all machines, parse the output with a grep.
To the heap, it may be worth setting up a local proxy or mirror for packets in order to save traffic

Answer 2

You can use the utilities built into package managers - for example, yum has yum-cron for yum.
Either Configuration Manager like puppet, chef or another - for centralized patch management.
