What are the best OS X programs for administering cloud servers?

Question

ubuntu

At arm's length there is OS X Server 3.1.2
at the other end of the wire, cloud servers on ubuntu (digitalocean, selectel, etc.) work.
I read logs (nginx, php5-fpm, mysql, memcached), update packages and administer them all via ssh, I would like to know the opinion of more knowledgeable specialists - how do they manage dozens of servers? using Ansible is most likely not suitable for this case, since it is more about data analysis and timely response to errors / hacking attempts.
in the answer I would like to see applications with a graphical interface under OS X.

Answer 1

Own scripts + 2 monit-a outside, which check the logs of these scripts (the scripts themselves do some magic there and write OK / not OK).
For parallel execution of commands - dsh, at work - a proprietary craft based on web.taranis.org/shmux
Ansible will also do, but I don't really like its syntax for parallel exec.
In general, your question is about "how do I set up monitoring." There are a lot of ways, there are a lot of ready-made scripts for all cases.
