> It seems like there are so many choices in each category that there's nothing left to do. Log storage and search for structured logs (e.g. JSON or CEE, not merely stringblobs). We have paid solutions (Splunk, Loggly, Papertrail), and then we have Elasticsearch, which gets worse in this use scenario with every release. Message stream processing engine that doesn't require restarting to add a query or data sink, so you could build monitoring system around it. In fact, a monitoring system designed to allow you to easily add your custom processing or data sink. Infrastructure inventory that can be both filled by hand and kept updated by machine and that can be queried from script or browsed by human. For that it would be useful to have a good topic maps engine, which is another missing thing. OS updates manager that can handle more than just Red Hat/CentOS (Red Hat Satellite or Spacewalk) or just Ubuntu (Canonical Landscape), and while at it, one that doesn't try to be underdeveloped configuration management tool (like CFEngine or Puppet) and underdeveloped deployment tool (like Ansible), but can cooperate with them. And there's much more where these came from.
