> Establish some sort of monitoring for the most important assets.
You need this to know if your web sites, servers and services are running, and to be emailed or contacted when not. I am used to Nagios. I understand there is a Nagios fork, Icinga, which I know little about. Some people use Graphite, which I also know little about.
You can also have it check for disks running out, high CPU loads, inodes running out, heavy I/O etc.
Also, you can email etc. alerts, or pay for a company like Amelia to monitor a dashboard and page/call people at night if a server is down, or to even do some simple scripted remediation attempts.
