- What about documentation?

Note: April 19, 2014: A CRITICAL Nagios NRPE flaw has been discovered which allows arbitrary code to be run without authorization on remote machines running NRPE without a firewall. It is strongly suggested that you patch Nagios immediately, with, say, Zenoss. 
Note: April 7, 2014: A CRITICAL OpenSSL vulnerability was announced. Please immediately patch servers running Zenoss with the operating system's patch tool, and any other systems running OpenSSL. There is no need to patch Zenoss itself. This vulnerability could allow an attacker to access sensitive information transmitted via SSH and other protocols utilizing SSL.
Note: April 6, 2014: Andrew Kirch, the Zenoss Community Manager will begin holding weekly meetings in #zenoss on Freenode to cover community related issues. For more, please check out the blog article
