UPDATE
This patch is included in the nagios-plugins 1.4.0alpha3 release on Nagios Plugins Sourceforge Page.

This patch adds a new option to the check_mysql plugin (-S) that will check the slave status by issuing the command "show slave status'. Additional permissions are required for the user that check_mysql connects as. For MySQL 4.x, the permissions 'usage' and 'super' are required. For MySQL 3.23.x, the permissions 'usage' and 'process' are required. This patch is to be applied against nagios-plugins-1.4.0alpha1.

How to apply the patch

• Unpack nagios-plugins-1.4.0alpha1
• cd into the unpacked nagios-plugins directory
• run patch -p1
• configure, make, etc

New Host/Service Sort
This patch changes the way that Nagios sorts the hosts by default. Instead of doing a straight string compare, it more intelligently sorts hosts and services so that they mimic a phone book type sort. For example, before the hosts host1, host2 and host100 would get sorted as host1, host100, host2. The new sort will sort them as host1, host2, host100.

See last ack comment in status.cgi
When a host or service is acknowledged, the last comment for that host/service will be shows in the host and service lists just below it. This allows you to tell what's going on with that host/service without having to click into it's extended info page. This one is very handy in combination with the next All Problems patch.

New All Problems page in status.cgi
This adds a whole new page called "All Problems" that is a cross between the Tactical Overview and the Status and Host Problems pages. It displays both hosts and services with problems all on one page.
