VMware released a minor upgrade for Hyperic yesterday - release notes are here.
Starting with the 5.0 release, VMware made a vApp version of Hyperic available. If you have deployed a previous version of the Hyperic and want to upgrade I have already documented the steps in a previous post - see here - but you will need the 5.8 package of course.
Be sure to grab the hyperic-hqee-installer-x86-64-linux-5.8.0.tar.gz from VMware downloads - the screen cap below shows the exact listing in the file downloads area that you will need.
There's another file for Linux, the RPM, that won't work.
The complete upgrade process from the VAMI looks like this...
