First, the vApp upgrade steps in the "Getting Started with vFabric Hyperic 5.7 Guide" don't tell you which file (of the dozen or so available on the VMware download site) to use. You want to grab the file hyperic-hqee-installer-x86-64-linux-5.7.0.tar.gz for this upgrade.
You will need to place the file on an FTP or Web server you can access from the Hyperic vApp. You will be using the VAMI interface at https://
Here's a screen shot of the install - be sure to get a snapshot of your Hyperic VMs before starting the upgrade! These screens show you all you need to know....
|Starting the upgrade....|
You may want to upgrade your agents - there are some fixes for a couple of the plugins, most notably Windows AD 2008 monitoring is finally working! Thankfully, this is a pretty pain free process as well. What I recommend is to create a group for all of the HQ Agent "servers" so you can upgrade at one time.
To do this, you select "New Group" from the Tools menu under the Browse tab - as below.
Now I can select that group, and click the "ADD TO LIST" under the Resources table....
...and move them over to the right hand "Add Resources" table and click "OK"
Now you are ready to upgrade the whole group, by selecting "Views" and then "Agent Commands" for the group. The agent operation you want is, of course, "upgrade"
