Happy new year!
Let's discover a new cool feature of Xen Orchestra: combined pool statistics. It means, in your XenServer pool view, there is a new "Stats" tab:
What about it? It combines all your hosts stats to make a great recap of what's happening in your pool!
From a really simple things to compare (load average or RAM):
To more subtle stuff, like network and CPU usage:
For CPUs, the sum of all cores usage for each host is made (therefore explaining the scale here at 400%)
For network, all RX for each host are combined, same for TX
And guess what: it's already available in the today's patch release!
This is another step to improve your understanding of all your XenServer hosts. Enjoy :)
