knowledge. You cannot manage something you don’t know. And to stay on that point, since VMware is probably the most popular virtualization technology available, I want to elaborate on VMware capacity planning.
up.time communicates with VMware’s vCenter to get all sorts of data and metrics. For capacity management, we tie all that information neatly into easily digestible reports.
One of these reports is the vSphere Workload Report. It enables you to visually see the resource usage at the data center, cluster and ESX server level as well as resource pools, vApps and the virtual machines. With this knowledge in hand, you can easily determine if you are maxing out your VMware environment or if there’s room to better utilize your resources.
Quite a lot has been said about our capabilities on VMware but that is not the only virtualization technology we work with. Another one that we have coverage for is IBM’s LPARs. The LPAR Workload Report shows the CPU, Memory, Network I/O & Disk I/O for all the LPARs on a pSeries server. The graphs are stacked so not only can you see how the LPARs compare to each other, you also gain insight into the overall workload on your pSeries server. This empowers you to accurately adjust the CPU entitlements of the LPARs and keep track of the overall workload over time!
Capacity planning might sound like a difficult task to tackle but through my last few posts, I hope I have shed some light on how up.time can assist in fulfilling your capacity management needs. If you haven’t already done so, download a free trial of up.time and see what it can do for you!
