Hyper-V Environment

Q: What do I need to collect data from a Hyper-V host?

A: Install the Cloudamize Windows agent on your Hyper-V host machine (i.e. on hypervisor) only. This allows Cloudamize to get basic inventory and performance related data.

Q: Do I need to install agents on individual VMs?

A: In order to get data on application interdependencies you will need to install agents on individual VMs. This information is used to build move groups in the Migration Planner.

Q: What is the performance overhead of running agents on a Hyper-V host?

A: The Cloudamize agents are lightweight. Typically it takes less than 0.5% CPU utilization. Cloudamize Agents are Smart Agents. They run two processes. One is the data-collection agent and the other is the watchdog agent. Watchdog agent monitors the data-collection agent and makes sure the data-collection agent is behaving correctly. Watchdog agent monitors every system metric and caps the data-collection agent if it goes beyond expected consumption. If any of the metric is higher than the cap, then data-collection agents sleeps and waits until they can start collecting again. For example, typically, our agents take less than 0.5% CPU utilization. However, if CPU utilization goes higher than 2%, data-collection agents sleeps and waits for watchdog-agent's to tell when to start collection again.

Q: When Cloudamize is assessing locally attached storage for each VM, is Cloudamize agent able to distinguish between locally attached block storage and network attached block storage (for example in-guest iSCSI LUNs)? Or it simply takes all block storage attached to a VM?

A: Currently the Windows Agent only collects any logical disk drives that appears in the "Logical Disk" performance category in Windows. Network Attached Storage isn’t included directly. The same is also true for Linux Agent as well (anything registered as a logical drive is included, NAS is not queried directly), so anything that falls under a logical drive is included in the results. Since we do not collect from NAS directly, we don’t currently distinguish in the results screens.

Q: Will configuring Cloudamize to collect data from VMware and Hyper-V also collect application dependency data?

A. Configuring Cloudamize to collect the data from VMware and Hyper-V will only collect system-level data (CPU, memory, storage, network) as reported by the hypervisor (Hyper-V or VMware).

Data collected using the Agent or Agentless Data Collector methods are capable of capturing the application-level data and dependency data(application interconnectivity, firewall rules, IP and DNS info, installed applications, etc.).
