ManageEngine - VMware & Hyper-v Monitoring and Troubleshooting

VMware & Hyper-v Monitoring using over 70 performance monitors

ManageEngine offers simple, easy-to-use IT Management products at a price that every business can afford. It is thoughtfully built with SMB’s in mind and eventually scales for large businesses.

VMWare Monitoring with ManageEngine Free VM Health Monitor Tool

ManageEngine VM Health Monitor tool provides an exclusive VMWare ESX ⁄ VMWare ESXi monitoring, as a desktop tool dashboard. It shows the actual resource utilization of the virtual servers alongwith CPU and memory utilization for each guest OS on the VMWare ESX ⁄ VMWare ESXi server. The dashboard quickly shows how many virtual machines are present, how many are powered on⁄off or suspended, how much CPU and memory are allocated to ⁄ consumed by each virtual machine etc., in an intuitive bar graph.

Using the tool, administrator can also set threshold values for CPU and memory usage, like critical and warning thresholds. If at all, the virtual servers behave abnormally and the CPU and memory utilization dangerously crosses the threshold limits, alert signals are shown in the dashboard tool

Key Features of the ManageEngine VMware Monitor (part of Op Manager):

ManageEngine VM Health Monitor helps an administrator to view the following variables of a Virtual Machine server.

• CPU Utilization
• Memory Utilization
• Disk Read / Write
• Network Rx/Tx

CPU Utilization

CPU utilization is approximately equal to the ratio of the used CPU cycles to that of the available CPU cycles. Available CPU = # of physical CPUs x clock rate 100% represents all CPUs on the host are completely occupied. For example, if a four-CPU host is running two virtual machines with one CPU each, and the usage is 50%, the host is using two CPUs completely.

Memory Utilization

Percentage of memory currently in use. This is active memory as a percentage of total configured or available memory.

Disk Read Rate

This parameter provides the average number of KiloBytes read from the disk each second during the collection interval. This parameter is expressed in kiloBytes/sec.

Disk Write Rate

This parameter provides the average number of KiloBytes written to the disk each second during the collection interval. This parameter is expressed in kiloBytes/sec.

Network Rx

Average rate at which data was received during the interval. This represents the bandwidth of the network. The rate at which data is received across each physical NIC instance on the host.

NetworkTx

Average rate at which data was transmitted during the interval. This represents the bandwidth of the network. The rate at which data is transmitted across each physical NIC instance on the host.

Manage Engine Free Hyper-v Performance Monitor Tool

Free ManageEngine HyperV Performance Monitoring Tool provides an exclusive monitoring solution for HyperV server, a Virtual Machine, running on Windows 2008 R2 . This tool shows the actual resource utilization of the virtual servers along with CPU usage, Memory details, Disk and Network utilization of each guest operating system on Microsoft HyperV Environment. The dashboard quickly shows how many virtual machines are present, how many are powered on/off and its severity as Critical or Warning in a elegant TreeView, and also, how much CPU are allocated to / consumed by each Virtual Machine etc., in an intuitive bar graph.

Key Features of the Manage Engine Microsoft Hyper-v Performance Monitor

The ManageEngine HyperV Performance Monitor tool helps an administrator to monitor important attributes of a physical machine running in the Microsoft Windows 2008 R2 using WMI. This tool fetches important information like CPU usage, Memory usage, Disk details and Network parameters from the Windows 2008 R2 hardware.

ManageEngine HyperV Performance Monitoring Free tool helps an administrator to view the following HyperV Performance parameters:

• CPU Utilization
• Memory Utilization
• Disk Read Rate / Disk Write Rate
• Network Rx/Tx

CPU Utilization

CPU Utilization is the current percentage of the total clock cycles being consumed by the virtual system. If a processor of a single VM shows 100% utilization, and the machine has totally 2 physical processors, then we can expect the total CPU load percentage to be around 50%.

Memory Utilization

Memory Utilization is provided as a percentage of memory used to the total memory available in bytes.

Disk Read Rate

This parameter provides the number of bytes read from the disk between the previous refresh operation and the current refresh operation. This parameter will be shown in bytes/KB/MB/GB per second.

Disk Write Rate

This parameter provides the number of bytes written to the disk between the previous refresh operation and the current refresh operation. This parameter will be shown in bytes/KB/MB/GB per second.

Network Rx

Average rate at which data was received during the interval between the previous refresh cycle and the current refresh cycle. This represents the rate at which data is received across each physical NIC instance on the host. This parameter is shown in kbps ( Kilo bits per second).

Network Tx

Average rate at which data was transmitted during the interval. The rate at which data is transmitted across each physical NIC instance on the host. This parameter is shown in kbps ( Kilo bits per second).

List of attributes monitored in a Virtual Machine

The list of parameters monitored by this application for each VM powered on is almost the same as that of the Physical machine.

• CPU Utilization
• Memory Utilization
• Network Rx / Tx

CPU Utilization

This is the host's view of the CPU usage and not the guest operating system's view. It is the average CPU utilization over all available virtual CPUs in the virtual machine. For example, if a virtual machine with one virtual CPU is running on a host that has 2 physical CPUs and the CPU Usage is in the VM is 80%, then only one of the physical CPU is getting the CPU cycles.

Memory Utilization

Percentage of memory currently in use for the VM. This active memory given as a percentage of the total memory.

Network Rx

Average rate at which data was received during the interval between the earlier refresh cycle and the current refresh cycle. This parameter is shown in kbps ( Kilo bits per second).

Network Tx

Average rate at which data was transmitted during the interval. This represents the bandwidth of the network. This provides the rate at which data is transmitted across each physical NIC between the earlier refresh cycle and the current refresh cycle. This parameter is shown in kbps ( Kilo bits per second).
