Monitoring VMware ESX servers
All the discovered hosts and VMs are mapped under
'Virtualization' tab. Click on Virtualization
Devices links to access
the dashboard page, which provides a quick
glance of your critical resources such as CPU, Memory,
Network & Disk that are under pressure. Though ideal resource
utilization is the key benefit we get from virtualization, it can lead
to other problems because it is shared among the servers. Even if a
single
system has a resource crunch, it hugely affects the performance of
the other systems running on the same host. Quickly identifying
and fixing the resource
utilization problems is therefore vital for a business to run smooth.
OpManager shows
the top hosts and VMs by resource utilization and the recent alarms
raised. Click on the host or the VM name to see its snapshot page. The
Virtual Devices Dashboard page refreshes automatically every 5
minutes to reflect the
latest collected statistics.
Listed below are the various types of top resource
utilization widgets to quickly identify any over utilized resource. It
gives a quick glance on systems which are the top consumers of CPU,
Memory,
Network, Disk I/O and Disk Space.

Snapshot page of a Host
Snapshot page of Host / VM provides a summary of the current
statistics, recent alarms, configuration details such as VMs inventory,
resource allocation for each VM, Network Adapters, HBA list and
Datastores.
Host Details and Performance Charts
In this section you can find the Host details like IP Address,
Vendor of Host, CPU Cores etc. on the left side. The right side
gives a quick glance on performance data like CPU Utilization, Memory
Utilization, Disk I/O Usage etc., collected during the last poll. These
values are collected at an interval of 5 minutes. These data help you
determine the current performance of the Host.

Host Heath At-a-Glance
This section provides the last one hour performance chart of the Host.
You can view the reports of last 7 or 30 days. Click on 7 or 30 link
available on the top right corner to view the last 7 or 30 days
performance report respectively.

VM List & Resource Allocation
Details
This section lists all the VMs on the Host, resources allotted to each
VM, network adapters, storage adapters and datastore details. Any
change in the inventory, gets updated automatically. You can also
find the monitors that are enabled on the Host and notification
profiles associated to it. Click on the respective tab to view its
details.

Click on the VM name to see its snapshot page. The snapshot
page of the VM is similar to that of any Windows or Linux Server's
snapshot page.
History Reports
OpManager also provides last 12 hour report on CPU, Memory, Disk,
Datastore, and Network usage. Select the required report from the
Select Report drop-down menu. If you want to view the utilization
report
for each VM, select the per VM check box.
