Description:
This script generates a health check report similar to that of vmwareHealthCheckScript but for the new vSphere release of VMware ESX(i) 4.x/5.x and VMware vCenter 4.x/5.x and it's managed entities. User's can now fully customize the report based on the categories that are of importance to their operating environment, including selecting specific set of ESX(i) hosts and/or Virtual Machines.
The script reports on the following:
- New vCenter Information including InstanceUUID and hostname
- New Storage DRS Configuration
- New FDM/HA Heartbeat Policy and State
- New Host details (Host Agent, iSCSI, FCoE, Source Packages, Capablities, SMC Hardware, Host Cache, DVS)
- New Virtual Machine details (HW Version, Firmware, Overhead Memory, Swap, State, Snapshot Consolidation, HA Protection, EZT Disks)
- New updated Color mappings for mulitpath states
- New Support for Standalone ESX(i) hosts without vCenter Cluster
- New updated Color scheme for HTML Report
- DRS GROUP/VM Rules
- HA Configuration Issues
- COS VMDK Information
- Storage I/O COntrol Information
- Host Authentication Services
- VM count per datastore
- VM count / VM-to-Host Ratio in Cluster Section

Email report
./vmwarevSphereHealthCheck.pl -server VC_SERVER --username VC_USERNAME --password VC_PASSWORD --type vcenter --email yes
Note:
Ensure that you have all the email variables configured either within the script or in the external configuration file, else the report will not be sent.
Hostd Log
To specify the number of the latest lines in the hostd logs, use --logcount \[number_of_lines\]
(e.g.)
./vmwarevSphereHealthCheck.pl -server VC_SERVER --username VC_USERNAME --password VC_PASSWORD --type vcenter --logcount 20

To collect basic performance stats from all Clusters, note that the duration of the script may potentially increase. Only use if you need and by default it's disabled.
(e.g.)
./vmwarevSphereHealthCheck.pl -server VC_SERVER --username VC_USERNAME --password VC_PASSWORD --type vcenter --clusterperforamnce yes
Host Performance Stats
To collect basic performance stats from all Hosts, note that the duration of the script may potentially increase. Only use if you need and by default it's disabled.
(e.g.)
./vmwarevSphereHealthCheck.pl -server VC_SERVER --username VC_USERNAME --password VC_PASSWORD --type vcenter --hostperformance yes
VM Performance Stats
To collect basic performance stats from all VMs, note that the duration of the script may potentially double. Only use if you need and by default it's disabled.

-
Custom Report Configuration
There are 54 parameters that can be configured to display various categories of the health check report. By default, everything is set to "yes" except the following 4:
CLUSTER_PERFORMANCE
HOST_PERFORMANCE
VM_PERFORMANCE
VM_DELTA
as these can potentially increase the amount of time the report takes to generate.
