management” chapter in HP Insight Dynamics 6.0 Getting Started Guide.
Create Scenario Wizard not working – requires Adobe Flash Player
The Adobe Flash Player is
delivered with HP Systems Insight Manager software, and assistance is provided to help you
install this plug-in into your browser. If you find that you need more information, please consult
the HP Systems Insight Manager 6.0 User Guide, available from

Data is not being collected
Numerous circumstances can contribute to failure in collecting data.
Data collection not configured and/or agent not installed
Suggested action: For standalone
systems, use the Insight managed system setup wizard to configure the system. The managed
system setup wizard will automatically select the supported data collection method for the
CMS/managed node communication.
For VM hosts and guests, this can mean making sure that the host is licensed for HP Insight
Control virtual machine management (or Insight Control), and making sure that the host is
registered in VMM. Nothing needs to be done for most VM guests, but Microsoft Hyper-V VM
guests must have SSH access set up in HP SIM. Again, use the Insight managed system setup
wizard to set up the VM host or to make sure there are no configuration errors.
TIP:
How to tell whether or not agentless data collection is working
View the utilization meters on
the Visualization tab of the CMS. When meters display data and no errors, then data collection
is configured correctly and working for those systems. Utilization pop-up text from icons to the
right of the meters provide details on errors or warnings encountered. You can also run
capcollect
(or Optimize
→Capacity Advisor→Collect Capacity Advisor Data...) and look
for any errors or warnings in the output. Note that it takes up to 10 minutes after configuring
systems for agentless data collection before data is visible in Capacity Advisor or Virtualization
Manager. (See
“Supported collection configurations” (page 17)
to learn which configurations
will have agentless data collection.)
No network connectivity between the CMS and the managed node
This is often a source of
errors, once a system has been configured and data collection is initially working, but subsequently
fails. Suggested action: Check that the following situations have not occurred:
•
Is the host shutdown?
•
Is the host hung, or otherwise not responding?
•
Has the NIC or NIC driver on the host failed?
•
Is a network cable unplugged from the host or switch?
•
Are there other physical issues (for example, a port on a switch failing)?
•
Are DNS and DHCP working correctly? (the system's IP address is not in use by another
host, for example)
•
Is a firewall blocking connectivity?
Incorrect credentials for the managed node
Suggested action: Confirm that system credentials
are appropriate for the data collection method and the operating system or hypervisor software.
See the HP Insight Dynamics 6.0 Getting Started Guide for information on system credentials.
Unsupported data collection method for the managed node
This situation is less likely with
Insight Dynamics 6.0 release. Suggested action: Make sure the OS is supported for use with
Insight Dynamics.
Collection agents or services are either not running or are hung on the managed system or CMS
Suggested action: For systems using agentless and virtual machine management data collection,
make sure the corresponding services are running on the CMS and are not hung. If it is suspected
